Idler qualms

[KTs03]

Ok, anyone who was at the march Mokena get together and remembers Dan installing the 2.80 pulley on my car might remember the issue with the RPM/Motoblue 100mm idler that was installed along with it. The issue was this:

The RPM idler bracket did not appear to be machined correctly and the belt rode along the inside edge of the pulley instead of lining up in the middle.

I drove the car for about 3000 miles since then and haven't had a problem yet. However, to prevent one in the future I went ahead and bought the 100mm upper idler and bracket from billetflow. Attached are some pictures after I installed the billetflow idler and bracket. The first picture isn't anything special, just to show that it is the billetflow setup. After looking at the side view you can see that I'm dealing with the same issue again. The third picture is of the 2.5" idler below the upper 100mm idler and as you can see the belt rides along the inside edge of that pulley too. I'm thinking maybe it was the upper 2.8" pulley that was made wrong.

If you want to swap pulleys again, I'm sure we can hunt up a similar sized pulley to fit onto the blower and see how that one lines up. I think Mike, "Get Ready", has one sitting around we could borrow for a couple of days.
Let me know.

Just a thought could the aluminum bracket that allows the pullys to be mounted be warped? Was this car bought new-Been in a front end collision? When we were at Bowling Green last year there was a car that had the same problem and the aluminum mount on the engine was cracked. Probably not it but just asking

I bought the car new and it hasn't been in any kind of collision. There's been at least two other people that I know of that had the same problem with the RPM setup.
