as I posted a few min ago, my main partially destroied itself this morning, so I am replacing belts.... I am now thinking that this would be a good time to do a underdrive pully install, but I am not sure which ones to get. I have read a great deal about them on the forum, (and yes, I searched) but I am still unsure. I have heard that some are difficult to install, and you can hork up your car if you mess up, while others are much simpler to install. is this true? do you see equal performance increases with the different brands??

 

the hardest main pulley to install is the unorthodox one but it yields the greatest gain. the easiest one to install is the SRmotorsports one which doesnt require removal of the main pulley bolt and a chance of droppin the needle bearing
i myself have the unorthodox pulley and the hardest thing i found about it was gettin the main pulley bolt off. it took a little over 200lbs on an air compressor to loosen it

 

I run the SRMotorsports pulleys (Indigo)...no compressor and air pump...no issues

 

another dumb question:

how many pullys do I need to replace?

 

well it all depends on which ones you want. the aftermarket pulleys that are available are for the main crank, alternator, water pump and power steering. i have the full unorthodox set installed on my car. if you want then i can take a pic for you

oh, and just so u know u will need a new belt no matter which pulley(s) u get
