Uhhh.... Roush? At least call them and get the size if you can't read the numbers on your current one.

DiMora, is there a 6 rib gates belt in 133” length? Thank you.

You don't have an belt adjuster on your TVS? I'm not familiar with the belt routing on a Roush though I do know the alternator gets moved, but I have a little pulley on as slot that can give me up to 1"-2" of belt length adjustment. Whipple. Is that unique to the Whipple set up? I would think it would be incorporated into any belt driven SC, but I assume a lot.

You can always just cut 2 ribs off an 8 rib...

The story I got was the Roush 6 rib belts are actually 8 rib belts...with 2 ribs cut off. They flip the 8 rib belt inside out, then place it over a mandrel and slice 2 ribs off.

The roush HD tensioner, should allow for a tiny bit of wiggle room, but only a tiny bit. Having one or more idlers /alternator mounted on a slotS would be a good fix ..... provided it didn't shift in the slot. That's one helluva lot of tension on a belt. A separate 2nd or 3rd hole, on a bracket for an idler would eliminate any bolt-slot slippage problems.

If he's talking about the Whipple set up I think he his, I have the same style on my 04. I switched the normal snub idler for it. It's an awesome piece. It's already saved me money on belts. And it's pretty stout. I have yet to hear about one slipping.

If your running the 4” Roush pulley on your TVS then the belt should be R07020041-13-AA.
If you have upgraded to the 3.5” pulley you would use the same belt and replace one of the idlers with larger 90mm version.

In the picture below you can see the small pulley between the SC and the alternator. That is my belt adjustment pulley.


And in the upper right you can see the bottom of the pulley and the 1"-2" slot it maneuvers in. I've never had a problem with the adjustment changing, never had it slip. And I use a thump racing tensioner and have it set pretty deep in its travel so there is quite a bit of tension on it. The force of tension is not in line with the slot so that might help it hold better. But like I said, never had an issues with it and it gives you quite a bit of adjust ability in belt length.
