Talking New PB 1/4 CC503

Best run I've had so far. I think I can get a few tenths faster if I had a couple more runs and played with the shift points and stall more. Only got two runs the whole night because everyone kept crashing and blowing their stuff up and it took forever for the officials to clean everything up. Car has everything in my sig with stock heads. Hoosier Drag Radials were 255/50-16 on stock salad shooters. What do you guys think?

Whats your raceweight? Not to shabby! I'd expect abit more mph being at low altitude but that is moving pretty good.

Full car weight with 200lb me in it.lol I wish I thought about getting it weighed when I was there. I feel like it could have gone faster as well.

Re: New PB 1/4 CC503

I know my 99 LS1 car traps about 109-110 in air like that, and its 3686lbs with me in it. Estimated 330-340whp. Sounds like you could be in the 320-330's whp range as well since i think you'd be a tad lighter than mine... Thats about right for a 503 cam stock head build...
