All of Professional Products intake manifolds incorporate many new features not found in competitive models. Some of today's most popular manifolds were designed 30 years ago and the makers have never bothered to update the tooling to include many of the new features desired by performance enthusiasts. Professional Products have engineered those features into their manifolds.
Common Features Include - Rear water crossover passages (Ford) - All ports very accurately positioned due to advanced casting techniques - Every tapped hole in each manifold is chased with a tap to clear polishing residue and assure the threads are not damaged - All polished manifolds are meticulously hand polished to show quality
The Typhoon manifolds, along with the similar CrossWind, are the most powerful dual plane manifolds available for a small block Chevy. For non-pollution controlled street machines, these are among the very best manifolds you can use. They feature a square bore carburetor flange, nitrous bosses, four corner water ports, and dual distributor holddowns. These manifolds are approximately 5/8" taller than the Cyclone series. On medium horsepower engines, dyno tests have shown that this manifold comes very close to producing similar power and torque numbers as our Hurricane racing intake manifold.
