You have a slight advantage in Torque, but his advantage is in the gears & HP. With some gears & the ability to hook it balances it out. Then I'd simply race him in an 1/8 as the quarter could still be too close to call and would be a drivers race.

so heres the specs i found on his mommys car lol

stock 2003 mustang GT 4.6 sohc, auto
260 hp @ 5250 RPM
302 lb-ft @ 4000 RPM
at the """ENGINE"""

and heres mine

1986 camaro iroc-z 5.0 tpi, auto (now i have dyno'd my car with the current mods except the ported plenum) so add a few hp to it.

236 hp @ 4100 RPM
359 lb-tq@ 2900 RPM
at the """ENGINE""" ,not wheels. to the wheels it was 186 hp, 279 lb-tq

the stang wieghs 3,300 lbs
the maro wieghs 3,200 lbs

should i race him or not????

ps 279rwt is closer to 320 motor. What number were you using for a loss?

Stats though if your cars runs extremely well. Ive raced my buddys bolt on 4.6 03 gt with underdrive pulleys and 4.10 gear rear end No Tune, he only makes 260hp, vs my l98 dual cats, 3.27 gear auto. It was a DEAD EVEN RACE! I dont have any doubts that you can beat him if you know how to launch your car right without much wheel spin you can beat him. Just my 2 cents.

Whatever though. Any track times?

oh btw, when i ran my car on the dyno, the hypertech actually performed 19hp LESS than when we threw a stock chip in. then made 20 or so more hp off of that stock chip when we were done tuning.

oh and i ported the plenum AFTER the tune, so it should be more now.

so i wonder what my times will be now...

a stall like that would be a bit extreme on torque happy engine. i could never hook up with a stall like that. i burn rubber like no tommarow with the factory stall i already have. so delaying the launch to a higher rpm would be hurting me. the primary reason for a stall is so you can run a higher idle if you have a radical cam, because it not bieng able to idle at low rpm. but the only way i could use a stall like that for the "other" reason people use it for is if i had some damn soft compound drag slicks lol.

naw i wasnt gonna build it JUST to beat him. hes just one race that needs to be taken care of. but he has no intentions of modding that stang, plus its his moms lol. and he wouldnt know how to mod it if he wanted to lol
