    Here is a reference of the latest development of Standard RB Turbos combined with TFT inlets, allowing unrestricted RB Turbo Performance on our customer car documented here: http://www.bimmerboost.com/showthread.php?62716-BQ-WEDGE-335xi-w-RB-Turbos-607-AWHP-618-AWTQ-w-TFT-inlets-w-Sub-50-WGDC Datapoints- RB Car (Blue lines) E92 XI/AWD Automatic Transmission in 4th gear. Independent results. RB Standard Turbos with TFT inlets, Billet 15T Compressor, MHI 12 blade clipped turbine, stock charge pipe Boost- Unknown (slightly below 50% WGDC) Fueling/Tuning- OEM HPFP with inline LPFP. E60. Fueling insufficient at this time and to be addressed at a later date. Wedge/BQ Tuning. VTT Car (Red lines) E90 RWD Manual Transmission in 4th gear. Shop results. VTT 2+ Turbos with no inlets, Billet 20T Compressor, Proprietary 9 blade Garrett turbine with a 15* clip, stock charge pipe Boost- ~29-25psi (slightly below 70% WGDC) Fueling- VTT Double Barrel with SteveAZ LPFP solution. 100% E85. Fueling sufficient to max out turbos. PTF Tuning. As you can see the RB car having a very evident disadvantage with drivetrain losses, manages to absolutely destroy the VTT 2+ car at low RPM's and even hang right with them on the top end. The RB car seems to have much nicer results overall considering the drivetrain losses (not even considering the 20% extra WGDC potential in the RB's yet unleashed!!!). Without going too much into the hardware decisions made in each setup, it is fair to say that one is demonstrating a MUCH better curve and response than the other… while maintaining a similar top end at less effort. So sharing this comparison graph seemed appropriate. Thanks, Rob PS. Sorry if the overlay is not of the best quality. We had to have it quickly photoshopped. PSS. Some may take note of the VTT graph NOT being the advertised 645rwhp record. We will gladly redo the overlay if anyone can prove that the 645rwhp RECORD has a verifiable MPH dyno to prove it was in 4th gear (and not 5th); as we could not source that evidence NOR was VTT supportive in providing it.

    Rob@RBTurbo started a thread RB Turbo PCV Valve in N54
    All, Firstly we are happy to be onboard BimmerBoost. It has been quite a while and for the new year we made numerous "resolutions" and one of them was to finally join this forum. In direct relation to that another resolution was to give us our voice into constant nonsense, product attacks, and deception we have seen in only one of our competitors. Being that we deal in hardware it is a great thing to address these items because as they say a picture is worth a thousand words, and we have nothing to hide. We'd agree that this thread such as this SHOULD not necessary, but it is when you realize the type of person on the other side and the amount of efforts it cost in dealing with the misinformation in the hands of hundreds to thousands of "faithful" enthusiasts. And with that it has to stop, and we will continue to squash it wherever we see it. This concept was in fact one of our other resolutions for the new year. So without further ado, here are the quotes that were made by said competitor and pictures of their product exposed. Keep in mind this is the same valve and part number for part number of that we have been using since 2012. The direct copy of the part combined with an of all things "up charge", is lesser importance to us than that of what lies behind the principal of these below quoted statements. For those who may question us as using this valve, we openly invite any random customer out there to dissect your RB PCV valve to confirm and we will send you another free one (limited). We will do this as we have again nothing to hide, and it is worth it to prove any point on the matter. We will further add that there maybe more of this to go around. Consider it an advanced warning. We have had it over the years and it is time to clean up the streets. Thanks, Rob

    Say hello to a new vendor and a new tuner on the scene, Miami Tuning Group. Many of you have seen a lot of S63TU tunes have hit the market in short order as F-Series ECU's have been cracked. What will separate these tunes is namely pricing and features. What is nice to see here are timeslips accompanying the dyno chart. How about cracking 130 in the 1/4 mile with just a tune? This is a Florida result so keep in mind the fuel is 93 octane pump. The M6 turns into quite the beast with just a tune so imagine the possibilities with a race gas tune and bolt ons. Regarding the output figures the S63TU goes to 588 wheel horsepower from the stock 524 wheel horsepower. The peak torque figures rises by just under 100 lb-ft of torque at the wheels getting very close to breaking 600 lb-ft at the wheels. You should also notice the torque gains are through the entire curve. Expect to see more MTG over the next few weeks.

    Considering RB and Vargas use their own wastegate design is it possible that the WGDC between them is different? For example, and this is only for example sake: Vargas stg2 turbos will hold 21psi of boost at 4000rpm with 70% WGDC RB's new fully upgraded turbos will hold 21psi of boost at 4000rpm with 55% WGDC Now what I'm asking, is it possible that even though the RB WGDC is lower is it possible that the actual flappers are applying a similar amount of pressure to the CHRA. To put it another way is it possible RB's wastegate are stronger per WGDC percent then Vargas's? The reason I ask this is because of the recent thread BQ/WEDGE 335xi w/ RB Turbos - 607 AWHP / 618 AWTQ w/ TFT inlets w/ Sub 50% WGDC. Awesome results, They seem to be accurate. Congrats to everyone involved there. :eusa-clap: No doubt Rob really has his hybrid setup on point now. But what I don't believe is these are 700whp turbos. I'll admit I'm no pro on turbo technology and from my armchair I can only speculate but considering people are strapping big singles on with basically no intakes to make 700whp I'm thinking these things must be about tapped out airflow wise mathematically. (I know these numbers have been crunched before, I'll admit I don't remember them or how to find them) So whats going on here? I'd love to hear everyones opinion and the math as long as vendors keep it clean. :paddle:....;) thanks

