Well its in my truck which is at the shop. Its about a 100 mile round trip but I could possibly go late next week?
This is all great information for somebody that has pushed one hard. I know the mod motor guys with the roots blowers run like a 3v tensioner which is an upgrade over the 2v and 4v stuff. They also run a pull super close to the blower pulley to add a ton a belt wrap. An Eaton with a 2.76 upper ends up having like 80% belt wrap. I see no reason why we can't do something similar with a centrifugal.Would like to add my thoughts. I was maxing out a Novi 2000 and was consistently running into issues with throwing belts. Alignment wasn't an issue as I would use a long level to make sure. The problem is the amount of side load on the "powerdyne style" bracket. It likes to flex alot under load. My immediate opinion is to make the bracket out of 3/4" plate instead of 1/2". The little A/C helper bracket in my opinion does very little. I made one for my blower and it didn't do much. I had to make a halo bracket that went around my blower and then used a turnbuckle that bolted to my intake. I was able to adjust alignment like that once I had belt stupid tight... And that is the problem too. We really need a super duty auto tensioner.. without one I think we are chasing our tails. Stationary tensioners are garbage if trying to spin blower to it's max. if I was doing it all over with max performance in mind I would first use 3/4" plate. Then drill the pattern for a procharger so I can use larger diameter pullies due to the steeper internal gearing. After that a auto tensioning system would be an absolute must. And for racing only I would round it off with griptec pullies. These are just my opinions after trying to spin a NOVI to the moon lol.

Well I have yet to throw a belt with the turbo lol. But honestly if I went to a built motor I would consider a big procharger.Which realistically belts are supposed to just be used for holding pants up anyways

Fusion 360 is easier and there are a ton of free videos on YouTube.I have an acrylic pattern that Keith Blackburn loaned to me for a Novi when I was going to try to use my X-Carve to make a bracket. If Keith doesn't mind I can send it to you to copy, I had been trying to transfer it to a CAD drawing, but I am a noob at Solidworks and it is taking me forever

I've used it, but my subscription expired and they want a TON of money to renew! I found that with a membership to EAA (eaa.org) you can get Solidworks for cheap!
Very nice, after this summer of being held captive by the heat A/C is def on my list!
