From the email list

The real surprise was that at about the 4000rpm point, all the cars had exactly the same power figure! After that, the cam profiles of the two GT cars (mine and Joe's) separated us from the auto's.

Although all the cars pulled pretty good power curves, I thought they were all slightly down compared to what I have seen on previous occasions at the same venue. Mine, for example has pulled 338 estimated bhp before, but only hit 331 today. Several factors contribute to the varying figures from day to day, but the real benefit of today was the comparison of all the cars together.

Considering the varying attention these engines get, and the fact that they are all well over 20 years old, it's a real testament to the German engineering that went into the design and build of these fantastic power plants ;-)

2009 trip to Surrey Rolling Road

On a (rare) beautiful December morning, six 928 owners headed for Surrey Rolling Road in Chobham. As it turned out, we had a fantastic mix of pretty much every engine configuration that Porsche made for the 928. This was going to be a rare opportunity to compare the power and torque of the different engine versions fitted to 928's.
