i got the 2003 epi catalog and there is a red secondary clutch spring. it is stronger than the black spring. does anyone have one? this spring should make the belt last even longer? can the belt be squeezed to much?
thanks


black 2-1/2 load 115lbs 1-1/4 load 220lbs

red 2-1/2 load 237lbs 1-1/4 load 326lbs

 

Absolutely it can be squeezed to much, but whether that red driven spring is too much or not remains to be seen. I am sure they developed it for some specific purpose. Maybe it was needed by the people that do sled pulls.

I haven't slipped once with the black one. My RPM's are high enuff for my tastes, so I won't be anxious to try out another spring.

I am sure EPI did research and testing on it. The funny thing is that spring shows up without any real advice on whether to use it or not.

Just gimme that computerized distributorless ignition module from Emerald F and I will be fine.

 

The red secondary works VERY nicely in the 360's... and is what they (EPI) recommend when you call them. The black is near the same as the stock 360 secondary spring (I think they said the black was a little less stout than the stock if I remember correctly). Since putting mine on I've only smoked one belt (and that was definitely MY fault, not the quad or anything else.)
