TW' THERE'S NO BAD MECHrn WAY TO BE BLOWN i m

The classic drag racing combination is a bug-catcher air intake atop an injected, blown race Hemi. By design, the Roots blower is difficult to intercool, but there are some manufacturers making air/water intercoolers that are sandwiched between the blower and intake.

To properly meter fuel, Roots blowers that are mechanically injected engines use a barrel valve. This is what you see the crew chief adjusting prior to each Top Fuel quarter-mile pass. Most street cars use either electronic fuel injection or carburetors with their blowers.

Roots blowers might be considered old-school to some, but they're still widely produced, available in kit form, and can be a great way to get impressive power numbers from the engine in your classic or modern Mopar.

Most Roots superchargers on classic Mopars are topped with one or more carburetors. These systems are actually fairly simple to install, and can be very reliable if set up and tuned properly. So if over the top looks and power are your style, a Roots supercharger may be just what you need.

The latest Roots blowers with "high-helix" rotors are even more efficient than the original design, and reliable Roots supercharger systems are now available for modern and older Mopars, both carbureted and fuel injected. By design, the roots blower provides instant boost for incredible torque and throttle response, even from an idle. Race units are generally set up for mechanical fuel injection to handle the large volumes of fuel required, and injectors can be mounted on top of the blower in the injector "hat" (helping keep the mixture cooler), in the intake below the blower, or in extreme cases, injectors can be installed in both locations. Roots superchargers are also compatible with electronic fuel injection, and small roots blowers can provide big power increases on otherwise stock late model Mopars. Another common setup for older cars is dual carburetors on top of the blower, though this method generally requires cutting a hole in the hood, allowing the world to see your massive display of power.
