Think of your intake manifold like a straw. Sucking in with nothing blocking the end prdouces no stress, block the end with your finger (or a throttle vlave) causes it to collapse. |
Ok I see where my confusion was there, I was taking that thought from the manifold pressure sucks article and just applying it where ever the hell I saw fit.
Can anyone explain the limiting factor in the sea level and altitude pressure chart for continuous operation that I linked earlier. What are they concerned with keeping safe as MP/RPM spread increases and how does this link with different engine powers having different MP/RPM spread limits?
Thanks.
