I wanted to up the boost on my gt but I can't even get my tensioner to stay intact at 5.5 lbs. The stock ford one lasted a good two weeks but it snapped in two. Then I went through an advanced auto one that lasted a day and two auto zone tensioners that each lasted a day before snapping in two (usually a WOT from 1st to 2nd). Any suggestions? Are there steel tensioners? Has anyone ever heard of this problem? And do you saleen series IV users have the stock ford tensioner or something else?

you only need to post this in one forum. people will see it. posting 2 times is a waste.
thanks tk for the info. BTW, if anyone is having the same problem I found that ford makes a steel tensioner thats about 145 dollars. Just google part number XR3Z-6B209-DB. It is basically a must for blown 96-99 mustangs as I've read in other forums.

wow i didnt even know about those tensioners. I bought a ford racing steel tensioner for 156 bucks. Do you think that Thump-rr's is all that great? I mean 385 dollars compared to 156 shipped is a big difference. It does say unbreakable but I'll bet the steel one is unbreakable in most situations also.

What is it worth NOT to break a tensioner while out cruisin' around on a Saturday night with your best girl?
I would say that $230 is a small price to pay if you would need to get your car towed otherwise
What I'd question is why a 300 RWHP is breaking ANY tensioners. That seems odd.
Personally, I'd check to make sure you're running the proper length belt. If you're running a belt that's too small it can cause things like this to happen.
