After putting it off for a while I figured I better get on a dyno before the summer was up. My wastegate spring is 6 psi, but I'm only seeing about 5 or 5.5 psi at the manifold or at least thats all my boost gauge is reading. But overall I'm very happy with my numbers I didn't expect to break 200.

Real nice dyno.I hope its your boost gauge thats off, cause your making some nice power for 5psi. But your A/F looks kinda lean. Is 13:1 too high?? Stock injectors right?

370cc SR injectors with SAFC II. But yeah I think I'm goin to add some more fuel in the mid-range just to be safe.

Yeah bro, add fuel...lol. 13/1 is very lean for pump gas. It does tend to make very good numbers though. The power is amazing when you run anything leaner then 12.5's. Thats why I'm a huge fan of methonal or alcohol.

How lean can one get safely if they run water injection? I think water has the best cooling effect and still retards the gas like the two you said.

Yeah...get that fuel curve under ~12 for the mid-range and up to redline...you're flirting with disaster.

Otherwise, looks good.

I did 224rwhp at ~5.8psi...but the timing was a little rediculous. Like yours...decent power, but not exactly safe.
