Just wondering, has anyone tried (or even notice) this intake?

Looks good, I wonder if...

 

really not going to give you a whole lot of power unless you get full turboback exhaust and a tune. they flow better but with that comes more dirt.

 

Flow better but more dirt? Isn't that the case with getting an intake for ANY car, whether turbo or not? How do you know how much power it will or won't give? Factory turboed mazda's gain 20hp from an intake alone, what makes the RDX different? Even you said factory cars run rich, an intake will lean out the mixture some, which in itself increases output.

 

i doubt the rdx will make 20hp on intake alone. realistically, 10-12 maybe. on evo's some ppl actually lost power by adding intake alone. every car's ECU will act differently to increase flow. that's what I was saying about getting a full turboback along with the intake to maximize extra power to be had in increasing total flow. you are not going to feel any difference with 10hp alone. better to spend that $ on a tune/reflash.

 

Just wanna let you know adding an intake won't lean out the mixture as the ECU will dump even more fuel to account for more Oxygen.

 

10hp is quite a lot, especially when you consider people spening thousands and thousands on their NA build (im talking specifically about the h22 off a lude don't have practice with other motors) with only a 10-20hp gain.

 

That's your opinion, I expect

mau: According to cp-e, they designed the MAF sensor plug on the intake to trick the ECU to thinking it's running on a stock box, so that you have gains without running the engine anymore richer than it is.

Go there, read the explanation on the mass air sensor for the mazdaspeed 3, then click on teh dyno graph link on the top right. They had a gain of 16hp, to the wheels..

 

Cool, please let us know how it works after you get it set up.

 

god i wish we had a catback n downpipe.

 

Ditto that.

Also agree with DatnVan. I believe DatnVan had a modified EVO. I had a 07 GTI with APR Stage II and intake didn't do a whole lot. When I read the CP-E thread, I was actually amazed that they claim 20 HP on the intake. I just didn't remember if it was 20 to the crank or wheels.

 

sfrederiksen said they did 16 to the wheels. i can believe that, just don't think you'll see those gains on the rdx. of course, you never know till someone dyno's.

 

A correctly designed intake should actually increase the flow of air into the engine. Engines like the RDX, that use a mass air flow sensor will see the additional air and automatically add the correct fuel to maintain the air fuel ratio. If the intake does not increase the airflow, then it is a waste of money.

Intakes that are sized differently from stock around the mass air flow sensor can make the car run richer or leaner in all driving conditions.

As the intake performs such a critical role in the determination of the air fuel ratio, any aftermarket intake should be tested in conjunction with the available exhausts (which tend to lean out the mixture) and in particular with the reflash we offer that:

- leans the fuel a little at mid to high load
- advances the ignition
- Advances the cam angle
- and increases the boost.

We have tested the reflash with the Church Automotive exhaust system. It runs a safe air fuel ratio.

No company to date, has an intake for us to test.

 

My personal take on this is:

More airflow into the engine "generally" makes a little more power, but if it is simply dragging more "warm" air into the engine, it may actually make the engine run less efficiently.

So I would definitely also upgrade the existing intercooler unit to a more efficient one (if one exists in the market, I doubt it). plus slap on a higher throughput cat-back exhaust system.

But if you guys are really serious on improving the engine power performance with these kind of mods, you might as well go the full shabang, and select those pieces carefully to make sure they are compatible with each other (not having one produce the power increase and the other to decrease it). That's why they have dynos to assist in tuning the engines.

Getting aftermarket mods is the easy part, but getting all the different mods to "jive" harmoniously together to generate a tangible increase in performance is another thing.

 

that's what I've been saying the whole time. high quality intake, turboback exhaust (downpipe, test pipe (or free flow cat), and catback) and a reflash/tune will give you safe, reliable, substantial gains in power. if you want to go a bit further, a larger O2 turbo outlet, larger/solid intake/intercooler piping, and larger front mount intercooler (if one exists or can be fabbed). a larger, more free flowing I/C will throw off your A/F ratio so best to get it before your tune.

the good thing about turbo cars is the modding steps are pretty much all the same.

 

I was at the Chicago auto show today and saw our engine on display. The exhaust does a 180 right out of the turbo into what looks like a pre-cat. The thing could probably get huge gains from an aftermarket DP. As for a FMIC. you'd have to run lots dead pipe to get it down there. It looks like there is space up top for a larger one though.

