    • BMS (Burger Tuning) hits new N54 stock turbo Dynojet dyno record with 461 rear wheel horsepower pull

      With all the discussions as of late regarding upgraded turbo options for N54 inline-6 twin turbo based vehicles the stock N54 turbos have not been getting a lot of love. Well, in comes BMS to remind us just how much power the stock turbos can make these days. The N54 has come a long way and BMS was able to squeeze out 461 rear wheel horsepower on a dynojet in STD correction. Also 510 pound-feet of rear wheel torque.


      Mod list for the car is as follows:

      B4 G5 ISO
      BMS back end flash -- "race" file
      BMS downpipes
      CPE intercooler
      CPE chargepipe w/ tial valve
      BMS DCI
      BMS OCC
      Spec clutch w/ steel single mass flywheel
      BMS 2.2g meth kit w/ 80% ethanol / 20% water, CM12 nozzle
      E40 fuel (40% E98, 60% pump 91 octane)
      "Option2" inline booster pump

      At the 20.5 PSI of boost on the turbos necessary to hit these peak figures it is doubtful the turbos would last long. This would likely need to be dialed back for any extended use as the turbos are simply being pushed past their limit. Still, nice to see just how much can be extracted from the N54 stock turbos.

      Nice work by BMS, graphs below.

        C'mon LM, my car never fell past your rear quarter panel...at all!
        I have a manual...you have DCT, not bad at all I'd say. You don't agreee?
        And on pump gas I make 420something.

        Mine? If so thanks for the tip! I was shifting around 6500rpm.

        Def running it out too much.... I think with most N54s the optimal shift point is 6200 RPMs. Just check one of your old dyno pulls & you could prob see where the power starts taking a serious dive

        Thanks. The torque seems to take a serious dive the horsepower not as quickly. But 6-6200rpms look real good.

        Agreed, dynojet has the largest reference point.

        (I'm a bit spooked on the FTW myself... We put some in the N55 and it seemed fine but a day or two later it's misfiring randomly. Coincidence? Not sure... But I won't be running the stuff anymore unless absolutely necessary. e.g. if the car does 11.001 or something)
        Why would the FTW Purple cause misfires?

        That dyno has also given results on the E92 M3 of over 400 whp with bolt on's... I feel it reads high.

        It's situational. A bunch of torque at 2000 rpm means nothing even if you are making big peak HP at a high redline especially considering you'll never see 2000 rpm during any WOT shift. I'll take the peak HP at a higher RPM in this example.

        400 WHP on a stock motor isn't unheard of, it's only a 50-60 WHP gain over the stock baseline but it's def got to be the perfect combination of parts + tuning (just like the N54s over 400 WHP on pump gas). Full catless system, pulley, drop in filter & a custom tune should do it.

        No love for @Njz who's put out 469/491 on the Undercover dyno?

        i ll be back up on their dyno next week and should put up some even better numbers since my last runs were without meth and with a $#@!ed up fuel system. Fingers crossed, turbos may let go on me though, we will see.

        Garth sent this over to me, here is the 469/491 run. I can post log as well to show no meth and HPFP failing miserably in the midrange.

        Dynomite, Garth assured me that while its not a heartbreaker dyno it does typically read lower than a dynojet. @undercover please confirm.

        Yea, it's pretty clear your HPFP crapped out with that matching dead spot between 4.5k-5.7k

        Undercover uses a DynoMite dyno & it reads spot on. My FBO Stock Baseline ran 270 WHP / 290 WTQ, so it's exactly where it should be (especially with mods installed).

        yeah we feel we could have continued making torque since the peak was right at the HPFP fail point

        It's great to see a record WHP spinning the small N54 snails w/meth patches & racegas mix. But, it would be nice some track results & long term real world test. Expect turbo failures at that power rate, unless people realize it's safer/better to upgrade the stock turbos CHRA! You can ask Ak335i he'll tell you a story running that amount of boost with his JB stock turbo against Buraq 335is & what really happened that he ended up upgrading his turbos =)

        If you don't use the compressor/turbine maps & do your own plotting. Something not nice it's going to happen at that +20psi IMHO. We have achieved much better results & reliability on turbo cars by doing this homework. Rather just hyping the boost level & adding patches.

        My runs were not with meth and simply used a high(ish) blend of e85 which is not hard to find in most places and is cheaper than 93 oct (around here at least). I am aware the stock snails will fail soon and plan to move to vargas stage 1/2 once these fail.

        Good thing I'm sub-20 psi Click here to enlarge I mean 100% honesty, tuned or untuned the turbos on the N54 will eventually have to be replaced (whether it's WG failure or from over spinning them), at that point you either replace or upgrade to something higher quality, ie Vargas
