1981 Porsche 911 SC Dyno run - 143.3 bhp

Sorry 83flatsix but milo is right here. The hp rating is not the average, not for porsches. Porsche would throw out any motor not meeting the hp levels so it is actually a minimum. You'd be surprised how much of that power lasts over the years on these cars. Video says 143.3 bhp

bhp=brake horsepower

brake horsepower= horsepower before any losses from drivetrain, tires, etc.

therefore the Porsche factory and these guys are testing the same thing.

But you've got an 83 sc, and thats awesome

Um, you obviously don't understand manufacturer specs. The stock HP rating is an average based at the actual engine's crank in it's best condition-NEW. The dyno is real world and accounts for drivetrain (transmission) loss ( about 14% for 915 trans) and engine wear. Plus a dyno is only as accurate as the end user's data input!
