As I have mentioned before (to great scorn) the old road tests for RN cars claimed performance generally better than obtained with the RP and early Rubies. 50 mph with ease was claimed yet later cars strugged to reach this at all. RN owners also claim notable performance. It is possible the origianl road tested cars were discreetly non standard. The commonly quoted bhps may not have been maximum. To confuse the issue the cr was raised late 1933 part way through the RP. With reduced breathing the high rpm bhp may not have been improved.
It seems problem arise with gravity feed and high mounted carbs.
