My 1929 RK performs well on its 22FZ. I abandoned the FZB because of Mazak rot. Fuel consumption is about 35mpg driven enthusiastically. It will certainly reach 50mph with no problem and I've had it off the clock (60+) on downhill stretches. Speedo agrees with my sat nav. It has the post 1933 cylinder head which I suspect has been skimmed.
Under the bonnet all looks original which is a bonus.
In the mid 60s I had a 1930 RK fitted with an SU which certainly had better performance. Would reach 60 quite readily and cruise at 50 happily. The windscreen peak was missing which I'm told contributes to drag. It also had the HC head. Fuel consumption was about 40 mpg.
In the 70s I had a 1934 4-seat tourer with standard set up, 26VA & LC head. It performed much the same as my current car but fuel consumption was markedly better. A journey in 1967 was following a friend who was towing a trailer with my 1937 Ruby on it from Dundee to Cambridge via Liverpool. Filled up before We left, filled up at the end. 10 Gallons total and a bit over 500 miles, so better than 50mpg. But it was a slow journey, seldom over 40mph, steady cruising on an open road.
