• PRO TUNING FREAKS Cobb AP tuned upgraded turbo and ported cylinder head N54 E90 335i hits 553 wheel horsepower 631 wheel torque on pump gas and meth - N54 Twin Turbo World Record

      Last night I hit the dyno to see what the car can do with the new ported N54 cylinder head, RB turbos, 3.5bar TMAP sensor from the new BMW N20 four-cylinder motor, FBO (catless), pump 94 octane and meth, stock turbo inlet pipes. Key thing here, this is with a tune that sees ZERO timing corrections everywhere on all cylinders and timing that is set right at MBT for this level of boost and this car's given octane. I've run the car on the street with this exact setup this morning, number of pulls, it's pretty ridiculous.

      553WHP/631WTQ - PUMP GAS (94 Octane) + METH


      In terms of the tune, it was running more than 22.5psi in midrange, 19.7psi peak at 6k rpm, 17.5-18psi at redline. Logs of actual boost in midrange aren't available as I found out that ATP's datalogging needs to be updated to accomodate the 3.5bar scaling. I was going off my p3 gauge for midrange boost when pushed past the 22.5psi datalogging limit. I don't recommend this to anyone before ATP is updated for 3.5bar datalog scaling, it just had to be done last night and I decided to push on as I get to do what I feel is best for my car LOL and that's make some power

      No leanouts or fuel issues. LTFTs goes down to zero during the pull, STFTs trend to high negative 20s with meth. The car was running close to if not 100% meth, three 1.0mm nozzles, two of them in the FMIC outlet silicone coupler and another up in the ER charge pipe past the elbow.

      I'll be fine tuning things over the coming days but to be perfectly honest and blunt, last night was about turning things UP and NOT fine tuning. It was to find MBT and push boost as far as it can go while limiting wastegate duty cycle to about 73-74% everywhere especially past 6k rpm. It was also to experiment with various VANOS changes. I experimented with higher wg duty cycles before and RBs didn't like it. It also introduces too much backpressure into the system even fully catless that the car doesn't like it.

      So, is there more power left here. We'll see when the intake pipes are swapped for something better flowing. @George Smooth reported +19whp at his high altitude in South Africa so possibly another 20 in there without any changes. Then there's mixing race gas or E85 into it to see if there's anything there in terms of additional power through more timing. All out its very possible this will be a 575-585whp setup once all is said and done, dare I say 600 LOL

      Other runs from last night:


      By the way, on Smoothing of zero the car made 555WHP Nice even number easy to remember

      When that torque hits it feels like a big turbo came on!! Swoooooosh!

      EDIT: Some people asked to see the conditions from the dyno, STD correction factor as well as the same run but in SAE. Here they are below:

      CONDITIONS AND STD CORRECTION (i.e. STD resulted in 1.00 correction, so no correction basically):



      SAE numbers for the same run (SAE correction was 0.97, so 3% lower than STD):

        Thanks @DefactoM6 . Can you expand on this comment a bit with respect to the N54?

        About torque, pulling 0.9G on the vbox past 100km/hr tonight is....leaves you a bit breathless hahahha

        jp,
        I appreciate your point. I think the point dzenno has made is that there is much power to be made via better flow via porting in the cylinder head. In the end, everyone in the community benefits from this sort of testing. Singles or duals issue is irrelevant really-it's more about pushing the platform and learning from it.

        How big of a difference did the headwork make?

        To the guy saying he would rather get a single than do headwork on top, it depends on your goals. If it was me I'd do headwork with either turbo setup.

        Yes i think my post(s) were taken the wrong way. I appreciate what he's discovered on the head front for sure. I'd love to see the same head work done on a single turbo car

        If this motor stays together I will be one happy man. This speaks volumes for the strength of the n54, especially making that torque down low where cylinder pressures are higher.

        Promoted to front page with minor edits. Didn't feel like rewriting the whole thing, it was good enough but Dzenno you need to double check your posts. Or I guess that's my job. Either way congrats.
