Z1 Ported Intake Manifold Before and After Dyno Results

ajcool2

Finally got the chance to do a real before and after dyno with one of my parts. I did 3 runs with no changes, 3 runs after the manifold, 3 runs with some timing adjustments then we opened the bay doors and did a few more runs. My other mods are Art pipes, Ark Grip Exhaust, NST Pulleys, AAM intakes and uprev. All of the runs except the last 3 were done with the bay doors closed. Here's a quick summary and video of the runs.

Bone stock = 287whp
Baseline after mods before manifold = 322whp
After the Manifold with no tuning = 324whp
After Manifold with tuning = 329whp
After manifold same tune and bay doors open = 340whp

Here is the video.
