AS SOME OF YOU MAY KNOW, K&N ENGINEERING HAS HAD MY 8 SINCE MONDAY. I DON'T HAVE ANY OF THE DYNO REPORTS YET, BUT THEY CLAIM THAT WITH THE AUTO THEY WERE ABLE TO GAIN A MEER 5HP(PRELIMANARY) AND WITH THE 6SPD THEY GAINED 16HP. THE DIFERENCE OF COURSE IS DUE TO THE FACTORY INTAKE PORTS(4 VS 6).

THEY'RE KIT TOTALLY CHANGED THE SOUND OF THE RENESIS. ON THE 6SPD ESPECIALLY BEING DESCRIBED AS EAR PIERCING, MUCH LOUDER. NOT SO MUCH WITH THE AUTO THOUGH.

K&N STATES THAT THEY'RE KIT WILL BE UNDERGOING PRODUCTION WITHIN THE NEXT 4-5 MONTHS.

MORE TO COME AS IT COMES.:)

Do you know how much they going to charge for it?

Well, this should go a little way toward silencing the "Power Monkeys":D :D :D

WON'T KNOW TIL PRODUCTION IS COMPLETE

hmmmmmmmmmmm interesting

thats some great news, also it shows that once again, its not the engine, but the stuff around it thats in question

Pretty cool news, whats up with the CAPS LOCK BEING ON?

What about the other K & N products (non-kit) like the air filters that fit into the regular filter housing. BTW, I am not a power monkey but last night for the first time I hit the BEEPER at 8500. It made me realize though that there is so much more beyond 6000 rpm (my previous break-in limit) I hope someone dynos the car with this air filter "kit" and displays the data to quench the fury. It is been bothering me - not to say that I am not interested but rather that I bought something that is performance oriented and don't want to feel that it is flawed or something. I know that other owners feel the same way. We all like the car - I think of it as an affordable exotic per se but I also want it to be all that it is meant to be, to me and for potential owners or admirers.

Call me a pessimist but 16hp sounds like a big gain for just an intake. The factory air box has a HUGE filter and doesn't seem that restrictive. I expected that aftermarket intakes would generate 5hp at most. I will have to see a before and after dyno before I buy this one. For 16hp I'll be the first one on the list to buy one. I hope those are good numbers!

16HP...

Is that what Mazda says?

NO, THATS WHAT K&N DYNO REPORTS SAY.

REALLY?! 16HP?! IS THAT AT THE WHEEL?! IMAGINE ALL THAT POWER FROM JUST AN AIR FILTER? WHAT IS INCLUDED IN THIS KIT? HOW MUCH? IS EVERYONE ELSE AS EXCITED ABOUT THIS DEVELOPMENT AS ME? :D

HELLO MY PRETTYS... YES EVERYONE SHOULD OUTTA BE. KIT SHOULD INCLUDE FILTER, AND REPLACEMENT TOP HOUSING W\DUCT. :)

Does anyone have a pear or shade and ear muffs that I can borrow? It's hard to see and hear the yelling from RX-EVolved :p

I also want to know what the kit included and which parts of the intake was modified/replaced (such as ports/valves opening before the intake track, etc). I thought that, with the big filter the stock had, little or none horses can be gained by just replacing the filter.

Believe it or not I think RX has a stuck/broken caps lock key.. I'm up for a $5 donation for a new keyboard. :D

Y YES, IT'S TRU... I WORK 4 TYTEY WHITEY!

Here are some pics of K&N fitted RX8. K&N was kind enough to let me borrow the prototype intake for me to test and give them feedback on performance and gas mileage gains, if any.

As expected, the K&N intake makes a noticeable difference in noise level but not quite "ear piercing" as described above. I can only describe it as somewhat "throaty" and the noise overshadows the sweet rotary sound at higher rpm (maybe good or bad).

Performance wise, I didn't feel any improvement in throttle response as the stock intake was already very responsive in my opinion. Only 2nd, 3rd, and 4th gears were tested. Based on the dyno charts that I was shown and for what I can recall, most of the HP is gained at higher rpm (6500+) at an additional 10HP on average (peaked at an additional 16HP around 7500 to 8000 rpm). Lower rpm exhibited 2-9HP gain. I tried to convince K&N to give me a copy of the dyno charts but they wouldn't--damn I wish I had a photographic memory!!!

I would also comment on the gas mileage but I don't have a baseline of the stock intake. My last full tank, however, got me 18 miles to a gallon with the fitted K&N. I will have the intake for another week before I return it to K&N. Does anyone know where I can get it dyno'ed so I can post it on this forum? btw I live in Corona, CA and work in Irvine, CA.

This is exactly why I hate posting at forums. Smart ass replies like this one gets me irritated.

well i don't know about the hp gains, but it frickin' looks cool.

I don't know about the HP gain myself that's why I'm interested to get it dyno'ed myself. I'm only going by what K&N showed me.

Ooops...I failed to mention that the 16hp gain I saw was only 4th gear right around 7500-8000 rpm.

