Find me a time when a manufacturer, claiming realistic gains, was blasted for not providing dynos.

Come on, it's pretty simple -- you make a claim that's in line with what people expect and you don't have to prove anything. You make a claim that's outside of what people expect and you better back it up. People know what to expect from mods now, if it's outside those expectations, people will want proof. If it's within those expectations they won't (or they at least won't be "blasting" you for it).

It doesn't matter who you are, if you come onto these Forums and claim you're going to sell an Intake that nets 3whp, virtually no one's going to ask for a dyno. But if you come on here saying you've got an intake that nets 15whp, you're going to get "blasted" if you don't have a dyno.

It makes no difference on what company you're talking about or even what car you talk about. If I go to the LS2 Forums and I say I've got an exhaust that nets 10whp, no one's going to bat an eye, because that's perfectly normal (a bit low really) and well within what people expect. If I said it gave me 40whp, people are going to be demanding Dynos.

Unless I've missed something, I've only ever seen one back to back test and that was Polak... and the bottomline there is he made 177 hp stock and 178 hp with REVi/REV8 https://www.rx8club.com/showthread.p...ight=revi+dyno .

But wait, nobody is critical. People are actually jumping for joy that a random dyno blip produced ~10hp gain in one dyno though.

I've seen no evidence that the ram air does anything except lower intake temps - thus making it a cold air extention. If anyone else was advertising "Ram" air, people would be jumping up and down (as they were before it came out) that something like that does not work - actually, ironically someone posting in this thread has a page long diatribe pre RB ram air on how ram air does not work but has said nothing critical since. Hmm... i wonder what changed.

The only data I've seen was Xyntax's post in 2nd gear runs which show the ram air produced no more airflow then without the ram air (despite some people claiming it produced a "positive pressure" at 65mph - too bad thats probably cruising at 65mph where it doesn't matter with a throttle 70% closed).

I was reading their description, and unless I missed something there were no mentions of a "ram air" effect from the REVi intake. On the Ram Air Duct unit it mentions the cold air effect far more then "ram air"

Whether it's cold air or "ram air" hp gain is hp gain to me. A CAI is fine with me.

Racing Beat's Descriptions :

Ram Air Duct :

"Racing Beat offers our Ram Air Duct for use with the Racing Beat REVi Intake Kit. The inlet of this duct is positioned in the mouth opening of the Mazda RX-8 to allow cooler ambient air to be force-fed directly into the REVi intake tract, converting your intake into a true "cold-air" intake system!

Designed by Racing Beat, this high-density polyethylene intake duct mounts under the nose of your RX-8 and directs air into the inlet of the REVi Intake Kit. This duct can also be used with the stock intake box or aftermarket intake kits to direct cooler air into the engine compartment."

The REVi intake

"The major components of the REVi Intake System include: an OEM style air box assembly, custom-designed K&N air filter unit, aluminum mass air flow sensor tube, and a tuned-length air inlet horn. Unlike the majority of the aftermarket intake systems on the market, the Racing Beat intake system retains one of the important mesh screens to aid with the even distribution of airflow across the mass air sensor. The inclusion of this screen minimizes the possibility of “rough idle” issues that may occur if both stock screens are eliminated.

Working with the design team at K&N Engineering, a high capacity air filter was developed that allowed us to position a tuned-length intake horn inside the filter body. This filter design allowed us to fine-tune the length of the air horn to maximize the performance potential. We have noted that most aftermarket intake systems for the RX-8 incorporate a large air filter, which is then connected to the intake manifold with a length of plastic or metal tubing. In many cases, the size of the filter that has been selected will dictate the length of tubing required, severely limiting the critical tuning importance of the air intake tube!

