Magnus V3 Cast Aluminum Intake Manifold: 1G DSM / VR4
(0 reviews)  

Using the EVO V5 intake manifold as a starting point, we used advanced airflow design technology to match the intake manifold to the 1G DSM head. The 1G cylinder head has unusually large intake ports, originally designed to support a variable runner length inlet manifold design used for a short time in the early 1990s. Conventional wisdom holds that these ports are too big, yet numerous tests and comparisons through our research have proved quite the opposite if you are trying to make big power. The large ports are well suited to the flow requirements of the increased mass and density of the air charge needed to achieve in excess of 1000 horsepower. High horsepower cars require a large volume of fuel (especially in alcohol applications) and the oversize ports in the 1G allow superior inertial supercharging effects. The increased popularity of alcohol in the last few years constantly steered us in the direction of the fat 1G ports. If you want to build the world’s baddest 4G63 motor, all the numbers and the evidence gained through years of racing points in the direction of the 1G head.

With that being the case, the intake manifold needs to be optimized to feed these flow-hungry ports. Using advanced computer modeling techniques and after 7 iterations, we finally achieved the design we were looking for. From 20 PSI to 100 PSI. and from 40 lbs of airflow to 160lbs of airflow, the new 1G V3 cast manifold has equal flow distribution within 1 percent in each cylinder. That’s something none of the competition can even approach. In addition to unmatched flow distribution, the 1G V3 manifold offers reduced restriction and increased flow compared to all our previous designs.
