Underdrive Crank Pulley

[maximus]

Does anyone know if they make an underdrive crank pulley for the 4g64?I heard that you can use the 4g63t underdrive pulley but the part#s do not match.If anyone knows if there is one out there or where it could be found let me know thanks maximus.

OBX makes one. Look here: https://www.thegalantcenter.org/viewt...ve+crank+pulley ('https://www.thegalantcenter.org/viewtopic.php?t=10287&highlight=underdrive+crank+pulley')

My question is... Is it recommended to run an under drive pulley without the dampner on a daily driver?

That one will fit the spyder but will not fit the 8g i4.I found one and have it ordered but not 100% sure it will fit.I will keep everyone posted on this.It is upto you if you want to run one on your car.I am going to and I am sure there others on here that will if we can find one.My friend ran one on his eclipse and no side effects from doing so.If you are undecided then wait and see what happens to other members and make your decision from there.It may throw a ses light but nobody knows yet.Thanks maximus

just an fyi, if you do some research on the evo or dsm pages, nobody runs an underdrive pulley on anything but full blown race cars. like cars that come off a trailer. without the vibration dampener it messes up the balance of the bottom end very bad
