OBJECT OF TEST. TESTER. Tests with Mercedes Supercharger. W.A. Robotham. CONDITIONS. Tests bench conditions. SUMMARY OF TEST. The Mercedes engine has given generally poor results on the test bench. We have had two inlet valves break and fall into the cylinder - fortunately not much damage was done. The distribution was very poor. The carburetter is erratic. We find that we could, without much difficulty fix the supercharger to a 20 HP. engine on the test bench. Hs. {Lord Ernest Hives - Chair} [Watermark] DICKINSON BOND | ||
