HELP: sucky drag racing times



VT2-500 kit, 8psi confirmed on my boost gauge. Bridgestone re-11 tires launching at 1500rpm, anything much higher and I was experiencing wheel hop. 28psi hot in the back.

Temps were high, around 84*F, and very high humidity. On my best run, it probably cooled to 80*F.

For comparisons sake, I ran a hair quicker than a c5 vette, and beat a Viper GTS. The viper's best run was a 12.8@~115

So I see that I took a huge 3 tenths from my average runs because I had a .1 second better launch. I noticed I'm chirping my tires as much as 3 times per shift, which hurts it too. So theoretically I could be running low 12s with a 1.8 or 1.9 second launch, but I doubt my traps would be 7mph higher.

I'm gonna start with a dyno in 2 weeks or so, and get my water/meth kit hooked up to counter the heat.

So here's my question -why isn't a 500hp car hitting anywhere near 120mph trap speeds? The car feels significantly stronger in cold weather, but come on... am I really gonna pick up 7mph in the traps in colder air? Whats wrong with my car?
