I was running an X-Force 3" Bellmouth dump with my HKS turbo, never had an issue with it. Its now been chopped/modified to a v-band and wastegate plumbed in.
Car sounds so awesome on the new engine, its not just turbo noise all the time like it was with the HKS turbo, sounds raw engine, love it. The SS2 is so much quieter driving around off boost, I've only hit about 3psi so far as I've only tuned it enough to just get it places, but I think its going to sound/go pretty good at 24ish psi
Got a 4" intake made up today, its a bit busy around the exhaust side of the engine. Few more things to sort out but should be getting tuned in early January:
