I'm putting together my friends car. His plan is 20 psi on a daily driver (headgasket is done).... Anyone vent the wastegate back into the downpipe with this setup? just curious if they had boost creep issues. He wants to keep the engine bay clean and avoid the exhaust leak sound when at full boost levels...

any input would be great! thanx guys

 

I can keep it at 6psi all day on a GT3076bb. I put it about 2 feet down the downpipe and merged them at a shallow angle.

 

thanx muchly!
