| On Saturday I met up with a few other tt.net members; RAGTPZ, SilverTwin(OH), and Spddracer for an impromptu dyno session at Precision Autosports in Beavercreak, OH. When I first put the car on the rollers the AF ratio was suspiciously lean and we tried to correct it with the SAFC II but it never
resulted in any lowering the AFR. It was later discovered that the sniffer wasn't working correctly and we put my car back on the
dyno for some more runs after adding some 115 octane. I was disappointed that I didn't get a pump gas tune for the car but I guess I'll get that done in the spring. This dyno chart shows the difference in my old setup (red run) which was stock exhaust manifolds, stock auto intake cams, stock flywheel, .86 ar turbine housings The major changes are RPS flywheel, MSP manifolds, .64 ar turbine housings, jwt 500 cams, and ported heads. (blue run) Both charts are on race gas and 23 psi.
The changes I did resulted in what I was anticipating by moving the power band to the left and up. The car is much more fun to drive now that lag is less. Now I just need full 3" SZ exhaust, larger intercoolers and piping and then I'll be happy.... haha it never ends!
