Hey does anybody know if i will run into any problems with my supercharger, if i replace the stock pulley with a 2.5". If my car has 150,00 should i worry abou damaging the bearings in the supercharger, anybody please reply back thanks

when changing pulley sizes engine knock should be ur main concern.

A 2.5" should not hurt you. What year is your car? The 92-93 pulley is 2.55" not really worth the time to put a .05 smaller pulley on if you have a 92-93. if you have anything else then its worth it You should have some mods to back up a pulley though. the first is to have a 180* thermo

A cold air intake, 180* stat....and exhaust helps a lot too....Just a better muffler is more then plenty....a lot of us around here love the flowmaster and magnaflow mufflers......After those 3 things you're more than ready to do a pulley. When you do your pulley can I have your OEM???? I really need it!!!!

Yeah Imy baby is a 95 ssei, I have a cold air intake, 2.5' stainless steel exhuast with a flowmaster muffler. On the 95s the supercharger pulley is 3" and a little bit, so if i get a 2.5" do you think I will notice a difference?

yes you will notice a difference from the 3 to the 2.5. you will want to install the 180* thermo in addition to your current mods

coul you put your year and (95) and trim level (SSEi) in your signature so we can help you better

150,000 miles shouldnt hurt, ssei95 has mileage close to that and he is runnin the 2.5" pulley with no problems. your stock pulley size is actually 2.85" you should notice a nice gain, ill be puttin on a smaller pulley soon myself

Yup. I have about 135,xxx on her now and I did nptice a nice difference once I put on the 3.5. I'm sure my exhaust and intake have helped out a bit too.
