    Cool PTF UPDATE: 553WHP 631WTQ - N54 TwinTurbo 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 4cyl 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, its 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 Click here to enlarge 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):

    What clutch are you running now? No signs of slipping with all that torque?

    Nice! Interesting peak power is at such a low RPM. It makes me want to find out how much boost my RBs can hold at 4500rpm. That power curve should haul ass in a 60-130.

    The head is our own, done by a local shop here in Canada. The clutch is the HPF Stage 2 feramic.

    Click here to enlarge Thanks. Well, peak power is dictated by torque right and what makes torque on this car, well boost Click here to enlarge there's more boost down lower so more power down lower, simple...

    I'm sure there's a bit more in it even with this setup but I really didn't want to push things further when i saw these numbers. Good enough for now given high wastegate duty cycles on the turbos. I also want to get the ATP boost datalogging sorted before any other changes to boost anywhere.

    We'll see where that top end power goes with race gas and meth instead of pump+meth. I bet it can be lifted there and possibly a bit more with some other vanos tweaks. At this point, that's obviously just a guess

    If you don't mind me asking, what change did you make between 4 and 5k rpm to get the bumps in torque over 600 ft. lbs. shown in the "all runs" dyno plot?

    Truly impressive results! Have you been to the strip with clutch yet? I am sure you are well aware of the ones that welded together on hard launches. I am about to purchase a new clutch and RBs so I am weighing my options. Even though I don't plan on going to the track, I would like to be able to do hard launches on drag radials if I change my mind.

    Hehe, well you could first do some passenger laps with me, and if you survive these drive yourself...Click here to enlarge

    As an alternative, get yourself over here next year! You're more than welcome and we could organise a cool experience for you on the Nordschleife.

    It's a shame that power can't be held out towards redline. Nice none the less!

    Also, can you comment on how much the head work might cost?

    Ya torque bomb! Click here to enlarge Never been worried about anything breaking. When/if something breaks it'll be made better/stronger just as anything else on the car. Head work price will vary depending on if you're doing the exhaust valves or not. All out on the head with custom oversized exhaust valves probably north of 4k

    I tried graphing my logs but at the moment boost is capped at 22.51-22.52psi in midrange in them. I'll post up some graphs as soon as ATP boost datalogging is sorted.

    Anything in particular? PM me.

    Any chances of getting the before head work dyno chart overlayed with the new one.

    I just noticed that as well. It didn't even have any mention of Shiv in it, so I don't see why they took it down. It is truly sad!
