Oldsmobile 455ci - Fortified 455
|
Steve Brule bolted the motor onto the dyno and installed a Demon 850-cfm carburetor, MSD-6AL ignition, and a set of Hooker headers for the dyno test. Three pulls were made on Westech's dyno, showing the near-stock 455 was making 403 hp at 4,500 rpm and 533 lb-ft of torque at 3,600 rpm. The most important aspect of the test was shown by the oil pressure. Throughout the dyno runs, with an oil pan full of 20W-50 Mobil 1 synthetic, we noted that the engine produced a steady 75 psi oil pressure and peaked at 90 psi. Prior to installing the oil restrictors, this 455 produced 50 psi at idle and 60 psi under hard acceleration. Under extended periods of hard acceleration, this would fall off considerably when the oil temperature rose. Typically, pressure would fall to barely 15 psi at idle. With the oil restrictors installed, the motor produced a minimum of 55 psi, even when the oil temp approached 240 degrees. View Related Article
