By: Holley | 03/23/2021 < Back to Motor Life Home

We dyno test a Holley Hi Ram intake manifold at Westech Performance with dual quad 4500-style throttle bodies, dual quad 4150-style throttle bodies, single 105mm throttle body, and an MSD Atomic AirForce with a 105mm throttle body. We go through the results to help you pick the right LS manifold for your next build.
