Ok what are the pro's and con's of doing theses 2 mods which are the mods that I want to do . By pro's I mean hp gains etc. and by con's I mean , blowing up engine , trans etc.

1. Porting and polishing your blower.

2. Smaller puley swap (3.25" to be exact) also with the puleey swap I am still getting mixed reactions ...What will I NEED to get besides the pulley to make sure the engine is fine after putting a smaller pulley on it.

 

when i took my blower to machine shop to get pulley setup put on i asked them about porting blower and they said it wont do much for our cars and i have 3.25 pulley swap now and cooler spark plugs and ive had no problems whatsoever so as long as u dont go ne smaller u will b fine

 

well first off, does anyone have pics of the underside of the blower?

second, does anyone know the size of the inlet of the blower?

This is really going to affect whether it would help or not. IF there is a step from the TB to the SC, then yes it will help a little just straightening out that air flow. And if the oulet is not a perfect triangle, then that will also help. Although it usually help a lot till you start dropping to smaller pulleys.

 

Carbomb.... Performance specs with the 3.25 ? Did you pay someone to put it on? Did you need a smaller belt? If yes to any how much roughly.

 

Carbomb - I'm with him any gains ?
