    Get used to seeing 10 second N54's. Frankly, it's about time. Recently two 135i's broke into the 10's each with upgraded stock frame turbos. Why this run is significant is that it is a 10 second upgraded stock frame run in a BMW E90 335i. The E90 3-Series is heavier than the E82 1-Series. How much heavier? Roughly 300 pounds with the driver. A significant amount yet the car still cracked the 10 second barrier. Here is the mod list: RB Turbos TFT Inlets JB4 G5/MHD FuelIt stg 2 LPFP HFS-4 meth kit E60 E85 DSS Axles AR DPs Cpe FMIC Tial BOV NT05R's The picture you see in the beginning of this post if of the stealth RB and RB inlets and not the setup on the car that broke into the 10's which is the 'classic' RB stock frame turbo upgrade. Expect even more out of the car when the new turbos go on. Also, expect more 10 second N54's which should now be common. We also have a bit of a back and forth vendor war going in the stock frame N54 turbo upgrade game which is good for all of us. It should push the limits of what they can achieve. A good old fashioned shootout is getting the platform quicker and faster times on the strip. Congratulation to @newb335guy and more details in his words below:

    The Cadillac ATS-V LF4 3.6 liter twin turbo direct injected V6 responds very well to tuning. Its tune only results put it well over 500 wheel horsepower. This ATS-V in the video features the Fasterproms ECU tune along with catless downpipes. That is a recipe for 558 horsepower to the wheels. Tune only S55 motors in the F80 M3 and F82 M4 show great gains but not nearly enough to beat an ATS-V on the highway with a tune and downpipes. Keep in mind BMS shows gains with a basic Stage I S55 tune in the ~480 whp range. Things vary depending on the JB4 tuning map and the fuel quality. Despite the F80 M3 being lighter than the ATS-V and having the quicker shifting DCT transmission it can not match the ATS-V's raw grunt on the highway when it has a tune plus catless downpipes. This M3 would need catless downpipes itself, race gas, and a more aggressive map/tune for this race. Despite the obvious power and torque disparity the M3 hangs in well until the upper gears where the ATS-V shows its muscle. It would also be interesting to see how an a 8-speed automatic ATS-V would fare. This is of course just the beginning of the ATS-V and M3 rivalry. With the C63 in the mix it will be fun to watch this battle unfold with the cars in various states of tune.

    Port fuel injection is becoming increasingly important for the BMW N54 3.0 liter direct injected twin turbo platform. Keywords in the previous sentence being 'direct injected' as supplemental port fuel injection is helping fuel these big turbo builds that need fuel. The JB4 tuning platform is arguably the most employed on N54's on BimmerBoost and port fuel control injection integrated with the JB4 tune is definitely something to watch. Further details directly from Burger Tuning below. Terry@BMS: Been throwing around some PI ideas with Steve and we've come up with a workable mechanism for integrating port injection control in to the JB4 using the existing AIC6 hardware. This will let us get started on the JB4 port injection control and mapping now without having to wait for our PI box to be fully ready/tested. It won't have all of the cool port injection specific features we have planned with the new PI box but even like this will be superior to any of the other port injection control mechanisms currently out. Who knows maybe this will work so well most of you won't even want to bother with swapping the AIC6 for our box. The basic premise is that we've changed the AIC6 boost reference input from the TMAP sensor to a JB4 generated output. The JB4 will pass a high frequency PWM signal in to the AIC6 that represents the desired duty cycle. To that end we've created a special AIC6 map that has a consistent duty cycle for each voltage input and engine speed. We can use up to 50 columns for this so the resolution is pretty good. It winds up as a 16x50 table with each column representing an additional ~2% duty cycle. Among the first things we want to develop with the JB4 PI integration is an autotuning algorithm that self tunes the PI curve on the fly using the high fuel pressure set point as a control variable. The JB4 will alter the PI mapping such that high fuel pressure never drops below a certain curve. Ensuring we're pushing as much of the fuel through the factory system as we safely can and then adding in the minimum PI volume needed for the instantaneous conditions. It's a fairly ambitious project but will be a real game changer in terms of PI integration and ease of tuning. After we've spent some time on that we'll also integrate it in with the E85 flex fuel kit Fuel-IT offers so the JB4 also considers the ethanol content automatically for PI mapping. I'll update everyone as more progress is made. Tested the JB4 to AIC6 comms out on the bench and its actually all working really smoothly. The AIC6 accepts in the JB4 PWM signal and converts it to an internal voltage without need of any extra external discrete components. This will make wiring much easier at home. You'll just remove the green wire from spot #10 in the JB4 harness and relocate it to spot #9 on the BMS DATA cable using a DSUB pin. I was able to get a basic map done and tested in car before I head out for SEMA and it all worked as planned. Logging independently on the R4 software shows its receiving the JB4 command and converting it as planned. JB4 Fuel Enrichment now represents the port injection duty cycle.

