ASM 5.7 and 6.1L Hemi Vortech Supercharger Kits

At ASM, We took a different approach designing the supercharger system for the HEMI motor because of the way the stock intake manifold is designed. The stock manifold has a tube that extends nearly half way into the manifold from the throttle valve flange. This design does not lend itself to simply installing auxiliary fuel injectors directly behind the throttle valve in the air stream like other supercharger kits.

On HEMI motors the stock intake manifold is designed to move air, not air mixed with fuel, so the auxiliary injector design was not an option. Our design eliminates the auxiliary injectors and instead includes eight larger fuel injectors to replace the stock factory units.

With a long standing reputation for exceptional engineering and while this approach cost a little more it's what needs to be done on the HEMI motors in order to get proper fuel distribution and engine reliability coupled with hi quality Vortech Supercharging components.

In addition, our design provides a large after cooler unit to maintain cooler air inlet air charge and reduce restrictions in the intake system (which further reduces inlet air temperature). The engine mounting brackets are precision CNC machined from billet aluminum and polished to match the supercharger, after-cooler and inlet ductwork. Spark and fuel management system consist of a preprogrammed, plug and play ECU that works with the factory installed ECU to maintain all the manufactures emission and sensor controls.

This system is designed to provide 125HP gain on 91 octane pump gas, and pulls hard through all gears without hesitation. An optional 36 month, 36,000 mile warranty on the engines oil lubricated parts.
