that what air intake i have its nice and big

 

You can probably get away with an upper/lower but it will create a lot of heat. Get a Killer chiller with a bigger intercooler reservoir and can pull off an upper/lower while still making good power. Also port the blower and get a SBTB and plenum and port them to match the blower inlet. All these will help blower efficiency.

 

if i got it down to 17 psi will i be safe then

 

i got a 8 1/2 inch crank pulley with a 2.76 inch upper pully making 19 psi can i change the lower pulley to 8 inch? how much would it bring the boost down? how much boost you running and how much horse with your psi? thanks
