1967 Pontiac GTO - Supercharged Silver Streak
|
With a .030 over 428, a mild cam and Edelbrock heads, this ProCharged Pontiac puts 5-6 lbs. of boost to good use, posting high 10.90 quarter-mile times. On the dyno and naturally-aspirated, the engine produced 450 lbs.-ft. of torque at 4900 rpm and 465 hp at 5700. With the engine supercharged and intercooled and on SDCE's custom land and sea engine dyno, it produced 582 hp at 5900 rpm with 6.3 psi of boost, and 490 lbs.-ft. of torque at 3000 rpm that peaks at 527 lbs.-ft. at 5400. Scott related that the engine was dynoed with everything on it including the water pump and alternator, instead of stripped. This way the power numbers are more realistic and somewhat closer to chassis dyno figures. He says that he usually sees about a 28-horse difference between dyno testing a stripped engine and a dressed engine. View Related Article
