i saw on a video i cant remember if it was RPM or another shop anyway other than i think Headers and a rotofab which made like 448 just by using the Holley Hi Ram gained almost 40rwhp dynoing 486rwhp now PTR told me they make the same HP just more TQ now also my thinking is the Holley is all aluminum and weighs 34lbs and the PTR is CF and nylon and weighs in just under 20lbs with less heat soak plus that CF lid looks killer
