this may take a while but here goes.please correct me where im wrong and feel free to add to this.
for top speed and economy you want the secondary pressure to be as little as possible without slipping the belt
the lesser the angle the more side pressure applied to the belt via the sheaves.
you need more sheave pressure for low speed than at 1:1 or overdrive, some where in the neighbourhood of 2:1.
not taking into acoount the helix does the secondary spring maintain an even pressure on the belt as it is compressed?if so why do a lot of people run a finish angle of say 40 or 44 degrees would this not add more side pressure to the belt and cause loss of performance on top end?
this may answer my last ? but i need someone to verify. since the secondary senses torque; by running the belt pressure too light(too steep of a finish angle say 50 instead of 40)) near full shift could this prevent the secondary from opening up all the way into overdrive?
