Gains from a larger D.P

[No Quarter]

Is there a power limit one could expect from a specific sized DP? Say 800rwhp is not possible with less than a 4"? Or any such guidlines, anyone is aware of?

Nope...never seen such in print anywhere.

Jack Cotton at www.cottonsperformance.com could discuss it with you.

what about a stock turbo on a slightly modified car...
i currently have a THDP 3" that is pretty dented up now... about 3 big ones!!

do they sell a 3.5" or would that make really no diff. on a stock turbo since there isnt that much pressure in the exhaust?

want to sell that dented 3" THDP? Shoot me a price and some info if you are looking to get rid of it.

To whom it may concern. I spoke to "uncle"Jack Cotton on tuesday, About his up coming 3.5 downpipe. He say's it should be ready by the middle to late october and he said "yes" they will fit a car equip with atr headers. He also mention the guy's who will benefit the MOST is the guy's who run a 72 or larger turbo.
