Doo turbo clutching

[Turbo11T]

Just getting done building my 583 turbo sled. Just wondering what setup up ski doo turbo guys have in the clutch. Heavier pin? Special ramps? Steep helix? I figure the turbo 670 clutching would probally be close enough to get started. If someone who has had a good setup please share with me.

Thanks

Over the years ive spent messing with helixs, ramps, pin weight, springs, ramps, gear ratios ive learned a few things. Gear up a little bit from stock, run sum what agressive helixs, a spring that you like, and Thundershift arms. With those arms you can make just about any spring, helix, ramps work the way you want them to. You can add weight to where its needed to control the power of boost. (within reason of course). Hope this helps ya.

I was thinking those arms would be a good deal on a doo turbo.
