Founded by Phil Weiand, the Weiand Company began as a performance parts warehouse in the 1930s, selling various speed parts.
The first product, the 'High Weiand' manifold, was manufactured and marketed in 1937, being the first aluminum intake available.
In 1949, Weiand introduced a series of 'tri-power' and four 2-barrel manifolds, and shortly after WWII, a line of aluminum cylinder heads for flathead Ford engines was debuted.
The 'Drag Star' line of 'log' manifolds for Hemi engines was introduced in 1952, and in 1957, Weiand developed complete blower drives for the GMC 6-71 supercharger.
The first dual plane, 180º intake, known as the 'Colt,' came from Weiand in 1965, followed by the introduction of the 'Hi-Ram Manifold' and its patented D-port technology in 1968.
The popular 'X-terminator' single plane manifold series launched in 1972, and high-performance aluminum water pumps were produced by Weiand the following year.
In 1974, the 'X-CELerator' series of performance single plane intakes was developed.
The first models of the famous 'Team G' series of 360º racing manifolds were introduced in 1978, and a year later, Weiand's 'Action' series of high-performance replacement manifolds debuted.
In 1990, Weiand became the first OE supplier of superchargers to Mercury Performance Marine, and over the next three years, the 'Stealth' series of high-performance dual plane manifolds was designed, the 'Pro-Street' supercharger was certified 'emissions legal' by CARB, and Weiand received the industry's first 'E.
O.' for an intake manifold.
To make more power, you have to get more air into your engine.
