If you want the real fix you need a radius rod to prevent the braket from flexing. Flexing loosens the belt alowing slip.

 

I don't have an issue with belt slippage. Note in my setup the COBB Tuning idler pulley I have in place to increase belt wrap on the jackshaft ribbed belt:



I want the belt tensioner so I don't have to mess with jacking up the car and remove the splash shield from underneath whenever I need to adjust the serpentine belt.

I also want the belt tensioner so I don't over tighten the serpentine belt and wipe out the jackshaft, idler pulley, powersteering pump, and alternator bearings.

 

How much boost are you running?

 

Just 7.5 lbs.....

 

Once you get to 15+psi you will need something to prevent the bracket from flexing.

 

search ownz me...
what vehicle is that belt tensioner from ?

 

I'm running my car over 15 PSI with a non-revup belt setup and my TM variable belt mod and I've never experienced blower pulley slip. I'm also running a 3.12" pulley (one size down).

I believe the people who say the bracket flexes and the timrod setup is awesome and all, however, I've never had a problem, and I beat the crap out of my car, the bushings are old as heck and worn out, and I"m pushing a crap ton of boost and RPM's from the blower.

So, there it is. Just my experience, nothing more nothing less.
