Gates 38006
Steel Smooth/Backside 76mm x 17mm x 30.5mm
Its listed as a cross-reference for the 89003, and looks like it will actually give more room than the dayco pulley because it does not have the "guide" ridges on the ends of the pulley

I just put on the Gates 38006 after my 2nd shredded belt in less than 1k miles. It technically isn't any wider. The 26mm of the Dayco is the width of the mating surface. Including the ridged area its about 31mm, so the Gates is a smidge thinner. Also, the two things I like about it over the Dayco is that due to the design it sits further away from the SC itself and there is now plenty of clearance between it and the charge pipe.
My guess is Vortech chose the Dayco to save a few bucks. It's the only idler on the whole engine that has ridges so I'd say they are useless and are actually causing more issues than anything.
Anyways, I'll be the guinea pig for this one and report back if I have any issues. Also, I have the blue racing Gates belt on order but I will run the standard one I have on there now for an apples to apples to see if this is the fix. At the way my belts were popping it should only be a few weeks and I'll know.
