| V634 To DA.{Bernard Day - Chassis Design} From Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Hs{Lord Ernest Hives - Chair}/RmL/LG24.1.28. TORQUE REACTION. +8005 We have been running the sports car with the rubber mounting at the rear and solid mounting in front. The result was not the same as that which we obtained with our original experimental rubber mounting in the rear and 2 point solid mounting in front as we find that with our present arrangement torque reaction is decidedly worse. In any case, at present we have very much more torque & re-action to deal with than we had when we carried out our last test due to the unit that we are using being 5/1 comp: ratio and new induction pipe giving better low speed torque and the standard camshaft which also gives better low speed torque than the long duration. At the moment torque reaction is our most severe problem on the sparts car and we have put it No.1 on our experimental tests. We therefore think it would be advisable for you to await some of our results before completing the designs for EAC.10. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
