about how long does it take to put underdrivepulleys on your car??

 

Like an hour or so...maybe less, depending on a few things.

Not too difficult...

typically takes longer to actually remove the belts than it does to install the pulley.

i noticed a small gain on my old Iroc...and only had problems charging when i had my manual fan switch turned on, but it wasn't bad

 

Took me about an hour as well. Only thing I dont like about them is the water pump slowed down so when in traffic it heats up a bit more.

 

Take notice of the side effects of the underdrive pulleys.
