are they really worth it on the dohc motor?im lookin at the ebay ones there goin for like 40 bucks. it helped on my tsi a little? idk

 

those arent underdrive pulleys. only "lightweight"
do they make a difference? i doubt it.
they look kinda cool i guess, if thats your deal.

 

i dont care about the kewl polished aluminum pully i just want one thats smaller and lighter.which the pullys on ebay are just lighter.if it was up to me it would just paint the pully black anyways.

 

they arent smaller.
only lighter.

save weight somewhere else. you wont notice the difference

 

depends on how much lighter they are, when i put light weight pullies on my Z i noticed it, and the dyno notices them too, usually 5 to 10 whp.

 

It depends on what you are doing with your car.

Lightning your drivetrain will gain lots of power. If you have a lightweight flywheel and driveshaft, I would probably get a lightweight pully aswell....as long as it is good quality. Every little bit counts.

 

Exactly. Weight reduction if any is always worth it.

 

I have an ASP pulley and its definitely smaller. You even need to buy all new belts because the old ones are to big.

 

KAs dont have the greatest harmonics. don't do it. I've been in several KAs with them. Not a thing noticed. I still pulled on them from a roll with my stocker. And doing timing is kind of sucks because the timing mark is soo much further away.
