What doesn't make sense in this argument, to me at least, is how you can get
more HP from air alone and not air and fuel.
If there was not the accompanying fuel to accommodate the additional better
breathing from the big valve engine, - the van would be running lean, right?
So, if Boston Bob's van moves more air, it does seem to me that the AFM
would report this, and the ecu would increase the pulse length of the
injectors, to supply more fuel.