Has anyone data logged how quick the OEM IC heat soaks?

 

So has anybody tried this intake yet?

 

how does one go about getting both the CHURCH exhaust system and the proper reflash. i was on temple of vtech and church's website didnt see anything about it, maybe im just missing it.

 

I just placed a call at Church Automotive today and left a message. I have the same questions as you guys do. I'll keep you posted when I get a reply.

 

Please do. Like OP said, nothing on the Chruch site.

 

i'm personally waiting on CP-E's intake to come out. I have had some of the their products on my mazdaspee3 and i LOVED them. All american quality made stuff, and great customer service. here is a vid i found of the CPE Prototype Intake. Chruch's exhuast must be nice ... also waiting on info!

I forgot. Weapon R stuff was craptastic for a '07 GTI.

 

Any update from Church Automotive on the CAT-BACK availability? I looked at their website today, and couldn't find anything.

 

I actually just ordered mine from JC Whitney....free shipping. Can't wait to install, will post result (ie. sound, increased MPG etc)

 

Do keep us posted. Curious on your opnions.

 

Will do.... Do you have one...I am sure I am not the only on that is trying to avoid spending $300 for a CPE intake

 

...

 

Wrong.

The Hondata post just before this is several weeks old.

Hondata recently posted dyno runs with and without the CP-E intake, with and without the reflash.

I agree that the CP-E intake seems very pricie, given that this CIA is priced at about 50% less than the CP-E.

But I haven't seen any data (i.e. third party dyno runs) to show that this system is comparable.

If CP-E was even close to this pricing, I'd go with the CP-E intake.

 

Bottom line is that the dyno runs were perfectly valid for the comparitive dyno run testing, purposes Hondata stated, but potentially completely invalid for subsequent on the road use.

 

Potentially. Remove that word from all your remarks and admit your true thoughts. Now you feel better. Or maybe not so much. Make the rest of us feel better and cite your logic and sources. You haven't and can't because they don't exist except in your misinformed opinions. That's OK, because the world needs Naysayers too.

If you insist upon hiding behind the 'potential' safety blanket, rational logic dictates you cannot deny the reverse would be true - subsequent road use will prove better. Prove it wrong.

Oh.

 

Not only that, but you take phrases out of context and attempt to drive wedges the size of California redwoods into the perceived faults using your Porsche-driven(?) world-view. It isn't working here, WildWest. Different strokes, you know? I mean, who was it brought up a Miller-cycle engine in this forum? Not to mention more brainstorms from other eras.

What is eating your soul to the point you have to make such displays here? Let it out, be specific, because I'm sure someone here can either help you or knows of someone who could help you.

 

The "potentially" is there because NO ONE at this point in time knows what the dyno tests might find if a "drive cycle" were completed after making a configuration change and before the subsequent dyno testing. While my "guesstimate" would be a negative one I willingly admit I simply do not know what the results might be if the engine ECU were allowed to adapt to the various pertinent parameters for the "new" configuration.

And by the way most manufactuer's spell out what constitutes a full drive cycle and the reasons for same within their vehicle shop/repair manuals. Toyota, Scion, and Lexus manuals, all models/years are available to review for a fee at techinfo.toyota.com.

RATIONAL thoughts do not need to be proven, right or wrong.

 

Nope. But if I can avoid spending $300 for something comparable, then that is a no-brainer.

 

10 hp is a lot for an intake on a naturally aspirated car. 10 hp on a turbo is possible I guess. What you really want to do for a turbo car is get a new exhaust, as mentioned above. You could get 2x the hp gain from turbo car then a N/A car. Exhaust is the way to go!

 

so, did anyone get this intake yet ? i would love to see user opinions ...

 

If you are referring to the weapon r secret weapon intake, mine is coming next week sometime. I ordered it from JC Whitney b/c they offer free shipping. I wish I had access to a Dyno...On another note if you remove the resonator box, the tube before the air filter box you get to hear more tubro swooshing as well...the car feels like it has a little more pep, but could be mind over matter.

Has anyone else tried that.

 

what air filter did you go with ?

 

I got the weapon R intake on Tuesday. But my car was rear-ended on Sunday night. Everything is ok, car is sitting at the body shop waiting to be repaired. So have not installed the intake as yet...stay tuned

 

10-12 hp is a LOT of hp for just an intake! You would feel that. The throttle response would be better as well.

 

That sux....sorry to hear that Dan.
