Ok here is the placement of my front pulley guides. I hold it right up against the pulley without touching it. Tack the flanged nut in place. I do this to all three then remove the bolts and pulley and weld them on solid. This makes for a fast guide removale to change belts quickly if needed.
Here you see all three in place. Also you see a idler on the return side. This is more a guide to stop back lash when getting off the throttle at the end of the straights. it isn't tight against the belt you will see what i mean in up coming pics.
Here the belt is passing thru the idler. no pressure on it notice the depth of the belt. Now when the next three pics are up look at the depth with pressure on the belt.
Now notice with my finger slightly pushing on belt it sits deeper. So as you can see it is simply there to keep belt form whipping back and forth. The guide on this pulley is not as the others. I drilled a hole and tapped it for standard thread and run a flanged nut on a 1/4 inch bolt screw it into the frame and the flange nut is the jam nut to keep it from backing out.
