“There are several reasons for wanting to upgrade an intake manifold,” Little said. “The prime reason is to extract more power from the engine. A custom build really requires an optimized system. If you’re changing the camshaft for a more aggressive profile, or porting a cylinder head to get a few extra horsepower, you will want to look at matching the intake manifold to the rest of the build to get the most out of it.”
Chevrolet Performance produces manifolds for Small-Block, Big-Block and LS/LT/LSX applications. Regardless of the type of project, or even starting point, there is one specifically designed for nearly every type of build. There are options designed for a truck application to build torque for instance, or to package in a smaller space. Supercharger intake manifolds are also an option.
According to Little, all have been designed to consider the functional needs of the customer and validated to work in a wide variety of operating environments.
“We’re not just trying to make the most power at an elevated engine speed,” Little said. “We try to engineer solutions that provide a great power and torque curve with the driveability that our truck owners expect and the power that a Corvette driver lives for. We don’t want to trade off absolute power for low-down torque.”
All of the manifolds are produced to GM’s exacting standards, but the newer LS and LT manifolds are all developed utilizing computer-aided engineering tools like Computational Fluid Dynamics and Finite Element Analysis.
“This enables us to provide a lightweight, cost-competitive, yet functionally strong part that is validated to production requirements,” Little said.
For those ready to upgrade their project, or to tackle a new one, these intakes are sure to fit the bill.
