Jason brought us his 370Z equipped with an AT for some dyno comparison on the Motordyne M370 Intake Manifold. Tony @ Motordyne has taken the HR intake manifold that came equipped on the 07-08 Z33s and modified them to work on the VHR engines. The result is improved power & torque up to 6200 RPMs. The runner length is one of the largest differences when it comes to the two intake manifold differences. Results below.
