Well, Mark, you may well be right. I'm just going from distant memory. (I don't have "The Porsche 911 Red Book" to hand right now.)

May be that Californian-type(?) states were more oppressive with their restrictions, and that's where the 265bhp figure relates(?)... It's just that the figure stuck in my mind because it's exactly the same as the 1977 3.0 RoW 930! (So bigger U.S. engine, intercooler, etc. only gets to where the Euro 3.0 to start with.)

Then we have to take into account the fact that Porsche Dynos every engine that comes off the production line, and the quoted figure is actually a minimum (when most manufacturers quote an average). I also know that in 1984, the peak torque was upped from 305 to 315FtLbs in Euro cars.

But anyhow.. Glad we're all agreed that the figure is probably somewhere between 315 and 330bhp at the Crank.
