it deffinatly suprised me, and i am running a HF tranny, but it's cool cause i can go up to 95mph in second and it actually doesn't take to long to wind it out. I need to get a passanger w/ a stopwatch and see how long it take for 0-60 but it wouldn't suprise me to be under 6 or 7 sec., but i need to time it to be sure cause what i think the time might be don't mean shit untill i can get it on a stop watch.
