I'm not a fan of undampened crank pulleys. They're there for a reason and that's to dampen the engine harmonics. Which helps the engine last longer. Imo just get a OEM type pulley.

If you want to change the crank pulley look at a lightened crank pulley rather than an under drive set. There is no rubber to give out and your engine will spin up easier.

isnt it just the same thing under drive and lightened crank pulley. i just cant come up with 100 versus 40 or 60 i can. im sure the rubber is there for a reason but since ive owned the car the pulley is getting worse and worse my belt squeals like crazy i mean shit the motor has 240000 so i wouldnt be suprised if i had to replace the motor soon

underdrive pulley changes the speed of the accessories, a lightweight is the same diameter but lighter. an underdrive pulley could theoretically end up heavier than stock.

this right here.

Plus do you really want an unknown quality pulley on the front of your motor? If you opt for a lightweigh pully check to make sure its not to light as that can cause issues as well, I belive it was a misfire issue, at least for my '10 impreza. I put the grimmspeed one on my car with no issues in 25K miles now.
