i have a 1997 buick regal gs i was wondering if anyone could tell mehow to boost the psi on the supercharger? ........much help needed

 

before you raise the boost you want to make sure your engine is running to its full potential now. if you are unsure of the last tune up, i would suggest new plugs, and wires at the minimum.


after that, you need to scan the pcm and make SURE you have 0 KR (knock retard).


when that is all good, i would suggest a fwi, or a cai of somesort.


then think about raising the boost. you can achieve this by simply putting on a smaller pulley. you can get a press on pulley for about $60. but you may look into the modular pulley systems. more commonly refered to as MPS. those you can easily swap out pulleys with just a few bolts.


for the first pulley drop i would suggest a 3.5 inch. and after that you need to scan again and make sure you still have 0 kr.
