    We thought this would be a fun comparison. MOTIV recently got an M4 and dynoed it to get a baseline before parts development starts out. How does it stack up in stock form against an N54 with the MOTIV 750 single turbo kit sone may ask.. Check this out :)

    Seems its now common knowledge that cylinder 5 (and 2, to a lesser extent) is a problem for several people out there. Running E60, 61% Meth w/CM10 nozzle, meowless downpipes, AMS IC, in 60 degree ambient temps, fresh walnut blasting, newer 1 step colder plugs (maybe 10k on them) gapped correctly.... Cylinder 5 almost always hits some 3-6 degree corrections, sometimes dropping to as low as 3.7 degrees from 13.5 (not all at once, but during the run), which tanks my avg. ignition.. things recover, avg. ignition drops to .9 ish, then it will hit again. Single pulls are less sensitive than multiple gear pulls, its far more likely to happen in a 2/3/4 pull vs. just a 2500rpm to 6000rpm 3rd gear pull, but it can happen in 3rd gear (much less though). Are there any values in BavTech logging that can reveal what's going on? There are hundreds of values to log if you look. - Is it EGT related? - Knock values? - AFR (I've seen bank 2 get .1-.3 points leaner preceeding a timing event) - ??? It's obvious that timing is being pulled.. but perhaps knowing why its being pulled is a good first step to fixing it? Do we have single turbos setups hitting cylinder 5 timing problems too?

    Is there any way to make this horrible new style go away? For some reason you have the site set to a column in the middle of the monitor, not using a 20% margin on either side of the page. It's horrrendous to read or look at. Help.

    Hey guys, Was able to get Ando's car back on the dyno to test out the new 1.00 AR exhaust housing. Mods are a JB4, VM top mount turbo kit, E40, meth, and all the bolt ons. The result was an impressive ~30whp gain from his .84 AR housing with improved spool. Looks like the COMP 6465 1.00 twin scroll is good for a nice spooling 700whp. Even on automatics. I also plotted it out against Payam's manual trans 335i running basically the same turbo kit, tuning, and mods, and you can see what an improvement the longer MT gearing makes on spool and power under the curve -- on the dyno. In the real world though advantage automatic. We'll find out for sure when the two of them race at Shift Sector in a month.

    Was clicking around instagram using N54 hashtag search and I cam across some interesting stuff. The instagram account of the Super RB tester posted some pictures of them, confirms they are not our Stage 2+, 2 days ago someone asked him how they performed. He directly stated, "Very Disappointing, decreased power, and increased lag. This was a guy running the normal RB's, so that means, the Super RB's are performing worse than normal RB's, with increased lag. Looks like it might be back to drawing board for ole RB. I usually would never bother to even post stuff like this, but when Rob went on E90, posted bold face lies about our products, and sent Shiv to take photos, was just the last straw, I have no problem exposing him for the hack you are now.

    This is a dyno of new RBs. The regular old version that have been balanced to 0.2 grams throughout the RPM range. OEM tolerance is 1.5 grams, High performance tolerance is 0.5 grams. These should be able to take a big beating These turbos also have the Thrust Upgrade. This Mustang dyno supposedly reads very low and most are not happy. After the first pull the guy asked me is this right? I said what? He said the dyno it seems very high 475 535. (all pulls in 4th gear. 1st pull 475 535 2nd 472 531 3rd 474 532 the Cobb stg2 aggressive 351 395.) I said I was hoping for 500 he then said this thing is a beast 470s on this thing is an animal. Temperature out was 78 and muggy so was hoping for better conditions. 475 535 was the highest run even though it is not on the sheet, he put my first ever Cobb stg 2 aggressive on there for comparison to now. Its impressive to say the least. I will be at the track Thursday night to see what she can do the 1/4 in. Ok to Terry first thank you for all your help this is a BMS flash that has some tweaks from Ken AKA Wedge, we had to get torque down to allow shifts from 4th to 5th and get fueling scale up for the map. Wedge thank you very much. 4th gear pulls RACE_AT: For use with E85, Methanol Injection, and/or Race gas mixtures Ken Wedge made some adjustments to the above map for fueling and torque issues where it would not shift from 4th-5th at times due to to much torque. 2007 E90 AT JB4 G5 Back end flash Ken Wedge Tweaked FBO HFS Meth kit RB turbos E85/93 E40 blend

    Hello, This is one of my first threads over here at BimmerBoost. I had been visiting tacopost but I have been frequenting this forum more and more. I hope you all find this of value. I would like to post my review of the El Cholo taco solution for proper satisfaction of human hunger. I have previously eaten many tacos outfitted with other ingredients and I was never close to satisfied. It just didn't feel like the tacos I know and love. There's this taco place I'm not affiliated with AT ALL called El Cholo that just has awesome tacos. Seriously, they are great! They also have Taco Tuesday with $2 taco deals and margarita deals that you wouldn't believe. They also treat me well and look at these tacos: The facility is pretty nice too: They even have enchiladas if you don't want tacos! I'm just a taco enthusiast trying to share my tacos enthusiasm with fellow taco enthusiasts. Please pay no attention to my e-mail address being sticky@elcholo.com. I hope you all have some yummy yummy tacos!

