Power outputs

[David Stepney]

Interesting to note that the early RP handbook for the crash gearbox cars (Publication 972B) quotes the HP as 10.5 at 2400, while the later handbook for the 2 synchro cars (Publication 1095) quotes the HP as 12 at 2600.There appears to be no discernible difference between the engines, unless, as Ian Williams says, there is some subtle difference in the cylinder heads. My car will also do just about 50 mph on the flat (it was actually recorded at 51.6 mph along the A494 past Bala Lake) so I suspect my engine produces more that the claimed 10.5 horse power too.
