Keep your two cents. My buddy has a TT 5.0 at around 7 psi and he's making over 700 on a stock bottom end. I wouldn't bet money against Whippled3v's claim at that psi with a built motor.Also there's always claimed hp with no dyno sheet or estimated as you call it. there is a very big difference between 13 psi and 7 but like I said before I'm sure both of your cars are very fast I'm not knocking either of you. Just putting my 2 cents in cause its my constitutional right ��
