Gentlemen:

I just put a new clutch and a set of rebuilt webers on my 67 S. The 40IDS3C's have the adjustable cam lever bar and were tuned on the dyno. The motor is quite fresh (I'm afraid that I can't be more specific - wish I could) the fuel pump is new and it appears, especially after all this work, to be running really strongly. It is also using an MSD box and coil.

What should I read as a power rating in either HP or kW at the rear wheels during a dyno test? What kind of losses are expected in the driveline? How can one work back to the flywheel rating? The factory's 160 HP (DIN) rating is flywheel power isn't it? What is a typical rear wheel power rating?

I was told that I am putting down 62HP to the pavement and that this translates to ~130HP at the flywheel. Further, I was told that the crappy fuel these day full of that MMT crapola could account for the 30HP difference between the factory rating and what was measured - is this true? Anyone else got some results to share?

Thanks fellas.
