Customer Report on the Rotary Extreme Intake
#101
Little off topic. But...
I do not currently own any Rotary Extreme product. However, I did have the opportunity to deal with Chuck. All I can say is that not only is Chuck's customer service top notch and he is willing to stand behind his product, he is also very willing to share his knowledge.

Nice offer about supporting the dyno testing, Chuck. The more tests conducted and shared, the more confidence can be built.
I hope you don't mind, but I'd like to discuss Poman's results that you posted - a general discussion, not just with you, but I'd invite all to comment on them. Here's my thoughts:
On the first set, Run 2 stock, Run 4 no filter, there's a bobble in the power and torque curves of Run 2 around 8K rpm that looks like an ECU pulling fuel/timing - like we've been told the safe/limp mode does - but still, if we accept that as a valid stock run, 185.7 hp and 139.2 lb-ft torque. Removing the filter makes 6.6 hp more for 192.3 - Again, I'm sceptical about Run 2, since the torque and hp curves vs. Run 4 are overlain perfectly until the bobble at 7.5K.
Second set of curves, with the RE intake, the very best run gave 193.3, or 7.6 hp increase at peak, but 3 lb-ft less torque than stock. In other words, it lost power over stock until revs were beyond 8K rpm. The other two RE intake runs make about the same peak power as stock (less power anywhere below 8K rpm, and less peak torque).
Third set of curves, run 15 stock airbox with aftermarket exhaust Poman built himself (I am assuming that the aftermarket exhaust used is the one Poman documented having built in earlier threads) pretty much equal power to stock run - up 2.8 hp, down 2.3 lb-ft torque. For Run 17, add in the RE Intake to the aftermarket exhaust, and he's lost 1.1 hp peak and 0.7 lb-ft torque!!
So, Poman Ferrari has this intake and an aftermarket exhaust on his RX-8, and it makes exactly the same power it did stock. If his "stock" dyno run (Run2) was more representative (ie without the safe mode bobble at 7.5K), then he's probably actually lost power from these mods! Am I misinterpreting these results somehow?
The runs also point out the inaccuracy of the butt-dyno impressions that everyone mentions when they install mods, since Poman himself claimed in
this thread "Mid range and top end are vastly better. I will do back to back dyno work early next week to confirm what the butt dyno is telling me." Yet, the dyno tests confirm the opposite - that mid-range was no stronger on any of the runs, and only at very peak revs was there a maximum of 7.6 hp improvement, and a minimum of no power improvement.
Again, to be clear - I'm strictly looking at the data from the dyno runs by Poman and discussing those results, no insinuations or accusations being made. I appreciate Poman making this data available for the community's benefit.

Gordon

Ram air intake is still at the development stage. There are a few issues that need to be addressed. I can't reveal too much but I can tell you that the stock intake system is not a ram air one as thought by some people.

Chuck, I applaud your efforts. The dynos are looking good at first glance.
Just caught Gordon's comments and will try to take a closer look at the dynos soon....

1. The bobble is there on every runs. The bobble is caused by ECU running in closed loop trying to keep the target a/f oreset by the ECU. The same kind of oscillation you on a/f meter when you are cruising. You smooth out that bobble by using the dynoview's smoothing function. Maybe PoMan set the smoothing at 0.
2. What's skeptical about run 2? I don't get your question. For this one, you can do it yourself without buying any kind of aftermarket intake as I have mentioned many times already. If you are skeptical, you can put your car on the dyno to see if you see the same result.
3. Maybe you have a super keen eye. I don't know how you can see the mods only makes more power than stock above 8000 rpm with graphs from different pages. I will wait until PoMan Ferrari to provide the comparision dynos on the same sheet or some raw data. The only thing I got are those bmp sheets.
4. How did you conclude that with RE intake and cat-back exhaust, the car lost HP? It made 194.6 HP. Maybe you read it wrong?
5. If you know how to read dyno sheet, you will see from my own dyno sheet, the intake makes noticeable power above 6000 rpm. Super mid-range gain was never mentioned and the intake was never advertised in such way. Anything from 6000-9000 rpm are usable HP.
6. The dyno sheets were posted just to show there are definitely ways to improve the intake system and the intake does make more power than stock. If you want to argue about how much HP gain is there, maybe you should gather 1000 dynosheets from different rx8's and average them out to get the most accurate result. I don't have the finance to do that. I am already doing the best I can. My $50-60 profit per intake is not enough finance the dyno project to the very pin point. I might as well stop selling it and forget about the whole thing.
Since you are very interested in dyno results, can you contribute and share? I really don't understand why you don't put your car on the dyno and do the tests yourself?

