I was just wondering if anyone here with a Roush or Whipple supercharger had replaced their belt tensioner, specifically with the Thump Racing tensioner, P/N PM 1002-XX.

I have some belt slip and I've upgraded my idler pulleys and made sure everything is in good alignment, and now considering a new tensioner.

I'm also considering the MoSaleen idler pulley system, but I've heard it won't work with the 4" Whipple supercharger pulley.

Any input would be greatly appreciated.

 

No one?

 

Run Thump tensioners on both of my Shelby's, the stock Ford casting is an accident waiting to happen.
Have a 3" pulley on a 2.9 on the 11, and a 3.5" pulley on the 3.4 on the 14.
