Pulleys and Boost (Roe)

[tinygiants]

I have the smaller pulleys for the Roe. I bought all of the sizes that Kyle was offering. My target is 10 - 12 lbs.
I know if I put on the smallest pulley, I should be in the ball park.
Would I be better off using the larger bottom pulley and keeping the top one a little larger?
What combo are you guys running?

You should make a bit more boost than I am if you use Tony's lower and the 10# upper... somethings not quite right with mine. I believe Larry is at 9-10psi with the stock blower pulley, and the 7in lower from Tony.

I'm running the stock ROE pulley and Stinkers 7" crank pulley( a very nice shiney aluminum one too I may add-Thanks again Stinker) and it should be around 11PSI.

I bought the idler pulley from NAPA..Part # 38042. This replaces the top idler pulley next to the alternator.

The belt you want is the Goodyear Gatorback 7070950.......below is a link to Summit..