We are talking about the Short Arm Intake here. It's already out and there is no secret. You don't even need to buy one. YOu can see the design on the net because I have installation instruction posted, step by step. If you have the means of manufacturing, you can copy my design without buying one!
RAM air is a total different design. Tell me one company that's stupid enough to give away their R&D in public when their product is not released yet, especially when that info is the key to success of finishing the product.

In several places in that thread, you state that you know details that you are not willing to share about the intake design. Thus, my conclusion. That's not speculation, it's a fair conclusion based on your pretty clear statements.

This the reason why I want to get 10 dyno sheets from different cars and summarize the result.
Remember every car will have some variation. Even with the same car, you will see different dyno results on different days. Variation within 1% can be expectged. There is also uncertainty. An engineer like Gordon should know something about this. As long as the HP difference is within 1-2 HP, it can be accounted for as error or uncertainty. But 6-8 HP is defintely not coming from uncertainty or error.
From a statistic point of view, more is better but I simply don't make enough on the intake to support 1000 dyno's. I don't even think there is another company that will give money to their customers to do dynos to prove their product. This is a risky thing to do. How about if the customer didn't install the product correctly? How about there is mechanical problem with the car? Many things can go wrong to give inaccurate result but I am willing to step up and offer this. Why? Because our company don't sell BS performance parts. Our dyno sheet is real. There is nothing to hide.
I am doing the best I can and if pepole still want to prove me wrong for the sole reason of proving me wrong, I feel I am just wasting my time and money here.

If you are very keen at the torque number, you forgot a very important concept. It's the HP that makes your car accelerate, not the torque. A mechanical engineer should know about this.
You should also compare area under the curve. As long as the area under the curve of usable hp is more than stock, your car will accelerate faster.
Your car will be faster if your usable HP is more. If you are racing, your usable HP band will be from 6000-9000 rpm. I doubt the people who buy the intake will shift at merely 6000 rpm. So when you need the extra power, you will feel it.
Unless the stock intake is really bad, it's not possible to improve the low end or mid range drastically by simply putting on an aftermarket intake. Higher rpm requires higher air mass/ time and that's when a higher flow intake system makes the difference.

I'd also agree with your conclusion that it's very hard to improve on a good factory intake at low and mid-range rpms - however, with many aftermarket intakes for other cars *cough*honda*cough*, it's very easy to lose power in those ranges. It's reassuring to see independent confirmation that very little or no power is lost in those ranges with your intake.

Gordon

a bit of a side step here...
i installed my RE intake today...chuck heard my concerns about noise before purchase and offered return if i was unsatisfied. a straight shooter it seems to me.
but my question to anyone who has this intake...is anyone experiencing hesitations at around 41 or 4200 rpm while accelerating? i am experiencing this and dont know if it is from more turbulence or a vacume issue or simply an expected side effect.

Omicron,
Did you manage to get to the shop to Dyno your car?
Anyway-
I have a Uk spec car that I have dyno'd in standard form on two different machines.
The first was a 'water' dyno and showed 179 RWHP.
The second was a more modern approach, and the print out is below: Max power on a standard UK 8 = 181.7.
I am in the process of arranging an intake, full exhaust with cat removal and CZ stage 2 hopefuly.
As normal, will post as soon as we know.
Ant.

i also istalled insulation in my RE intake and it toned it down nicely without losing nice sound of the product. did you insulate the whole inside of the box or just under the top?