I see, they removed the stock box and get rid of the last intake track & port. Which explains the little gain from low RMP?

What I really like to see is if they produce the replacement filter piece and ultilize the stock box as well, which should keep the noise down for sure; then again, that might not prove to be useful.

why waste time sucking in hot engine air? cold air intake, that's the way to go!

I asked the K&N Engineers to see if cold air intake is possible and they told me NO since there's not enough room for it.

it's a matter of making room and deciding what's important. i cut a 3" hole next to my radiator in my FC TII, relocated my coolant reservior, and only removed my AC system to fit in my CAI. LOL

but i know other people who drilled the hole by the windshield wiper fluid tank, and sucked from the fender well, without removing anything.

it's just a matter of creativity. most old fox body mustangs suck CAI from the fender / wheel well.

What happens to the Variable Fresh Air Duct that opens @ 7250rpms? If it's disabled, don't you get a Check Engine light?

Nope, it's just a switch that either activate or release the vacuum actuator. There's no feed back from the actuator. I know for sure, the last actuator is vacuum shut closed at low RPM, and when vacuum is release via a switch, the port open. Very clever design I must say.

Would a K&N intake keep your warranty in tact? And I am aware that they cannot deny warranty claims unless the part caused the failure, but dealerships are largely more leniant with some performance mods more then others. So how would an intake affect it?

16 sounds about right. This engine likes to breathe. Even my RSX with cai was making about that much with intake.......I say about because i only saw others dynos. But for a ram air set up thats really good. I say wait for some of the others first tho.

Hopefully AEM comes out with something.

Keep up the good work, don't mind the trolls.

I know my dealer will not mind if I put in the K&N, as they are the oens that first told me to look them up. Highly recomended them too.

Do these guys mention any cost estimates for this when they were doing this?

Of course, seeing a picture of that intake makes one realize that it would take about $30 in parts to make it...:)

I think the only "trick" there is the hotwire sensor - the size of the pipe where the sensor is located probably has to be a fixed diameter. That, and a flange has to be fabbed to bolt it onto the pipe. Not rocket science, that!

Forget horsepower. What about torque? That's what I wanna know.

I didn't actually see the torque charts but K&N told me it's somewhere around 8 ft/lbs additional.

You can always install the stock intake back when you returning the car. :)

Just like an aggie - wanting to cut up a brand new car to do a job that K&N might have a little more expertise with... Better yet, it's a good way to save money right? Now where's my hole saw?

HP is mathmatically derived from torque so based on what he told you, you could calculate the torque gains.

16hp from an intake is unheard of. If anything you would be restoring lost power (clogged restrictive filter) an making a small additional amount from the additional airflow. I'm sure "tuners" are going to start making engine dynos with their intakes and people are going to "ooh" and "ahh." Sigh.

Seriously, I've been seeing this clown with the caps lock on typing in orange on this board...horrible.

I don't know if RX is a credible person, however, he has pics of the intake and doesn't act like a jackass.

in previous posts it has been said that his keyboard is damaged and he has not goten around to fixing it yet.

By the way, if it is a newer keyboard (2-4 years old or older) you CAN most likely wash it. Disassemble it. If the circuits are printed on plastic sheets you are good to go. Wash the topcover with keys, wash the plastic circuit sheets (but be sure to dry them with paper towels - no water spots allowed), and dry everything thoroughly. Oh yeah, and reassemble. :D

Do either of you guys (RX-EVolved or h8CAfwy) have a contact name at K&N? I would love to get my hands on an intake, post a full write-up on the forum, and post unbiased results. If it does in fact make 16 hp, which I believe it can, then I want the entire community to know. That would go a fair way toward shutting up some of the nay-sayers.

Bumpity bump ...

I have a guy making an intake very similiar to the k&n for my car, at will be ready next week. If interested in reviewing and testing one pm me.

So, h8CAfwy, got your dyno result yet?

Nope. K&N wouldn't release it in paper to anyone until production starts (maybe for legal reasons??? who knows). A little too late to get another dyno since I no longer have the prototype intake...didn't know where to get it done. They did tell me, however, that they might post a 12 HP increase on their website when everything's ready. Good news is that they also told me that I will be getting my free intake by sometime late September, a few weeks before they make it available to the public.

From the looks of the dyno sheets posted on this forum, if this intake removes the variable duct that opens at 7250 and improves airflow at those revs and higher, it could very well make that much power.
From those dyno sheets it looks like the motor is being choked whenever that duct is activated. This filter might simply "fix" that choking.

Very interesting...

12 flywheel HP, or RWHP?

12 flywheel HP, or crank HP?

I'm not sure, but what they've shown me are dyno sheets. Maybe somebody can enlighten me on this since I'm a newbie.

I would slap that on with my 500 mazda card. Any word on the price yet

If K&N can get a 12 wheel hp improvement over stock they will make a mint. Alas we'd need an INDEPENDENT dyno for proof imo.

