I am posting it here instead of the performance section for two reasons.

One: it's a rumor

Two: it's a Drop in Replacement so LEGAL IN B-STOCK! :D

I'll let you know more when I find out

djmano

this thread is a bomb waiting to blow up once it gets to the aftermarket parts/mazdaspeed section.

AlexCisneros

yeah, I know... I figured there are fewer trolls in here and more people who want to do the maximum allowed in B-Stock

Ike

I'm curious as to why you guys think it would have caused contraversy?

AlexCisneros

There's always a troll that will say "oh yeah, the R.Ext is better"

When the point is that it will be a legal modification in SCCA Stock class

that and it's a rumor

BigAsian

Guess what, the RE will be better and you are stupid!

AlexCisneros

...and there's the Troll

Brando

He is a big asian troll!

djmano

i was never implying that it would cause controversy. i guess my word choice confused some people. i meant that if it was put into the aftermarket section which seems to be really hot with discussion then the thread woulld blow up with speculation and other talk.

AlexCisneros

well, just to cause some controversy... :D

I still think a drop in replacement will be the way to go, even if you aren't planning on staying in stock class. The airbox design for the RX-8 is pretty damn good, and if you notice the K&N and the R.Ext. borrow heavily from the design.

BTW: I had a K&N filter on my Eclipse (years ago) and actually picked up a couple of horses when I switched to the HKS intake (cone type). The design on it actually flowed better

I am very hopeful that HKS makes this intake soon as I think it will give you as much HP as the two I just mentioned (there's the controversy I promised ) and for much less :D

I just hope they do it before the Auto X season starts again for SEDiv. And hopefully my wife will read this and get me my HKS exhaust for Xmas
I've only been talking about it for the past couple of weeks and comparing it to my old one (Yep had an HKS exhaust on the Eclipse too, they just make stuff better).

AlexCisneros - I just love this post, nice job mis-informing people! Before you pull **** out of ur *** and post it for everyone to see, THINK!

OK - I HAVE PERSONALLY SEEN THE HKS INTAKE THEY ARE MAKING FOR THE RX8. SURE IT MAY NOT HIT US MARKETS BUT DOESNT MEAN IT DONT EXIST. I MEAN **** MAN, THEY HAD AN ARTICLE AND FEATURE IN OPTION MAGAZINE IN JAPAN SHOWCASING HKS RX-8 INTAKE IN THEIR OCTOBER FEATURE WITH THE BLACK RX-8 ON THE COVER, so please dont talk out of ur ***, thanks!

Genom

Efini, Your not quite as smart as you think you are. I'll leave Alex to explain why :D

AlexCisneros

wow, I'm left without words...

I guess Trolls can't read. Why don't you PM me your address so that I can get you a copy of Hooked on Phonics.

Toadman

Chill out, guys. Warning #1.

Ike

Wow, I guess you guys knew what you were talking about...

Djmano > Nostradamus

djmano

lol.....its all simple really. in every thread about aftermarket parts that goes longer than a couple pages, there are some words said here and there that people take offense to. sometimes by trolls, sometimes by fellow board members, sometimes by those who mean ill or mean well.

i guess one thing i can draw out of it is that we really love our cars so much that we can stand to argue on the internet for countless hours

lol all joking aside rx8club is my home away from home. i love my car and i love the board.

AlexCisneros

soo true..

still bugs me though. The rumor is that HKS will make the intake drop in, and since it is a legal mod for SCCA stock class I put it in here. According to efini8, he has seen it. I do not get the options magazine nor did I ever say they (HKS) weren't making it. I guess he just woke up on the wrong side of his bed and decided to NOT read the post I made.

And for the record, should HKS and K&N both come out with "drop-in" filters that are legal for SCCA stock class (I think if I keep repeating "legal in stock class" people might catch it before flaming the post), money is on the HKS unit. As I said earlier, I've been using HKS products for some time and I think they are the best on the market (my opinion :p )

BTW: Genom made a post called "multiple exhausts" I put together a little get together in Miami with him and a buddy named Armando.

