Dyno Results: 313 HP at the wheels
I recently dyno'd my car and got 313 HP and 331 ftlbs at the wheels (SAE correction factor of .98). The only modifications are a 1 bar spring and PH headers.
The good news is I had over 300 ftlbs from 3000 to 5500 RPM. I do have one question: My fuel ratio started out well (12 to 1), but by the end of the run it was steadily leaning out (13.5 to 1). Kinda acted liked a dirty fuel filter, but it's been changed recently. Is this normal for CIS systems. Any recommendations out there for a what it should be for optimum performance???

Jeff,
Thanks for the post. I am looking forward to the time when I do the headers mod and electronics boost controller on my car.
About the fuel. CIS always runs clean from the factory. I had my car modified with a Rice's fuel enrichment device to prepare for later mods such as yours.

Thanks,

Thanks Sonny. Makes a lot of sense what he's saying. Although he kinda lost me on the testing portion. To do any type of air/fuel measuring, I've been told you need a wide band air/fuel gauge. The 02 sensor is not sensitive enough to measure (accurately) anything outside of 14.7 to 1. It will just tell you if it's rich or lean.
How much does this system cost? Do you replace the warm up regulator or is it an add component? My first step will be to check my control pressure, and go from there. There was another C2 Turbo identical to mine (except no headers) and he made essentialy the same HP. Although he was running to rich....go figure. I did make full torque about 1000 RPM sooner though. Can't anything be easy?

John,
The cost is under $300 and 2 couple of hours of installation time. I think it could be a DIY for someone like you.
I had mine installed during a major service.
