I've run 6.81 and over 102 MPH with just under 460 to the tires unlocked. I'm an automatic though.

475 rwhp in a good set-up suspension, trans and gearing should net 6.60s at 103-105 mph in a 3400-3500 lb car. 475 hp at the flywheel would be more along the lines of 7.20s-7.40s at 92-94 mph.

Very carefully, unless you want an excuse to buy a 12-bolt/9-inch!

Your 1/8th ET & trap speed will be completely dependent upon the tranny you're
running in combination with your suspension setup (wheels/tires too).

You can make all the power in the world and lay down a horrible run. I see
guys run 8.0's @ 90mph with 500rwhp...and I also see guys running 6.50's @
110mph with 500rwhp.

You want/need help? Tell us about your car a little more - other than it makes 475hp.... suspension, tranny, even type of car.

Heck, 4.10 may make a world of difference, but without know anything about the car, it is impossible to know how to help you.

Build a signature block to tell us about your car before you ask questions please.

I got one for you guys.

425whp, M6, stock rear w/ 3.42 and I managed a 8.1x @ 92mph with a 2.0 60' (this is on stock Falkens mind you). With a set of decent DR's what do you suppose is a realistic expectation considering the ever so less than 'ideal' S. Fla air?
