Have you straight edged the pulleys?

 

[allmotor65stang]

yes and its perfect..

My old side slinger got a rip or tear in the triangle that bolts to the head. Bottom side . Had to weld up the rip , problem solved.
That was the issue with belt throwing.

If there is not alot of wrap at the blower pulley they tend to fling off.

Is this a stick shift car ??

 

[allmotor65stang]

No 3 speed car. This issue just started to. Never had issues with belts flying off. Some times I would eat a belt but I fixed that issue with more preload and tighten the belt more.i had the belt to loose when i was eating the belts. The belt has about 3/4 twist and about 1" play up and down on the bottom side of the belt.

Is that adjustment hot or cold?

 

[Draw3D]

Check the idler pulley, it helps guide the belt.

 

[allmotor65stang]

Those adjustments are a hot setting

 

[allmotor65stang]

Also the belt is ridding in the middle of both pulleys. Maybe i need more preload. How much do some of you guys use ?

Watch the belt ride on the blower pulley and rev the motor. Does the belt track a certain direction?

yes it kind of tracks to the front of the car

 

[Mustangnut6788]

You have a belt alignment issue or something is flexing when the motor is revving. I fought the very same problem last year. I ended up putting a gear drive on it. I tried shimming the head unit to pitch the angle of the shaft but never had any luck. You could try that. Think belt sander, how you adjust the tracking on the front roller. I tried making an adjustable support like you have back to the strut tower but I was never able to get it right. I got frustrated and scrapped it all for a gear drive. Problem solved. As the other guy stated check your idler pulley too. If it is too far forward or backwards it can cause issues too.

Whats your radiator setup with the crank drive

 

[allmotor65stang]

How much did you get your crank drive for?

 

[Mustangnut6788]

Here is how I went about the radiators...

The gear drive is going to set you back about $3000
