    • BMW 335xi with Tomioka Racing 16T N54 turbochargers making 523 awhp on 91 octane pump and 22 psi of boost

      These are some very impressive pump gas figures considering they come at a claimed 22 psi on 91 octane fuel from a 335xi running Tomioka Racing 16T N54 turbochargers. The output is 532 horsepower and 548 lb-ft of torque at all four wheels.


      These turbos certainly come late to the party and BimmerBoost does not have many Tomioka Racing results to point to.

      The numbers certainly are hard to argue with:


      The entire dyno graph was not posted for whatever reason which is somewhat suspect. The dyno type is a Dynocom and yes they have a reputation for reading high.

      The full modifications as stated are the 16T turbochargers, Cobb FMIC, VRSF inlets and outlets, Deatschwerks DW400 fuel pump, and a Radium catch can.

      Compressor Wheel Turbine Wheel Max Supported Power Turbo Inlet Size
      TR-TW2004 (15T) 42.0 mm 52.0 mm 720 HP 1.80 in
      TR-TW2005 (16T) 43.4 mm 52.0 mm 780 HP 1.80 in
      TR-TW2006 (19T) 46.0 mm 52.0 mm 830 HP 2.00 in

        That seems really good for 16T turbos. Old MHI technology, and not all that big.

        I have these turbos. I’d like to see a log from that pull. What kind of timing is he running?

        i run about e25 and 23psi. Jb4 with race bef. I’m waiting for stage 2 lpfp before I add any more boost and hit the dyno.

        Got them at last years Christmas sale, $2000 usd, so far they have been great bang for the buck.

        Man, I need to convince Tony to buy a dynocom. The marketing opportunities are endless.

        i didn’t buy them based on their inflated horsepower numbers on the website. I don’t believe 22psi is achievable on 91 either, but, I do believe 22psi would land around 500hp

        aren't these basically GC lites V1.0

        16T with 11blade turbine? Didn’t you guys post similar numbers on GC lite’s?

        What is your output considering you are running more boost with some ethanol splashed in?

        not sure, I haven’t dyno’d yet. Like I said above, I want to add a LPFP, a little more E, and a little more boost before I dyno. (I’m still stock LPFP).

        I have log dyno numbers between 460-520. Butt dyno says 480ish
