That is great information on the stock Backdraft sidepipes, thanks for posting it. I was looking at Roush's site and it looked like your engine is rated at 515hp, but if your putting out 470+hp at the rear wheels, so you must be close to 560hp. Do you know what the rated hp is on your engine?
Funny you mention the air cleaner top, I just picked one to put on when I go drag racing this spring. My aircleaner has a polished aluminum top, but sits below the hood scoop, so the air passes over rather than straight into the aircleaner, I think it will help get a bit more power. Right now, the AFR heads and cam + labor I am going to add will set me back $3,000. I should pick up about 75 hp, putting me in the 525hp to 535hp range. I'll post the new dynosheet then, maybe I can close the gap a bit (for a lot less than a new Roush).
