Ram Intake Manifold
Produces up to 100 lbs/ft more torque from 1000-3500 rpm
Negative Supercharging ram intake manifold is a compact 18" long runner dual plane 4BBL manifold that produces up to 100 lbs/ft more torque from 1000-3500 rpm and improves fuel economy. The ram manifold uses megaphone shaped runners and long tubular plenum chambers with a special size to force a lot more air into the engine over a wider rpm range than conventional intake manifolds.
The picture of the ram intake manifold is for fuel injected engines. Carbureted engines will use the same intake manifold design as the EFI manifold but with the 4BBL carburetor in the upright central position as conventional 4BBL intake manifolds.
