| -2- (d) Thermometers in positions as for previous oil test, including temperature of oil as flinging from bearings. (e) Readings to be taken at 4000 R.P.M. full throttle with varying inlet oil temperatures 70°C, 80°C, 90°C and 100°C. (f) Flows from sump and relief pipe to be checked by weight and of such a quantity that error of timing is not big percentage. That is sufficient flow say to take 30 secs. (5) Investigate 'bobbing' of oil level indicator. C.17. Following removal of B.17 fit this unit on bed and check heat to oil in similar manner and conditions as carried out on Wraith III. Power loss and back pressure with - (a) Std. 30.HP. exhaust silencer. (b) " Bentley " " (c) Chevrolet exhaust silencer. (d) Vauxhall " " ------- No.5.BED Ph.No.3.Unit In present condition of 'Continental' heads and LeC.5401 camshaft check power analysis of standard silencer. When completed fit the modified hot box and throttle body Rs. {Sir Henry Royce's Secretary} 462/3/4/5/6 now in stores and check power and induction depressions, also distribution and consumption (weakest maintained) B.9 Oil consumption tests to be continued. SINGLE CYLINDER UNIT. Repeat the power and detonation comparisons between the high power head with I/C. block, but with compression ratio raised to 6.4:1 against the standard Bentley unit which also has 6.4:1 C.R.
