The Problem is that accountants are mixed in with the engineers when making any car. The K&N Filter flows more than the factory, because the factory will not spend the money to make a filter that can flow more and trap more. From what I've seen, both the typhoon and the R.Ext simply replace the air box with a similar air box and fit a conical filter on it.

IMHO, unless the conical filter feeds from the front, the air will flow into the box, swirl around, and then go into the intake. With the drop in it will hit a much larger surface area immediately (as opposed to delayed) and then funnel into the intake.

Typically a drop in does only add 3-4 hp on a Honda or other grocery getter. These cars aren't originally designed as performance vehicles. As such the CAI for them yield much more than a drop in. On Vipers, corvettes, and other performance cars, the intakes are typically designed to maximize ram air and. This is the case here. Additionally I have noticed that this is a VERY rich running car. It doesn't shock me that an improved airflow of any kind would yield so much power.

I'll wait for the Drop in, spend the $50 and then Dyno it. Then I'll post my findings.

 

I have the RE intake and have noticed some 'seat of the pants' improvements in overall performance. I haven't collected any acceleration data on the car with this in yet. However, the RE sound is definitely louder under full throttle. Not throatier, more 'buzzier' - sounds like a bunch of hornets. When you back off the throttle it goes away.

 

Ram air intake is still at the development stage. There are a few issues that need to be addressed. I can't reveal too much but I can tell you that the stock intake system is not a ram air one as thought by some people.

1. the primary intake duct is not facing the air stream. It's facing side way.

2. the secondary intake duct although is facing the front, there is a plastic piece blocking it.



I know the exact reason why it's designed that way. Let's just say to make a ram air intake that works at all time, we might not be able to keep the original price of $360. We might have to abort the project but then we are trying our best to make it happen and keep the same price.

Chuck,

Are you referring to the length of the intake tract and the VFAD? We know that it is because Mazda are utilising Helmholtz resonant tuning. What doesn't make sense is why the primary intake faces sideways and why the secondary intake is blocked by plastic. Neither appear to be in the best position to suck in large amounts of fresh cold air.

If you can explain the reasoning for that, we'd all love to hear it.

BTW I'm expecting my intake any day now. I'm more excited about it than I am about Christmas!

 

The length is not the main point. It's the position of the ducts. I can't really explain it until I finish the product or decide to abort the project.

Has anyone thought of getting a RE short ram and then getting the K&N filter element? Just a thought

 

Has anyone tried the SR Motorsports intake?

It looks as cool or cooler than anything I have seen and they are selling stand alone or as part of a performance package.

no one has posted having it yet
but damn its expensive

 

looks like an exhaust muffler

 

It is probably just a metal tube with a cone filter in it.

 

What is the anticipated whp gain for the ram air in comparison to the short arm intake systems? I am looking to combine a ram air/short arm system with a full header back exhaust and retune the ecu in order to gain the max hp possible. (do not have to pass emissions in the town I have my vehicle registered in) I really just want to get the whp of my rx-8 up to around 250. I think the greddy off road system, in combination with a ram air system and possibly the canzoomer type 2 or 3 would be the correct way to go, but I figure asking here would be a viable option since someone who is working on design of a ram air would be able to give accurate advice.

 

loving my re intake
quite and cant tell i have a intake during normal driving
but when punched it sounds like giant buzzing bee.

 

any idling problems yet like the k &n one had?

 

Not as much rough idling with the RE Intake. Do a search, this has been widely
talked about

BTW is very disrespectful to take our club logo and amend it like you have!!

 

You really ought to make your own Rohit, but anyway Racing Beat put a straight thought exhaust and intake and gained 2hp.

The main problem with all these intakes (Rotary Extreme is the best) but compared to stock their all pretty much only for audible purposes.

The reason being is they all are just a metal tube that supposedly increases air velocity but in truth their crap because all of them lack a Helmholtz Resonator. What that does is basically stabilizes the air going inside the combustion chamber. Without it the air is volatile as hell that makes it very hard to tune the car via things that read off the MAF sensor, i.e. Canzoomer.

This isn't a Camaro where can slap on an intake and exhaust and gain 25hp. Mazda didn't skip on high quality stuff. A promising mod for this car seems to be a light flywheel.

 

SO TRUE

 

wow all three of you can go to hell... not like it is his where is teh copyright matter of respect umm its the internet.. i changed it aronud it is no way affilated to him

 

I would buy this intake system for $200 to 260 US..... but....

ok, i like the look of the aluminium cover, but i just dont think it fits in with the rest of the covers.... kinda IMO makes the parts under the hood somewhat messy. although the indivual piece looks great, it stands out too much and kinda looks out of place.
i am waiting to see how the FG cover looks like.

 

i am going to believe the claimed hp for now... he aren't guilty of manipulatin the dyno until someone proves him otherwise.
so if i like the new covers, i will definately buy 1 (hoping the shipment costs wont be too dear)
