It made 13+ psi on the SCi impeller at the same rpms, so I think 16+ psi is probable with the Si. Also have a 28T pulley in Ron's toolbox, but we haven't been able to make it work without shredding cog belts. It would spin the blower around 61K rpms, but I don't think it's going to happen. That setup will surely push close to 20 psi, but I'm not in a rush to make that work right now. For extra cooling, we added meth injection.

The car made 266hp w/ boltons and tune. 409hp w/ Stillen SC. 420+hp w/cogs. 450+hp when it blew w/ cogs and Si impeller and quite a bit of belt slip(15 psi @ 6500 rpms and held 15psi to redline).

We'll see how it does in a couple of weeks. I ran a 12.5 @ 114 on street tires with the cog pulleys and SCi impeller. I am a Novice.

All facts. Take them or leave them.
