That isnt possible.
The problem is that we have a fixed set of lengths in the pipe that can only develop a depression over a certain period in time, but the rpm is varying
as we accelerate thru the powerband.
Thus as I said above the point of max depression moves in relation to BDC as the rpm varies.
We can bias the efficiency of the diffuser to act at the front side of the curve, by having the max ( widest area below atmospheric ) depression occur later
within the pipe length, or we can design it to create then max power around peak, or we can design the pipe to operate better in the overev.
The max depression part of the equation is confined quite rigidly within the boundary's set by a 32% header and a 68% mid section, but the superposition
resonance effect is governed by the port timing and the pipe tuned length, so is much more able to be "tuned" to a specific end effect.
Here is the same engine trace showing the before peak curve - notice no superposition at EPO, and early peak depression.
Then peak Hp - we have superposition and max depression around BDC.
Then in the overev - we have big superposition and late max depression.
This scenario generates the greatest peak power, and gives a long smooth roll off , of the power into the overev.
It possible to reverse the superposition position, but we will always be fighting the impossibility of stopping the natural movement of the peak depression event
due to the fixed pipe length.
We can change the depression curve shape with clever diffuser design, but it will always move from early to late in the cycle as the rpm changes upward.
Ive got a thing thats unique and new.To prove it I'll have the last laugh on you.Cause instead of one head I got two.And you know two heads are better than one.
