Best airintake?
 

Ok, so I´m a bit lazy... :rolleyes: What are, from your own experience) the best airintake for my 8? For increasing hp that is... I don´t care so much about the sweet sound and I know I can´t expect big gains...

They all sound loud. K/N is the worst by far. No HP gains when heat soaked. RE is good and SR is also good. May I suggest... search button. :cool:

RE is coming out with an intake, but not out yet.

Stay stock for now. Some people, like me, love the sound the K&N makes..

The best intake is the stock intake. Period.

I would have to disagree. The RE intake is by far superior to the stock intake as is SR's and the new Rotary Extreme intake. You just have to face the fact that the RX-8 isn't succeptable to bolt-on's that great regarding HP.

Here are soundclips, and pictures of the Borla and CTD´s Cat Backs Exhaust. Maybe a repost but if someone missed them before...

Why do you say the stock is better?

by what measure (except decibles) are those you mentioned superior to the stock?

i have the HKS racing suction kit, its pretty price it but i realyl like it. it sounds sic too with my greddy exhaust

I think RE already = Rotary Extreme. You might be thinking about the RB intake, that is Racing Beat. I will probably wait for the Racing beat unit.

The SR intake has the sexiest sound, IMO. Either that or no one with good recording equipment has recorded the RE, which sounded a tad ricey to my ears. The SR sounded like it resonated at a lower frequency, which wouldn't be surprising given it's big size. At higher RPM's it had a nice sport bike sort of sound.

In terms of power, none of them are going to deliver big gains.

i was just at the racing beat website. it looks to me like they are trying real hard to get the most power out the the b13 without making the driver go deaf. also i saw the K&N typhoon installed and i am not impressed with the prices for a few inches of pipe and a filter sucking air from the hot engine bay. no wonder it can't get above 10 hp! i think 310guy was right about stock being better just because what the aftermarket is Not capable of doing. and charging your first born for it! i have yet to see the RE set up so i can't really comment on that. if i am not mistaken, they claim about the same increase as K&N.

has anyone using auto exe Ram intake?! that intake just songs insanely sweet!!
and they claim it can gain about 5hp and 0.5kgf/m torque.. just wondering...

here is the "song track"

That last picture is false becuase air doesn't shoot directly towards the intake. In fact, there is no air flow to the intake. It is just sucking up dead air in a confined area between the bumper & frame.
Zoom: I base that on the fact that I had both the K/N and the Rotary Extreme intake on and I noticed an increase in HP with the RE, and with k/n I noticed a significant loss in hp and tq. RE and RB's intakes increase whp; not by much, but they DO increase whp. I just got a M3 2 weeks ago and the intake only makes 7-9 whp and it is $1,100! So $300 for 3 whp is not a bad deal :)

Troy was your RE intake a lot quieter than the K/N was on your automatic or did itproduce nearly the same amount of noise?

You make it sound like the engine is drawing in air from a completely sealed location. This is false. If there was no airflow, there would be no running engine. This area behind the bumper, while shielded from direct airflow, still has plenty of airflow to it. The stock system isn't a ram air system but it is a cold air system. There are many cars that run their intakes to the fenders. You don't see direct air there either. The dead air you are referring to is only dead in the sense that it isn't a true ram air system. There is no lack of airflow to the engine.

IMHO:

Do you want sound? Get any aftermarket intake.

Want the best "improvement"? Stay with stock.

Here's my story:

0-2000 miles = factory intake
2000-7000 miles = K&N intake
7000 - currently (about 7400) = factory intake

Without a doubt my car responds so much better with the factory intake.

All this crap about ANY hp gain is at or near redline. (Go ahead, look at the "dynos.")
Do you drive at redline all the time? No, so save your money if you want an intake to "increase" hp. Only get an intake if you want the sound (and possibly lose low end torque and throttle response like me).

I've seen both sides of the coin.

End of my story...

If you don't have definite indisputable proof or this in some fashion then you don't have an accurate statement. You can't feel 3 rwhp. No one can. I know for a fact that you can't prove your claims since you also claim the Racing Beat makes more power than stock. You have never seen one since it hasn't been released yet. I don't doubt it will gain though but I do doubt your statement.

I will give you credit in one aspect, I do like the cold air ducting from the front of your car. I don't like the material you used to do it though.

who's they and who's on first?