    One of our Billet Stage 2 customers took his 135 to track and laid down a solid pass that will only get better with practice. 11.6 at 120MPH. Looking forward to you getting your 60 ft time down and dropping that ET! This car was tuned by PTF/Motiv using the Cobb AP. You can head over to the motiv site for more info.

    We are happy to announce BMW finally got its act together, and delivered us two brand new M3/4 turbochargers yesterday. We wasted no time in getting them apart and seeing exactly what they have going on... What we found was a couple of turbochargers with a LOT of room for improvement, we will not be releasing any details on the turbos, wheel sizes, etc. As we are one of the first, if not the first tackling a turbo upgrade for these cars. But we can tell you, these will benefit greatly from some changes, they are not MHI turbos, and will be a little more challenging to upgrade then the N54. We will be building one set to test, the most obvious choice was Terry@BMS but he wants to keep his car stock for CARB testing, so we are looking for someone who is willing to upgrade to the JB, and work closely with Terry to get the car tuned. Someone local to him would be even better. This upgrade will be 100% INVISIBLE, the dealership will NOT be able to tell anything has been done to the turbos, everything will remain perfectly stock looking from the outside. The car will also drive normally as if stock turbos were in place when not tuned. This ensures no loss of warranty. If you are interested, please contact us at Sales@vargasturbo.com and we can discuss details. We are excited to be are the forefront of the new M series development. I attached a few pictures of the turbos. They flew United Airlines directly from Germany to SFO to come hang out with us, our dealer told us we were earmarked for the first set coming out of the factory....:D

    Motiv Motorsport posted a dyno overlay that provides perspective on the difference between two of their N54 single turbo kits and also the impact of their port injection fueling system. The 750 kit in the graph below is using E50 ethanol without the port injection fuel system. The Motiv 900 N54 single turbo kit is using the port injection supplemental fuel system combined with E48 ethanol. The difference between the two is substantial and the supplemental fuel is obviously necessary to hit the figures. Motiv 750: 705 wheel horsepower 680 lb-ft of wheel torque Motiv 900 with supplemental port fuel injection: 829 wheel horsepower 781 lb-ft of wheel torque This overlay is certainly interesting to see as we already saw the record setting Motiv 900 dynograph which touched off a spirited discussion in the BimmerBoost forums. A video has since been added which is below. The automatic transmission is obviously not capable (yet) of reliably handling any of these figures but solutions are being worked on.

    Nice race from our Russian friends here pitting the new breed of German twin turbo V8's up against each other. On the BMW side we have an F13 M6 with a Stage 2 tune from PP-Performance. The CLS63 AMG M157 is tuned by someone who rebrands other tuners tunes. Yes, for some unknown reason MHP still exists. The last time we heard the name they were selling Weistec tunes as their own. From what we have heard first hand, Weistec has distanced themselves from MHP. This 'tune' could be anything considering how MHP and Andrew Cluck have been passed around from tuner to tuner as if he was a drunk sorority girl at a frat party. Well, let's focus on how the cars do instead of how diseases get spread. There are three runs and in the first the CLS63 gets a nice jump. The M6 is able to reel it in and looks like it is starting to pull only for the CLS63 to let off due to traffic. The second run offers a more even start and the M6 again starts to pull. By 167 miles per hour it looks like the M6 has a good 5+ car lengths and is continuing to pull, impressive. The third run is the best of the bunch as the cars have the most even start. The M6 again pulls up top and continues to pull by 167+ miles per hour. In a roll on race like this the M6 has a couple advantages on the CLS63. To begin with, it is lighter by roughly 250 pounds. Additionally, the DCT transmission in the M6 shifts faster. Without seeing a dyno from each car it is difficult to exactly state how these factors affect the race but the result is the M6 pulling decisively on the runs.

