Sounds reasonable to me, but don't forget what configuration those tests
were done with. 108 mph on 90 bhp sure sounds like it must've had skinny
tires, skirts, no windshield and that metal tonneau cover; all to improve
aerodynamics and reduce drag coefficient. Road & Track only managed 106
mph, with a 100 bhp 57 TR3.
