Z1 Ported Intake Manifold Before and After Dyno Results
 

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.

Can you post the dyno sheets please?

Also do you have after market headers installed? Or are you still running stock Headers?

sub :)

Still stock headers. I'll update the original post with the dyno sheet.

Did the bay temperature change noticeably when the doors were open?

Subbed..

Yes it was a 10-15 degree change according to the temp monitor on the dyno..

How much Torque did you end up making??

Didn't even think to check it. I can have my tuner send me my graphs.

Ya please do...

Update on manifold
 

Hey. Hope all is well in your world.

I own a 2016 base Z, MT. I've done a Stillen Gen 3 intake and FI catback.

Close to ordering FI HFCs. Planned on doing a tune at this time.

I'm curious if the manifold is really worth it and if so I'd do HFC, manifold and tune together.

Thanks for any feedback.

If you are staying N/A I think you got excellent results on your dyno congratulations.

was this just with the upper plenum or with both the upper and lower?

Any results after the Hi Flow Cats installed?

Just the upper.
