I watched them, and they don't prove a thing.

But have fun wasting your money.

This thread is cracking me up. "Compressor" implies that it compresses the air. Which is not possible with an electric CPU fan sitting in the intake track. This "kit" and others like it are a scam designed to fool illiterate retards into buying $10 of junk for $200 and bolting it to their car. If you waste your money on this garbage you deserve what you get (which is nothing). I am amazed that companies making this junk are still allowed to legally operate, and depressed that morons keep making them money.

I think RX8Club should have some kind of IQ test like Idiocracy where you need to put square pegs in the square holes to log in. Site traffic would probably plummet.

why be so negative, what if this kit actually were to work. Yea it is nothing like a real turbo or S/C and will never compare to them, but what if there were actually a power gain off the line. Brushless electric motors are Very powerful with the right power supplying them and can spin up to a ridiculously high rpm. I mean no one will ever know unless someone try's it, now whether it"ll be on an 8 or not is a different story.

Because there is no "what if", you are just not comprehending.

Then please, let us know how it goes once you've tried it...

I gather that you didn't read through the math of why it doesn't work?



How about this:
What if diesel would work in our engine!? I mean, it should mean better low end torque, right?

Jcola

it'll depend on the price, yea I agree with everyone that i am not gonna pay no 1-2k for this thing. If everyone is saying not to do it to the 8 then I wont, if anything I could try it on a pos car yet again depending on the price of the kit.

This kit doesn't look like a fan placed in the intake path. It actually looks like a Turbo, but not hooked up to the exhaust, hence no exhaust manifold. It has an electric motor that powers the turbine.

I am not saying that makes it worthwhile, I still don't trust it at all. As RIWWP stated, the amount of batteries required to power this thing up to 5psi would make the car immovable from weight!

Jcola

Exactly gravey, the compressor has the right type of fins to compress air. It's not just some fan with regular fan blades. As for the amount of power it would take to power it, that is where the brushless motor controller comes in. Without the controller it wouldn't work at all, and the batteries could handle the draw.

Quote from the webiste "These batteries are extremely robust and can capable of short periods of high discharge current"

they are SLA batteries meaning sealed lead acid

^I still doubt it has the power to produce 5 psi.

And I don't trust quotes from the website that sells them. I'd want data from application, and not just "It feels Faster!" I'd want to see before and after Dyno numbers, and a boost guage to show the actual boost.

And then on top of all that, if it did what it claimed. Powered by Unicorn Horn batteries no doubt, It would HAVE to be tuned for the boost. No question.

now that I agree with, I would want to see an actual boost gauge as well, but dyno results and numbers say that its pushing about 4psi

Gravey, I gather you don't trust their Arduino LED display that shows a random unidentified number?

In Clarkson voice: "Hey look! It's a number! And it's going up!"

Edit, in the video it actually goes down when on the throttle...

Who's dyno numbers? Theirs? Or BRZ/FRS Forum members?

Maybe that's negative boost it's recovering from!

I want one of these . My turbo setup was such a pain to get sorted . Took me years and lots of $ to get the setup right and learn how to tune it properly .

I think i'll tear it all out and fit one of these bad boys !!!!!!

RIWWP

I took a look at the thread where the one video with a dyno chart discusses it. 3rd party testing, and I admit that it does appear to have some sort of very brief and short duration boost, with a hell of a lot of caviates.

Someone else also dug up the true dyno chart, where he already had nearly all those gains from prior mods and an aftermarket tuning solution, so the dyno chart shown in the FR-S video is rather deliberately misleading. And all of those other mods to be able to result in that power increase was more than the cost of the entry level 300whp FR-s turbo kit.


Soo.... yeah.

Jcola

the number is the voltage of the system, the kit runs off 24v so with the added voltage of the alternator it comes out to be 27.8 volts I think. So when you activate the system at WOT the number starts to go down as it's drawing the power down. Once you let off the throttle the system recharges back to 27.8 volts and from what i have read that it actually fully recharges by the time you slow down from the run.

so now that everybody has looked into this a little more, would it be a go or no go or is it still just to early in this kits development to take the risk?

Jcola;

See my PM, you need to get an A/T AP. You can not load maps from an M/T onto an A/T car

RIWWP

iTrader: (2)

no go, all around.

A) We think it doesn't work

B) if it does work you are running a huge risk of destroying your engine without tuning

c) Tuning for an intermittantly present factor is going to be next to impossible


Piston engines can get away with it, not a fragile rotary.

Before you throw out "5psi is safe!" again, NO pressure is safe on a rotary with a bad tune. Hell, VACUUM isn't safe on a rotary with a bad tune.

Gravey

iTrader: (3)

Which is exactly what this thing says it is doing... Applying a couple seconds of boost, which discharges the batteries, and then going back to normal engine compression range.

Wow, how would you even begin to tune for that?

Brettus

iTrader: (2)

That part is very easy in a maf based system . More airflow = more load = more fuel.

Our stock maps are capped to NA loads however . So any amount of boost would see the car run lean .
Maybe 1 psi would be ok without a tune but that's about it. .
