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.
