In most US states the 911S was making 165 due to the air pump, whilst in California it was even detuned to 160 bhp. .

But: consider this. The '76 or "I series" k jet 2.7 l with 165 bhp not only comes with the galvanised shell, it is also producing more torque than the 911S. In Paul Frere's book, he describes it as follows:

"...it appears that the previous rating (of 175 bhp of the '74 and '75 model 911S- BR) was rather higher than average and only reached by the very best of the production engines. That the power out put is not less than before was fully confirmed by a Road Test published in the magazine Auto, Motor & Sport of October 25, 1975 in which the standing start kilometre time came down from 28.7 to 27.9 seconds and 1.5 seconds was chopped of the 0-100 km/h time. Only the maximum speed was slightly reduced from 225 km/h to 222,5 km/h."

Naturally, in this day and age most 2.7S engines had at least a top end rebuild and lost air pumps and what not, plus there might be a performance gain by about 10% by fitting SSI's . Indeed a 911S can be made to fly, but a 911 '76 might still be able to beat it, both in speed as well the ability to hold back the rust.

Vrijdag maar gelijk langsrijden bij Pelzer in Kerkrade, kijken wat ik daar wijzer wordt.
