    martymil started a thread Hows this for an IC in N54
    Hows this for an IC, biggest tube and fin that can be crammed into a 1 Series period and some results from the third back to back run at 400rwk on dyno dynamics dyno and the dyno room tipping the temp at 100f And it only weighs 13 lbs http://www.datazap.me/u/martymil/log...g=0&data=1-4-6

    I recently had my friend (Engineered Mechanic Mike) do a M3 LSD swap into my 335i. I am a single turbo N54 with 6MT, and put around 700hp to the ground. I wanted to do a LSD swap because even with 265 R888R's out back, most of second and all of first gear were useless. I do most of my work myself when time permits, but since this involved shortening the driveshaft and changing bushings I asked Mike to take it on (he is a mechanical engineer by trade, and knows his BMWs!)I decided to do the M3 LSD swap instead of a Wavetrac/Quaife for a few reasons: Way cheaper Reliability & tech of a M3 diff, plus added cooling with the M3 diff heatsink. The new pumpkin is a beast compared to the 335i one. M3 half shafts and driveshaft are way beefier than 335i. No need for DSS axles (save $1000). No deductibles or cores to send in when done. I can resell all my old parts! This wouldn't have happened without the excellent threads by Theconnman2 and GeorgeSmooth on e90post. These guys rock, and hopefully this post adds to their already awesome work. I started by researching all the parts they listed, and then by buying off eBay and craigslist. I also found some parts at online scrap yards, but was able to find cheaper stuff on the other two sites. Any of them should work though, so do whatever you find easiest. Final parts list (for me). Your list will be different!: M3 half shafts from 2011 (right/left). - $359 shipped - Found some that came with the proper bolts and retainers, which saved me $150. If you're getting these pulled for your build, GET THE BOLTS. Your 335i ones WON'T FIT. These are much more beefy than 335i half shafts, so you get a free upgrade here and no need for DSS axles. M3 DCT driveshaft. - $200 shipped - Came with guibo and center bearing. M3 DCT differential from 2008. - $580 shipped - Must be DCT for 6MT cars, as it maintains a (close) to stock 3.15 ratio. Note that these may require special balancing bolts or washers, depending on the paint mark on the differential. I was lucky and mine had a white paint mark, meaning no balancing hardware was necessary. Hardware Driveshaft gasket - 26117507842 - $8.85 Bolts - 26117526322 - $23.64 Bolts - 26117527475 - $33.96 Nuts - 26127536563 - $9.00 Retainers - 33212283013 - $16.68 New differential bushings (not necessary, but a good idea) - Rear PowerFlex PFR5-1226 - $48.99, front PowerFlex PFR5-426 - $50.99. Labor - $600 Driveshaft rework - $100 So my total for parts was $1231, labor was $600, and driveshaft rework was $100. To put one of the other LSD options in comparison, we will just stick to parts/rework cost without bushings. Labor will be really variable. On N54Tuning, the Wavetrac for my car (2009) would be $2694.00. Then you send back the core, and total is $1499+$35 shipping + $85 core shipping return = $1619. So I only saved about $288 to start with, but in the process I got upgraded and beefier half shafts, an upgraded and beefier axle, and a much beefier LSD/pumpkin with heat spreader than the LSD replacements for the 335i pumpkin. Seems like a no-brainer to me. OH, and I get to sell all my old parts and probably get a lot of money back! So now that the costing/parts are done, here are the install pics. We will be doing a write-up soon as well, but this install is a bit more difficult due to needing bushing removal tools and a good way to remove axles (air hammer in our case). Pics: On the "lift" and ready for swapping. Giant nuts on the 335i driveshaft to diff connection. These require a really big wrench. Make sure you measure your driveshaft lengths BEFORE removing anything, as you will need those lengths to have the new driveshaft reworked. Center support bearing unbolted M3 diff/driveshaft on the left, 335i on the right. Notice how much bigger the M3 differential is, and how much more beefy the heatsinks are? Here you can (kinda) see that the front half of the M3 shaft is longer than the 335i one. This is why it needs to be reworked by a professional driveshaft shop. This is after the driveshaft was reworked. The front flange from the 335i is different than the M3, so the M3 front shaft needs to be cut down and shortened, and then have the 335i flange welded on. Here are my lengths, but yours will be different. Do not use these measurements before checking yours personally. Hard to tell here, but the flanges are slightly different sizes. Need to make sure you 335i one is used for the finished driveshaft. These are the two center support bearings. 335i on the left, M3 on right. You will need to put your 335i one on the driveshaft you are having reworked/balanced. The M3 one sits lower, so can't be used or your angles won't be right! M3 axle (bottom) vs 335i axle (top). The M3 half shaft is MUCH beefier. Old bushings coming out... New (stiffer) bushings going in... M3 diff in place. Notice the giant heatsink on this guy. Much nicer than the 335i pumpkin, which you won't get if you just do a Wavetrac/Quaife swap... That's it! The car now gets some traction in 1st, and hooks pretty well in 2nd. Way better than it was before. Also feels substantially better in corners than it did before the swap. I know a lot of people argue that a LSD isn't needed since we have the BMW braking assist to "simulate" a LSD, but to be honest it feels totally different. Well worth the money. Hope this thread helps! Josh

