For every piston going down there is another going up... Constant volume in

Hi Dave
So what you're saying is there is no pressure in the crankcase? Constant
volume sure, you don't change that but how about pressure resistance from blow
by?
So are you saying you don't make any more power with a dry sump oiling
system and the resulting crankcase vacuum? If you admit dry sumps make HP, how
do
they do it?
If that is the case, why do drag race engines run crankcase vacuum pumps if
they don't have a dry sump?
