I contacted Gates and the 'nice' short response I got after asking for a high performance timing belt, was:

I'd like a 'racing' timing belt just for some extra 'insurance'. A factory replacement timing belt from Gates (purchased on ebay if that matters but came in gates box and sealed, etc) already killed itself after a 20 min run on the highway. The rubber literally melted out of the belt leaving mainly just fibers all over the inside of my engine bay and left me on the side of the road. All was fine for 3-4k miles leading up to this but that was all back roads/4.30 gears. Took a crap soon after I put the 5.125 gears in.

Somthing aint right there. Even a elcheapo timing belt shouldn't self destruct in just a few miles. Better start checking for other problems, like gear / belt mesh or something rubbing on the belt.

It tracked straight for the first 3k ish miles, I was even under the hood the day it went and checked it and all was fine. I got on the highway for ~8 miles and the speedo was nearly pegged (30x9.5 tires, 5.125 gears with a 3spd auto). It was really revving out during the small 'trip'. I'm sure it didn't help that my radiator was 1/3 clogged with mud on the bottom and the temp got up to about 3/4 so I guess underhood temps could have been quite high and poor airflow and the day was low 90s...

None of that has, or should have, any impact on belt life - my suspicion at this point is your problem was an eBay "knockoff".

First off we are talking about a 1.6L engine right?
Did you check the #s on the belt to match it to your application?
Did you get a belt for a Samurai? did you remove the washer behind
the cog on the crank?
I would have to say you either got the wrong belt, or you have
removed a part that is needed to keep the belt aligned with the
timing cogs

what is this on? your hot rod motor you were building or a stock 1.6....or something else? that might help with diagnosis.
-
My 1.6l 16v when I put it together with the worked head.
Washer was reinstalled on the snout, keyway is in amazing condition, no groving/wear on the gears. Everything was fine with the stock belt, I just replaced it because it had 110k miles on it. The box said 1.6 16v and I compared it and it appeared the same.
-
Sounds like you checked everything like you were supposed to, I would
be contacting the Ebay seller and getting a refund or something.
There are differences between 1.3 and 1.6 belts, but the 16V is wider
and would be hard to not notice that it didn't fit right, the RPM should
of had no effect on the belt.
Was the tensioner OK and tightened? the lock nut tight and not just the
spring tension to keep it tight?
You might go get a belt (same brand) from an autoparts store, and take
back the junk one with the receipt and get a refund, or contact the maker
and see if they will honor it or if they want to see it for quality assurance.
Apart from there being another problem, like a seized cam or loss of oil to the
head I don't see this as being anything but a crappy belt or a forgery

You might also want to replace/clean up your tensioner pulley. I have seen on the 8 valve engines rubber on the pulley causing the belt to try and slide off. A quick sanding of the pulley fixed the problem.

The 'kit' came with belt and new tensioner... here's what was left of the 'belt' after my 20 min drive, nearly half of which was highway.

I starved the old head after installing the headgasket on wrong cutting flow to the cam, heated up the aluminum and melted the cam journals AND the cam.

How did the timing belt cover get that slot - was it cut by the belt?
If no - can you rule out the possibility of something getting in there and destroying the belt?
Looking at that belt, and the way the rubber backing has shredded away leaving the reinforcing fibre and the teeth, I really feel that the belt itself was either not the quality product you thought you were getting or else was new old stock and had deteriorated in stock.
-
I cut the slot to watch for any tracking, same with the ~1/2" hole for quick timing checks after my last rebuild cause I was paranoid about interference issues.
-
That looks like your new tensioner seized up and wore the back of the belt off.
Have you pulled it apart yet? You might want to tighten the tensioner without
a belt on it and see if it spins or not, I had a fan belt idler (91 Chevy p/u) do that
but I smelled a little bit of hot rubber and caught it before it destroyed the belt.

Looks like the belt has also cut through the timing cover, just above the tensioner. The belt rubbing on anything will heat it up and possibly cause all sorts of issues. The timing cover is warped, that is why the belt rubbed through it....get a new timing cover.

Looks like it to me too.

I don't think it is possible to put either a samurai or a trackick 8V belt on a 16V....they are both shorter.

Why not just get a factory suzuki belt? The original one lasted 110K miles. Probably not a better quality one out there.

I totally forgot about the height of the engines, :-[
