Okay, so quick napkin calc:

SD-510 has approx. 10 cu. in. displacement.

I had my engine idling at about 800 rpm. Assuming the compressor pulley is approximately the same diameter as the crank pulley:

At 800 rpm, compressor output = 4.6 cfm with no backpressure

If the discharge connection is 3/4", then that is approx. 21 ft/s discharge velocity. Yeah, I guess that's about what I felt.

:shrug:

At 2000 rpm, compressor output should be about 11.6 cfm with no backpressure, so looks like I need to figure out a hand throttle
