Danger to the manifold! An intake manifold shootout?
OK so with my recent kerfluffle about intake manifold benefits, I would like to propose the following!
Intake Manifold Shootout!
I'll pay for the dyno time to test out several 1.8 manifolds, back to back, on the same day.
Potential Challenges:
Benefits:
We'll have empirical results!
Method:
I can use my car, or we can use any turboed car. I say 1.8 because that's what I have. We could do the same for a 1.6 as well too though. I think higher boost would improve the measurement resolution as benefits/drawbacks would be more pronounced.
And, if anyone else is interested in doing this, I would be glad to ship my gutted mani to you and contribute $ to the dyno time for the shootout.
Anyone interested?

Potential Challenges:
- This could possibly be troublesome since coldside IC piping may need to be done as well but I may be able to figure out some sort of multi-coupler rapidly-reconfigurable setup.
- I only have the stocker and a gutted one right now. I will need to gather up a few loaner parts for this shootout.
- We would have to do a little fuel retuning between intakes since the airflow (hopefully) characteristics will be different and we will want the AFRs to match up.
- We might need to mess with the throttle cable and may have different throttle bodies depending on the intakes.

Gotpsi? is the screename. Gotpsi? intake manifold build :https://www.miataturbo.net/showthrea...ntake+manifold

Watching this thread like a hawk, those manifolds by Gotpsi? are nice. If there's numbers to back them then so much the better.
As for TB, I'm wondering if I should stick with the stock or go with a bigger one? I am just hoping those who do these tests be consistent with the TB selection too
