Do you defeat some of the gains of changing the helix when you install a spring with a higher compression force to keep the belt from slipping in the clutch?

Like going from a 36* helix & silver spring, to a 45-36* helix & silver/blue spring.

The two springs have the same radial tension, But the silver/blue has higer compression force.

So if you have a higher angle for faster upshift and a spring pushing harder to keep the sheaves closed, (to keep belt from slipping) What have gained from the change??

Just wondering.

GJR, as you go from the 36 to the 45-36 the stiffer spring is usually added to stop belt slip.  If your motor can pull its RPM through the range with the stock spring fine but it may not backshift as well.  And yes you are right when you say the two shouldn't work against each other and that is what happens if you don't test correctly.  It just waists power transfer if clutches aren't set properly.  When the secondary is fully shifted and you are at the overdrive ratio the belt doesn't really need alot of side force anyhow. I tried a T-1 in my old XCR, geared down one and man that was fun. All it took was some experimenting.
