Wouldn't you get more wrap only on the crank? The head unit would still spin if there's less surface area and its being spun faster now

I don’t know why I said you can do a smaller head unit pulley, I meant larger to maintain the same blower rpm which will allow more surface to grip.

FWIW I had a Powerbond on my SC car and it was fine, a little heavier than stock. Stock was 8.8lbs and the Powerbond was 10.2lbs. I currently have the Romac Gold on my turbo car. It was a bit lighter than stock at 6.6lbs. It also works fine. Unless you are going full tilt it’s probably not worth the money for the Romac Gold vs the Powerbond but they do sell a less expensive Romac (Red I believe). That’s my 0.02.

Already have the powerbond that was linked above, I think I'll be alright for a couple years with that, once I can afford it which will be years down the road, I want to do an all out engine build like a dart block then I'll probably get the real fancy IW balancer and an internal balance crank.
