i got an 05 ss/sc that is pretty much stock all it has is a injen intake. i was thinking about adding a smaller pulley and belt, will this give me anymore horsepower, if so what pulley do i use and what belt. i know there is tons of things u can do to these cars but money is pretty tight right now.

 

if you drop a pulley you need a tune so buy a stage kit from zzp or ottp it will be cheaper in the long run rather then buying everything seperate

 

here are your choices

- Over The Top Performance

Cobalt & Ion ---> ZZ Performance

 

Ok i'll check that out thanks.