    I wanted to put these turbos to a boost test, here is a 29-30 psi across the board pull, I popped a small boost reference hose to the gauge first pull, which tees to AEM map sensor so it shows lower boost after the shift, but its only because the map wasn't seeing full boost as the hose to the gauge popped off. If anyone had any questions on can stage 2+ hold a LOT of boost to redline, they can, and they can do it pretty easily. You take a BP hit as you see its at around 66psi, just slightly over 2:1. Timing for this boost level is pretty damn solid too, holds 10 degrees to redline, after the shift holds 8-9 all the way up. I will take this all day as well. I fixed the hose and you can see on the next run its showing 30 psi in 4th as well as it was getting the full boost signal. Notice how manageable EGT's are even at these boost, and timing levels, the car is pretty happy here. These can actually hold more boost if I want, but 28 tapering to 25 psi seems to be a good curve for BP, turbo longevity, etc, and where I will prob run them daily. Please keep in mind, the less boost you can run to get to your power goals, the longer your turbos will last. http://www.datazap.me/u/vargasturbot...3-256&mark=202

    Let's not spoil the winner just yet. You probably already saw the contenders from MotorTrend's World's Greatest Drag Race 4. MotorTrend takes the same vehicles from their driver's car competition and drag races them as well which is fine of course although the best driver's car likely is not the best drag racing car. The list of cars in the competition is the Alfa Romeo 4C, BMW i8, BMW M4, Chevrolet Camaro Z/28, Ford Fiesta ST, Jaguar F-Type R Coupe, Nissan GT-R Nismo, Porsche 911 Turbo S, Subaru STI, and Volkswagen GTI. These cars run a spread from $25,000 to close to $200,00.00. It is nice that there is something here as representation that can fit almost everyone's pocketbook but the performance spread is pretty large. It would be more useful to compare more cars of the same class than picking a couple from the lower end and a couple from the higher end. No Mustang? No Challenger Hellcat? No Viper? No Huracan? No GT3? No AMG? Come on guys, what is this? Here are the results in the order of how the cars finished from worst to first based on driving impressions (not just the raw laptime). Randy Pobst is again doing the driving at Laguna Seca. 10. Volkswagen Golf GTI 9. Jaguar F-Type R Coupe 8. BMW i8 7. Subaru WRX STI 6. Ford Fiesta ST 5. BMW M4 4. Nissan GT-R Nismo 3. Porsche 911 Turbo S 2. Alfa Romeo 4C 1. Chevrolet Camaro Z/28 If you were to order the cars in order of laptimes, the result would be: 10. Ford Fiesta ST - 1:51.25 9. Volkswagen GTI - 1:50.11 8. Subaru WRX STI - 1:47.16 7. BMW i8 - 1:44.29 6. Alfa Romeo 4C - 1:43.78 5. Jaguar F-Type Coupe R - 1:42.01 4. BMW M4 - 1:39.69 3. Chevrolet Camaro Z/28 - 1:37.82 2. Porsche 911 Turbo S - 1:35.62 1. Nissan GTR Nismo - 1:35.51 The Camaro Z/28 takes the title as the best driver's car and from this group. You have a 7.0 liter LS7 V8 revving to 7000 rpm offering glorious response under the hood, a manual transmission, huge 305mm wide tires at all four corners, and a car built around cornering and not just horsepower or acceleration. It is the car you would want to drive on an empty canyon road and the most rewarding of the group. It is the best driver's car. Source

    Finally some dyno results at the wheels for the new Dinan Dinantronics piggyback tune for the F80 M3 and F82 M4. Dinan announced this tune last month at a price point of $2499. Dinan's claimed figures are that horsepower rises from 425 to 516 at the crank. Dinan does hit 516 horsepower here but they do not exactly hit a gain of 91 crank horsepower. If that is confusing to you here is the explanation. The M3/M4 to begin with do not have an output for 425 horsepower. As the baseline shows, the car has roughly ~420 horsepower at the wheels in stock form putting it around 500 crank horsepower to begin with based on the classic Dynojet 15% drivetrain loss rule. Now, on the Dynojet peak horsepower with the Dinan tune rises by roughly 20 horsepower at the wheels. That puts the car over 516 horsepower at the crank using traditional driveline loss standards but it is not a gain of 91 crank horsepower. This is the problem with Dinan using crank figures these days instead of wheel output figures which provide a much more accurate picture. Additionally, dynocharts such as the ones you see below would likely not be favorable to Dinan. The horsepower delta is not what Dinan claims but the peak horsepower is what Dinan claims. The torque gains are greater though with close to a peak 50 lb-ft increase at the wheels. Dinan claims peak torque rises by 83 lb-ft at the crank so he is in the right range when looking at the torque. This Dynojet is having some issues so there are some data drops in the 5000 to 5500 rpm range but we still get an idea of what the tune is doing. Unfortunately, we do not have an air/fuel readout to verify Dinan's claims about superior control in this area. Does the Dinan tune add horsepower and torque? Yes. Is it very mild? Yes. Is it worth the money? Well, someone thought it was.

