2000 centerspring Elite S trans.

Is a 2000 center spring too stiff? Will it lead to a broken rear driven face? I am currently running a 1500 and i noticed running it on the stand with 3000 rpm grabbers the rear driven face is already starting starting to open berfore the clutch even engages. I would like to improve my takeoff but i dont want to destroy parts in the process. thanks

Greetings:

Swap the clutch springs for softer or drop a few grams from the variator. You're starting off in 2nd gear.

Does the variator and the rear driven face "shift" at the same time? Meaning if the rear is opening up does that automatically mean that the variator is shifting as well? Or can the variator and driven face be tuned so the driven face opens completely then the variator will start to move.

Both operate together at same time.

If the rear pulley seperated and variator didn't come together at the same instant, the belt would have a ton of slack and slap or break on the case.

Ok thanks im getting a better understanding now.

So they both start moving at the same time. But once the rear driven face is completely open does the belt continue so ride up a little more on the variator? (i realize this would only happen if there is enough slack in the belt)

as well, once you put in a stiffer center spring you will need heavier rollers to help open up the driven face? correct?

What im getting at is whats the purpose of going to a stiffer center spring? If one can just change variator weights for the same effect.

The only thing i can think of is the center spring helps pull the belt lower on the variator when rpms are falling due to climbing a hill for example. And the weights in the variator are better used on acceleration using certrifical force to drive the rear driven face open.

How does the stiffer center spring help?

that is exactly how i have thought about it. but the two have to be set up properly to balance each other out.