    This is going to be ready to go in about a week but the video posted claims 'DCT like' shifting. Based on what though? Because they think it shifts faster? There is literally no measurement of any kind provided to corroborate that and it just seems to be hype: Ok, so the shifts are firmed up a bit (nowhere near a DCT from that vid) but what else? Where is the full control? Programmable shift points and so forth? You can see at the end of the video the car revving out slightly higher. What's the big deal here?

    BimmerBoost and the BoostAddict Automotive Performance Network as a whole takes pride in having great vendors who are enthusiasts at their core. The automotive world is riddled with scammers and this website has turned away and reported on a fair share. Unfortunately, JPWorkz is one that got on this board and never should have been allowed here in the first place. Call me naive but I believe people are ultimately good natured and in this because they love cars. I can not imagine taking in orders and then just blatantly ripping people off for thousands of dollars. How do you live with yourself? Well, perhaps if you have been doing it for over a decade you become numb to it. JPWorks or @JerryT introduced himself to me and pretended to offer a complete N54 turbo upgrade kit for a very low price. If something is priced too good to be true, it usually is. I would periodically receive messages telling me this Jerry fellow was a scammer known as Shaudfab. My initial thought was that maybe other vendors did not like someone coming in and pricing a turbo upgrade so low that it undercut them. I gave the guy a chance to prove himself but it soon became apparent a person named Jerry Trance was not reputable and likely did not even exist. The red flags were there after a few months. There is a 48 page thread you can go over and read for yourself but let's summarize things for those of you who don't have buckets of popcorn and hours to spare. I'll start with my personal experience that this guy always had an excuse. He never was able to pay his vendor tab on time. Literally, he never did. When he finally did the payments would come from someone named Anika Briton as he said he had no Paypal account. Huh, what? No Paypal account? Oh, I get it now, he didn't want a payment trail tied to him: Notice the payments cancel frequently as the account never was able to maintain payments. Also notice the dates constantly vary as it was like pulling teeth to get this person to maintain their account. Basically, all he wanted was to pay some money, put up a thread, collect orders, and run away with as much money as possible. Eventually JerryT told me he would pay for a block of time in advance. I took him at his word. Guess what happened? He did not honor his word. Suddenly things got very weird with this Shaudfab involvement: His 'girl' is somehow involved with Shaudfab who is well known as a scammer: http://www.boostaddict.com/showthread.php?71356-JP-WORKS-SHAUDFAB Things get very dirty the deeper you look: http://www.srtforums.com/forums/f110/fraud-alert-guy-keikei-aka-04srt405-aka-amanda-mabalot-aka-kashif-casteel-141225/index9.html#/forumsite/21161/topics/141225?page=1 He doesn't just scam auto parts but everything: https://www.techpowerup.com/forums/threads/ton-4-sale-4850-q6600-4gbram-28-monitor-hd-bluray-cases-mothe-rboard-and-more-look.72296/page-32 Those posts are dated as far back as 2005 meaning this person has been scamming on forums for well over a decade. Not to mention, getting away with it. He has it down to a science it seems. This information is actually common knowledge. People have messaged me confirming all of it but are afraid to take it to the police or have their name attached to it. Just look at this guy: Tracking down information on this guy is actually quite difficult as he has perfected his scamming technique to make sure he can't be found. Well, maybe perfected gives him too much credit: Now we're starting to get somewhere. These fake names keep popping up but they are tied to Bakersfield and a certain address. At the very least there is an address tied to the names. Two fakes names for shipping, but the same address. A place for the FBI to start, right? There are those who defend him saying this is all hate because his 'kit' is priced so cheaply but there sure is a long trail of people saying they got scammed: We could go on, and on, and on, and on... but it's time for this to come to an end. There is simply a constant pattern of missing parts, kits not being shipped, missed dates, broken promises, stolen money, etc. I am not a detective and neither are car enthusiasts on this forum. There is more than enough here for the FBI to do a proper investigation. This forum will gladly provide all the PM's, IP addresses, and e-mails from the JerryT account if asked. What I can say is that no vendor providing so little information about who they are will ever be allowed here again. Those who were scammed, provide the FBI with the information at the following link: https://www.ic3.gov/default.aspx Let's finally make sure justice is served and that law enforcement properly investigates. It's the least we can do.

