Primary spring for OVS turbo

[flatlandsledder]

07 M8 Tial. It has the secondary conversion. The primary spring is black with green stripe. I think the primary spring was part of the OVS clutching. At least I hope so. It seems to engauge very high. Around 4500? Anyone familiar with this spring? Thanks

that should be a polaris spring 120/340 that's what they sent us for our 8. ours comes in nice and soft 3k or so no track spin on engagement.

Same issue with mine running the same black/green spring, engages too high at 4500rpm causing track spin mostly at lower altitudes. Doesn't seem to bother me as much 6-7000ft, but probably would lower mine a bit closer to high 3000's as well. It is an OVS clutching setup.

That is a Speedwerx spring 190/330 if you what to lower the engagment get a low rate spring on the starting rate of the spring.
