Just wondering what the average person sees with the installed pulley?
Avg I see is 16-20. Depending on cubes. I guess I should note around 6,000 rpm'sQuote:

With the YS, with the 3" I made 21lbs and with the 2.85 I made 24lbs.
What would i need for 10-12lbs?
8" lower, 3.3" upper just a guess. The key here is belt wrap. The internals are large and heavy, inertia can cause belt slippage. Thats what I would try if it were me and I wanted around 12lbs out of a YS.
Prbably and 8" & 3.33"Quote:

oh yeah, definitely. i know what speed and power i want, so i dont think a smaller blower could pull it off. i intend to use 25lbs by september.
With the stock 8" / 3.33" pullies my 20 pound boost gauge was pegged almost instantly..
I thought you were running the 8"/3" not the 3.33. Hmmm.Quote:
