absolutely no improvement over the 2 roller performance wise. tested on the very same sled same day on radar and timers. this was E.T. and MPH. so it might be better on belts, clutches etc. we say no performance gain at all.
I’m not surprised. If the 3 roller helix allowed us to use a softer spring, then I could see an improvement. It should be more durable for a very high hp application.
Frankly I would have just gone with a tied secondary. They shift more consistent when trail riding, and are easier on drive belts.
There are some world record Polaris speed run sleds that have Tieds on them.
