I appreciate you following my build and with it helping you with your build. I almost wonder if your OEM tensioner might be maxed out due to the belt being too tight and isn't taking up the slack anymore or if the tensioner got damaged for the same reason. Before I switched over to Topgunz's tensioner pulley, I was using another fabricators set up which ended up damaging 2 idler pulleys and my OEM tensioner due to my tensioner being maxed out.

I never sent any RPM belts with the ACE kit. I do however send them with the Rotrex. Turns out the RPM belts actually have a big variance in length over the standard belts, even if they have the same number/length. On the Rotrex kits the RPM belt on the supercharger will have a ton of clearance and can be placed on without even touching a pulley. The regular 10 rib belt needs to be rolled on and is a challenge. Theres like over an inch of difference.

If you run the setup I sent with the ACE kit then the idler should be on the bottom with the K071065.

If your shop changed that and moved the idler to the top then your belt should be the K071045

I am unsure what size your silver pulley is. I am guessing they also changed this and thats why your boost is so low. The ACE kit will consistently make 14-15psi with the setup I send. You should go measure that pulley.

So I measured across the face of the silver pulley and it appears to be 2.75 in. in diameter. I also noticed that in the install instructions there seems to be a silver pulley as you can see in the pic and in the pic later in the instructions it shows a black pulley. Not sure if you switched pulleys at some point during an upgrade of this kit. I'm wondering if my OEM tensioner pulley needs to be replaced but I also see that Redondoaveb had mentioned that you may have a different tensioner pulley available?

I also plan on getting the K071065 belt and put the idler back to the bottom position.

Topgunz doesn't have a different tensioner pulley available that I'm aware of. I did mention the OEM tensioner. Not sure if that's where you might have mistaken it as me saying a different tensioner pulley. The silver pulley should be a 2.87", that's the 9lb pulley. 2.75" I believe would be a 10lb (Aaron can verify that). I assume his kit was shipped with the 9lb (2.87).

I just measured the pulley again with a digital micrometer and it is 2.74". I'm beginning to believe that the kit may have come with the wrong pulley. I did order a new Oem tensioner as well.

That's interesting. Maybe they came with the 10lb pulley. What belt # is on there?

There's a chance the incorrect pulley got put on and I never caught it. When those ace kits went on sale it was a tidal wave.

Let's get you figured out bud. I'll send you a "9psi" pulley that comes with the kits that are 2.85". I'll also send you a new K071065 belt. All on me. Just move that pulley back down to that position on the bottom.

PM or call me and I'll explain how to remove it easily so you don't have to take it to a shop.

Not sure what belt is on there now. Couldn't get it to stop in a place that I can see the numbers. I guess I'll find out when I take it off. What I do know is that the idler pulley was in the correct spot, with the correct belt upon the initial installation. When I brought it back in for the first 2500 mile service I was noticing boost loss. At that time, they (RT Tuning) said the belt was slipping and changed out the belt. At that same time, they must have had to move the idler pulley in order to install the new belt. I'm gonna reach out to RT Tuning tomorrow to verify.

I'm guessing they only had the K071045 in stock and knew they could move that pulley up to make it work. That's the belt that comes with the stillen kit so I'm sure they had some on hand but the K071065 is selective to the ACE kit and Rotrex.

Certainly nothing wrong with the K071045 belt and the pulley in the upper position as long as the 9lb pulley is installed. That was my set up and I never had any belt slip on the serpentine side.

Just a heads up: The Gates K080220RPM belts are getting hard to come by, every single "proper" distributor is out of stock and the only place to get them is a couple sellers on ebay. I bought a couple to hopefully hold me over until a new batch can be produced and everything is restocked.

I always kept a couple spares for that same reason
