Stronger belt

[SideHogger]

Ultamax xs825 never blown a belt from new with 8k. It’s been tuned from Hurricane 300hp for 5k not blown a belt ran back to back runs several times 132 gps. So I’m sticking to what works for me.

Yes, would you share your clutch setup?

I talked to application engineers at Dayco and Gates separately. Both told me 225 degF is pretty much the end for today's belts. They said that is the temp when the bonding agents are affected to the point where they break down and the belt starts to come apart.
My chosen temps for my IR gage color changes are just temps I've chosen based on what the engineers told me. I felt below 170 was very acceptable. Over 170 should be a zone where one wants to know the belt is heating up. At 200 (which you should never see!) it's back off time. The belt I overheated in the multi-mile ditch last year came apart at 225. It actually got to about 235 degF but was already coming apart by then.
As I said, temp is only 1 component of belt failure. Most of the belts I've blown were only "warm" not hot. Tells me the load exceeded the strength of the belt.

I only have a laser heat gun but after back to back hard runs and rip off side cover I am seeing belt temps of about 150 degrees. I am going to assume from your post that is a very acceptable range?

You wont have any heat related belt issues at temps in the 150 range, plenty far away from the danger zone.

Thank you sir!
