It would look great, but the turbos would over ride the somoramic effect of the manifold, not really worth the trouble. There is enought plumbing on a factory set up before adding any turbo. The control arm mount is near the front exhaust ports so not much hope of backwards manifolds fitting.

I think the trick with this set up would be synchronization. There is no common tract. The carb on the left could be seeing 5psi and the carb on the right could be seeing 15. Also, the left carb would be fed by the right turbo and vice/versa. Not things that can't be overcome, but something to think about. I think it would be a neat set up.

the power adder will negate the ram effect

An explanation as to why would be enlightning, and of course that statement also means, I guess, no turbo cars have/need any intake tuned ports also, because it would negate the power adder?

difference between pressure and vacuum

Well first, air fuel mixture inside an intake is never a complete vacum, it always has mass, it is also under most conditions moving, and the primary basis of the the long ram was using momentum of the above to extra pack the cylinder as the intake was closing. However there are a number of other variables, way over my head, regarding sonic pulses that also are the black magic of intake manifold design. They are both effected and tuned according to many variables, including cross section, surface roughness, geometry, wet or dry, fuel density, temperature, velocity, cam timing, compression, etc, etc. The main effected variable in turboing regarding ram manifold tuning would be a charge density increase, and maybe related varibale would be increase back pressure from the turbo, but I suspect that is more a cam timing variable. Therefore based on my simple explanation versus yours, I complelety disagree with your comment that a long ram intake "negates" the power adder.

I think he meant that the power adder negates the benefit of the long ram.

I simply can't resist the temptation to use the hot button word here "irregardless" , it is still an incorrect conclusion. The long ram benefit still exists.

I think 'negate' is a very poor word here. The more appropriate word IMO is 'override'. The turbos will override any ram effect with their greater ability to create increased pressure.
