Just wrapped up a dyno session on my E92 AT over at PSI in Portland. Mods include COBB v3, BQ/WP Advanced Tuning Map, VRSF DP, AFE Stage II Pre DCI, ER CP, FORGE DVs, HPF 7" FMIC, RB PCV, Aquamist HFS4, Factory Catback w/MidCats, FFTEC 455 LPBP.
Fuel - E85 mixed with 92 octane. Around E40. 100% Meth flowing @ 800ml per minute. Although there is probably a few more HP in there with E60 but my HPFP can't handle the fuel demand at higher ethanol content with the torque we are making. Dyno room temps were in the low 60's with one small fan.
We have made a few torque related changes from the (488rwhp) pull we made on the DynoDynamics dyno. More advance, leaner air/fuel ratios, slightly different torque driver settings to allow for torque to ramp up slower making the car much more drive-able.
If I had more time I would have scaled my timing back as the car seems to like 12 ramp to 13. I think I would have made more power as my timing might have been more consistent. Every car is a bit different... and this was a max effort setup and the car delivered 484rwhp. So it's time to back it down to a happy 12 deg where it should still make very impressive stock turbo numbers if not more power. I think with upgraded intake plumbing, upgraded HPFP, and E85 with meth we could see 500rwhp from stock turbos. Do I think it's worth the effort? Nope... RB Turbo's will be next on my list of upgrades.
Stock Turbo Dynojet World Record... What's even more impressive, it was done with an automatic...
Special thanks to @BuraQ... Wouldn't be here today without you bro.
