totally agree with the theory, the assisted gas extraction by joining them as opposites, rather than linking down each side, works for me, no argument there.
i can't conclude the same for the crossover pipe that links the cylinders diagonally, this will provide the same gas extraction as the stock sided system, just with added complication of pipework.
So, the "Ansa" styled crossover, front cylinders linked, rear cylinders linked, seems to be the "performers" choice.
However, having had a great discussion with AL33NUT, we may do one of the two things for his project personally, and another for those who want something quite different.
I believe we can improve on the stock layout, by applying modern materials and assembly methods, if we can maximise the flow within the room allowed, i reckon we can build an improved performance manifold with the original design in mind, for those who want a lifetime and improved manifiold, and with close to stock sound too.
Or, depending on which way we swing once he has his car ready, we may do the Ansa styled crossover staright away and go for out and out free flow and extraction gains, but i doubt this will sound quite the same, so some purists may not want this method.
I think both will be great, and more a personal choice than anything.
ps - thanks again for the call Nnamdi, good to speak to you, good luck with your project, and we'll hook up again soon.
