Also if the screws are too long they will bite the pulley gears and can put a sharp edge on them as well.Because the gears are such a small diameter you can screw them up over the edge of the pulley gear and as such will put a sharp edge on the aluminum gear too. So if your using long screws go back and check the pulley gears as well.

I am having the same issue. I'm certain that my rear belt is not touching the spur gear mount screw, as they do not protrude into the pulley at all. With all that said, I'm usually having to replace the rear belt each race day. It's just simply not holding up. Noticeable signs of delamination and shredding after the first run in open modified. I run the belt tension very firm. My only conclusion as to the cause of this, is due to the smaller pulley sizes on the '16 from the '15. The belt simply doesn't have enough wrap around the drive pulley(spur gear pulley) to keep it from skipping under load. Perhaps if the belt was wider, it would have a greater surface area on the pulley and wouldn't skip as often and increase longevity of the belt.

when i look at the belt alignment on the pulleys ,on my car the layshaft is out forcing the belts to rub on the shoulder making the belt thinner,i race 17.5 so its not the power causing the issue,dodgy layshaft mount maybe? ill see if loosening the layshaft screws and pushing the spur back and retighten,see if it helps

Both of my 16s have the belts running in the center of the diffs. Neither car build took any special massaging for masterful fit.
