    I've been away from the computer for a bit enjoying the olympics and was pleasantly surprised to see Tony reaching out with an e-mail in my inbox. I'll skip the particulars but I think there is a possibility of mending fences. Ultimately, the decision is based on what is best for the forum and its members. That means you guys. Do I want all products available here? Yes. I do. I want you to have the ability to choose from a bevvy of tuning products with great support and advertising available. I'm in this to have the best forum and site for you guys. I'm not in this to hug every vendor and sing kumbaya with them but I can certainly be respectful. I can be a professional and so can the vendors here. There certainly have been ups and downs. I'm not just making a unilateral decision but informing the community as it can be a delicate ecosystem and I prefer to inform you of what is going on as after all, the users make the forum. I reached out to @Terry@BMS about this issue and resolving it so everyone is satisfied. Terry is doing business with VTT and some interesting things which I think you would all want to see, right? Let's see what BimmerBoost users have to say and if we can be above a mob mentality and forgive. I'm not going to say I am without blame.

    Well, the new BMW M5 is the raw muscle champion out of the newest sport sedan crop. It will beat all of it rivals in a drag race and do so rather easily. It certainly helps that BMW has the displacement advantage on everyone except for Cadillac and Jaguar. The thing about Cadillac and Jaguar is that they are not running turbocharged powerplants. The previous generation F10 M5 was heavily sandbagged in output. One can only imagine what the real output of the F90 twin turbo S63B44T4 V8 is. If we were to guess, it's making over 600 horsepower to all four wheels stock. Yes, more power at the wheels than it is rated at the crank. There is no other way to explain it hitting 129 miles per hour of trap speed through the 1/4 mile even if it is a magazine time. The 10.9 elapsed time should be easily replicated on the dragstrip by owners. All wheel + automatic = easy launches. The new M5 is not only the quickest and fastest car in its class it is also the lightest. Well, at 4288 pounds it is the lightest all wheel drive sedan. The Cadillac CTS-V is the overall lightest in the class at 4108 pounds. Congratulations BMW. You built the best 4-door dragster in the world.

    335MAD started a thread N54 TARGET boost low in N54
    Hi all, I'm having trouble with my N54 335 and was hoping someone could help shed some light on my issue. Would be great if someone more knowledgeable could look through my logs? Basically under WOT the car hesitates and lacks power around 3500RPM - 4500RPM. No jolt, no codes, no lights. Feels lethargic and down on power. Resetting adaptations seems to help. I have attached logs (MHD stage 1&0) where you can see the boost TARGET is repeatedly low on many pulls when this problem occurs. Why the target is low beats me. Never had this problem before and it's always boosted fine. Boosts fine to target (even if 14psi target- rare but it should be that high) 78k KM, new HPFP, LP fuel sensor, VANOS solenoids cleaned, BMS OCC, DCI, vsrf cp, RB PCV valve, MHD. Plugs have 10k km on them, about to do valve cleaning, some older style 3&4 index injectors, some 9, unsure how old coils are. I have searched high and low to find a solution! Nothing seems to address low boost TARGET that I can tell. If I'm lucky and the target is high, it has no problem building boost to the set target. I wonder what inputs have an effect on DME boost target. STFT seems all over the place? And 15-16 on AFR? Lean?? Knocking? Thanks in advance for your help, these forums are such a wealth of information and absolutely love my new car!

    Budler Motorsports has a new car and it's going to be great They took the billet S38 motor from their record holding E30 and have gone mental with a full chassis pro mod They are still testing the combination but it did 8.8 on their first shakedown run and 7.49 on the second run The car will also be competing in the haltech import Vs domestic world cup 2018 if all goes well along with a few other south African cars

    Thanks a lot feminists. You have even managed to get your hideous tentacles into the pinnacle of motorsport to strangle to death an aspect fans love. Those fans are predominantly men so you can understand why Formula 1 would be a target for the modern day feminist. In our ever more so politically correct society attractive women 'cheerleading' at sporting events are apparently a no-no: Yeah, right. Super hot women around hundreds of millions of dollars of world class race cars in locales around the globe piloted at incredible speeds to determine a victor somehow doesn't appeal any longer. What should these women be replaced with? Perhaps some 300 pound blue haired feminist lecturing the audience on how race cars are racist because 'race' is right there in the name? What do the women who just lost their jobs think? Say what you want about Bernie Ecclestone, he wouldn't have caved to this absurdity. Source

