Dumps for turbos?

Re: Dumps for turbos?

i run a full 2.5" downpipe, and full 2.5" magnaflow exhaust....i have no cat. on my car and i make good low end power, and top end power....but i will be adding an electric cutout for next season at the track because its a provne fact that a open exhaust after the turbo ADD's horsepower....the faster you move the exhaust through your system, the faster you will spool up and the more power you will make...

you're preaching to an automotive engineer. i agree that dumps add hp. i said that i wouldn't trade a nice exhaust note for 10 hp or so. you will see more than 10 hp, since you only have a 2.5" exhaust. i'd say put a full 3" exhaust on, but it's probably cheaper for you at this point to just add the dump. i'm interested in hearing your track times with the dump open/closed.

a properly sized exhaust isn't very restrictive at all - near 0 psig backpressure. an intercooler is more of a restriction - 1.5 - 2 psig. even a full cat will only cost you 1-2% hp - i don't think i'd notice, or miss it.
