    • 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!

      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):

        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!

        I know it sucks as it is, but it would suck even more if they take down Jake's thread since he is a vendor advertising research/findings!

        No its not, Jake@PTF created a new one, but someone else made one this morning.

        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.
        Nothing in particular or anything that may give away any "tricks of the trade" lol. Just the default parameters, I'm mainly curious as to the MBT given this boost curve and the WGDC values. A before and after log would be great(I'm sure there are dozens of your recent logs available but I'm too lazy to dig around lol)

        Ohhh.....there were two posts then?

        Only Jakes is left.

        Holy crap!!!!! 630 ft/lbs O.O


        Amazing work! A little drop in compression and some more breathing room, the things you can achieve!

        What caused the dip in the graph at around 3,500 rpm?
      1. dzenno@PTF's Avatar
        dzenno@PTF -
        That step is there due to the way boost was set to build, needs cleanup

        I know you don't want to hear it but a G5 ISO would be perfect for what you are doing here. It has N20 TMAP support and allows up to 24psi to be set by RPM. Just enter the boost values you want by RPM and done. Click here to enlarge

        I'm probably in the minority on this forum, but factoring in the cost of the headwork on top of the RB's, I'd much rather just get a single. Either way these results are very nice. When are you getting the upgraded intake pipes?

        Sooner or later motors will start letting go and while you have it apart this might make a great mod. My interest is piqued, at least. Click here to enlarge

        I would really live to see pump or an e85 mix solely in there. I may be in the minority buy meth doesn't mean shiite to me...

        Very nice numbers. I'm sold on upgraded turbos with E85 making big numbers. I don't think anyone will argue that E85 won't hit 600whp with upgraded twins at some point in time, even with a stock head. I think it's cool you did the head porting, but for most people spending north of 4k on porting is just not realistic. All in all I'm really impressed with the work you're doing with the COBB ATR tuning.

        Bigger turbos bigger reward from the head work. No one here is comparing value for the money out of a larger turbo setup vs. the head work. Hope you can see that part of it.
