i have a 1996 firebird formula
it's currently my daily driver and ive added about ever bolt on there is.
is it worth it to pulley it?
i've looked at a bunch of 20% and 25% pulley kits

i also have a 12 inch low profile Rockford punch sub
and want to keep my air conditiong

is it worth putting pulleys on it?
does anybody have a pulley'd firebird?
how much will it actually effect the accessorys in the car?

what are your guys opinions?
thanks

 

Doesn't save much HP at all, and if you go too far on the underdrive ratio, you're going to see the volt meter dip into the red at stop lights, in hot weather, headlights on, AC on, subs pounding. If you have an A4, its worse because of the lower idle speed (550rpm in gear, as opposed to the M6 800rpm).

You decide if its worth it, looking at this:

I think I've suggested this before - why not use the "signature" field to provide useful info about your car, rather than the bolixed photo links?????

 

An underdrive pulley is one of the worst things you could do to a street car. They don't even do anything anyways. Best thing I ever did was remove mine.
