Bigger belt and drive clutch for more torque
hey guys,
So Ive been trying to figure out a way to increase my torque on my 05 carryall. I rebuilt the 350 a few months back, torque springs in drive and driven clutches, and converted it to a key start. However the drive clutch is now shot, grooved to hell and wont pull up hills. So I have some Yamaha clutches here that run a 1 3/16" belt that im thinking of throwing on there. My idea here would change ratios (like changing gears in a differential) so the larger belt wont fall as far down on the driven clutch causing the engine to spin more to move the driven clutch less (more torque). Much like when you increase rear diff gear ratios, say from 3.55 to 3.73, the engine has to spin 3.73 times for the axle to spin 1 rotation instead of only 3.55 times to spin once. In theory it should work, as long as the larger belt will fit into the driven clutch. 1 and 3/16" may be a bit too big, so im thinking of trying one at 1 and 1/16" or 1 1/8" which would actually cause more torque seeing as the belt then wont ride up the drive clutch as far, also increasing the ratio. Not to mention this would save me from buy or rebuilding the stock clutch. What do you guys think? Any thoughts?