    Hi everyone, Im from Spain and Im a newbie in BMW Performance and their ECUs. Ive just installed a JB4 G5 ISO with DCI and I would like to post the logs to comment some issues. First: 335i 2008 N54 DME81 98RON (93 octanes) JB4 G5 ISO 28.5 DCI Stock First, pull in 5th gear. Map 5 FOL: 65 FUD=2 DWP: 100 BDC: In 3.200 rpm 3500-5200 APRENDIDO by sserx_r, on Flickr Second, pull in 5th gear. Map1 FOL: 65 FUD=2 DWP: 80 BDC: In 2.500 rpm MAPA1 by sserx_r, on Flickr Third, pull in 4th gear. Map 6 with target up to 16psi 4.500-5.000rpm FOL: 65 FUD=2 DWP: 80 BDC: In 2.500 rpm MAPA6 by sserx_r, on Flickr Fourth, pull in 5th gear. Map 6 as previous one. FOL: 65 FUD=2 DWP: 80 BDC: In 2.500 rpm MAPA6_2 by sserx_r, on Flickr I would like to know about the ignition corrections all the time in every map, is it normal? And the trims are elevated specially in map 6 after the corrections in DWP and BDC, but I dont know if these corrections have to do with. Thank you to everyone in advance and regards from Spain.

    I bet the Porsche has around 590HP (crank) and the M6 which in fact is convertible should have north of 700, G-Power tend to boost around 0,4-0,5 bar, so with the KKS-exhaust, my guess is 720-750PS

    Vargas Turbocharger Technologies is proud to officially announce the release and immediate availability of our Single Barrel HPFP Upgrade! The 100% completed kits are in stock and we began shipping units today! Thanks again to all those of you who pre-ordered and have been waiting patiently. Were very excited to get these units out to you and looking forward to seeing how your cars perform. New orders (while the first batch lasts) will be processed and shipped in 3 - 5 business days. Single Barrel Logo by VargasTurboTech, on Flickr Product Information: The "Single Barrel" HPFP kit replaces your existing HPFP. Using our mounting system the new pump is relocated in the accessory cluster to be overdriven by the belt. Coupled with our new feed line, and rail modification this provides enough fuel for around 550WHP on 100% E85, with blends it can support even higher. We went through numerous pulley designs to find the optimum overdrive speed that would optimize flow, pressure and longevity of the new components. Pricing for the "Single Barrel" kit is $1199 Single Barrel kit contains: - VTT Billet HPFP drive housing - VTT Billet Stainless Steel drive shaft (pre-assembled in housing) - High speed German ball bearings rated at 17,000RPM (pre-assembled in housing) - VTT Billet HPFP pulley - VTT HPFP housing mounting bracket - VTT Billet stock location HPFP block off plate - VTT High Pressure feed line - VTT Low Pressure feed adaptor - Properly sized drill bit to modify stock fuel rail (this can be done by any shop) - Water line modification parts - Plug and Play wiring harness - All hardware required for assembly FAQ: Q: Will this set up work for me if I have stock turbos and just want to run E85 without worrying about mixing? A: Yes you can pull up to the pump, fill up with 100% E85 and not worry about running out of fuel with as much power as you can possibly make with stock turbos. Q: Can I run mixes of E85 and pump fuel with this set up? A: The system is 100% compatible with Ethanol (E85) as well as regular unleaded pump gas, and will supply significantly more total fuel volume with either fuel, or any combination of both. Q: How much power does the Single Barrel Kit Support? A: When coupled with adequate supply from the LPFP this kit has been proven safe for up to as much as 550rwhp on 100% E85 Q: What happens if the belt or HPFP fails? A: BMW set up the HPFP system so that even if the HPFP fails the LPFP will continue running and bypass through the pump and you can limp the car home. We actually unplugged the "Single Barrel" system and drove the car for 30 miles with no issues except a limp condition and low power. Q: How hard is it to install? A: Installation can be completed by the average DIYer in about 5-6 hours without any special tools or about 3-4 hours for a shop. Installation instructions: Installation starts with intake manifold removal, then high pressure feed line removal followed be replacing the stock HPFP with our block off plate. Then you will unbolt and reroute the LPFP line to where the pump will now run. Followed by plugging in the harness extension and then you can reinstall the intake manifold. With the charge pipe still out you'll remove the cooling fan, unbolt the 2 bolts from the drivers side motor mount and raise the driver side of the motor to allow easier access to AC compressor. Remove the 3 bolts holding the AC compressor, install mounting bracket over the AC compressor using the supplied new bolts. Then there are supplied instructions to help you modify the water line so that it clears the pulley. Now you're ready to lower the motor back down re-install the bolts, and attach the HPFP to the housing. At this point you're almost done; just reroute the LPFP feed to HPFP and connect it, install the new belt and reinstall fan. Finally remove the stock fuel rail which you or a shop can modify with the supplied drill bit and install the high pressure feed line from HPFP to rail, reinstall charge pipe & intake, purge system, and start vehicle. We did our best to not make the kit/install invasive but in order to mount the pump in the new location you do have to modify one water line, and bend an AC line out of the way, everything else is bolt on making it easy to return your vehicle back to stock. If you choose to go back to stock at any point you would need to purchase a new water line to replace the modified one. If you have any further questions feel free to post them in this thread or send us an email.
