2000 a4 rwhp guess after mods
 

Not sure where to post....so all m trying to do is be able to handle coyotes and those 392 challengers but wanna keep the drive ability.
Decided on cam motion ls1 stage3 cam(218/224-116+3). Stock 243's ls6 intake with long tubes and full exhaust. No cats, 3:73 and no stall yet. I'm hoping this will be enough, I'm guessing around 360 at the wheels??

360-410

I notice you're in California. How do you get your car smogged without cats?

Apparently it's a county thing, not state. Only smog when registering or changing names. My brother lives in Long Beach and has his truck and fox body registered in my address.

A stall will eat some horsepower on the dyno but will be faster on the street and track

350-430.

Thank you! I live in Kings Co. which I thought would be rural enough, but we smog every other year. I think the San Joaquin Valley must be considered a smog zone, where Imperial Valley is not. Our lovely state operates in mysterious ways.... lol
