Here in Las Vegas, we end up dynoing vehicles in the middle of the night. I had a 10PM dyno appointment at Doug's Dyno so ambient temps were only in the 90's.

I made a initial pull at 28 PSI with 100 unleaded octane in the tank and ended up. 501 WHP @ 6181 RPM : 438.6 ftlbs @ 5641 RPM.

When boost was raised to 29.5 PSI the final numbers came in at...

517.9 WHP @  6402 RPM

445.4 ftlbs. @  5726 RPM

The single Walbro prevented me from raising the boost any higher without the AFR's going to lean.
