reversion and intake manifolds
 
is there any correlation w/ the type of intake manifold used and reversion???

Re: reversion and intake manifolds
 
intake reversion, exhaust gas reversion, or exhaust water reversion ?

No.

Ditto, no.

I agree with No.. Unless you are going to run a supercharger.

Re: reversion and intake manifolds
 
Actually, a positive displacement supercharger can help fend of exhaust reversion. The spinning rotors seem to help stop/dampen pressure going from comb chamber to intake port.

Centrifugal blowers don't seem to have this benefit since the tb/carb throttle blades are afterwards and it does not have rotors sitting/spinning atop the the intake ports like the positive displacements.

=====================
When both valves are open the intake port, comb chamber, and exhaust are all open to each other.

So, I say Hell Yes, the intake can influence this.

=======================

I may be off in my thinking + knowledge, so let's hear more opinions.

That interesting, but he asked if the intake manifold can cause reversion, and the answer is still no.

There is definitley reversion in your intake manifold, especially in marine engines where the motor is under constant load and carb openings tend to be larger. That is why large plenum intakes are more desireable to dampen the paulses and create more top end power.

He asked IF the intake manifold caused reversion, not if there was reversion in the intake manifold.

To clear things up, heres the definition of correlation. Making my response relative. I think one of us has misunderstood the meaning of correlation.

n 1: a reciprocal relation between two or more things
