Right now i have a 95 Z28 A4 with the 3.23 rear end. right now i have a cai and planing to get the hooker catback. what kind of horsepower/ tq and 1/4 mile times will i be looking at with a stock z28 with cai and catback?

 

in good running order 270hp...

1/4mi will depend on traction and weight. i'd say 13.8

 

wow...cool, didn't know just a catback and cai would get me into the 13s like that by the way, when you say 270hp...is that flywheel or rwhp?

 

Thats rwhp. I would guess more like 265 for an a4. If you get a good launch you will be in the 13's but if not then you won't.
