Aright Im in a debate with my self, my 2003 Cobra is begining the change from fast (645RWHP) to a absoulte street monster (looking to get 900+ RWHP). Its getting a new heart soon thanks to Modular Mustang Racing engine, stroked, bored to a 5.3 stage 2 comp cams on and on. My debate is Ive always used Kenne Bell chargers and I love them, but Whipple has been getting some awesome reviews. My thing is will I really get that much more power with a Whipple 4.0 VS a Kenne Bell 2.8????
