My B23ft has ET pistons (9.3:1 static CR), a 19t, 4.30 diff gears, and an IPD turbo cam timed straight up. The turbo spools quicker than anything I've ever had. It's at 8 psi before 2500 rpm. Most of the time it feels like a 6 cylinder with near instant response.
Sometimes, though, if I floor it and allow boost to build from 2500-3000 rpm, the power will come on later than the boost. Does it make sense that if boost builds in the manifold but the car's not going, that the cam isn't letting the charge in?
I figure it's either that or LH2.4 pulling ignition timing. But mostly I want to understand more about the relationship between manifold pressure, cam timing, and power.
