I replaced the pulleys on the GN I just bought with RJC Racing stock size pulleys. I discovered that the crank pulley that was previously on the car was only 5.25" in diameter. The stock size pulley is 7" in diameter. My car's oil pressure has dropped from 7lbs to about 3 lbs after replacing the pulley with the larger stock size pulley. I'm just looking for thoughts and opinions as to what kind of affect the 5.25" crank pulley could have had on the motor. Should I put it back on and expect my oil pressure to raise? Could the overdriven crank have worn out any bearings? I'm dropping the oil pan right now to see what's going on. Thanks everyone!
