Tight Belt is Important!

[Posi]

All I got to say is I had belt slip with mine and the tensioner should've done its job by what is being said in here. Good tension, tight belt,...... Then we went shorter and bam. Fixed! I guess we all need the Reichard one then.

And just for the record I'm running a Whipple with a 3.5 upper and a 90mm idler to go along with it. You'd think that'd be plenty of belt wrap.

most people notch the tensioner which allows more force on the belt from the tensioner which is where people run into these issues with bearings going etc.

Yeah there is slightly more tension when opened beyond the notch, but it's not like night and day difference. I hardly think it's the kind of pressure to wear out bearings.

Great... more sh!t to buy! Just curious, is the 3.5 upper non-slip?

I'm guessing that the tension will be greater with the spring compressed further.
Typically springs have a cumulative pounds per inch thing going on.

Probably not because it's the one that came with the Whipple.:lol1:


And I'm with you Jimmy on your thoughts for the spring.

And I'm with you Jimmy on your thoughts for the spring.

I am as well, i'm just curious as to how anyone could think that would not be the case.

 

[jm@ReischePerf]

Well I agree with all of you but they could be using something like an elliptical cam to make the force more constant througout the range of motion.

For anyone who was following this thread, I did some torque measurements on the tensioner in here:

Doesn't the tensioner need room to move under load situations? Mine was notched for that very purpose......

Observe the tensioner when you stab the throttle, it actually closes more to take up the slack from the belt stretching under load.

True. Brain fart.......

And remember,

If you're over 65, you're on medicare, and you have diabeetus, you may qualify for a free belt and tensioner from Liberty Medical! Check your belt tension and check it often!
