2021 Roush idler pulleys

[RoushRacer26]

I know this is probably a silly question but do all of the idler pulleys on the Roush supercharger have a spacer, standoff or something similar? Long story short I didn’t realize there was a notch in the front plate to access the tensioner pulley so I took the plate off. When I was putting it back on and the pulleys I could swear I heard a tink tink noise like metal falling down into the engine bay before I could get the idler pulley (the one next to the tensioner and basically below the supercharger pulley). I took a few pictures with my phone but it’s hard to see but I’ll try and send them. If I am missing a part will I need to buy a whole nother idler pulley or are there other options? Chances are im not gonna find a tiny piece of loose metal in the engine bay.

Yes they do, I bought a used kit and it didn't have the spacer.

I had to buy a full idler set just for that spacer... something like $200... insane.

Oh wow that is insane for a little piece of plastic! I decided to jack up the car the other day and sure enough there was a spacer sitting in the plastic tray under the engine.

My buddy has a lift and I have some Kooks LTH’s that I want to get on the vehicle before winter gets here. I currently just have the stock manifold going to a Roush X pipe hooked to the 4 tip Roush exhaust with active exhaust. It’s already crazy loud but I’m hoping that the headers will add some performance gains. The LTH’s are catless and I’m not sure how strict shops are about not meeting emissions standards so my buddy and I are just going to put them on in his shop hopefully next weekend so I was motivated to get that belt back on the car. I almost decided to go with an H pipe instead of the X pipe. The X pipe sounds good and I like it but I really like the deeper throaty sound of the H pipe.

cheers

You may find it's raspy without cats. I put high flow lth on mine with the stock exhaust and an H pipe and it was awful, made me cringe when I got on it.

I went with a 3" steeda cat back and it sounds really deep, almost old school muscle car sounding. Ironically it has an pipe.

I’m not a fan of the raspy sound so I guess we’ll have to see. I’m looking for more of an old school sound like it sounds like you have.
