Removing weight from a vehicle is the same as adding power to it. Some of us will go to extremes to make sure this is the case. You probably know someone like that. Maybe it’s you. Rejoice. Wilson Manifolds has just released its Composite Modular Intake Manifold for 23-degree (Gen I) standard and raised-runner small-block Chevy cylinder heads. Made from a proprietary composite polymer for strength and durability, the manifold weighs about half the mass of a traditional aluminum casting. Best of all, the composite material rejects heat better than aluminum, and combined with a valley tray that isolates the plenum and runners from hot engine oil, maximizes intake charge density and power as well.
Wilson’s modular design incorporates a separate valley cover tray that features an internal front-to-rear water passage connecting the front and rear water crossovers for more even cooling and more power. The bolt-together spider (plenum and runners) easily separates into halves for modification. Swap the spiders from one engine to another or fine-tune your combination with different spiders. This manifold is race ready out-of-the-box. In fact, it has shown up to a 20+hp advantage over competitor’s race manifolds. It is an excellent manifold for classes that require a stock production type manifold.
