Racing Beat’s Holley Intake System Kit has proven over the years to be an extremely popular carburetor upgrade, with very “streetable” engine smoothness and drivability characteristics. Fuel economy is comparable to the stock carburetor under similar driving conditions.
Each comprehensive package includes a cast aluminum high-rise intake manifold with a vacuum source for power brakes, a Racing Beat-modified Holley carburetor (465 CFM), foam air cleaner and canister assembly, throttle, cruise control, metering oil pump linkages, automatic transmission fittings, and appropriate gaskets. All emissions control fittings are eliminated.
With the exception of the 1976-78 RX-3 and the 1979-85 RX-7 engines, this kit increases engine output by approximately 20 HP with the stock exhaust system and approximately 40 hp with open headers.
If the kit is installed on a 1976-78 RX-3 or a 1979-85 RX-7 engine, a header must be utilized or power will not increase significantly over stock horsepower output. With a header installed in conjunction with the Holley Intake System on these engines, power gains of 20 HP are typical.
The carburetors and manifolds used in these Holley kits are also available separately in the “Holley Components” section. Also see the “Intake” section for other related intake components.
Note: Installation of this kit requires use of a high performance fuel pump delivering 6 psi @ 20 gph.