    Hey guys, Had a chance to spend a little time on the dyno today with our development M4. Driven by Payam@BMS it's a 2015 manual trans with around 80k miles. Bone stock except for a JB4, BMS intake, and our development back end flash map loaded via MHD. JB4 is using latest v1.8.1 firmware with the higher speed data logging. Testing today was done on straight E85 so we could test the limits of the factory fuel system. Some quick notes: 1) The high pressure pump keeps up with straight E85 relatively well at this power level, but pressure starts to nose off around 6000rpm at max boost. 2) Low pressure held fine even under higher RPM higher fuel demand. 3) The factory turbos still run out of steam at higher RPM. Exhaust modifications might extend the usable range slightly. 4) We ran the tuning with relatively conservative ignition advance peaking around 9 degrees. A couple timing drops here and there but mostly due to the back to back runs and working the turbo beyond its efficiency range at higher rpm. I meant to try running higher advance at higher RPM where the turbos drop off, but didn't have time to test it today. Next time. 5) Just for kicks I did a run on existing additive map1 and map2 for comparison. With the BEF loaded we'll be reprogramming all the JB4 map options so you retain a similarly wide range of power delivery options at your fingertips. Lots more to come... Attached Images

    It was just a matter of time. We knew back when BimmerBoost member @allmotor_2000 went to the Pure Turbos Stage X S63TU turbo upgrade that his F10 M5 was a prime candidate to top the vaunted 1000 rwhp mark. Well, mission accomplished. How about 1008 rwhp? Mod list: Pure Spec X Turbo System Carbahn Autowerks built S63TU motor BMS custom JB4 and Meth DMETUNING backed flash Upgraded DCT DSS driveshaft and Axles Milestone reached and broken. This was hit with 34 psi of boost and slipping clutch discs. The stock rear section of the exhaust is also in place. Congratulations to all involved! Now how much further past 1000 whp will they go? The record holder is still BPC with their 1026 rwhp pull but the point is multiple F10 M5's are now topping 1000 to the wheels. Maybe 2018 is the year of the S63TU?

    Aus335iGuy started a thread DCT FTW in N54
    News just to hand Jayamona@motiv has managed to find and alter some of the tables in the N54 DME and essentially N54 DCTs will soon have launch control with user selectable launch RPMs. Other platforms on MHD as well (yes you poor deprived N55ers) It will be out before the north American summer i hope with other “goodies”. Next One particularly savvy tuner PureEvilN54 has divulged how to set the ignition tables in the DME to provide anti lag (this has been seen here before its just that hes shared it with others Another great development is that we now know that we can flash M3 GTS software to N54 DCTs. You need the GWS unit and some flashing and coding This means we can change shift severity on the fly because drivelogic works(you need the button) You lose launch control but you gain another thing and that is if you use the M3 ZB file you can also use any M3 final drive ratio. DCTs will soon be the fastest n54s...

    No shame here. The BMW M2 is simply nowhere near the level of the Audi RS3. Despite the BMW's N55B30T0 powerplant offering half a liter of displacement and an additional cylinder over the Audi's 2.5 TFSI it gets clobbered. We all know the M2 is neutered to keep it from stepping on the toes of its big brothers but the RS3 sedan is more than a match for anything BMW has in the lineup. Seriously, it is running 10.0 flat at over 140 miles per hour on the stock internals. Built motor F80 M3's or F82 M4's would have their hands full competing against that. Here is what the two cars in the video below bring to the table: 2017 BMW M2 ER Catless downpipe Wagner Evo Comp 2 Intercooler ER hot and cold chargepipes Dinan intake Dinan resonator delete and muffler Pure turbo inlet Fuel it LPFP Bootmod 3 Stage 2 OTS 2018 AUDI RS3 IROZ Motorsports Front mount intercooler IROZ Motorsports Downpipe + midpipes Custom Code stage 2 91 octane software Stock everything else. From a stop the M2 gets crushed. From a roll it is slightly closer but it still gets crushed. The bottomline is the RS3 is on another level with bolt ons let alone with turbo upgrades.

