Am thinking of using this cross ram manifold with injectors added in a row to the top of the valley between runners and then something like 100 mm Long X 50mm Diam ram tubes into two plenums strong enough to withstand full engine vacuum, fed by 2 X 75+mm throttle bodies sucking cold air from somewhere suitable.
I would use individual throttle bodies if I could get some around 48 - 50 mm Diameter second hand for a good price, but that might be real hard to do here in SA (need 8) and anyway linkage gets real complicated. I don't think I will lose much power anyway and will not notice any torque or response differences between the two systems.
A check on two engine modelling programs shows an approximately 20% power gain over a two plane manifold with Holley Carb, plus I believe I might get some significant fuel savings at normal cruising speeds (Under 2000 RPM), That should see me well over 500 BHP
Any thoughts or guidance would be welcome.
