BMW states 320hp at the crank but people have dynoed their cars at 320 to the wheels. I'm basing my numbers off of Active Autowerke's numbers plus maybe 5-10hp from the intake+exhaust, though I doubt they actually make a difference. Either way, it should be close to 400whp and 415wtq (keep in mind this is at peak power, rest of powerband is a bit lower). There's a fuel cap at 400whp so we can't make more power than that without meth or ethanol until the DME is cracked. I'd like to dyno my car and see where I'm actually at in terms of numbers. I think I'm a little below 400, probably around 390 or so. I'm thinking about making the switch to JB4 + catless downpipe though, which will definitely be at or above 400whp but I lose a little bit of low-end torque.
I should be at the drag strip this Friday so I'll be able to get some times if anyone wants to see them. Hoping for low 12s in the quarter.
