We are today putting B.56.BN.{W.O. Bentley / Mr Barrington} into the Shop to be prepared for radiator tests which we are to carry out at Brooklands. Will you please carry outthe following on this car - 1. Fit the 58.MM. Mk.Vl.{V. Lewis / Mr Valentine} matrix radiator which has been prepared for these tests to this car. 2. Rig up a hand control for the radiator shutters (operated by means of Bowden cable) from the inside of the car - we will hand you the necessary cable and casing for this purpose. The thermostat will of course be disconnected. 3. Fit the thermostat casing outlet (which we will hand you) to the cylinder head and couple up the by-pass from this to the two hot spots as has been done on the test bed engine on No.2. bed. This will entail raising the air silencer or omitting same altogether. 4. Fit a top water outlet pipe with a thermometer pocket for a Negretti & Zambra thermometer - also a bottom water pipe with a similar thermometer pocket ( we can supply the latter in about two days time. 5. Fit the Negretti & Zambra thermometer (which we will supply) to read (a) Top water outlet temp. (b) Bottom water inlet temp. (c) Air temp. behind matrix. (d) Air temp. in front of car. 6. Ensure that the three fans(which you have prepared for these tests) can be fitted to the car without any difficulty. 7. Fit the steel bonnet which has been prepared for this car (it is at present in the Exp. Garage) Rm{William Robotham - Chief Engineer}/Std. | ||
