If we refer to it in reference to load it becomes a little clearer. 0% load would be a tensioner with no belt on it whereas 100% load is a tensioner with a ratchet on it with the internal spring wound up tight.
RPM belts aren't going to stretch so it's imperative that a belt length is chosen...
Were you using a green HD belt? It seems like you terminator guys have issues with squeaking quite a bit with those. It's most likely due to the green back combined with the specific pulley configuration on that engine.
What size/part number were you using?
First thing you'll want to do is verify where the tensioner rests with your current belt; you will want it at 50% load or less.
As you know, many times a shorter belt is chosen so that even when it stretches, the tensioner won't fully extend and some tension is maintained.
Not necessary with...
It looks like the longest we have right now in an 8 rib is a 108.8.
I'll look at getting longer belts added but please remember; when switching to an RPM belt you want to err on the longer side.
What are some actual sizes you guys are using?
Your belt slippage is due to the polyester cord stretching out when it heats up. This is a characteristic of polyester which is found in 99% of the belts on the market. Gates has recently introduced our line of aramid (Kevlar) cord RPM which will not stretch. By the time your belt snaps or you...
Thanks Intervention!
Our RPM line of belts was engineered as a no compromise belt for supercharged and high horsepower applications. They feature an aramid (Kevlar) tensile cord, two layers of adhesion gum and come in tons of sizes for aftermarket (and stock) blower setups.
