I NEED MORE BOOST!!!

hey ya'll ive been tryin to research this but im not getting too much info. im runnin the v-1 vortech blower on my 02 gt. its pushin just shy of 10psi and im lookin to up it. im tryin to get around 15-18 psi and wasnt sure what pulley to run. i really dont wanna change the blower pulley as it will void the warranty, and ideas as to what crank pulley will give me about 5-8 more psi??? thanks any input in awesome :flag:
 
What are your current mods? What tune are you running and what are you putting down now? Are you running an intercooler? You need to answer these questions before people can help you. If your motor is stock? Leave it lol.
 
15-18 pounds will almost certainly break the engine if you still have the stock rods and pistons.

You'd also most likely need fairly extensive upgrades to the fuel system to support the sort of air flow associated with 18 pounds of the boost.

Like slayer sez, you need to tell us what mods the car has now in order to offer intelligent suggestions as to how to meet your goal.
 
It will give 15 lbs but like said above if you are running a S trim it will be running out of breath. You would most likely see more gains from forging your rotation assembly and getting new heads/cams.... then thinking about turning up the pressure. :nice:
