Huckerby}2.9.38. Will you please design a scheme to adapt a Kestrel type of Supercharger to our portable rig engine which is a Wraith II unit. This will be used for experiments on the effect of air speeds in the air intake and boosting of engines. It should be arranged so that the delivery from the blower is accessible for adapting to engines. Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell} | ||
