ok im thinking about doing long tubes, a cc305 cam, 1.6 rockers, and a mail order chip for a 93 a4 z28 that already has a k&n and flowmaster 80 series 3 inch cat back. what kind of hp do you guys think this combo will put out?

 

probably somewhere in the 320's rwhp

 

310-330 if it is healthy.

 

310~315 rwhp.

 

320-330 if the tune is good. I would just get a hotcam, its much cheaper and very similiar duration.
