Without the air pump can you still pass emissions?

no.

i am new to turbos, so here is the million dollar question of stupidity....... *drums* ........ the exast goes through the turboa nd spools it then exits though the back of it. What is that pipe ont he bottom for? letting off extra exast pressure??

anyone? https://www.nopistons.com/forums/pub..._DIR#>/sad.png

Thats where the single wastegate goes . https://www.nopistons.com/forums/pub...IR#>/smile.png

Actually yes. It all depends on tuning. Seen a bridgeport motor pass emission with a Cat https://www.nopistons.com/forums/pub...IR#>/boink.gif

Very nice!

Hey Sean, why do you not have the GT35/40 listed on your web site or am I just blind???

Wow.
