Figure 13 below shows the result of these calculations, expressed as lengths (in cm) against RPM values. The initial observation is that in order to obtain the ramming effect discussed above, at a low RPM of about 2500, an intake runner length of over 5m would be required! This would be close to impossible to package in the FSAE car, as well as to justify the extreme increase in weight for the relatively little improvement in volumetric efficiency.
