Well, for what it's worth, my buddies m6 ZL1 has gone 11.9@121.5 and he dyno'd 540rwhp. That's with a 2.0ish 60' on stock street tires. I agree that 411kw = about 550rwhp, so on a good tire you should be able to go mid/low 11's at a similar MPH. You're going to need to work on your launch. Also, keep in a mind a real drag strip has MUCH more bite in it that some dusty/dirty back road, so that'll hold your Torque times back as well. I'll try to make an 1/8th mile hit with Torque some time and see what I get - I have a good handle on what my car does at the track so it'll be interesting to see how accurate it is. Torque also can measure aprx wheel HP if you put your vehicle weight in - might be interesting.
