Temperatures and loss of water. 4) Test with front bonnet shutters open, 60 M.P.H. 5) Test with front bonnet shutters open, 70 M.P.H. 6) Test with front and rear bonnet shutters open, 60 M.P.H. 7) Test with front and rear bonnet shutters open, 70 M.P.H. 8) Ignition retarded 8 notches, 70 M.P.H. Temperature test. 9) Standard test, temperatures. 60 M.P.H. 10) Fan belt slacked off with all bonnet shutters open, 60 M.P.H. 11) Fan right off with all bonnet shutters open, 60 M.P.H. Fan replaced. 12) Thermostat removed. Shutters held full open. Test for loss of water at 60 M.P.H. Checked up against No. 2 test. 13) Thermostat removed. Shutters held full open. Test for loss of water at 70 M.P.H. Checked up against No. 3 test. 14) Radiator shutters taken off. Temp. test at 60 M.P.H. Checked up against No. 9 test. 15) Test double supply from bottom tank to water pump. Checked up against No. 9 & 14 tests. 16) Commercial spirit. 60 M.P.H. temperature test. against No 9 17) Commercial spirit. Mixture 5 notches strong. 60 M.P.H. ditto temperature test. 18) Ignition retarded 8 notches. Conditions same as number 17. ditto No different result. This test had to be cut short owing to track being closed. | ||
