: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!

Good Stuff, u should look into the Zemulator, or an AEM to tune your A:F
ratio, you'll be surprised what a tune will do. Congrats though on that
power band looks like a blast to drive.
