I weighed my car awhile back at the track and it weighs 2700 lbs his weighs 4900 lbs what are the chances I can take him on low boost which is right at 330 RWHP.
first of all, its gotta be lighter than that, my friends truck weighs 4900 lbs. last time i checked, cobras weight on average about 3850lbs (about ~4000 with driver). Your car weighs probably about 2850lbs with you in it.
if he has a 4000lb car that has 460WHP, then to keep up with him in a 2850lb car you would need 327.75WHP. (11.5% weight to hp ratio).
460 divided by 4000 is .115, which is equal to 11.5%
2850 multiplied by .115 is 327.75
If your car weighs 2850 (with driver) it should be a pretty even race.
(of course if you put it up to high boost, you would dust him)

Just FYI, torque, gearing, and weight determine the rate of acceleration of a car. Not peak horsepower divided by weight.

OZZMAN,
Where you on highway 9 south of norman around 3:45 today. I was w/ the family in my wifes speed6 instead of the 7, but I am pretty sure I saw that car. Hang on to it if you can.

Yea that was me, im going to try to hold on to it. I sold a 93 Z28 to a guy at Ft. Sill but he has missed 4 payments so im going to have to go and repo it. I sure would rather have the payments that would give me what I need to keep my 7.
