Turbo rx1 clutching for 25 psi

I think the RX and Apex had the same helix , a 51/43

So all this talk about purple spring for secondary , what part number should I order . I'm also gonna order the white epi tra spring for my stm rage 8 primary to try out . What at your thoughts on this clutching setup . Thanks

Just buy the yamaha part # then you don't have any cat parts on your sled. Sorry I don't know the STM setup. I keep it under 20lbs with a yamaha primary.

Had real good luck on snow with a purple EPI secondary spring and stock RX1 helix...

What was your spring wrap with this spring . Thanks . Have one now .

Try 0-2 first, then 0-3

I went 0-3 . Any difference from 0-2 . Few more things to do then I’m taking it out to test . Finished installing 285 chisels on it . Went midmount header now with a machined 2860 turbo with billet 3071 impeller. Lots of new changes .
