Third-party Evo Pro Series Intake Manifold dyno test results courtesy of Road Race Engineering:

Road Race Engineering's technicians fitted their test vehicle Evo VIII recently with Skunk2's new Pro Series Intake Manifold and subjected it to their Dynapack dyno for testing. With the manifold bolted on and no other changes made to the engine, the 4G63 laid down an additional 21 peak whp and 5 lb-ft of torque. Power jumped from 485 whp to 506 whp while boost dropped by nearly 1.5 psi. The slight boost drop combined with the impressive power gain demonstrates just how efficient the Skunk2 manifold is.

Designing an intake manifold that can produce broad power gains without sacrificing low-end or mid-range power is challenging. With more than ten years of experience designing, testing, and manufacturing intake manifolds, Skunk2 has the answer. Skunk2's Pro Series Intake Manifold is the best solution for Evo owners utilizing the factory turbocharger or medium-sized turbocharger upgrades who are looking for all-around power gains. Most intake manifold upgrades offer impressive top-end power gains but at the expense of low-end and mid-range power. Not Skunk2's. You don't have to sacrifice one for the other. Imagine what the Pro Series manifold can do for your Evo.

Road Race's test Evo features a 2.3L stroker engine, custom exhaust manifold and three-inch exhaust, Garret 7036 turbocharger, Perrin front-mount intercooler, HKS camshafts, and runs on E85 fuel.
