LS1/LS2 Typhoon Intake MAnifold



This manifold is the result of over one year of development and testing and has proven to provide significant increases in power. In direct comparison dyno tests against a factory LS6 intake manifold, the Typhoon produced 17.7 more horsepower* at 6,200 rpm. It also makes more power and torque at low and mid-range engine speeds than other aftermarket manifolds. This design features a larger plenum volume, which makes the manifold suitable for larger displacement engines. The manifold has nitrous bosses positioned on the port runners. The LS1/LS6 version comes with either an 85 mm inlet or a 96mm inlet. Professional Products offers 80 and 85mm throttle bodies and 96 and 101mm throttle bodies are in development. The 96mm inlet version of this manifold can be used with either the stock 91mm LS2 throttle body or various aftermarket large bore throttle bodies. The manifold kit includes high volume fuel rails with stainless steel mounting brackets, stainless hardware, and a -6 AN stainless braided crossover hose. Additional fittings are also supplied that allows connection to the stock fuel inlet line.

Available in both 86 and 96MM. The 96MM will work with your stock LS2 Throttle body!


Professional Products Throttle Bodys



Professional Products offers this style throttle body in two sizes; 80mm and 85mm. The 80mm version is typically suitable for use on stock intakes. The 85mm size is for use on the Professional Products #52060/#52061 LS1 Typhoon Intake Manifold or other LS1 aftermarket intakes. These throttle bodies feature die cast aluminum construction and are O.E. quality units. Both models include an aluminum transition plate that bolts between the stock manifold and the throttle body. This transition plate smooths the flow of air when using the throttle body on a manifold that has an inlet opening smaller than the throttle body. These units are a direct bolt-in replacement for the stock throttle body. GREAT prices on these guy's!
