My motor is built up currently running the bbk 70m tb. In its currenty form the TB is to small for the motor. Motor mods include
77 pro-m, 70mmtb, Embree blower inlet, 95 s-port embree, 12#s of boost, embree manifold inlet and lower ic tube, ported intake, ported heads, bigger exhaust valve,roller rockers, stage 2 dr. fred cam, sccoa headers, 2.5 exhaust dual all the way out, double spearco with shrouded fan, running close to 9:1 comp. Coymiller stage 2 bottom end.
Should I get the 75mm or the 85mm tb and have the inlet ported more?(my porter is real cheap). The car only makes 12" of vacuum at idle and there are no vacuum leaks. The current 70mm tb needs to be opened about 1/4 of inch to get the throttle right due to the air demand from the cam. Any Suggestions?
