looked the belt over and appears to be good still has some rub marks but nothing that i think will weaken it i dont think . anybody know of a electric water pump that will work for truck accessory belt with a procharger ?

 

If it's difficult to install the belt because the belt is THAT tight, then the belt is too short. You could still have problems if you don't address that.

 

Mine ripped the pulley off after I tig welded it. That was with the 8-rib at 23 psi on the d1sc.

It is a common problem when you go to the 8-rib set up.

Be sure to weld it on good. Mine obviously wasn't. Pulled the weld out of the water pump shaft!

 

holly crap!!how were you getting 23psi on a d1 ?what was your set up? i got a 3.4 on here right now.

 

ya.. id say that belt is toast LOL


^^+1 23 psi on a D1, thats nuts.

 

Spin the blower 106% with zero belt slip.

I haven't seen anyone's D1sc make that much boost before either, but my 3-bar MAP said otherwise. I was tuning in the 260 kpa region.

 

Isn't one of the guys that runs with Phantom doing over 20 lbs. on his D1?

 

Happened twice before I welded it on...all 3 times were w/ 6 rib set-up.

1st time was w/ the original factory WP and the P1SC after smaller pulley was installed and idlers were relocated for more belt wrap...also grenaded the P1SC on the same pass!
Quicksilverado had a spare stock belt at the track that day...I hammered the WP pulley back on, removed the broken P1SC, put the stock length belt on and drove it 2+ hrs home.

2nd time was w/ new WP and D1SC...
freezing cold at the track that day...heated up the pulley w/ a propane heater we had in a friends trailer and slid it back on...drove 2+ hrs home.
Next morning I opened the hood in the driveway...touched the pulley and it fell off.

3rd time was AFTER I welded the pulley on another new WP...on my way to work one morning...
this time the factory weld broke on the big school bell lookin' WP pulley...@ the threads.

After the 3rd time...I went w/ a new WP...welded on the pulley AND welded on several ribs across the front of the ProCharger bracket in an attempt to limit flex... it never happened again (knocking on wood as I hit 'submit reply')

 

what were you running as far as pulleys ? sizes/ ribs?


did you try any different brands of water pumps? looks like a couple different people make them . i wonder if any are better then others.

 

No...but new WP each time...not remans...
They all have pressed on pulleys...shouldn't make a difference on brand.
IMO...I believe that the flexing of the ProCharger's mounting bracket is what causes it.
