Increased HP guess

I have a stock 2004 coupe (350 hp) that I just installed Dynatech SuperMaxx Headers, Hi-Flow Cats, X-pipe, Corsa Touring Edition Exhaust System, Velocity stack, and I modified (http://www.ecklers.com/product.asp?p...3&dept_id=1756) the stock air filter cover to get more flow. Does anyone have a good guess what the hp at crank and wheels would be? Any 1/4 mile et guesses?

Thanks,

Is the car A4 or a manual? Long tube headers can actually give you a pretty good kick. I run mid 12s on my 02 A4 with just long tubes, hi-flow cats, vararam CAI, 3.42 gears and tuning.

To maximize the potential, you'll need a dyno tune.

Engine is just a big air pump...u now have the capacity to flow more air, in turn you'll need more fuel.

Get a real CAI and a few more bolt ons to up the hp and get a dyno tune. With all that you would be looking at a solid 50-55hp pickup depending on your CAI and the other few bolt ons you do. I'd say that puts you in the 345-350rwhp 350-355rwtq
