VMP TVS Pulley question/issue

[2011 gtcs]

So I installed a VMP 2.5 pulley when I did my TVS swap, well the pulley is shorter the blower snout i'm not sure if this is normally how its supposed to look or if its supposed to be pressed on more.

The reason i'm asking is this morning I heard a belt squeak for a couple seconds :fm: than it went away, it happened one more time and that was it I haven't heard it since. So I atleast wanted to make sure the pulley looks correct, maybe I can adjust the Metco idler so the belt is tighter.

Did the pulley and blower snout flush? I know the instruction say to make sure snout and pulley are flush.

I can't really tell from the picture, did pulley line up with the rest?

Also, if you still got old pulley, see if you can measure it and take side by side photo

the pulley is flush with the snout, I have a 2.385 pulley on the way, I will compare the too once it comes in, sorry for the bad
What do you guys like better the Metco Idler kit or the 90mm idler, or are you guys using both.

mine looked like that also with the Billet Pro 2.5 pulley.
never had any problems with it.

As long as blower pulley line up with rest of pulleys. You are good.

I think if you have the metco aux idler, you don't need 90mm. Or 90mm idler, no need of metco. It's also depends on the belt length in the end. If you use both, the stock belt may not be long enough.

You can go slightly past flush if you want to try it. There's a slight lip inside so you won't go too far unless you really rack on it.

Same belt?

Does it look like the belt is riding straight or trying to move backward? My guess is straight.

You do NOT want to use a Metco adjustable and a 90. One or the other. Don't over tighten the Metco. This pulley won't slip. I'd even suggest LOOSENING the Metco one notch.

Interesting. I drove my car to work this morning after having installed a TVS with 2.4 pulley at the weekend. At the weekend it sounded fine, but now the belt is noisy on startup and at lower speeds. When I reach 60 it goes away and once the motor is warmed up I never hear it again at any speed. I'm using the original belt and thought maybe it was very slightly too long. Pulley is flush with the snout and looks like it is running true.

When I did the TVS swap I replaced the blower belt with a new ford stock one so I wouldn't think the belt would be the one squeaking. I started It up this morning and the noise was worse so I left it home and drove my truck to work, I'm thinking it could be the metco idler pulley making the noise, I will pull the belt off when I get home and let you guys know what I find.

I ordered a shorter one from VMP.

Almost guarantee its the aux idler pulley

Why not both?

Why not both?

First of all.... Why?

Keep it simple.

Well I found the problem, one of the lower ford idlers near the A/C compressor had failed. With the pulley tight I could wiggle it side to side, all the other pulleys seem ok, here are some pics, tell me what you guys think,

I will order a new one tomorrow and hope that fixes it.

Almost guarantee its the aux idler pulley

My money is on the blower pulley itself, had the same issue with my 2.59 originally until I found the sweet spot.

 

[frederick184]

Fitted a shorter belt today and it cured my slipping problem. I have VMP/2.4 pulley/90mm idler/stock lower

Belt had a glazed finish so looked like it had been slipping for a while. Now it is quiet and it holds boost no problem.

From what I remember with my 08 gt500 I left the pulley flush with the blower and everything was perfect.

Regarding OP's issue, that pulley looks like its for the stock M122. The TVS pulley is longer.

The first picture looks as if the pulley needs to go back onto the shaft more. I used the 90mm idler on mine and had a tough time getting the pulley on right. It was flush on the snout but on too far (not enough clearance in the rear). Once I pulled it up a little on the shaft it was good. It's not flush with the shaft, but it runs true with no noise.

Is the edge of the belt frayed? When mine was not lined up the edge of the belt would fray a little.
