ya in a god way. i dont think there are very many people at all with built motors and probably almost none with the Si. you'll most likely be limited by belt slip. Hopefully, not until you see 17+psi

Did you upgrade the Intercooler with the build? and do you have a revup or non revup motor?

please let us know what your serp pulley size is and cog pulley sizes are....this will make a big difference on numbers it will make on the dyno. i have a rev-up engine, but the non rev-up cog setup with the 2.87 pulley.

He should definately be much above 15 psi.
I just logged 14.8 psi at 6450 rpms.

A little street tune also improved my A/F. Still needs some work between 5300 to 5700 rpm. I'm seeing 100% IDC (AF holds pretty steady, but "thats all shes got captain) now with 650cc injectors and some shift knock when I let off and get back on it. So I can imagine with a built motor, there might be fuel delivery issues at redline.

You have a rev-up motor? So stock cogs are 34/32 (as corrected by Jet Mech- 34/28 would be huge with a 2.87!!)

what rpm did you see 12 psi? I'm seeing 12 psi with a 2.87 and stock non-revup cogs (32/28) at 5700- 5800 rpms. Cant wait for the story !

Hopefully you'll have A/F, boost, Hp and torque charts! We love pictures!
