Have the 3.60 pulley on my car right now, just rebuilt the tranny with a shift kit, i want some extra boost out of the supercharger, but still need the car to stay reliable, i was wondering what the smallest size pulley i could safely go and about how much of a gain it would give me? thx

 

also, meaning can i buy JUST a smaller pulley without having to get bigger injectors, etc. and if so how much smaller

 

Probably down to a 3.12" pulley with just an intank Walbro fuel pump. I'm having no problems... get ASP tensioner/idler pullies too, to replace the plastic ones.

 

who sells those pulleys?

<total newb to boosted world

 

what kind of power and 1/4 times are you running with the 3.12?...estimates on how much all the pullies and the fuel pump would cost?

youre looking for the 6-rib

 

Don't know... i pulled 247 with the stock 3.6" but haven't dynoed with the new pulley and ported TB. Walbro GSS342 runs about $100.

 

I have a 3.33 pulley and the 6:1 fmu if you are interested.
