Guys my dad is currently in in Detroit and his first cousin is a machinest.

My dads cousin said he can machine down my pulley to any diameter I want.

I have the Code 3 pulley which is 65mm I think? now I'm thinking of giving him my original pulley to machine down to 60mm BUT I'd only use it for drag racing I know it can overrev and fry the supercharger.

My question is how much extra boost and how much quicker will it make me in the q/mile? is it possible to make it even smaller then 60mm? with added bonuses?
