So today I began to peice together the blower setup and I actually got it to run under boost! The most I saw was 10lbs before the Bov opened and began to vent pressure. The engine did survive 10lbs without a problem so soon I’ll add dome pressure and see if I can get 15-20lbs out of it! View attachment 173169

Yay, you finally cut the drive pulley shaft to length. (That was killing me.) LOL
How does it sound, n/a versus 10#? Any videos?

Anyway.... I found my screws did not work for holding the rotors to their shafts. I replaced them with bolts.I ran the quad for about 15minutes, and no strange sound arouse. Tomorrow I’ll pull the spark plug and look at the piston for any signs of detonation and move on from there. The engine does run well with the blower on now, and I do have hope for it being blown. I’ll have a video posted on YouTube shortly. Don’t mind it won’t have audio View attachment 174619

A couple questions come to mind:
"Balance" of the rotors, now that they have a bolt through them, have you felt any extra/new vibrations? (Too early, bearings haven't warn yet? Lol)
Why not put a "key" in them? (Limited machining access?)

I did some testing over the weekend and after about 3hrs of runtime the blower steadily made less and less boost untill it was making just 5lbs... I tried putting the small pulley on, but I ended up just breaking off the input shaft on the blower from over tightening it... I Decided to just call it off on this blower setup. The amr300 just isn't going to work View attachment 175022

What failed / where was the psi going? 🤣

Now that you've got the fairings in such on, how about a wide shot so we can see the body and the blower. ;-)

Sooo i was on eBay...found a sportsman 400ho body. Should i get it? View attachment 176519

Idk, orange is my favorite color so I'm not a good person to ask. I would. LOL (I have no clue if these actually fit, I'm assuming you've done the research.)
