Video makes it look a little worse than it was. The guy at the truck at the end said it was about 2 lengths. I need some more mods!

Damn those vettes run !

You need more boost bud ! Then go give it a rematch !

 

Good run but surprised he beat you you should have him covered fairly easy. How much boost are you running?

 

I would have figured so too. Running around 7psi. We were both on street tires , so neither one of us could leave hard. I'd really like to get my setup running strong. I did do some power to weight ratios to make me feel better. I'd need 540whp to have the same power to weight as him. Ricer math FTL

 

Just bump it up to 12lbs and let it rip you will have that Vette beat easy.

 

I would, but I'm running pump only. Also I've got about a 3psi spike on shifts. So say I run 10psi, I'll get a 13psi spike.

 

there are people running 17lbs on 91oct.
