pulley sizes/boost levels

[jokerj280]

Hey guys...got one for you.

i have a YS (obviously) that i recently got. It has cogs on it now and the guy I bought it from said it made 24 psi at 7200.....problem is the cogs leave me zero room for my radiator hose so i was going to switch to a serpentine setup. Problem is that I dont know what pulley sizes yield what boost levels.....trying to stay legal for renegade. Any help is appreciated and if anyone wants to work out a trade let me know.

I put a AFCO GM inlet/outlet style radiator in mine to clear the cogs. I have 77/28 cogs and it will make 25psi @ 7500 after the igloo. as far as serpentines, the YS renegade kit comes with 8"/3" but I am sure the renegade guys are using 2.85" pulleys and making 23-25psi.......

FYI Joker, I don't believe your heads are legal in REN.
