No. 49230 44580 REF. Hs{Lord Ernest Hives - Chair}1/LG5.4.24. TESTER. A.C.Lovsey. Y3H OBJECT OF TEST. To obtain data of exhaust system to be used on EAC 111. CONDITIONS. Standard 40/50 engine on test bench - R.A.F. Indicator. SUMMARY OF TEST. These tests and road tests prove that the modified exhaust system will not cause any appreciable drop in H.P. Further tests are in hand to prove whether exhaust noise has been increased or whether induction roar is manifest. Hs.{Lord Ernest Hives - Chair} | ||
