gt28rs dyno part 2

[statik]

First dyno I made 253/210 @ 10psi pretty much stock motor. This time I dynoed with my built blacktop head, hks step1 264 cams, z32 maf, 740cc injectors enthalpy rom tune, afc neo, and a tomei expreme







330whp/310tq

The boost is falling off in the upper RPM range, I hate the profec b spec II, need to play with the settings more. AFR is a tad too rich but I don't think leaning it out any will see much more power. I could make a bit more power at 18 if the boost would hold to the end, but I doubt id see any more than 340. The manifold design is meant for low end/response rather than top end, so im pretty happy with the results, its plenty fast for me.
