We Need Your Feedback on Our Mazdaspeed Intake Manifold

[Mazdazilla6]

I'm not sure those holes are for injectors. I don't think we have enough space between the front of the mani and the rad fan for injectors to be put horizontal like that as well as having a rail above (further towards front) them.

My guess is that they are for meth nozzles since they can be had as 90* nozzles and do not take up much space.

Fair enough. But my reasoning for the purchase was the hard data that showed how poor the stocker was. and beauty is in the eye of the beholder. thing has some sweet ass welding and excellent finish. professionally crafted for sure. dont knock it

as far as Honda and Honda tuning. well i wont get into because i dont want to be banned. and you are of course just guessing about both subjects.
i am very pro CS manifold.

good points

[speedfreak44]

Again as I have said previous...everything is and will be speculation until hard data is provided. Thanks.

[shaneski]

As others have said, some flow data etc to prove it is worth buying then i will hand over the money for sure.

For you guys questioning the clearance between the manifold and the radiator. There is approximately 3.5" from meth port (yes those are intended for meth) location to the fan shroud for the radiator. The CS manifold is a very compact package even compared to the OEM mani.
Note: I also have the CS radiator installed in my car which pushed the fan shroud back ~0.5" due to the thicker core. Yup Gen2 works in Gen1 with a couple tweeks

Numbers will come soon enough guys...enjoy the picture!

[speedfreak44]

That looks great. Love the space it makes and cleans up everything.

I know this is nit-picky, but on that top right bolt, any chance you could make it such that a ratcheting wrench could fit on there easily?

That has certainly been a pain point for us. V3 will still require the use of a stud for that location, but clearance has been improved significantly.

How is the angle of attack from manifold runner to runner in the head? A nice smooth appropriate 180* or hard, sharp 100* like, "the other guys"?

Nice and smooth...ooohhh yyyaaa

[JgamB]

I made a mistake looking at the runners myself, thinking the tumble to the cyl head was incorrect. If you've ever pulled the IM, it's an obvious slope down into the combustion chamber, and this design makes a helluva lot more sense than firing straight in.

[Enki]

Know what this mani really needs? To be installed on more test cars.

[Tokay444]

Or installed on a head with valves and cams and flow benched against "acute angle mani", and a ported stocker.
I hais a flow bench with velocity meter, and a head, and cams, and a ported stocker...
See where I'm going with this?

[Raider]

Flows and such are nice. But what I really need to know is....will it blend?

[speedfreak44]

How much of an effect does flow angle have on a forced induction system? I know it is crucial on NA but I thought FI had slightly different rules to follow? School me please

[Dimenus]

How's the low end throttle response with VTCS gone? I always thought that the stock mani without VTCS sounded like a hooker choking on a pile of dicks.

agreed. i have my hood off and ready to get to the injector seals repair /upgrade from CS. Seeing this and looking at the stock setup is miles different This is a tidy unit! where was this two years ago ?!!!

My man is right. The idea is great. The affordability and competition is great.

HOWEVER!

Results are needed. The testing needs to be flow benched so recorded data is available to the public to see. It also needs tested on a variety of set ups. Stock head with this manifold VS stock head with a stock pnp manifold - built head with this manifold VS built head with a stock pnp manifold. We already know the results of the jmf.

I do entertain the idea of the meth though. I think more tuners should give their two cents on the location of where the nozzles would be fitted.

Other options you should include are shaved manifolds for people running FMIC and taps for PI.


Yet, I am just another person on this thread saying the same shit as other people. Get on it. And send brock a manifold - I mean, he did hook it up with the seals.

Or cold weather? or cold weather high altitude (I have both and would love to test this...)

[Tokay444]

No one ever flow tested a jmf on a head.

I thought they were all being ‘tested’ when installed?

[GCPhotographers]

@CorkSport; I don't want to be the one to re=open threads but is there an update on this product?

[MS3Shadow]

Is it a "2 weeks" again?

or do we need to unleash cats to make it progress?

Very interested, it's on the pricey side, so it would be nice to see some testers running it on a bunch of different setups. As with all stuff CS I'm sure it ends up being worth every penny, and it sure does look sexy.

moar catz.

I would hope they will have color options as well.

[MS3Shadow]

Color options would look very nice.

You can have it powdercoated yourself any color you want.

Are there any flow bench numbers relative to the stock/stock-ported manifold, and any of the other competition out there?

[aromig]

Soooo..... we have the Puppy Turbo.
Kitty Intake Manifold mayhaps?

Shamless pic of cat in a Mazda for good measure:

Not that have been done properly, but MAP flow benched the stock and their porter manifolds, à la carte.