    We all knew it was just a matter of time. Being the first Nissan GTR to crack the 6's is a huge deal. Various tuners have battled for the honor over the past year but only one could claim the crown. Congratulations are in order to AMS Performance. The GTR is tuned on a Syvecs ECU but further details beyond that are hard to come by as the record pass happened not too long ago. This thread will be updated with details on the Alpha Performance Alpha G GTR by Diamonds by Wire Racing as they come out. What we do now is the car managed an insane 1.213 60 foot time and broke into the 6's at 196.27 miles per hour. Just a crazy fast achievement and it deserves all the credit in the world.

    You may remember this 550i from a video earlier this month where it pulled away from a stock F10 M5. Additionally, last month on the dyno with JB4 tuning the car produced 511 rear wheel horsepower and 621 lb-ft of rear wheel torque. Well, with the addition of their BCM (Boost Control Module) BMS is able to increase horsepower to 570 at the wheels and torque to 632 lb-ft at the wheels: That is a big change in power and it is maxing out the 2.5bar TMAP sensor according to Terry@BMS: It looks like there might be more in it. The curve isn't the prettiest and it pretty much is all about gains down low with peak horsepower coming in the mid-range and falling off toward redline. A turbo upgrade might do this car wonders.

    So close to the 10's you can just feel it. You can also bet this car will be in the 10's soon as these runs were made at full weight and 1275 feet of density altitude. What makes this impressive is the S4 is still using the factory 1.32 liter Eaton blower. That is where the APR dual pulley system and Ultracharger throttle body upgrade come into play in order to squeeze every ounce of performance from the SC unit. You may be asking, how did APR almost cut a half second in elapsed time from the 2014 S4 that ran 11.5 @ 121 with these upgrades? Well, this car utilized their race gas tune as well as a more aggressive pulley setup among other things: 2012 Audi S4 (B8) 3.0 TFSI S Tronic APR ECU Upgrade - Stage 2+ Ultracharger APR TCU Upgrade APR Ultracharger Throttle Body Upgrade APR Supercharger Drive Pulley APR Supercharger Crank Pulley APR Coolant Performance System APR Intake System 2.5 Exhaust System with Testpipes Street Tires Full Interior Sunoco GT260 Plus To think they are about to get 10's out of the car on the factory blower using boost only and no nitrous is incredible. APR has literally pushed it to the maximum.

    This is great news considering basically every tuner PorscheBoost has spoken to is saying the 991.2 Carrera ECU's are proving problematic. GIAC apparently solved the encryption but the ECU needs to be shipped to them in order to be programmed. GIAC claims gains of 85 crank horsepower and 105 lb-ft of torque. The problem is they do not provide raw dyno graphs but just give us these crank overlays (which we do not want): What is going on here GIAC? Just show us the raw graph at the wheels as you do on every previous release. Until we get a graph, we'll have to take GIAC's word for the gains with their correction factor applied but the 991.2 Carrera S is picking up 100 lb-ft of torque and almost 100 horsepower tune only. They also only are supporting the Carrera S at this time with 991.2 Carrera and GTS support to follow.

