Compared to a lot of the custom manifold I've seen made where the user builds their own plenum/runners, this looks pretty well designed regarding equal flow to all 4 cylinders. I don't know if the runner length they choose is ideal, but it looks like it could be right for improving top end power. I'm interested to see how this works for folks. I've run VICS and now a squaretop, but if this new manifold outperforms both, I'll be upgrading at some point.

Skunk2 has never been good about providing dyno comparisons. Its usually a couple of dynos of one setup, in some sort of progression. Like stock vs stock with header vs header and stage x cam.
But they put some real R&D into their modern products (the old stuff was mostly just copying stuff that was already proven), so Im pretty optimistic. If the runners are the right length, the bigger plenum and better throttle inlet shape should make it useful on all setups. I dont think it will be like the Type R manifold or the old BEGi cast manifold where it hurts NA engines below 7k rpm.

If it doesn't make any additional power over the flattop, I'd gladly run an OEM designed and built manifold that is likely 10x stronger, and fits perfectly and could easily pass visual inspection in most states.
The only way this would be a market killer is if it makes a good amount more power. Just my .02

I think you severely underestimate the number of people that will buy it because it looks racey. That's their target market, actual racers not so much. This is why we haven't seen a manifold for a Miata yet. Honestly the drift crowds focus on the Miata lately has probably brought the platform on the radar.

I'll disagree.

Myself, I'll be waiting for 949's test. If its flows similar to a flat top, I'll keep my flat top until I get bored and finish my tuned ITB setup.

If it stock performs evenly with a square top but can be bored out it could have even more potential in it (someone has to prove that point). I think in that train of thought it could be a good manifold. I look forward to getting mine soon and reporting back as well.
I can say they have been nice to work with as well. Better than some companies. *shrugs*

Sorry for the threadjack, now back to your regularly scheduled topic.

This makes no sense to me. On numerous occasions I've gotten out the IR thermometer to measure the engine bay for a good place to put an intake pipe and IAT sensor, and the whole thing is **** hot on my mostly stock car. Ambient it is not. The back corner behind the IM is like 5 degrees less.

And regarding pricing on squaretop, the one I sold recently I got 300$ shipped for it. I would guess it would drop another 100$ if skunk will be even in performance.

It was sarcasm. Not that @Braineack is normally sarcastic or anything . . . .

So you have a new miata guy, comes in wants to boost and install parts. He sees a nice shiny new Skunk2 IM for $400, or an old grungy flat top for $425. He goes and looks and find that dyno's from multiple vendors at that point showing the Skunk2 is at least the same, and possibly in some cases better. I am pretty sure they will go for the Skunk2 the majority of the time.
Why do you assume this manifold is going to break? I can't find anything online from a quick search of broken Honda Skunk2 manifolds. So I am not sure why you make that assumption that all of a sudden their miata ones will break.