I'm very curious to see the K&N intakes performance. I really don't doubt that they got 16 horses (let alone 12) from the intake. The engine does rev to 9k (well okay higher, but that's when the buzzer kicks in so I'll just say 9 ;)) so it will gain more power up top the better it can breathe. It's just like with a turbo car...the faster the air moves the more power you can get out of it...when an engine is spinning faster (revving higher) the more power it can produce.

Weird how a few people get mad cuz the engine is "short" on 9-10 hp...with $500 and free maintence you can get a lot more than 9-10 hp :). I'd take that deal anyday...

Now if only I could get one of those damn things already :).

the variable duct that opens at 7250 is vacuum operated and all you would need to do is remove and plug the hose to see if it stops the choking effect, I will tr4y it tonight and see if it does anything.

LOL, that's the second typo in a week, I'm definitely not batting a thousand, I meant flywheel and RWHP.

i think this ones alot nicer .

http://www.rotaryextreme.com/rx8intake.html

its a real cold air intake .

that one isn't ready yet

I'm waiting for the Rotary Extreme CAI too. I wan't to see dyno results on that one. That one seems like it would be better. Anyone else know when they are releasing that one. I emailed them a few weeks ago but don't have a date yet.

I finally received my intake kit from K&N last Thursday. I was told that it will be available for everyone in the next 2 weeks or so. As far as dyno results, just wait for it to be posted at K&N's website as I'm no longer gonna comment on it...hopefully we'll see some monkeys fly out of somebody's ass. :) :) :)

Not only the filter is huge, but it also looks good. The top and bottom cover is made out of carbon fiber--kinda hard to see on the dark picture. Overall, I'm pretty happy with it.

Really compliments the engine bay, I'll try to save my Mazda Debit Card :-) Will it be 2 weeks though? I hope so!...good pics.

Does it sound and do better? How much do other K&N systems sell for?

Yeah, how much?

What's the maintenance procedure?

I saw one at my local speed shop (the owners car who is going to sema) and the filter was really niced sized and it is SUPER light, the carbon fiber ends makes it look really nice too. The pipe looks nice as to be expected, looks like it would be easy to install also.

-Chris

Yeah, but what does it REALLY do to the power/torque curves? Generally speaking, I view K&N as a reputable company...but I'd still like to see independent dyno verification of any claims.

It's been mentioned that the stock intake is very well designed and uses cool air from the front of the car and has a marked ram air effect at speed, does the kn takes advantage of any of this or is it just sucking up hot engine-bay air?

More than two weeks have passed. No mention on K&N's site. Anyone heard anything?

i think it looks ugly the filter... I think I will replace mine with an HKS Super Flow one or greddy airinx... the K&N is absolutely hideous.

Dude, its a filter. Its not supposed to be pretty, its just supposed to work well. I've heard way too many horror stories about motors sucking in bits of oiled-foam elements from those HKS or GReddy, etc. filters. I've also noticed that if you pop the hood of a car at a show, with all the graphics and blinking lights it will be some elegant, color-coordinated thing like the HKS/GReddy/whatever, but if you pop the hood of a race car, you're pretty likely to see a good ol' K&N.

jds

when and how much?

16 hp from an intake that'll suck hot air from the engine bay!? What are you and the folks at K&N smoking? Anyway, why all this bother over a device that will raise you 2 -4 horsepower at best (if at all) and probably gum up your engine with its oil in the process? Just buy the washable Mazdaspeed filter (for LESS money) when it comes out and you'll save your engine in the bargain as well!

Where did that come from...gum up your engine with its oil? C'mon don't make shit up. K&Ns have been in use for years and years, I have never heard of the oil causing a problem.

Your quibble about the horsepower may be valid...it will be interesting to see independent dyno results.

Foam filters are usually soaked with oil just like the K&N. BTW, K&N makes a cleaner and reoil kit for their filters. I run a K&N drop-in in my '93 RX-7...

Filter is on K&N's site, priced at $289 direct from them. Will be cheaper from a dealer...

Is this Typhoon thing really the same intake we saw pictures of as a prototype? That seemed more like it should be in their FIPK series, not the Typhoon.

I am gonna have to side with the haters out there. THere is no way that K&N filter is gaining 16HP with it sitting open in the engine bay like that. It is sucking in a bunch of hot engine air. It doesn't even have a box or ducting from the scoops down below in front. I'd say 6-7HP max.

Get yourself a standard $65 K&N cone filter, get some PVC or 3"ID tube, and fab it up. I did it on my FC GTUs, and put it between the passenger fender and engine bay (Mazda already created a cold air box, where the brake ducting is!) and DAMN what a difference. Not only much higher gas mileage, but definite HP gains without question.

The secret though is that it MUST have a cold air source. It doesn't matter how much more air is sucked in, it matters how many more air MOLECULES it can suck in. Cold air has far more air molecules than hot air, so the K&N filter is doing just that, sucking a bunch of hot air.

Happy Rotoring,

Kurt G.
