Ultimax vs G FORCE BELT

[DMCTurbo]

These belts spin at whatever RPM, crazy stress on them, heat cycles etc... yet you can't fold it up to put it in the trunk bag. Not saying you guys are incorrect but sure find it hard to believe.

Me too.....I read it on gates own site. It's Pretty clear.
Search "G Force belt"

The medium bag will hold a belt nicely.

Yep, mid sized bag holds the belt in a circle.

That's what I have but the belt doesn't fit straight lengthwise. I'm really not that concerned, it's just funny I learned something new today about the belt I've been using and storing for years....lol

I have the medium bag and the belt fits snugly without folding backwards.

So far have never needed to install a spare belt so only need the spare for emergency to get home...8JP will work for that.

Hmmmmmm ...... DMC stores his belts folded up, and he does over 140 mph in the Quarter Mile. I think I'll start storing mine folded up too. Maybe I'll go faster?? Lol

I didn't know how to follow up on his comment....thanks, fleecer. Lol.

Another vote for Ultimax. 3,500-4,000 miles per belt on my MS16 tuned SW. 8JP would last 1,000 miles with the same clutching.

All depends on the brand of belt and the compound. Like I said, I've seen it myself with the Dayco XTX belts, bend it backwards and the cogs break right out of it just a few years back. My bud told me that back in 2014 or so and I couldn't believe it. On the doo, you store it on the clutch guard, so it has to bend backwards a bit, just installing it on the holder would break the cogs out of it. First time I've seen it happen myself. Brand new zero mile belts mind you.

I had a new Timken Ultimax XS crack as it was held in the secondary with the spring pressure taking it off in what I would consider in a normal removal manner too. To me, the XS seems very fragile that way, so now I treat them with kid gloves installing and removing them if you know what I mean. The 8JP it seems is not fragile at all that way. Seems like some of the others are however, like the XS and the Redline.

Thanks for this Bob. Good read!

Lol can't wait to see how fast I can go on an unfolded belt.

I truly believe the XS belt quality has diminished over the past couple years.

I find it a bit surprising. But looking at that sheet..

All of the below graphics basically are saying that there is a minimum curve radius around which the belt is designed to operate. It isn't about normal vs backward bends, its about minimum bend radius. The 2nd (do not crimp) and 3rd graphic images (minimum distance) are both describing minimum radius issues, but in the normal bending direction, not backwards bends (1st graphic). These belts are designed around minimum stretch fibers (carbon/kelvar/whatever) which when subjected to less than (tighter than) normal curvature is either stressing the fibers themselves or the interface between the fibers and the rest of the belt material resulting in an overall weakening of the belt.

Timken bought Carlisle (original maker of XS belt) in 2015. Wonder if Timken's bean counters put pressure on to reduce cost?
