| GRAHAM PAIGE. We tried the largest of the 6 Cylinder Graham Paiges fitted with a Weymann Saloon body weighing 4124 lbs. complete with one spare wheel, petrol, oil, and water. The car is taxed £30, being a treasury rating of 29.4 H.P. The wheelbase is 121" and the car is therefore comparable in size with our 25 HP. though slightly smaller. The model we tested had done about 6,000 miles. COOLING. - We carried out the standard 60 M.P.H. test. As will be seen, the car is not so well cooled as the Phantom ll even when the Phantom ll is run with its bonnet shutters closed. When run under similar conditions of bonnet ventilation the Phantom ll is no less than 7° C. cooler than the Graham Paige. As will be seen from the particulars, a "Fin & Tube" type of matrix is used which we know is not very efficient; and the matrix employed is of the modest dimensions. Also the means of getting the air away from under the bonnet, while quite good, is not exceptionally so as on the MAXTON. Therefore the car really runs cooler than one might have anticipated and we can only suggest that this may be due to its high top gear ratio. We also know that combustion chamber design can have a considerable effect on the amount of heat to the cooling water and judging by its performance the combustion chamber design must be particularly efficient on this engine. PERFORMANCE. - The speedometer we found to be accurate. The general performance of this car is very good indeed. | ||
