I make 710rwhp on 23lbs with a 2.9 and my car isn't a great car to gauge numbers because its a underachiever. if your car makes 20lbs and he is running like 16lbs so to say, your car should win even though he makes a little more power. Peak numbers on a twinscrew to me mean nothing. Thats why lots of guys with ported eatons would keep up with a 15lb kenne bell even though the kb read higher on the dyno.
