[ http://www.turbofast.com.au/Drag.html ] Good drag race calculator. I use 3606 for weight, enter RWHP and get a general idea. With that weight, my RWHP (367.7) it gave me 12.46828, my actual best run was 12.47, thats close enough for me. It rated 510rwhp to go 11.18, add NOS and the car is capable of 10's.