    GAD Motors produces some incredible Mercedes-AMG builds and products. Unfortunately, documentation is not their strong suit and dyno runs as well as information on their builds are hard to come by. This particular C207 E-Class coupe gets an M157 swap. Mercedes-AMG regrets not building an E63 AMG Coupe for the C207 generation. GAD Motors steps in to fix that. The M157 gets forged internals and a displacement bump from 5.5 liters to 5.8. As far as further details, GAD Motors doesn't provide any. They refer to this as their 'Stage VIP' level which is another way of saying you better have a ton of money. They certainly provide a good amount of power for whatever it is the build costs. They hit 1049 horsepower and 1050 lb-ft of torque at the crank: You can see an acceleration video of the car below although it is not on the race gas tune in the above dyno run: Certainly quick although it doesn't quite look like 900+ horsepower. It would be great to see what it runs in kill mode in the 1/4 mile although the owner probably isn't one of those people who cares about providing data. An impressive engine swap and build regardless.

    My 1 year old oem clutch and flywheel has started slipping at 20psi on pure stage 2 and just ordered stage3+ and SMFW. After much research I've found out that the metal TOB is supposed to be a POS and a new oem clutch fork and TOB is the better option? Is this still the case or do I take the risk and put the TOB that spec supplied and reccomends? Any feedback from long term users regarding the stage3+ with the metal TOB or the oem piece? Any info would be great.

    Great news for BMW F87 M2 owners looking for quite a bit more power and torque out of their M2. The chassis of the car is capable of handling much more power than BMW gives it but we all know it can not be allowed to encroach on the mighty M3/M4. Well, in comes VF-Engineering to the rescue with Stage I and II Hex Tuning software. Let's start with taking a look at Stage I on a Dynojet in STD and uncorrected plots: You see a big torque gain before 3000 rpm and gains throughout the curve which level off toward redline. The N55B30T0 is not exactly a classic M top end design but it sees over 400 lb-ft of torque at the wheels with just the Stage I tune. Now let's look at Stage II: The Stage II software picks up 52 peak wheel horsepower but the torque gain is a massive 78 lb-ft at the wheels. The peak torque figure is an incredible 442 lb-ft on the Dynojet. That is something you are going to feel. I can say that with certainty as I went for a ride in VF-Engineering's Hex Tuned M2 and it is very stout down low. It pushes you into your seat right away. Does it pull like a freight train up top? No, but that is the nature of the N55B30T0 engine. The software complements the factory curve and just gives you more of everything including more power in the upper rev range where it is desperately needed. The software is not just about power and torque gains but offers additional features such as a limiter delete, throttle overrun (exhaust burble), start up roar, and an increased power level on the Sport Display. It all felt very OEM and worked perfectly. You wouldn't want a stock M2 after trying it out, let's put it that way.

    The current S55 motor in the F80 M3 and F82 M4 is a powerhouse of an engine but it suffers from certain design issues. BMW supposedly resolved those issues but the S55 engine is getting a revision and new designation for the F97 X3 M and F98 X4 M models. It is interesting to note BMW is likely to continue with the 'S' designation here for M motors despite saying they will not longer use it. The reasoning in this application is likely because the S58 is a revision of the already 'S' designated S55. If it was a revision of the B58 engine, you likely would not see the 'S' designation. BMW is expected to increase the power to 450 horsepower but we all know the S55 motor already produces more than 450 horsepower. The reason for this increase will likely be to give the motor more torque to move heavier X SUV's which will also be sending power to all four wheels through an automatic. That means a less efficient drivetrain than the dual clutch and rear wheel drive F80 M3 and F82 M4 models. It is possible BMW equips the new M SUV's with a dual clutch transmission but considering that they are going to an automatic for the upcoming all wheel drive M5 and that the X5 M and X6 M both utilize automatic gearboxes prepare to be disappointed. Expect more details as we get closer to the 2019 model year launch.

