We attach herewith power curves of the unit we have just fitted to 27-EX. the "Model" car. The compression ratio is slightly lower than 5:1 but should only make a difference of 1% to the power, output. The air silencer mentioned is the experimental one of which you already have particulars. The car has completed tests on the track and has shown an excellent turn of speed. A full report will follow in due course. Ha/Rm.{William Robotham - Chief Engineer} Attached Print Rm.{William Robotham - Chief Engineer}D.26. | ||