You can hear both the HKS and the GReddy exhausts back to back. The HKS is a bit deeper. and after seeing both before being installed and hearing both after being installed...I'm saving my pennies for the HKS (sorry Yuri )

Now if only they would make a front sway bar
*hint*hint*

Ike

I agree, HKS is top notch for the most part, though from time to time the do come up with something that just isn't up to their usual standards. Just don't buy a downpipe from them if you ever own a WRX and you should be fine. Or a BoV unless you don't mind attracting random canines from miles around :p

Mod delete this thread, it's a Troll Hideout

Well here are just some things to think about and in no way am I adding opinions.

Mazda designed the stock airbox as a tuned chamber based on acoustic pressure waves. It's size and the size and length of the incoming air intakes are designed to boost power at certain ranges. The longer intake pipe tunes for a lower rpm and the shorter intake pipe tunes for a higher rpm. On the automatic cars, the only intake pipe is a different length still from either of the other 2 pipes implying that they did some research as to which car each one will work best on based on powerband and airflow requirements. Also remember that manufacturers design their intakes to be quiet as well. The total area of the intake pipes entering the airbox though is smaller than the area of the MAF or the throttlebody. Regardless of how well the box was designed and tuned, there is still a small restriction due to this area size and therefore some room for improvement. Different people will claim different amounts.

The K&N and RE kits utilize simple cone filters that replace the entire airbox. While these setups do offer less restriction than the factory airbox (remember the smaller inlet area) they also don't utilize the same range of acoustic tuning that the factory airbox has. How much more of a benefit each system has over stock is debatable and out of the scope of this discussion. The factory system received "cold" air from the front of the car ahead of the engine bay. The K&N system does not nor is it heat shielded. No judgement as to the effects posted here. The RE system is heat shielded and receives it's air through the same hole that the factory intake pipes enter through. Again no judgement here as to the effect. The length of pipes uses by both K&N and RE also DO tune the intake tract to a certain rpm. The longer the pipe the lower the tuned length rpm. Just remember that.

As a test of how restrictive the factory filter element is, someone needs to do 1 dyno run with no filter at all but still using the factory airbox system (please don't drive the car like this!) and a 2nd run with the element installed to find out the full potential of the stock airbox system. A good cone filter will have more filter area available than the stock filter does.

Just some things to think about.

I just want to add the factory filter element is quite large. It is infact larger than the equivalent unit in my previous LS1 powered car (5.7L) which developed 300+ rwHP.

The real proof should be in the MAP readings once we get an ODBII logger running.

I have seen dyno charts (other cars) showing no difference between 1) a new stock paper element, 2) a K&N element & 3) no filter.

The Mazda training manual I read mentioned a dislike for "wet element" type filters. I am a little surprised by that. I would have thought that a good filter in the stock air-box was probably the best way to go at the moment.

Personally, I don't like the RE intake. It is not even a CAI IMHO. It is beautifully manufactured, but the design is lacking. And a trusted friend measured a 2-3% increase in acceration times with the RE intake in place (i.e. slower).

rotarygod

My guess as to why Mazda would say that the car doesn't like wet filter elements would be due to oil getting on the MAF sensor and messing up the readings. Just a guess though.

AlexCisneros

What I have been saying for some time is that the Factory Air box IMHO is the best for this application. But as was mentioned, it is still more restrictive than that of a K&N, Green, or HKS Drop in element. This restriction takes away potential Horsepower.

As Rotarygod mentioned, the easiest wat to determine what the ultimate potential for the air box is, is to run it on a dyno with out any filter.

I still think that a drop-in will make as much power as the other current alternatives. As far as how much power...that's another story, but bang for the buck a $40 drop-in is better than a $140 drop in any day.

And as I mentioned so many times before, it is an improvement that will be allowed in SCCA stock class.