    Grand_hustle17 started a thread Smoking at start up in N54
    I am getting a very annoying smoking on start up that I cannot seem to figure out... Here are some of the things I did that did not help what so ever lol Valve cover gasket Replaced all 6 injectors 24 spark plugs (they kept blowing out.. now using NGK 5992). 6 Coil pack with all of this the car still smokes at start up, did a compression and a leak down test (mechanic did) all of which came back within spec. I am thinking there is something small that I am overlooking or just don't know but this is driving me crazy. I've thought of valve seal but I thought leak down test would've reveal that issue. I am single turbo and have stock exhaust cats, I am wondering could they just have been bad??... the car only smokes after 3 minutes of start up then it goes away, but once its parked for 10minutes or more there will be a smoking on start up again. consumes oil extremely fast. I am at a lost outside of just replacing the whole darn engine:angry-banghead: lol. and if I see 1 smoke cloud I feed it with a lil bit of fire to help itself :laughing-rofl:

    We have several guys overseas so this might help them. I don't know this company or have any result to share but it may be worth looking into: Says a Stage 3 TDO4 option is in development as well.

    PTF (Pro Tuning Freaks) is really impressing with their Bootmod3 tuning software on a variety of BMW platforms. Look at these OTS (off the shelf) tuned S63TU results with just the Bootmod3 Stage 1 pump gas ECU flash. 609 rear wheel horsepower and 592 lb-ft of torque at the rear wheels. Incredible numbers for just a flash. Now, in order to use the PTF Bootmod3 software and do OBD-II flash tuning (which also allows remote tuning like the F10 M5 in the article) the ECU must first be unlocked. After it is unlocked, you can then get custom dyno tunes, do OTS tunes, downpipe tunes, race gas tunes, etc. Whatever you want the car to be tuned for really. Then again, you can just set it forget it with an OTS map and enjoy an immensely powerful car. The Bootmod3 FAQ is here: https://www.protuningfreaks.com/pages/bootmod3-faq

