Belt Life Highish Boost???

[Gobig510]

Honestly, what are you guys seeing for belt life running around 13 pounds of boost?? I think I got 200 miles on my last belt before it literally blew up, threw pieces everywhere, stock arctic cat 046 belt. I'm not using a belt cover because it was a little bent and would vibrate a little on top of the belt. Maybe I'm getting some snow on it? I don't smell any belt when I boondock, and am careful not to smoke it. I don't have any side vents, do these help that much? Is my clutching maybe just really messed up, or are you guys seeing similar belt life? Thanks...

I use my belt cover and have side vents. I change my belts voluntarily at about 600 miles ish. I run the stock 046 also. My clutching is the Cutler set up with the secondary torsional conversion.

The side vents really help get the heat out

Venting is HUGE on a high power sled.

M1000's saw nearly double the belt life after adding vents.

I have a vent in front of the clutches, side vents, and open lights or screens at the lights, and I get about 500-600.

Without vents... 200 or less seems about right at that kind of boost.


btw, you need to pay more attention to your belts with boost, blowing apart a belt could cause crank damage, try to pay attention to the little hitching you feel when a belt is starting to pull a cord.

Changed belts two times, each at about 500ish miles on a m8 running 10-12psi. They looked damn near new when I changed them. Side panels, shock tower vent also, I can't imagine ever running a turbo sled without a clutch cover. I remember what blown belts could do when my 1000 would gernade them, can't imagine how much crap they would rip out with some ponies behind it. Ovs's clutching setup.

no belt cover

haha, ya I haven't blown a belt with the clutch cover off, pieces were everywhere in my engine compartment, but didn't seem to cause any damage...
I'll purchase a venting kit, bend my clutch cover back to normal, and see what I can get out of this new belt.

Thanks

If I remember, you were fighting some clutching/performance issues in earlier posts. Maybe that is still a major part of your belt life issues.

As far as venting one very easy trick is to take a unibit to the back end of the side cover. You can bore a row of evenly spaced nice big holes from the top to the bottom on the back facing surface. Lots of air flow out...get the heat out. Cheap, nice looking, and very effective.

Good Luck!

I do the same but I use a 1/2 inch drill bit, when your belt starts pulling strings they start coming out the bottom holes. when you go to climb look down at the bottom holes and no strings your belt is probably still good

I wish I could get 500 miles out of a belt! I'm lucky to get 200 miles and if the snow is heavy its one day and I have dreads hanging off. Are all you guys running 162 track length? I am 2010 M8, 153 with 60/60 gearing, Cutler stage II 10lbs. The stock gearing was not working, wanted to shift right out. I have lots of venting on both sides. Dayco belts are standing up better than 046/060 and they warranty for one year.I was thinking about the engine brace mount - but $260.00.

remember when installing vents on the clutch side, make sure there are no gaps for snow to get in, moisture on clutches is pretty self explanitory! I usually run a very small bead of clear silicone to make sure if there are any gaps that they get sealed up!
