[QUOTE="NathannialD, post: 774973, member: 1149"] the reason we only do one pipe is because after both banks enter the vgt there is an opening just after the flanges in the turbine housing to equalize the pressure if there was an issue. Getting the atmo to do more work does take a little effort, we have done some vgt tuning to essentially make the turbine housing smaller on the vgt to allow more flow to be forced into the atmo. IIRC Tadd's truck with max power x turbos (88mm atmo) made 45 ish psi out of the 88mm while keeping bp around 80psi. total was in the high 60's low 70's. [/QUOTE]
