    • OE Tuning helps create the world's most powerful supercharged E46 S54 M3 - 610 whp

      610rwhp 423lbs torque for a VF Stage 3 M3 tuned by OE Tuning is now the world's most powerful supercharged S54. The vehicle was previously running a tune from VF's partner, GIAC, but there were concerns about the car running too lean as well as having idle surge issues which are well documented with VF cars. OE Tuning managed huge gains as well as a safer air fuel ratio from the previous tune.


      Here is how the car looked with the previous tune:


      Congratulation to OE Tuning and car's owner, CarbonChooch.

        What is the compression of the motor dropped to?

        Guys,

        I was there yesterday and got to meet Jeremy and company. They were doing some impressive stuff. I took a bunch of pics and some video as well.

        The compression should be 9.8:1

        Can Alpha N handle the finickyness of a turbo tune?
        or will it lend itself well to SC tunes only?

        The compression should be 9.8:1
        Why should the compression be 9.8:1? Because that is what HPF chooses?

        No, HPF doesn't use that as their CR. I'm saying his compression ratio should be 9.8:1 because that is what VF spec'd from CP for their stage 3 builds, so his piston should be those

        Very nice! What pulley combo are you running to get 16 psi?

        I dont get it, whats brentuning and oetuning?

        Also i just had to mention from what ive seen Dynapack's are the highest reading dyno's.

        This was on a Dynapak? That makes much more sense, I would deduct at least 30rwhp from that

        deduct 30 whp Click here to enlarge I wouldnt go that far. Maybe 8whp compared to a dynojet

        I've baselined a ton of cars on this dyno, and a local mustang dyno down the street, and a dynojet on the same day. They all read similar, the only thing about the dynapack it reads maybe 1% higher on the torque reading only, probably due to the lack of rear wheels.

        It is a non-adjustable dyno (no ctrl x, no temp probe in the engine bay bs), no wheel slippage, no strap bs, weather station attached to machine and cannot be manipulated etc.

        The M3 baselined at 554 IIRC before the tune.

        We also have to keep in mind that it was hot as hell out on Saturday. The temp being read in the shop was something like 98 degrees.

        But even if you put totals aside, a delta of 20 - 25 WHP on the same dyno, is significant.
