Re: dumptubes: re-routing vs. open
I remember reading something from Evan's site about why you should rerout the dumptube, behind the downpipe, but I can't remember why and totally lost the link....damn it. It's a lot of modding, but just to keep the heat of the exhaust fumes away from the motor, I would reweld into into the end of the DP

Re: dumptubes: re-routing vs. open
one thing about an open w/g dump is getting accurate AFR's after the w/g opens, unless the o2 sensor is in the manifold, but if i remember right its supposed to be post turbo right?

Why would the A/F ratio change when the waste gate opens?? Yes post turbo

Re: dumptubes: re-routing vs. open
gen4acclude got my point. i dyno'd my car with an open dump, and i was lean in boost after the w/g opend. so i retuned and the car ran like ----. i put it back to the basemap, after my last pull and i made best power, so i kept it there and babyed it back home. so than i made up a tempory dp with the wg rerouted into the exhuast and i was in the 11's @ wot when the dyno wbo2 was shoing mid 13's. basically i had a good tune, but my afrs were thrown off because the dyno wbo2 didnt see the exhuast from the open w/g
