Increase power of Eagle engine. TESTER. T. A.{Mr Adams} Gibson. A.{Mr Adams} Rubbra. CONDITIONS. Test bench. SUMMARY OF TEST. It will be seen from the attached reports and curves that the Eagle engine is capable of being boosted up to a considerable increase in H.P. It would appear that we have by no means exhausted the possibility of improvements in induction pipes. Valve timing could also be usefully investigated further. Hs.{Lord Ernest Hives - Chair} | ||
