Hey guys. I just had a viper kill.. acouple of my buddies wanted me to post it on here. the viper guy is kinda pissed off. His complaint is.. i used race fuel. 22psi hks2530 half a tank of 93 octain and 2 gallons of 100 octain. does that really help? anyhow, check it out.. the first run i let him go first.
