I got on the truck a little the other day on a straight stretch of road to my neighborhood, part throttle but in boost (enough that the Nittos were fighting for traction) when power dropped off and I let out. Go to turn in the neighborhood... no power steering, voltmeter is at 12V and boost gauge doesn't go over 0 with a quick jab of the throttle. First impression is I tossed the belt. I have only thrown a belt on my KB setup once in the 4 years I have had it and that was due to a misaligned blower pulley. Well I get out, pop the hood and this is what I see...



Belt is a Dayco PolyRib and has been on the truck a little under 3 years. Other than being snapped in half, belt looks pretty good.



I checked the blower and all accs for binding which there was none. Are you supercharged guys (maggy, whipple, procharger, vortec, etc) snapping belts after only a few years use? I have had all my 8-rib swap parts for a few months, I guess it is time to install them. I will be running the Gates green HD belt with the new setup.

 

Good time to do the upgrade. Bummer on the belt pop though. Might check lightningrodder.com as most all of them use belt for boost.

 

I was puking belts like crazy.. Switched to a gates, have been running it for over a year now( cross fingers)

 

ha I can throw a belt and still have boost , sucks to hear ya broke a belt but give ya a good excuse to do the 8 rib now!

 

6 or 8 rib? When you switch to Gates, regular or HD?

 

I am running a gates HD with good luck so far. On my KB I used to run gatorbacks and never broke one. Changed them every year though

 

Gates HD, 6 rib.. That Procharger ate gator backs like candy

 

Dayco has served me well.

But i think its prob good practice to change belts every year. Its cheap insurance.

BTW your setup looks great!

 

Then stay tuned Tim as I plan to clean up some things with the acc drive and bracketry when I do the 8-rib swap.


I guess the belt served it's time given the amount of stress it had to endure. I did have it on there pretty tight to try and counter the belt slip I got when I put on the 3.25" pulley.
