    • And the BMW N54 horsepower record officially stands at 725 wheel horsepower - E92 335i with Vargas VTX-R 63 Stage 3 turbo upgrade, Cobb Flash, and PTF Pro Tune

      Well, it seems the back and forth of N54 tuning horsepower records is over... for now. Earlier this month Vargas Turbo Tech and Pro Tuning Freaks (with a Cobb flash) set the N54 hosrepower record at 693 wheel horsepower. That basically obliterated what anyone else had hit on this platform. A competing tuner with a single turbo (the Vargas VTX63 upgrade consists of twin turbos) N54 upgrade kit out of nowhere pulled out suspect numbers that eeked out a few more wheel horsepower.

      This became an ego pissing match of sorts but Vargas and Pro Tuning Freaks went back to the dyno to make some adjustments and managed to surprisingly quickly and easily take the horsepower record right back (and where it rightfully belongs due to the breakthrough being thanks to the Vargas work with the High Pressure Fuel Pump) with a 725 wheel horsepower pull.

      A video is included below along with two graphs. The E92 335i is equipped with a Pro Tuning Freaks pro tuning using the Cobb flash system, 109 octane race gas, meth injection, and of course the Vargas Turbo Technologies VTX-R 63 (GTX2863R) twin turbo upgrade and HPFP upgrade.

      Congratulations to Vargas, PTF, and Cobb for pushing the platform into new territory.

It also took a forced revision after ~1 full year of being on sale for Shiv to offer the 6466 turbo option, otherwise the Vargas Stage 3 (and remember this isn't the Top Tier Kit) would've walked right on by unchallenged.
        true, this is on the GTX2863 correct? 2867 would be another decent step straight up.

        I agree. Here's how I picture it. Lets say its 60 roll, the ST car will probably get a little bit ahead but the TT will pull on the higher end. From that point onto the next shifts, it'll essentially keep pulling farther.

        Boost to HP relationship between the 2 setups is very similar.

        First im man enough to admit you where right. But like I said my issue was with the way you presented it. You talked about torture testing as if you knew what they did. but did not present any data to support your claim. you could have been just speculating ,guessing, but I took it as you knew of a sitiation that involved said engine put through the paces.

        Not to mention... Last air strip event i vaguely remember certain st cars getting walked by.. Just about everything? Even rb equipped ones?

        I take it that you've never driven a small displacement, big turbo car at the strip before? Sure, modulate the throttle for throttle control Click here to enlarge

And even then, the sharp torque increase vs the broad increase of the Vargas setup will be much harder to control and induce more wheelspin.

        Your interpretation of that graph is pretty far off.. Also your explanation in regards to power delivery/traction clearly shows you have very little experience driving a high horsepower RWD turbo car.

        @VargasTurboTech @dzen

        Do either of you think there might be more power on tap if bumping the downpipe flange size up to true 3" and a better flowing exhaust (like the VRSF 3.5 single-pipe or a custom 4" like Ak335i)? I've seen enough Supras in this power range that saw good gains from increasing the exhaust diameter due to the restrictions at the head (and it looks like you're seeing restrictions at the head).

        How much boost was this? Great numbers guys, getting me excited to get back into the n54 or 55 game!

        Agree. Shiv is just running around trying to steal some of Vargas' thunder & still appear reverent. When he thought he had the hot ticket he was not interested in the Vargas BBQ. Now he is playing catch up & is just looking for exposure like he does not have enough already with a new world record every twenty minutes.

        BTW has he deleted all those obsolete world record claims yet.Click here to enlarge

        The 725 was made on 28 flat. D can get into specifics if he chooses, but with some vanos tricks we were able to get more power with less boost.

        So you are pulling the kit to start production, or revise the manifolds?

        Yes I know. My question is the reason for pulling the kit. Revise the manifolds and do more testing? Or just revise it and send to DOC?

        Start production, the manifold revision is basically telling Doc Race to use 1.25" Weld els instead of 1.50". A bit of interesting reading in this thread about 1.25 VS 1.50. I wanted to try 1.50 and see how it spooled, its bit slower then we wanted so production will be getting 1.25. Its not uncommon to pick up 80+ Ft Lb's of torque down low and mid range going with 1.25". Most all of Full Races manifolds are 1.25". Doc Race let me know their supra manifold is 1.25 and is good for 1300 HP so it will flow plenty for what we need.

        Sounds like a plan! Good luck.
