I've done some research on here for a while (been a lurker for probably a couple of years before I finally joined) and it sounds like a good basis for pulleys on a prepared class with a 700 is with 6" to 4" or 8" to 5". I was pondering why not go larger diameter, yet maintain the overdrive ratio? Like 9" to 5" or 6", or 10" to 6"? The one reason I thought of this would be more area for the belt to grip, but I take it that with the sizes already ran, that going larger might cause clearance issues under the frame, and if I had belt slippage, that's going to be more of a tension issue?
The second thing I was pondering was side-to-side location of the 700. If the motor and trans are straight back from each other(sans clutch and idler(s)) the belt basically sits in a teardrop shape, and in terms of degrees of rotation, the motor side would be over 180 and the trans would be under. I figure after accounting for the clutch, it will bring the belt in closer towards the trans pulley on that sside. So I was thinking would it help if the 700 was offset to the side of the chassis opposite the clutch, to try and increase the amount of belt contact on the pulley. Once again, this might just be more of a tension issue.
I'm pretty sure I'm over thinking this, but they say the only dumb question is the one not asked.
If my second question is hard to visualize, I will try to get a picture up later today to help with what I am asking.
