Hey Guys...I recently installed a Kenne Bell 2.2L blower and finally got everything buttoned up, including my baseline tune. Started it up, idles great but the belt tensioner that came with the kit bounces while the motor is idling, therefore I believe I need a new one, however the KB manual doesnt specify the actual part # for the tensioner and I dont even know where to start looking, help me figure this out so I can finally get dyno tuned!!! Hoping somebody has dealt with this before, I searched and the only info I could find on KB tensioners was kbracings thread and he has a whole different blower...I apologize for the chitty cell phone pics...

 

How much does it bounce? I am trying to remember how the tensioner attaches to the mount plate on that kit, single bolt and does the tensioner have a locator pin going into mount plate? Looks similar to a HD tensioner.

 

Quite a bit of bounce, enough that it was the first thing I noticed and I've never seen a tensioner move this much before, it is single bolt, but it was attached to the plate when I got the kit, so I am not 100% sure on how it mounts exactly, it is the same kit you used to run! Know the part # for a HD tensioner so I can check em out?

 

I think the maggy he tensioner mounts like that but don't quote me, I don't own one and I'm not 100% sure. Looks almost like the tensioner on my 91 camaro.

 

You have a PM, if you get any measurements off of it to compare I have a Magnacharger HD tensioner that I can help you compare them.

 

Thanks guys, I will try to get some measurements tonight...

 

Take it off and see if there is a indexing pin on back.

 

Pulley diameter looks about 3" (77MM). The length from pivot center to idler center is 2.75" (70MM)...

 

Fawk...I'll head back down there after work, didnt even think of that earlier on lunch break...

 

Also measure the depth, from front face to mounting surface.
