lower psi

[05silvhemimag]

i have the 25% underdrive pullie and wondering when i stick a blower on thier i would run a lower psi wouldnt i because the accessories are runing slower. so i would need my stock pullie back on or a diff size on the blower??

Just use a smaller pulley on the blower. How much boost do you plan on running?
