The owners name is Jon, he's from Mobile, AL. He's been a good buddy of mine for a long time. His Z put down 595 with a 125shot. The Viper was on the same dyno and made 700 and change on pump gas and just over 1000whp on race gas. The viper was on pump gas and street tires for this roll race. The viper def. had some traction issues. The Z is automatic btw . . .