    A recent article about a Mustang dyno run for the Alfa Romeo Giulia Quadrifoglio exposed a large flaw in traditional dyno thinking. On this website most readers know that you can not just grab a graph from one type of dyno and compare it to another dyno and expect the numbers to be uniform. Unfortunately, the average person does not understand this which is what led to someone putting out an article stating the Giulia Quadrifoglio is not making its stated output which sets understanding of dyno runs back instead of helping educate. Let's start with the idea that cars suffer from 15% drivetrain losses. Where did this idea start? Why is it 15%? It originated with the Dynojet and became a rule of thumb on automotive forums for manual transmission cars. The percentage changes based on if the car is automatic (20%) or even all wheel drive and automatic (25%). The problem here is that while the conversion factor works well to extrapolate crank horsepower from peak Dynojet figures at the wheels that is not the way drivetrain losses work. First of all, losses are not static. There is no one set figure for losses. What does this mean? It means that your losses in 5th gear at 8000 rpm will be different from 2nd gear at 2000 rpm. The loss figure will change based on rpm, load, and even what accessories are running. Stating all manual cars suffer from a single set figure is flawed for this reason. Not to mention that figure only works on the Dynojet which is inertia based. BMW M cars used to follow the number exactly back when they were naturally aspirated: E46 M3 S54 Displacement: 3.2 liter Horsepower: 343 Torque: 269 lb-ft Wheel Horsepower: 280 Wheel Torque: 235 E92 M4 S65 Displacement: 4.0 liter Horsepower: 414 Torque: 300 lb-ft Wheel Horsepower: 350 Wheel Torque: 254 lb-ft 85% of 414 horsepower is 351.9. Notice the E92 M3 is almost exactly at 15%. DCT models would actually dyno slightly less than manual examples due to the wet clutch dual clutch having higher losses. For the E46 M3 85% of 333 horsepower is 283.05. Again, the E46 M3 is almost perfectly at 15% losses on the Dynojet. It's almost scary how consistently close BMW was to this figure. Now, in comes the turbo era. Let's see what happens when we get to the F80 M3. F80 M3 S55 Horsepower: 425 Torque: 406 lb-ft Wheel horsepower: 427 Wheel torque: 429 How is the S55 engine producing more horsepower at the wheels than it is rated at the crank by BMW? Does the F80 M3 have a magical transmission with negative losses that somehow adds power? Of course not. The DCT transmission in the F80 M3 works the same way as the DCT transmission in the E92 M3. What happened was the 15% Dynojet loss rule went out the window when the turbo power war started. BMW is able to claim a lower number to not push an output war on paper yet delivers far more where it matters, to the tires. The drivetrain losses are still about the same for the transmission and rear wheel drive layout as the previous generation despite it no longer lining up with the crank horsepower figure which is practically meaningless. How does this all look on a Mustang load bearing or eddy current variant? Well, very different. While the Dynojet is spinning a drum of a set weight and calculating the result based on how quickly that weight is spun the Mustang dyno creates load. Why is this important? Because it simulates real world conditions which is great for tuning. A tuner can provide all kinds of different scenarios. The spool on the Mustang for a turbo motor will look different than on a Dynojet. Often time real world spool is much quicker than what is shown on a Dynojet graph due to load which generates exhaust gases more quickly for the turbochargers. Note: Dynojet operators can optionally eddy current load control as well which muddies comparisons further. The other day BimmerBoost posted an article on VF-Engineering's F87 M2 ECU flash software and provided Dynojet runs. Let's take a look at the same M2 running the same Stage I software on a Mustang: Now the Dynojet: 269 rear wheel horsepower for the Mustang and 331 rear wheel horsepower for the Dynojet on the baseline figure. That is a difference of 62 horsepower at the wheels or 18.7 %. If you take that 18.7% difference and apply it to the tuned run on the Mustang which shows 287 to the wheels you get 354 horsepower. Almost exactly what the Dynojet tuned run shows. This is not an exact science as you can see. However, if you were to dyno cars all day on the Dynojet and on this Mustang you would see the runs follow very closely to the ~18% difference between the two. So is that it? Just convert Mustang runs by 18.7% to get a Dynojet number? No. Things actually get very muddied due to the games tuners play. Here is an example. The new Porsche 991.2 Carrera S on a Dynojet: 380 horsepower to the wheels. Now here is a 991.2 Carrera S on a Mustang from AWE-Tuning: Why does the Mustang dyno show more power now? Because it is being corrected to read higher. People do not like low numbers and high numbers are better for marketing. BoostAddict asked AWE-Tuning what their correction factor is but they would not share it with us. You can see it is reading VERY high and higher than a Dynojet though. In this instance it is better to focus on the delta which you will often hear tuners say. That means the difference between the two runs as comparing the peak figures to other runs on other dynos is pointless due to the unknown correction factor. Good for marketing, bad for those who want relevant figures to compare with. It can also be very bad for consumers. Why is that you ask? Because some people will dyno without a correction factor and then change the correction factor to show larger gains. A good example of someone who plays with the numbers is Vivid Racing: http://www.bimmerboost.com/content.php?4252-Inflated-numbers-Vivid-Racing-claims-407-wheel-horsepower-for-exhaust-and-VR-ECU-tuned-E9X-M3-S65-on-a-Mustang-dyno They claim 407 wheel horsepower for an exhaust and canned tune on a Mustang dyno for the E92 M3. Anyone who has an E92 M3 (like me) and has had these modifications and dyno'd the car knows this is impossible. It looks good for someone who doesn't know that though and wants to buy parts thinking they make a ton of power, right? Always keep in mind when you see figures from a company or tuner you should question them. Independent runs are the best to go by as the person usually isn't trying to sell you anything but just share their results. Also remember the Mustang can be configured like most dynamometers to read whatever the operator wants it to read. If vendors and tuners did not play with dyno runs for sales we would have a great resource to work with for comparisons and so forth. You can not trust all tuners to do so. Fortunately, VF-Engineering has no dog in the fight and provided us with a variety of runs showing the difference between their Mustang and their Dynojet. Yes, they have both. That is the proper way to do it. One dyno for tuning and one for marketing. Rather than correcting figures with whatever percentage generates the most sales they show the uncorrected runs on both machines so people can learn from and reference the pulls. BMW 335i (N55) Stage TWO Dynojet: Mustang: An 18.2% difference between the peak horsepower on the tuned figures. There will be variance from run to run, day to day, fuel to fuel, gear to gear, etc. Ultimately, remember, while dyno runs can tell you a lot about a motor or modifications they can also mislead people. Even worse, people can read them incorrectly and spread misinformation or manipulate them to sell parts. A dyno is just one, albeit important, piece of the performance puzzle.

