I wish HP was that cheap. It's more like $20-$30 per HP on the very low end and then starts going up and up the more power you are making.

Do you have the belt sizes you used for the 25% underdrive crank pulley? Thanks!

For the PowerBond PBU1117SS25 25% underdrive pulley I ended up using a 42.0" (stock 43.5") A/C belt and 70.3" (stock 72.5") main belt.

Sorry, just now seeing this. I used 42" for the AC and 75.16" for the main belt.
