Under drive Q:

[MitsubieMike]

New to this forum, does a lighter underdrive pulley really do anything for the car? Iv heard different thing, any othr suggestions for things to put on a gsx, iv got tons of stuff in the garage sitting ?

I don't even understand half of the things you just said. As far as the underdrive pulley goes, of course it does something for the car. The question is whether it is worth it to you. My opinion is that the money for that pulley could be better spent on something that will be more beneficial to your car in terms of hp. Your best bet is to follow the upgrade paths here on this site. Also, remember to use the search button as it will be your best friend on this forum.

Note: I would be careful with your grammar...the mods will get on you eventually about that.

Thing about switching out the stock pulley to the underdrive pulley is that the stock pulley is also the harmonic balancer for the crankshaft (if you notice that the stock pulley is actually a two piece pulley with a round of rubber inbetween the two layers..) an the harmonic balancer part of the pulley counteracts the vibrations coming from the crank to help the crank run smooth.

If you go to a solid underdrive pulley, the vibrations coming from the crank, being not counterbalanced out during the power runs, will eventually destroy the crank.

Something to think about. - DSM

i agree with imagine. i would look into improving your intake or exhaust before buying a under drive pulley. also check out the freebie mods in the tech section since you have a gsx
