This didn't take long - tuned 335 dyno test

[JCL]

While there are lots of rumours that the 335 is making more than the BMW-advertised 300 hp (one magazine saw close to that measuring RWHP on a dyno), presumably so as not to take sales away from the upcoming 400 hp M3, some just aren't satisfied. This team used a new engine control map, combined with 94 octane Vancouver fuel (which is apparently a world away from the 91 octane available in California, according to the tuner).

The result: 330 whp, 365 ft-lb torque, with a calculated 60 hp/85 ft-lb gain over their baseline run. That was with standard exhaust systems, all cats still installed. Impressive. The two owners seem to want to remain anonymous, something to do with warranties....

I wonder what the peak will be?

Thanks for the link. I remembered seeing some discussion, but not the details of the dyno test. Hmmm, September 29 - I was vacationing in Tuscany, drinking Brunello in Montalcino (seems so long ago now, lol).

It seems the tuner now has separate results on two customer vehicles, with no exhaust or intake mods. There is apparently a new map coming for higher octane fuel that will see an extrapolated 400 flywheel hp, in the same league as the new M3. Quite detailed engineering, reading his website. All that, and apparently undetectable.

330 rwhp on oem exhaust and intake, very cool. This is getting very exciting!
