University of Oklahoma. (Redirected from Oklahoma University) The University of Oklahoma (OU) is a coeducational public research university located in Norman, Oklahoma. Founded in 1890, it had existed in Oklahoma Territory near Indian Territory for 17 years before the two became the state of Oklahoma.
Normal idle on MOST cars is 850 RPM at normal operating temperature. If it is idling that high, you may have binding linkage or the choke is not fully opening. If it is BANGING into gear, you could cause other drive train problems. You may also have a RUN ON condition when you turn the key off.
For example, if we divide a ring gear with 41 teeth by a pinion gear with 10 teeth we find that the gear ratio is 4.10:1 (41/10 = 4.10). Tire diameter will also have an effect on a vehicle's final drive ratio. As tire diameter changes, so will engine rpm at a given speed. We can demonstrate this with the simplified formula: rpm = (mph x final gear ratio x 336*) / tire diameter (*see Formulas for Success sidebar).
