Would you also change the IVO and IVC points to take addvantage of the increased speed?
Yes & no, .. that's likely a question for Lloyd the cam guy in my shop, ..
we do cams by committee in my shop, ..
if you have the airflow CD's from Don, go back and listen
to what Mike Chapman refers to as "down force", ..
the energy of the charge entering the chamber, .. ..
I think there's a 100 ways we could "play" this, .. but air speed
has always proven to make power, .. and air speed has energy
in inertia , . .
Well if you reduce the throat area to increase air speed through the throat,
a by product of the smaller throat will be better mid lift flow numbers
and in some cases reduced high lift numbers?
I'm not saying this is right or good, .. just throwing it into the conversation.
