Is it true the K&N Typhoon intake actually decreases your HP?
Is it true the K&N Typhoon intake actually decreases your HP?
I been reading alot of reviews, People say they actually feel like they lose hp after they install the intake
lol people who need to get a life telling people who have a life to get a life. classic.

it increase hp on a dyno because the hood is open and there is a fan (always) blowing directly at it.
on street, u probably lose HP if u use it with the stock VFAD, cuz u will not be able to get air anywhere other than engine bay.
if u use it with RB duct however, you will not lose hp when moving in fact u will get some hp, but don't expect magic numbers.

stone...just ignore him seriously...there's a set of rx8club elitists who think they have the right to judge which threads should and shouldn't be created. Don't try and limit your experience for them. Let the quality people here help you out and leave the rest alone. Don't even bother bringing yourself down to their level. Stay above it.
Regards to the typhoon, I had one installed and actually was measuring the numbers being reported by the MAF (through OBD-II) and was getting less airflow over stock. I felt the loss in power with the typhoon too. I put my stock back in and removed the resonators. It restored my sound I had with the typhoon.

Stonerexpress5, lighten up. You asked a question on a open forum. Expect there will be positive and negative responses. That doesn't mean that they are haters or dic's. You need to start thinking of it as constructive criticism. The negative criticism is to the product, not to you. Unless, you try to defend your purchase to excessively without regard to what others have found.
Something to consider with cold air intakes...
Mazda etc spends 1000s of dollars resonance tuning for the correct
flow at a specific point on the RPM scale usually dictated by marketing.
Changing anything could alter this point of max flow and make the
engine feel weaker. Also these changes will affect throttle response
Resonance tuning is like the tuning the port in a speaker enclosure
at a specific point the air in the column begins to vibrate or resonate
at max flow and after this point it slows down flow. Ford and GM
used to put funny little screw on bottles to add volume to the CAI to
assist in tuning.
Ive been tuning speaker enclosures for years and was totally surprised
when an engineer from Porsche explained how important this tuning
actually is at high RPM and it takes months of messing around on the
dyno and real world driving to get it right. Every bend or shape change
in the part affects flow and the frequency. Ram tuning does factor into
this as well but not to the degree it does in the intake manifold.
Designers want a certain look or choose a diameter or shape to make
the engine compartment look the way they want...
Naturally the engineers want the largest diameter possible to allow the
most flow
I have a frequency generator and a test enclosure of a specific volume
2 years ago i tested a factory CAI and compared it to an aftermarket
offering... the aftermarket CAI resonated at a higher frequency therefore
sooner and added throttle response earlier in the RPM range but actually
flowed so much more air that it did as promised..
imagine if the aftermarket piece was tuneable for your specific build or
the way you want it to feel ?
my 2 cents...
so many times i see posts about changing stuff to enhance the look
or sound but no thought is given to whether or not it hinders or
enhances performance. Of course to each their own lol

I've had mine for years. It was the 1st mod I did to the car. I noticed no difference other than the intake being louder. Mine was modified this past summer. You can check out pics in my profile.
K&N Typhoon intake actually works as a hot air intake since its getting the air from the engine bay. The stock intake gets the air directly from the outside so it actually is a cold air intake it self. The mazdaspeed and AEM offer a bit of improvenment to the stock intake.
