if it takes a car that puts 198 whp on the dyno and gives it 450 whp on the dyno it is definitely worth the 7k. the srt doesn't even put 300 hp to the wheels, only around 280 whp, and it runs around a 13 flat, <- non car and driver run, i have seen the srt run 13.1. i got a 14.4 out of my stock xfire in MD last year. so 450 whp is definitely worth the 7k. i would pay that any day compared to the supercharger kit that only puts 300 hp to the wheels for 9k. oh and the 330 hp is crank guys not wheel speed max is talking 400 to 500 wheel hp. so far the srt has NOTHING for it to make it that fast Renntechs upgrade for 22k doesn't even put 400 to the wheels. its only 404 to the crank so I definitely commend these guys for getting a kit for around 7k or even 9k. search around thats' a good bang for the buck. my friend spend 30k on a civic for 550 hp to the wheels and 8,500 for his single turbo supra that has 680 whp true whp.
