With the above theory on the electric you should be able to massivly
boost low end torque by getting the low rpm boost closer to the detonation
limit.  In some types of vehicles this would be desirable.  I have noticed
that a vortech engine with x hp is not as fast as similar built up engine
with the same x hp.  Mainly because the vortech has a good high rpm curve
but the built up has alot better low/mid end torque.  The vortech peak
close to redline, and the builtup peak quite a bit lower, allowing
more useable hp.
