Nice test. Too bad it tests nothing other than recirculating dust will eventually all get picked up by the air filter as the holes get plugged.

And hook up a gage to your aircleaner when you get a chance. Tell me what it reads at idle, 2000 rpm, 3000 rpm, 4000 rpm, etc. Tell me if you get 26 inchs of water column. Or 31". Or maybe none, hopefully.

And 100,000 miles on track and off? On the same engine? What kind of race track is this and who built your engine?
