Conservatively, most typically assume a 12% loss for a 6MT, 15% for an automatic, and 18% for AWD.
A stock 6MT making 310whp/330wtq would be making around ~350hp (310/.88) and ~375tq (330/.88) stock at the flywheel or 20hp and 45tq over quoted stock figures. Given the magazine numbers for the 6MT of 13.4@107mph and the curb weight for a loaded 6MT (~3,500lbs), the stock power of 350hp/375tq sounds appropriate. I've also noted that the Car & Driver and R&T 6MT M235 test cars only had 1,000-2,000 miles. I'm certain these cars get a bit stronger with some mileage. Considering that the broken-in M2 6MT mag test cars are running 12.8s@111mph and are only making 20whp/30wtq more than M235, I think a broken in 6MT M235 could be more like 13.1@109mph.
I wish I still had a 1/4 mile track nearby. I've always managed to be beat mag numbers by .3 seconds and 2-3mph and with slicks on the 6MT, I'm pretty certain 12.8s@110mph stock are attainable assuming a 1.8 60 foot. |
M2 with DCT put down 335-340whp on 93 and finish 1/4 mile in 12.5 secs. 30WHP deficit eats you by 0.3 secs and another 0.3 secs down from ZF8 in 3 shift-ups.
You'll be looking at 13.1-13.2 in 1/4 with a stock m235i ideally.
