• 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.

        Expect turbo failures at that power rate, unless people realize it's safer/better to upgrade the stock turbos CHRA!

        Listen to the expert and go with upgraded CHRA or other turbos such as 2 x GTX or a single.

        I am limited to the power I can make on my current AT. I would rather spend less money on the stage 1's atm and burn those every so often then put stage 2+ on the car and destroy the AT. I am hoping for some breakthrough stuff this year on the AT, if not I will seriously consider an MT swap. Only time will tell I guess, I am sure that the stage 1's from vargas will hold up a bit better under high boost than the stockers that I have already put through hell for the past 20k miles.
