Drive Clutch Options for Top End

[culli292]

So after discovering my Carryall 472 has 15:1 gears and no other gear sets fit, I am looking to see if any drive clutch options exist that will get me more top end. Cart has a clockwise rotation with 22 HP Predator. I figured if I could get a larger diameter drive clutch I might be able to get more top speed. I have so much torque its ridiculous! Any ideas what drive clutch might work to give more top end speed?

You'll want an 8" clutch if you can find one. CPP has one that's been tested and tuned for big block golf carts. I've never used it, mostly due to the size, it wouldn't fit in my Yamaha G1 frame.

I saw that and considered it but would need a rear clutch that accommodates a wider belt too. Wasn’t sure if buying both clutches and new belt, $800 would gain much more top end? I’ve attached a photo of the cart in case anyone was curious what I’m working on. It’s quite the beast, just needs more top end. Currently it’d be an amazing hunting rig but I plan to use on roads too.
