Got mine today! Install was quite straight forward with the instructions on the RE website easy to follow.
At idle, the car sounded normal, with just a hint of suction coming from under the heat shield. As soon as I jumped on the throttle though, the exhaust took over. The rotary extreme intake has definately added some decibels and a deeper growl to my cat-back exhaust.
On the road, it's still quite easy to drive around quietly when it's required, and at hwy cruising speeds, noise is more or less the same as stock. But open the throttle up and woah baby! From about 3000rpm the car really starts to growl, and it just keeps going all the way to redline. By the time you hit the upper rpms, you can feel the roar in your chest and through your foot on the accelerator. This intake combined with a cat-back is certainly not for those who want to enjoy some spirited driving without being noticed. You thought this car turned heads before....
In terms of performance, the car feels like it is pulling a little harder in the 3-6000 rpm band. It helps that the engine now has a much deeper and tougher note in this region than before, with it now sounding more 'torquey'. Overall performance gain over stock is hard to quantify without hard data, but like has already been said, now I really feel like I am driving a sports car!

I just read this entire thread, and I must say, that aside from the glowing reviews by owners of the intake, this thread is COMPLETELY lacking any scientific evidence that it increases anything but the NOISE the 8 makes, however good that noise is.
When are the producers (or any so inclined owner) going to step up to the plate with some REAL numbers, dyno, G-tech, Stopwatch, counting 1-2-3. Merely anything... or is this just a case of, well, just a lot of noise.
Sorry to be the sour note here, but where is the meat?

RE provided the graph but won't show us the data behind it.
From my experience with factory tuned intake systems vs. aftermarket intakes (on factory high performance cars) the aftermarket intakes give up low/mid RPM HP and torque for high RPM HP/torque.
I see no evidence of that on this RE supplied dyno chart. Also, by looking at the chart it looks like Mazda has done a very bad job in designing the intake system and I don't believe that to be the case.
I think that this intake system as represented by RE is a rip off.
It might offer some high RPM HP and torque (and intake noise) but at the expense of low/mid RPM HP/torque (my guess).

And your opinion is based on what?
I think it' odd that some people don't say much besides a firm belief in RE's intake and all that is RE.
I saw a 60 Minutes episode a few months ago that had people that worked for companies going into chat rooms and forums selling products and posing as users...
Just a thought.

...Sigh... here we go again.
Vince, you need to stop the attacks on Rotary Extreme in open forum. If you have issues with them, please take it up in a PM or somewhere other than this board. You have made your position clear over and over again, and I agree that people have to take any vendor's results with a grain of salt, but this has gone too far. Please consider this is your last warning.
Also, as Vince knows and many of you may be interested in, I am GOING to get my car dyno'd with and without the RE intake, but I have to wait for my oil cooler hose to be replaced before I can put that kind of stress on the car. This also means that I can not GTech-measure it either. See this thread for more info: https://www.rx8club.com/showthread.p...threadid=16968

Wow. Don't know what that was all about (above), but thanks for the HP graph. It's very encouraging, and should translate into some improved times. The fact that it supplies added HP over the entire range is a real advantage.
Looking forward, the intake in combination with your (soon to avail)SS free flow exhaust (other thread), we should be looking at substantial stuff :D , even wo CZ's stage 1, and then again it looks to be the perfect mod in prep for it..... :D :D

I am off to the dyno w/RE intake today and will let you know how it goes. How come I am the only one stepping up to the plate here? Seems that everyone else is all talk and no action.
I am building my exhaust tomorrow am and will re dyno afterward to see if there are any gains. The goal here is performance without obnoxious noise. More details to follow.

Thanks for the effort - it's only when independent guys like you take the time and effort to do these independent tests that we get any validation of the manufacturer's claims.
