The main feature of the engine was its extraordinary flexibility. We were told that it developed 90 HP. at 3500 r.p.m. CLUTCH. Light, and free from shudders. BRAKES: Too much pedal pressure required. Direct operation, no servo. The excessive pedal pressure was explained by the fact that the brakes were arranged to require the minimum adjustment through the 24 hrs. race and consequently the least possible pedal travel had to be employed for their application. These brakes were not very effective giving one the impression that there was not very much on the front. Even so, the steering pulled to the left on violent application. STEERING. The steering was light, not as high geared as some racing cars. It gave a very good lock, was practically irreversible, there being little or no self-centering, and minimum road shocks. There was far too much steering column movement. The steering column requires support. The steering produced a surprising feeling (for a racing car) for wandering and lack of selectiveness at high speeds (See suspension). SUSPENSION. The suspension on this car is absolutely execrable for touring purposes it being impossible to ride in the rear even with the shock dampers slacked off with any suspicion of comfort. With the dampers slacked off, the back axle danced contd:- | ||
