turbo'd motorcycle dyno run

Here's a butt ugly bike I built a year or two ago, that I had yet to dyno. Just a fun little toy I made, originally planned to use it for track duty, but have yet to take it to the track.....don't have my NHRA cert yet

but here's a dyno chart and extra info if you're interested in it. It's been running for quite a few miles, I just haven't gotten around to dyno'ing it til now

Low boost (10psi), I think there was some boost creep, 210hp roughly 132 ft/lb's from 5700 RPM's to the end

High boost (16psi), 230hp, with a rough calculation of 176 ft/lbs at 6700 RPM's

The high boost run was after doing several runs trying to get the lock up clutch to stop slipping at lower RPM's.....so there was a lot of heat saturation. I think it would have done 240hp easily otherwise

All on pump gas

All in all, not bad at all. I'm happy :)

I don't think it looks too bad in that pic...
Make your own cooler for it?

yah, came off of a VW passat 1.8L turbo. Plastic tanks. Pry them off and weld on new tanks
