Here is what I've learned... take it for what it is worth.
Ultimax XS 809, I think. They are cheaper and come with a one year warranty.
I spoke with a factory tech from Carlisle about 2 hours ago... for about 20 minutes on their belts... although the XS 809 is admittedly a high quality belt they do not make a belt that is comparable to the Mitsuboshi 3211115 belts from Polaris. They are working on it though and hope to have a new design into the hands of some of the more hard core testers on turbos and NA PRO's this season... For possible release next.
The compound difference does make a diff in how it performs with the clutch calibration on your sled compared to a 3211115 belt. Also, the side clearance May need to be re-set.
Has anybody tried the Goodyear Gatorback belts? They might be a cheaper alternative but I don't know anybody that has tried them.
I have a few of these to try this season... I'm going to give a couple to my turbo buddies to see how they hold up.... I ran one for about 300 miles on a 900 last season and had decent results... BUT... the primary had to be re-shimmed.
There is another Polaris belt we can use, I'm researching now to find out. Never heard anyone use the AC belt.
$170 is probably the retail of that accessory. They do last a long time. Cheapest I think I paid was $130 through a dealer when I bought a machine.
The dealers are not making a big markup on the 3211115 belts... $130 probably represents cost or near it.
The 3211122 belt is similar to the 3211115 belt, but is cut rather than ground finish and is not as precise belt-to-belt in tolerance. JKinzer has had good results with the 122 belt. Similar compound.
you can run the 080 belt it is very similar. it is half the price. I would run only the 115 as i have never seen one actually explode. I feel that when belts blow it puts a lot of stress on the crank. Each to there own though.
The 3211080 belt IS
Similar as Jafraune points out...in size to the 3211115 belt, but not the same angle, compound or side width... Possible to use a temporary backup unless you set up the clutches... But you would need to buy another 3211115 belt if you did not re-shim and change weights... If your belt blows... I'd want the correct replacement "in the hole" for sure.
BREAK IN and washing is Crucial to belt performance these days.. a belt is something that you have to maintain, break in and keep in adjustment as it wears if you want decent life and wear.
Most riders that I've been around don't even have the belt deflection set on their sled... and this only takes 5 minutes. AND it makes a big diff in performance of your sled.
My 2 cents.
