stock c5 tranny power limit?

**ff_jeff** · 06-19-2009, 08:36 AM

Anyone know what the stock limits are? Can I put 10psi or HCI and headers on? or will I need a built tranny for that?
BTW its an A4

I believe 500 rwhp is the usually the max. 10psi will put you around 550 or so but you MAY be ok. It really depends on how you drive it. Start hooking up and parts break.

I agree. The t56 seems to be a little stronger than the autos, but 500 horsepower seems to be a braking point from most of what Ive seen. Maybe 550 with a t56, but you need a better clutch when you get much past 400 or so. His being an auto, 10 psi will ruin his stock tranny, maybe not at first, but soon.

Although if you run slicks, a tranny can go at any horsepower. among other things. Like you said, start hooking up and and parts break.
