A Porsche motor ?

[roverman]

Not saying you should-but, over on Speedtalk, a skilled  fellow twin turboed  a 928S  motor.  93 octane, completely stock engine/drivetrain, except spark/fuel management. Results, 711hp at wheels and 662 torque. All aluminum motor weighs approx 490 lbs.= lots of aluminum ! Long live the mighty B cam(s) !  roverman.
