    :boxingOk so after months of repeated advancements and new benchmarks for the N54, today, the California based tuners and turbo manufactures, will battle it out for the bragging rights. I don't know if I am the only jaded BB forum member here that has been paralyzed by the recent barrage of turbo and fueling developments for the n54 platform, wading through post after post, marveling at the turbo and fueling developments, even placing a deposit along the way, but ultimately having to wait. Suspiciously, the reason I think we've been made to wait, however frustrating, is a pretty good one. Our beloved tuners and turbo manufacturers have been careful with their updates and releases, operating in an almost genius CIA like fashion, giving us just enough information to create desire in their revolutionary-to-the-platform product over a competitor's products, with a masterful and deliberate delaying in the actual product release. Why you might ask? To create awareness and interest about their products, but ultimately, to retain a competitive advantage over the competition, who may have a superior turbo but no fueling, or fueling but no turbo, hardware but no tuning, all of the above, but no transmission. LMAO After months of conjecture and speculation, it's finally SHOWTIME! Best of luck to all the folks and companies competing that have done so much for the platform and the community. Wish I could be there. As far as the N54 Camp is concerned, What are the predictions? Which tuner, and which manufacture will be on top when the dust settles, will it be a singe or a twin turbo setup car? Will it be running port fuel injection or a dual HPFP? I guess we will know soon enough!

    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 :)

    Despite our best efforts to get our shop car running properly in time for the event we decided not to run the car at all this past weekend. The #2 cylinder is leaking down over 25% and we will be putting another stock motor in shortly to continue development so we just cruised down to Coalinga to spectate. Here are some photos from the event. Hope you all have a great week! It will be a very busy and exciting one for us as we continue to assemble / ship the Stage 2+ N54 turbos and are awaiting testing of the world's first S55 turbo upgrade :music-rockout:.

    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.

    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 I hope you all have some yummy yummy tacos!

    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

    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.

    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.

    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.

    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 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

    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.

    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:

    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.

    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.

    Great drag racing action here! The E63 we all know well on this network as it belongs to Benzboost member Vasily1. Most recently we saw it in action against an Audi RS7 with upgraded turbos. The 850 horsepower quoted output on the E63 is accurate as it has upgraded turbos courtesy of Renntech. Run 1 E63 vs. M6: The first race has the E63 AMG S 4Matic going up against an F13 M6 with a PP-Performance Stage 2 tune. The output is claimed to be 720 horsepower which we have no way of verifying but it certainly is possible with the right supporting mods. The M6 puts up a good fight but the E63 is quicker to each marker and traps higher at each marker. At the 1/4 mile the E63 is pulling harder with a 132.52 trap speed to the M6 128.70. At the kilometer marker the E63 hits a 19.594 @ 172.20 to the M6 20.748 @ 166.43 miles per hour. Definitely a good run between these two. Run 2 E63 vs. TT-RS: The next race features our friend @Vasily1 with his E63 against a Revo Technik Stage III modified TT-RS said to be putting out 530 horsepower. We have seen this TT-RS in action before and it sure looks like it is a lot stronger than the claimed 530 horsepower. This is another good race and the E63 is able to edge out the TT-RS. It also is definitely pulling harder up top than the TT-RS. That said, the two cars are only 3/10's apart at the 1/4 mile marker. The E63 1/4 mile trap speed is 132.43 MPH to the TT-RS 130.35 MPH. The E63 runs through the standing kilometer in 19.719 @ 170.36 MPH to the TT-RS 20.465 @ 161.07 MPH. The top end is all E63 but that is one impressive TT-RS. Runs 3 E63 vs. ZR1: The ZR1 is said to have 850 horsepower but without a dyno we are just taking it as an estimate. A bolt on ZR1 can have this crank output depending on the modifications. The ZR1 also obviously is much lighter than the 4Matic E63 AMG S with roughly a thousand pound difference between the cars. This is yet another great run and the E63 again comes out on top thanks to its top end power. The ZR1 gets a decent launch but it just does not have enough to pull the E63 up top. The ZR1 has the slightly higher 1/4 mile trap speed but by the half mile the E63 is pulling harder and at the kilometer marker it has a 5.8 mile per hour advantage. Those turbos have some serious top end punch. The E63 ends up running a 19.795 @ 171.41 miles per hour in the kilometer (showing remarkable consistency) to the ZR1 20.946 @ 165.57 miles per hour. Great races and great stuff from this @Vasily1's E63 yet again:

    I'm having a little trouble nailing down the image below. I can follow the diagram for the most part but I wanted to confirm what needs to be adjusted when my actual load is getting too close / exceeding requested load. I know I could lower WGDC but I'm looking to simply raise the "Load Requested" without lowering boost, after all, the goal is to make more power. Then as a result, my timing is being limited, with no corrections I'm hovering around 0 deg. until boost tapers off. Seems the DME prefers to first use boost to make power then when it can't supply enough to hit the target load it'll allow for added timing up to the limits of the table. I did research this and it seems people were having luck by reducing the last row in the load to torque limit table, I believe raising the torque ceiling (AT) and modeled torque limit 1-2 tables should effectively do the same thing without tricking the vehicle into thinking it's making less power than it really is. (assuming I'm reading the above diagram correctly) What I don't want to do is make more boost as a result. Alternatively, again if I'm reading the diagram correctly, reducing load limit factor and boost limit multiplier should give me a bigger gap between actual and requested load? I have a log showing exactly what I'm talking about. I had a little wheel spin in the beginning of the log which is why the RPMs look rough. 3500-4000 RPM is what I'm really focused on.

    The Good: Long story short RBs are pretty beastly I am trapping 6-8 mph faster than I use to at the track. Comparing Apples to Apples my buddy in his JB4 FBO back end flash car was trapping 116-117 best a 118 at 11.8. A FBO 135 Jake Cobb Pro Tuned car was only doing 112-114 with his best being a 12.1 at 115. So some perspective on the night and an Apples to Apples comparison before I get the ones chiming in I trap 123 on stockers. I doubt that will be done where I run at and this is how the BMW's run here including myself and others. My time slips from last night vs my Last run with my stockers The Bad: I could not launch hard in 2nd due to torque shutting down power then allowing it to shift into 3rd then I would be out like a rocket ship. And yes I have an Alpina Flash Wedge suggested the 2011 Alpina Flash so who knows. Its still a work in progress to figure out how to get all this power to work together while doing a 1/4 mile run. The car is super fast in rolls and great after 2nd has shifted during launches. I will need to play with limiting boost in 2nd for optimal launches without hitting a torque shut down. If I can do that this car is easily 11.1-11.3 car its just a beast but she has to be harnessed. I have GO Pro vids but I need to edit them down so they do not take hours to load on youtube. In the race against my buddies 335 you cans see how 2nd gear falls flat then it shifts catches boost in 3rd and I am out. The UGLY: Another buddy in his E92 stick on his very first pass he tried to launch and broke an axle, UGLY. Anyone have pointers for loading GoPro vids to Youtube?
