Are these difficult to install? Anything special I will need for install? Will this mess up idle or a/c at all? How much power should I expect from something like this and will it be noticeable?
Ah ok, so how much of a power increase am I looking at? In your opinion are these worth it with no other engine modifications at the moment?The piggy back you are adding a pulley to your existing crank pulley because they dont have a torsion dampner. The steeda pulley completely replaces the crank pulley.
