FAST has developed the industry’s first polymer tunnel ram-style intake manifold, ideal for generating maximum power in boosted and naturally aspirated engines. Available for rectangular port LS3 and raised rectangular port LS7 engines, the FAST LSXHR FAST-RAM Intake Manifold features removable stacks of various lengths, so racers can experiment with finding which combination makes the most power in their application. Its polymer construction is not only lightweight and high strength, but also virtually eliminates power-robbing heat soak that occurs with commonly available aluminum intake manifolds. Testing has shown an average 30-horsepower gain between 5,000 and 7,500 RPM over competitor tunnel ram intake manifolds. The FAST LSXHR FAST-RAM Intake Manifold is designed specifically with boosted applications in mind and is rated for up to 45psi of continuous pressure. Compound fuel injector angle aims the spray pattern for ideal atomization, resulting in maximum power production and superior drivability. A reversible top allows for forward- or firewall-facing throttle body installations. The intake manifold also features two nitrous nozzle bosses per runner for clean and easy direct port system installations. Its 103mm throttle body opening can be port matched to 105mm.
