What Would I Need
Bill, How do you come to this?
It's the new math... my mind gets fuzzy after midnite... Should have said 337 cid, Sorry
Logic, mainly. Ambient atmospheric pressure is generally referred to as 14.6 psi.
That is what a normally-aspirated engines has shoving air and gasoline into the cylinder when the intake valve opens,
Double it, to 29.2 psi and you now have
twice as much air and gas (ideally) entering each cylinder, virtually doubling the output.
A 225 would act like a 450 cid engine, if two atmospheres (14.6 psi, ambient, + 14.6psi. of boost) were going into the engine.
Cut the boost to 8 pounds (an atmosphere plus a half, virtually) and you have a 337 (225 X 1.5) motor. Those are ballpark figures, but the concept is backed up in a lot of forced inducton books.
Makes sense when you realize that basically, an engine is an air pump, and more air moving through it is going to affect its output on a quantative scale
.
Hope this helps,
