Hs{Lord Ernest Hives - Chair}1/LG17.2.26. OBJECT OF TEST. To increase power on 20 HP. TESTER. A.C.Lovesey. CONDITIONS. Test bench. SUMMARY OF TEST. These tests confirm previous tests on this engine to increase the output - that is, we cannot improve power to any degree by increasing the induction freeness. The question of increasing the power of the 20 HP. engine is being treated as urgent. The chassis weight on the 20 HP. is now 200 lbs. heavier than the original chassis. The chief additions in weight are :- G.111. Gearbox & Servo 37.3 lbs. heavier than G.11.
