I dont think the roes have too much of a slippage prob, but the paxtons do especially with the smaller upper pulleys, just not sure on the roes:dontknow:
Installed Stinker's 7" Lower Pully Today...
- Thread starter TNVIPER
- Start date
Hey Stink PM me the price of your pulley. I may go for 750 hp.

Depending on the weather/humidity...sometimes would hear some squeel from the belts........the dyno graph from the tune last summer also indicated some mild slipage...lines were slightly wavey....
I think Tony is correct...I don't recall slippage as a problem with the Roe. The seven band belt seems up to the job...I still have the initial belt...after about 18k miles.
Mine slips a little on deceleration. If I get on it (wot) and get off it right away, it slips momentarily. I've found a manual tensioner that would help with this that I will be installing during the build.

The belt I took off was the original Roe belt...has about 15K miles on it...the seam where the belt ends were stiched together were splitting...probably would have broke within a few thousand miles...you might inspect yours Prof..
Will do!
Thanks for the heads up.
Thanks for the heads up.
BTW..if you go with this pulley and have the Roe SC with the STANDARD Roe 5.6LB pulley (PSI with 7" pulley will be 11LB+) you will need this belt...

Thanks Larry:rock:
Hey Stinker... how much are you selling these for?? PM me if you'd like. Thanks

Running the 7" pulley ,will it have any effect on the rest of the components? Alt,A/C compressor,power steering pump or the water pump? (being that everything will be spinning faster,right?)

I have not noticed any difference in any other component...of course I have not ran AC lately.....

What do you think about longer term for bearing life on everything?
Yellow venom said:
I havent read anything that talks about premature wear related to the larger pulley. Using comparative reasoning I would think changing the pulley would not affect other parts any worse than changing the rear end gears from 4.10 to 4.56.
The engine will always turn faster at any given speed with the 4.56 thus turning all attached rotating parts faster. As far as I know Dodge did not change any pulley size (2004 vs 2005) when they went to the 4.56 rear in 2005. I have not seen any trend in bearing failure with the 2005s & 2006s..

So if you ran Stinkers 7" pulley and the 10lbs Roe pulley you will get 16lbs of boost?:dontknow: or am I missing something? If not 16lbs how much would you guess?
ttt.......
I honestly dont know bo, but i would think a good 12-14 psi would be possible, but after a bit I think the supercharger would be........out of airYellow venom said:
Yellow venom said:
16 LBs is what George said.......That assumes that boost increases at a constant rate based on pulley size......using calculius I could calculate this but there are variables to consider....PP heads lower boost #s...cam....intake restrictions.................:dontknow:
TNVIPER said:
I agree the calculation is difficult due to the differences between engines.
When Sean tuned my engine in the fall with the 10 lb pulley, he had difficulty getting the boost to where he thought it should be. Then he asked if I had any head work done, and I said no...but that my builder had done a little cleaning up and port matching last spring...and his eyes popped! Evidently the "clean-up" head work was some pretty extensive clean up and really increased the flow to the point that boost would not go past about 8 lbs due to increased flow...my error in not telling him...but very educational.
