Port and Polish Lower Intake Questions

Megan370z

I didn't port & polish the lower intake manifold . I only ported the HR plastic intake manifold before Z1 took the same idea after on the VHR.
I didn't had the chance do to a before & after dyno due to budget reason.

Z1 did with the VHR IM, and showed gain.

as far as the lower intake manifold , I feel you wont see much of any difference unless you also do the head. but at the power level the VHR does, It probably wouldn't be worth it. the VVEL isn't aggressive enough and then the VVEL already flow very well from factory.

After what happened to Synolimit thread on his research on this topic, we are still waiting on his finding.