    Hey guys, I am happy to be back here on BimmerBoost to share new products, results, and answer technical questions -always a good idea to have a forum presence and that's what I'm here for. Let's jump right back into it. 2018 has quite a few VTT products being released, but here is a taste of what's coming in the N54 world: GC REBOOT Let's get started with the GC Reboot! We took our already potent GC line up, and did a ground-up redesign, getting rid of some things we didn't like and adding things we wanted to improve. Key Features of the GC 2.0 reboot are as follows: • 100% designed, and cast for VTT: this is not a partnership with any other company • All new castings with VTT logos front and center • D5S Ni resist material is used throughout the hot side. This includes Turbine housings as well as manifolds. • All-New Compressor housings with ribbed inlets to ensure a secure fit from inlet to housing. • Single piece V-band clamp connection from turbine housing to manifold sized to fit Tial Clamps. No more awkward two-piece clamps to install. • Our single biggest improvement is the casting of our proprietary turbine wheels in Garrett GT28 profile with a TD04HL shaft to fit the existing GC family bearing housing. Wheels are cast from Inconel 713L. This eliminates the industry-wide TD04HL 9 blade wheel failure problem while improving wheel Aero; better spool and more flow. • Same as before, both Full sized GC’s, and GC Lites will be available. • Rebooted pricing. With all these improvements the GC line up will cost less when released, NOT more. • ESTIMATED AVAILABILITY DATES o Late Q1 2018 with special intro pricing on website for GC’s and GClites ALUMINUM CHARGE PIPE Next up we have our new VTT Aluminum charge pipes. We have heard many stories of silicone charge pipe issues. While they work perfectly well when installed correctly, the number of install issues lead us to create more durable aluminum charge pipes that share the increased flow capability of the silicone units. Key Features of the VTT aluminum charge pipes are as follows: • High flow Y connection to merge both banks • No more melted outlets from install too close to the manifold • Available in factory V-band connections, and 1.5” hose connection to fit GC turbos • Available in 335LHD, 135/535/Z4 these will NOT fit RHD (sorry guys) • Hard powder coated black • ESTIMATED AVAILABILITY DATES o Q1 2018 (end) VTT SINGLE KIT Next, we have what most will see as a departure from the usual VTT philosophy, but we felt it was time to give the N54/N55 platform another option in the popular single turbo section. We still love twins but sometimes you just want a quick-spooling high flow single. We got you covered. :D Introducing the VTT Cast Manifold V-Band Twin Scroll Bottom Mount Single Turbo line up. Please note while we have been working on this for a while and have many parts cast, these are not expected to be released until late spring or summer 2018. Also, note the pictures are representative of our “blank” manifold casting. Our fabricator is adding O2 bungs, and EWG flanges for the N54, and EWG kits. The N55 kits using IWG turbos will use the blank manifold as no O2 bungs or EWG flanges are needed. Key Features of the VTT V-Band Bottom Mount Single Turbo Kits are as follows: • Industry-first true twin scroll bottom mount kit using V-BAND connection for ease of install • EWG and IWG kits will be available. IWG kits will use FACTORY boost control. No need for add-on boxes, or Mac Solenoids • Competitive pricing • Fitment for N54 and N55 (N55 details to be posted in N55 section soon!) • JB and DBB options will be available • Manifold cast from Ni-Resist D5S • GENUINE Garrett turbochargers used for DBB optioned kits • Ball Bearing Turbo choices for N54 will include: o Gen2 GTX3076R (600WHP) o Gen 2 GTX3582R(700WHP) o GTX3584RS(850WHP) (3076, 3582 available in IWG, or EWG. 3584RS EWG only) • Journal Bearing Turbo choices for the N54 will include o GTX3076 sized Journal bearing turbo with IWG control • ESTIMATED AVAILABILITY DATES o N54 EWG kits end of Q2 2018 o N54 IWG kits Q3 2018 VTT SHOP CAR PROGRESS Not really an announcement, just a little hint of some cool stuff we're doing. A couple teaser pics of the shop white car, which ran 172.9x in the 1/2 mile. When we did that (nearly a year ago) the car had GC's on her, was full weight and Tony was rowing the gears. Time to step it up a notch. Below is a pic of some serious turbos, double overdriven hpfp's, and enough instrumentation to keep getting the data we need to push limits. Personally I'm very excited about seeing this progress, and looking forward to keeping you guys posted on this one.

    Another day another N54 turbo upgrade with Chinese sourced housings. Introducing Kott Turbo Works which is based out of Illinois and offering various N54 turbo rebuilding and replacement services along with a turbo upgrade option. You may recall a rather interesting thread on BimmerBoost that highlighted a certain turbo vendor going to cheap Asian cast housings and the problems that came with that switch. Make no mistake, there is only one reason to go to China for housing production and that is to lower costs (upping profit margins), not improve quality. You can make the decision yourself as to what you want to run but it certainly seems those offering upgrades utilizing the factory housings are more reliable over the long term and higher quality. Kott calls their upgrade the KTB001: Hybrid TD03 turbochargers front and rear for BMW N54 engine with billet compressor wheel. 43.4mm inducer, 56mm exducer billet compressor wheel 41.2mm exducer 47mm inducer turbine wheel 44mm inlet inside diameter New high strength stainless steel wastegate bushings Vanadium alloy cast turbine housing 1000 Celsius rating Capable of producing 600+ horsepower with proper tune on E85 fuel 500 horsepower on 91 octane pump gas High performance journal and thrust bearings VSR balanced No core charge 1 year warranty $1400.00 This is the current state of the N54 market. To do a high end motor build and turbo setup with proper tuning will run more than what the cars cost these days. The market is flooded with kids who want a ton of horsepower for bargain bin prices. Many of whom just buy whatever is the cheapest whether it comes from a scammer or if it is low quality junk that cracks. You can also look at it as the N54 platform is a tuning value rather than as it experiencing a quality drain. The truth is probably somewhere in the middle.

