Then it sounds like they don't make it currently. If there was one 1/2" up or down, you maybe able to use that depending on your tension situation, but they are 1"+ off so looks like you are stuck with a normal belt for now, not that is a bad thing.

I have the updated A&A procharger bracket. Just trying to order the right ones since TX2K is so close.

There is no K100935RPM, the only things they have right now are well beyond that range. Once you do the pulley swap, reuse the old belt for the time being and with it running check the tensioner. If it appears to be near either end of travel you will need to adjust belt length.

@Unreal; The RPM belt is going to take the abuse better than any belt out there. Where a polyester corded belt stretches, the aramid RPM won't. A polyeter cord can only stretch so many times before it lets go. Every time it stretches there is a little bit of slip and heat generated. As we all know heat and slip kill belts. On street driven cars that see redline occasionally, this might not be an issue of immediate concern. On track oriented car, with sustained heavy loads, this will be noticed immediately.

The aramid cord coupled with the dual adhesion gum layers creates a belt that wont have the dreaded belt slap at certain frequencies. This will manifest itself as broken tensioners, belts even idler pullies.

GM has superseded ALL of their LT4 and LSA supercharger belts to aramid cord from the factory. They didn't do that to save costs, I can tell you that. What they don't have is the stickier rubber, dual adhesion gum layers or sizing for aftermarket blowers and pulley setups that the RPM line offers.

This is all from my conversations with Gates

K080514 is what i need in a gates v series belt, what would be the equivalent in a rpm series?

ZincGT

These 2 are the closest

K080507RPM K08 1 3/32” x 51 1/4” - Black 8 50.748 Outside Circumference 51.25
K080525RPM K08 1 3/32” x 53 1/8” - Black 8 52.6 Outside Circumference 53.169

Rock auto seems to have the best selection of these belts at somewhat reasonable prices for anyone that is looking

dave at superchargers online

Chad and Drew are the reps for the RPM line and are based here in Colorado, I've used these belts on a couple different cars with good success

Are they keeping these belts in stock?

ZincGT

They ship from Gates

You can't beat $45.00 @ Rockauto. They usually say it takes 5 days to get them, but they typically ship them out in 2-3 working days. I've ordered 3 RPM belts from them so far.

Now that is just about the coolest thing I've seen ever since I started buying car parts - a manufacturer that asks you to tell them what you want and they will make it for you!