    Guys, at what power or torque levels are the following components good for on 335's? Drive shafts Prop shaft AT MT DCT Standard diff large type 215 Standard diff small type 188 I was wondering myself. At what torque rating the teeth on the drive shafts might get stripped for example.

    camberadam started a thread WTF gas tank?! in N54
    After beating my head against a wall for 3 hours trying to get the top hat notch to line up, I think I discovered a factory Friday flaw... All pics online show the notch @ approx 1-2 oclock. Notice mine is more in the 10-11 range. I THINK this is what was causing all my issues (none of the internal plumbing fit). Makes sense if the pump is clocked almost 90* out... The "notch ring" appears to be separate from the tank itself (notches/tabs molded into tank 90*). I tried prying up on it a little to reclock it, but stopped before disaster. looking at diagrams, I can't buy it. And as far as the top hat that came off the car, it does look like the area above the notch has been rubbed harder by the retaining ring. This makes me think they just cranked down on the retainer ring a little harder. 1. Am I correct or just need sleep? If I decide to trim the top hat & make it work (I REALLY don't want to drop the tank to try & separate the ring from tank) I need to know how to orient the pump. 2. Are the 2 hoses in the top hat parallel to centerline of car (that makes the float arm run almost perfect L & R)? Or off slightly?

    The current S55 motor in the F80 M3 and F82 M4 is a powerhouse of an engine but it suffers from certain design issues. BMW supposedly resolved those issues but the S55 engine is getting a revision and new designation for the F97 X3 M and F98 X4 M models. It is interesting to note BMW is likely to continue with the 'S' designation here for M motors despite saying they will not longer use it. The reasoning in this application is likely because the S58 is a revision of the already 'S' designated S55. If it was a revision of the B58 engine, you likely would not see the 'S' designation. BMW is expected to increase the power to 450 horsepower but we all know the S55 motor already produces more than 450 horsepower. The reason for this increase will likely be to give the motor more torque to move heavier X SUV's which will also be sending power to all four wheels through an automatic. That means a less efficient drivetrain than the dual clutch and rear wheel drive F80 M3 and F82 M4 models. It is possible BMW equips the new M SUV's with a dual clutch transmission but considering that they are going to an automatic for the upcoming all wheel drive M5 and that the X5 M and X6 M both utilize automatic gearboxes prepare to be disappointed. Expect more details as we get closer to the 2019 model year launch.

    bigdnno98 started a thread E90,E91,E92,E93: E92 tow hook front plate holder in 3 Series and M3
    Well I need to put a front plate on my car, here in Italy. I know BMS has one that screws into the tow hook, but I don't know if it'll get here in time. Does anyone know if BMW has one that screws into the tow hook? That way I can grab one at the dealer here? I'd call, but I doubt anyone will speak English there.

    An 11 second SUV with just a BMS JB4? Yes, that is exactly what we have here. The E70 X5M is a beast stock but as well know the S63 4.4 liter twin turbo V8 platform can make big power. Keep in mind this is not even the updated S63TU V8 from the new F85 X5 M but the original S63 V8. On a 93 octane pump and E85 mix the owner managed an 11.728 @ 117.11 and a 11.8203 @ 118.13: The 60 foot on the quicker run dropped down to 1.6860 which is a very strong launch for a 5300+ pound German tank. Now imagine what it could do with a turbo upgrade...
