I have a motor with aftermarket hci and its idling at around 600 rpm, it sounds bad ass but is this dangerous for the motor, does it turn fast enough to lubricate the whole engine properly?
i would through an oil pressure gauge on it to be sure. dont rely on the one on the dash that dosent give you actual pressure. i have my idel set at about 900 because i found any lower and my oil pressure dropped off significantly. hope this helps
