Pulley Selection V2 SI
hi all.....
just about done changing out the Powerdyne bd11a on my 360 Chrysler for a V2 SI that i have just purchased. The powerdyne was not going to give me the boost i want.
Anyways what i would like to know is what head unit pulley to use for say 12psi boost @ say 6000rpm, 7" crank pulley, 3.5 rear, auto. i have a couple of spare pulleys from the powerdyne, but they are 2.7 and 2.9. think they may be too small.
