Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}/LG14.5.25. to contend, is the methods of testing usually employed by those who complain of overheating. We have dozens of reports taken in various places which are absolutely value-less because the results are not reduced to an absolute basis, nor are accurate instruments used. We admit that radiator tests are exceedingly difficult to carry out satisfactorily, this is part of the overheating problem. We ourselves have only recently evolved road tests by means of which we can definitely compare the value of alterations which we made to a car. We cannot reproduce the effect of altitude or atmosphere likely to be encountered on the Continent, nor can we accurately predict the effect of the increased H.P. of the EAC. as regards overheating. This latter factor may prevent customers using full throttle on the majority of the long hills that they frequent, such as La{L. A. Archer} Turbie, which will inevitably confer considerable additional benefit upon the EAC. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
