Few quick back pedals and let us know if the belt stays on. If it doesn't did it snap the arm?

You are probably the only person in the world driving a Magnuson charged truck with that tensioner. Can't believe we can't get you to take one for the team. 
We know he Dayco unit doesn't fair well to spirited throttle inputs. Inquiring minds want to know how the Napa unit holds up.

It's actually been on there for awhile now and I do drive it pretty hard as much as go to the track but I havent had it on as long as the magnacharger tensioner but I have'nt back pedal'ed it like I did when I broke the magnacharger supplied tensioner either. Everyone has the part# now make this you're next tensioner. Sorry no testing here it's to damn exspensive cause I would have to buy 2 tensioner's 2 pulley's and probably 2 belt's for backup's so there go's $250 roughly I know I should quit

No worries guy. I was just teasing... This dang hobby cost enough without going out and trying to break things. My Dayco's broke at the return stops, snapped the arm. It doesn't look like that unit has those so it might fair better in a sudden belt lose.
I will never forget the Christmas day it took me 3 hours to drive the 10 miles home shutting the truck off long enough to let it cool down between 2 or 3 mile runs.