    This car belongs to BimmerBoost vendor @fastgti69 who of course is using his own VM (Ventura Motorsports) N54 single turbocharger kit on his 6-speed manual E90 335i. He recently got it out on the dyno with Terry of Burger Motorsports to do some fine tuning. The result is over 800 wheel horsepower and 834 horsepower and 720 lb-ft of torque at the wheels to be exact. The thing is, they are not done here. There is more in this car. The N54 horsepower record still stands at 861 rear wheel horsepower but as we have more N54's pushing deep into the 800's along with further tuning revisions for these high horsepower cars we should start seeing records fall. Further details below from @Terry@BMS: Hey guys, Spent some time on the dyno today with Payam@VM's car. Main purpose of testing was to evaluate the new JB4 single turbo O2 sensor calibration and JB4 port injection control. In doing that it appears we also upped the official bar a bit for single turbo N54 power. Notes: 1) This big turbo really sings at 35psi. It's starting to get to the point that we need to add 4bar and 5bar MAP sensor support to the JB4. It's on my radar. 2) Car has a major issue dropping timing in cyl4. We have no idea why. 3) The JB4 o2 sensor control is working very well. It's amazing how lean we were running previously without really giving it much thought. The second dyno file is a comparison to his testing a couple months ago. AFR was creeping up to the mid 13s. If you're running a single turbo and not using the latest JB4 o2 sensor control firmware, your AFR is much leaner than you think it is. 4) The JB4 port injection control is working perfectly as well. It's convenient being able to datalog and change it from the same JB4 interface and it's nice that it finally self corrects for low fuel pressure. Much more planned for this. 5) Given the AFRs are accurate now we're using *a lot* more fuel than we did previously. Maintaining low pressure on E80 (as read via JB4 flex fuel sensor) has become an issue again. Been funneling data to Fuel-IT who has some new stuff in the works. 6) I heart JB4 anti-lag.

    Congratulations to BimmerBoost member sA x sKy who put down some eye opening numbers with his DCT F82 BMW M4. He managed to crack the 700 wheel horsepower barrier with his BMS JB4 tuned car which is upgraded with the Pure Turbos Stage 2 S55 turbochargers. @sA x sKy has upgraded Dodson clutches which is the way to go for BMW DCT upgrades. Noting this is a DCT car is important as it is currently the highest horsepower DCT F80 M3 or F82 M4. The 708 wheel horsepower Pure Turbos Stage 2 upgraded F82 M4 we saw a few months back has a manual transmission. Great numbers here and further details from @sA x sKy below. We also look forward to seeing more timeslips from this car. So two different people told me to make a new thread for this.. so I hope you don't mind Sticky :D So my car was finally fixed today for a timing chain issue (second time..) and we wasted NO TIME whatsoever going to the dyno since street tuning was out of the question b/c of the weather outside. Literally we retimed the engine, put on the carbon fiber brace/strut brace on, turned on the car for 10 seconds.. and said fuck it let's go dyno. With the help of Jesse@PURE and Terry@BMS, I did 5 runs. 640whp, 658 whp, 660 who, 679 whp, and 704 whp! Had I had time for one more run I could have taken the dyno record but I'm content with this for now. We were building boost slowly up first but because the 5th run was the final run of the day, we said fuck it and went straight to an 85 meth additive for the 704! NO CODES. NO DTM. NO LIMP. The car ran amazing those 5 runs. 100% meth with 5 gallons of MS109 Thanks to Petrolwerks for building this awesome machine! And thank you Jesse@PURE, Jason@TPG, Terry@BMS, Mo@ACM, and T0ny32 for all the help along the way. Seriously, this project wouldn't have been possible had it not been for the combined efforts. Atco track rental is on Wednesday to hopefully break another record! I ran a 11.17@126 (maybe 127 I don't remember) with M/T ET Streets II. I have upgraded Driveshaft Shop axles this time so not worried about going full boost on this thing off the line. Objective is a 10.5@XXX. This is the highest whp F8X DCT in the world as of right now, and second highest whp overall. Can't thank Jesse@PURE and Terry@BMS enough for the personal touch for this car.

    Weistec was not kidding around regarding their M177/M178 turbo upgrade development when they said they started last year. Teaser photos were shared early this year and Weistec quietly and diligently worked on the upgrade. Well, here it is and they managed to deliver it before the end of 2015. That is impressive considering most tuners tend to deliver upgrades late (if at all), not early, and rarely on time. The Weistec W.3 turbo upgrade takes the M178 in the AMG GT S to 650 wheel horsepower and 557 lb-ft of wheel torque on 91 octane pump gas. It is important to note these are pump gas figures as there is obviously more in the turbos. Keep in mind this is also on the stock transmission. The car also features Weistec's supplemental bolt on modifications. Now this turbo upgrade system is employed on the M178 in the AMG GT S and Weistec's car at SEMA earlier this month already had this turbo upgrade on it. This upgrade will of course also be available for the M177 in the W205 C63 AMG and S models. As the transmission is an MCT and not DCT it will be interesting to see if the C63 makes more torque with this upgrade. The power curve features spool like the stock turbos just with more torque everywhere. The upgrade is even a bolt on affair maintaining stock like appearance. AMG GT or C63 sleeper anyone? At $12,499.99 it certainly is not cheap but considering this is an application that has undergone significant testing and is essentially OEM level in development using the factory oil and coolant lines it is well worth the money. We can not wait to see what it does on the track and how much further Weistec will push the M178. Transmission upgrades are no doubt up next to handle even more torque on race gas. KEY FEATURES: Up to 650 Wheel Horsepower with supporting upgrades 5 Axis CNC Machined High RPM Balanced for perfection operation Substantial gains in peak HP and top end Rev Limit for AMG GT / GTS increased to 7500 RPM Stock Appearance when installed 100% Bolt on installation ECU Calibration included All necessary hardware and gaskets are included ** Coming Soon for W205 C63 and C63S