    The only option for turbochargers for the E9X M3 S65 V8 that is proven to be successfully running is from Gintani. Could they perhaps now have some competition in this area? Not exactly but it looks like Crzy Engineering is trying to create a rear mount turbo setup for the E9X M3. Rear mounted turbos solve a lot of packaging problems and make fitment much easier. They create their own set of problems though as your car should not have more plumbing than your house. The response and spool will not match turbos next to the motor with a well designed manifold. Regardless, Crzy Engineering is trying the rear mount approach using a pair of oilless 6065 Comp Turbo turbochargers. Who is tuning this setup? Good question. Is it even running? Good question. What does the power curve look like? Good question. Is this even worth the effort? Well, you see the pattern here. This may be a cost effective solution depending on the price but like most rear mount turbo setups there likely are better options out there. It is nice to see a another approach taken of course.

    Port injection in conjunction with direct injection on the N54? Yep, it is here and it is working well. How well you ask? How about 705 horsepower to the wheels and 680 lb-ft of torque to the wheels on an ethanol blend without any methanol injection necessary? Yes, that makes for an N54 horsepower record without any methanol. Additionally, it also means that supplemental port injection is another fueling solution for the N54. It is going to be interesting to see how the port injection setups and upgraded direct injection setups flesh out in the coming year. Regardless, N54 owners have fueling options to choose from now which is something that could not be said not too long ago.

    Hello, This is one of my first threads over here at BimmerBoost. I had been visiting e90post but I have been frequenting this forum more and more. I hope you all find this of value. I would like to post my review of the Markert Motor Works solution for a proper clutch type limited slip differential for the E9X cars and E8X 135 cars. I have previously driven many applications outfitted with the other gear type differentials and I was never close to satisfied. It just didnt feel like the earlier BMWs I know and love. Afterall, it was the E30s and E36s that got me into this rodeo. I was thinking, why cant my e90 have a similar feel? I thought it was because it was a turbo car, and that I needed a V10 to solve my woes. The lock up was never smooth coming out of corners or a nice slip angle, and they were always seemingly very noisy compared to a proper clutch type diff. Boy was I wrong about turbo vs NA! Friday came around and I knew I would be having my new differential assembly installed that evening. I was very excited. Low and behold, I had a friend drop by with an identical car to mine (2010 LCI sedan, alpine on black 6 speed). He has a wavetrac in his car so I drove it so that I would have a comparison. After the test drive, and I mean test drive ;) I brought the car back and I still was not that thrilled. It was making me nervous about my car and how it would feel after the diff swap. Come 6 o'clock, I get my car back with the new differential installed. I pulled out of the parking lot, and I immediately screamed "I love my car again!!!" (while completely sideways coming out of it smoothly and precisely as a professional driver). I immediately thought, "now no longer need the S85" (although the want is still there). I could not believe the transformation. It was incredible! :happyanim: I then began to call everyone I know with a later model BMW to tell them the news. This thing is BRILLIANT! You MUST get one! So far I have two other buddies get them (both members so I am sure they will chime in). One in a 335i and one in a 135i. Both FBO. Pics!: Install: Obligatory burnout: Lastly: Funny Meme a friend made due to my extreme happiness: But all shenanigans aside (even when not driving like a hoon) you can notice the traction control not having to work as hard. Launches from a stop are now much smoother and thus quicker out of the hole. Exiting corners is the biggest plus, since the lock up is progressive versus On/Off, it is extremely smooth. No more of that craziness coming out of turns (which in my opinion was extremely dangerous). Make sure you all check these things out! Talk to yall soon :thumsup:

    I'm going to buy a new car next year and it's going to be a domestic because fuck BMW and I want to expand the network reach. I like the Hellcat. I like the Stingray. Really I want the Z06 but since turbos on the M3 are going to take that portion of the down payment away I don't think I can swing both a Z06 and another forced induction build. So, the Hellcat and Stingray are both cheaper. Which one? Hellcat is already supercharged and going to have a big following. The Vette is sportier of course and can also be modified just not quite as easily. I already have a car for big power so considering this is more about driving enjoyment I'm leaning toward the Vette.
