This combination isn't really ideal, but the owner got a good deal on a high compression stroker shortblock and really wanted a KB supercharger so with low boost and a good calibration he's got a pretty stout street car. It's not a record setter, but I thought it came together pretty nice and the power isn't bad considering the 11:1 CR and stock 80mm TB.

I hope in the future I can get him to step up to a larger TB and some meth inj. or a race fuel calibration. This combo should make some pretty good power then.

Anyway, I thought it was pretty neat. Hope you enjoy.

around 12.0 afr - dang. American cars can run lean on boost.

It's really at 11.5-11.8. I had a WB sensor in the header collector that was logged with the rest of the engine parameters. The graph is the dyno sensor in the tailpipe.

that sounds better.

high compression plus lean 12.0 plus kb heat equal meltdown.

E85 and turn up the boost.

That's what I'd like to see happen.