The REVi intake system addresses one of the most common complaints that we hear regarding aftermarket intakes for the RX-8 – extremely loud intake noise! Although a simple unshielded “tube-and-filter” intake system may produce respectable top end power, the noise levels that are produced are unbearably loud. During initial testing with one of more popular aftermarket units, we recorded a full-throttle sound level reading of over 90 db inside the car, with the windows rolled up! Compared to the stock sound level, we believe that you will soon tire of this type of “rocket-racer” intake buzz. The REVi intake produces a much more modest intake sound with only a 2-3 db increase over the stock system. As described on by one of our prototype test volunteers, “This intake is definitely louder than the factory unit, but not unreasonably so. It actually sounds deep and pretty darn good.”

Where are they exspousing that they have a "ram air" effect ?

Its called a Ram Air Duct. Its not called a Cold Air Duct or Racing Beat Air Duct or even a REVi cold air extension. By calling it and advertising it as a Ram Air Duct, they should be responsible to show it does have ram air effects like any other manufacturer that would come on this board would have to.

Sigma

They call it a Ram Air duct because that's exactly what it is. I wouldn't know what else to call it myself that would make its' function and purpose known just by hearing the name. But, despite what they call it, they claim it only gives "true 'cold-air' intake' results. No where in the description does it say it gives ram air effects, only that it "force-feeds" air directly into the tract. Besides, there's no way to test ram-air effects on a dyno to determine even if there was any sort of ram-air effect.

Now you're just digging.

And for the record I don't, nor ever have, owned any Racing Beat products.

so it would be perfectly acceptable if I would make a cold air extention and call it a "Forced Induction Intake" or "Supercharger" as long as in my little descsription it doesn't say it increases pressure?

Would you be happy if you would order a "Steakburger" at Burger King and out comes a chicken sandwich with the explanation "we only said it was big, moist, and good tasting... not that it was made of beef"

Well, this thread has evolved into quite a mess since I last posted. I have never said anything negative about RB, I am not a RB bigot, nor an advocate against Racing Beat.(as Fanman would like to believe). I AM against what can easily be refered to as SPAM. When someone starts a thread asking about one product and you jump in with an essay sized post about a product that has absolutely nothing to do with what he is talking about, you are technically spamming the thread. So I will go on record by saying that I am an advocate against anyone (like you Fanman) that buries anyone elses threads with your commercials for other products. I dont care if they are paying you or not or if you are simply dating the freakin owner, thats a non-issue.

(exaggerated example)

Me: I like pizza.
Fanman: Pizza?!!! You could save the money you spend on pizza and buy a RB exhaust
Me: But I am interested in pizza... I'm hungry.
Fanman: You're just a RB bigot! All I'm doing is telling you that you can get a great part like this... (post goes on for 2 pages)
Me: Well, I'm sure they make good parts, but were talking about pizza here.
Fanman: (another off topic post that tries to skew the conversation into making me the "bad guy")

Stop acting like little girlies! All I wanted was answer to my question, sheeesh! I keep thinking somebody may have posted some more enlightening info for me, but instead it's been hijacked into some RB good/evil thread!

hahaha... keep going please, I'm very entertained... hahaha

The guy asked about pullies. I said spend your money on something else like the RB air Intake. Your example is NOT exagerrated it is absurd. The price of pullies is approximately the price of the RB REVi & Ram Air Duct. Were you too shallow to read my next post that said I really don't care what you get, but you shouldn't get pullies. If you read my next post it said get an RP performance hi-flow cat, get a Richard Paul Short Shifter, just get something that works. Hell, even from the same company get the SR hi-flow cat unit. But you got mad at me because I said that something that you have on your car doesn't work. So, if somebody is looking for hp gain & wants to get a cat back exhaust, but people on this board tell him that it won't give him hp gain, but instead to get a hi-flow cat, or a midpipe, or an air intake they are spamming ? You keep on dwelling on one point..it's bordering on ridiculous. For the record, just get something that works. The only person dwelling on anything is you. Your right these thread has devolved we have said our peace. Maybe RG would have the good graces to lock this thread.

Not random we did 3 runs after installing the intake, all produced a gain in that same 6750 range yes 10hp was the best result but the others were high as well 7 and 9 as I recall.