    This is a battle we have all been waiting to see. The Audi RS7 4.0 TFSI V8 gets a ton of credit and deservedly so. There were those who mocked Audi for providing the smallest twin turbo V8 in last generation's mid-size sport sedan market yet Audi's potent mill proved to be the strongest tune only despite its displacement disadvantage. Amusingly, Mercedes-AMG went to a similar style V8 for the new W213 E63 yet it isn't as strong with a tune as the now old RS7. Obviously, the 4.0 TFSI is stout with RS7's running 10.2's in the 1/4 mile at 133+ which is the stock turbo record in the USA. The RS3 is already beating that. Easily. The little brother barely entered the market and is already kicking ass and taking names. Now what is interesting in the video here is you have an RS7 on upgraded Garrett turbochargers. You will notice there are not really any successful upgraded turbo RS7's running around and this RS7 is said to still be under development. The RS3 has a big turbo setup from Iroz on E85. What happens? The RS3 spanks it. The guy in the RS7 needs his eyes checked if he thinks that was close. Say what you want about having a V8 carrying 1000 less pounds makes a huge difference. So does that dual clutch transmission in the RS3. From a 35 mph roll it's ugly too. The RS3 runs away. Why haven't big turbo RS7's shown well? Who knows. Big turbo RS3's are already crushing them though and it's not likely to get any closer from here on out as 2.5 TFSI tuning accelerates.

    So here it is, i posted this on the other M forum but figured there are more boosted M cars here plus ill get better feedback I am hoping. (Still a noob to the boosted S65 world) I have a 2008 BMW M3 coupe. 6 speed, 85k miles. (original clutch still ). At 65k had BE BEARINGS done with ARP bolts (pic 1). At roughly 70k i had gotten a Gintani E85 tune (burble) along with Advanced Fuel Dynamics PROFLEX Commander installed (pic 2 of the install). Ran Great. Also threw on test pipes, under drive pulley but for some reason decided to keep it with the stock 2008 OEM intake and filter (legit too lazy to buy a new filter) and she threw down 384 on a dynojet. (pic 3 of baseline and fbo on e85) at 78k miles i decided i wanted more power so i went and bought a vf620 supercharger kit and got a BPM tune (pic 4). installed it, ran great... but i had forgotten to swap out spark plugs so within 3 days it started to blow spark out and dip down on power(pic 5 and 6). I waited roughly 2/3 months before finally getting new plugs (went with NGK Laser Iridium 95770 at a .22 gap pic 7). Was recommended to me by the shop i go to and works great (except on really cold days it struggles to start when filled with E85 but that was anticipated) Now she has new plugs (at 85k) and currently running great (so i think). Got it dynoed yeserday at a local dynojet (will be going back to my normal dynojet ive used in a week or so) and she put down some good numbers. Their AFR reader was reading all wack, might be my car, might be their reader, i dont know for sure(pic 8 showing ARF up to 18). So my way to illuminate the confusion will be to go to my old dyno and retry there since i know they have been consistent so far. I did dyno my car at my normal dynojet spot when i supercharged it to try and pinpoint where my power loss was coming from(pic 5 again). It was dynoed on E85 and had no boost leak (ran 7.25 psi) and good AFR (12.05 at WOT till redline). I was under the impression that even with blown out spark plugs it was still getting the needed amount of fuel so that is why even with yesterdays dyno AFR i wasnt too worried. (Correct me if im wrong here) Yesterday i got a little impatient so i went to a different dynojet than i normally go to. He was a great dude, building some powerful machines there. Just seemed my car's AFR weren't reading correct and when it did read good i thought it had an odd outcome. I have secondary cats still which might be clogged causing the weird readings coming out yesterday. (pics 8-10) will post more as i do more. i drive it everyday. Spirited runs every weekend. Never skips a beat. Im sure there are thing i should monitor more closely (being AFR) but it hasnt had any issues so I will let her be for now... I will be throwing on the vf650 Pulley and im assuming i will need a new belt and tune? (any info would help). As of yesterdays dyno on E85 she put down: STD smoothing 5 - 584whp and 420tq STD smoothing 0 - 617whp and 434tq SAE smoothing 5 - 570whp and 410tq (dont have the sheet for it) When i go with the 650 pulley i am hoping for over 650+whp and 450+wtq on e85 (STD) The reason i kept the dyno sheets in STD rather than SAE was because Advance Fuel Dynamics did their dynocharts on the vf650 kit in STD so i figured it would be better to compare them that way.
