offset between cat and polaris helix angles

[MBR46]

does anyone know the offset difference between the cat helixes and polaris button helixs? like a straight 42 polaris button would be a ....... cat helix?

I have a little info on this but a friend of mine does pulling with a polaris motor and tra primary cat secondary. I can ask he will know what to set you up with.

I remember reading that somewhere in one of Indy Dans post.
It seems to me like it was around 13 degrees.
42 poo button = 55 ac roller

yes it is a cat roller for the chain drive. thanks for the help. those polaris helixes are expensive to try just once and i have both secondarys
