New supercharger
 

Did you see the price on that?!? You could get two SFR kits for that much. Or an M3.

I don't get it...it says the maximum HP is 725, but then at the bottom it says 60-85% more power. Which is it?

And if it is only 60-85%, nobody is going to pay $12k for that!

only thing i can think of is that the stage-1 kit (60-85%) will be cheaper, and it only runs at 7psi. the other kits listed in the chart are possibly different kits, as they are listed at 24psi.

I think the S/C is good for that amount of max hp, but on the renesis rotary, you'll never see that in its current form. You'll have to heavily mod the engine, which will be another $3-6k. Bottom line, that kit is not really an option to 98.2% of RX-8 owners.

Ya'll know that's in Australian dollars right?

Must be in australian horsepower too! :rollingla

it is australian dollars.

This has been discussed guys...

whats this power mod ECU stuff? anyone know anything about it?

Just to let you guys know that is AUD currency so it would be much less for you U.S guys.

But it has already been discussed

What is the exchange rate between AUD and US currency? It has probably been discussed, but I'm tired and don't feel like searching.

$11,900 Australian = $8,723 US. That's for the STAGE 1 unit !!!

1. The engine would last about 2 runs before it blew up, unless you got some major reinforcements.
2. This is a centrifugal unit. Won't give you the low end grunt that many people want, like the Petit & Hymee units (twin screw & Lysholm units).

Still mighty impressive hp #'s

hmm.. 11,900 AUD is 8729.09 USD.

Wow...sounds like an investemnt. Hats off to any1 that can and will go for it. Mighty pricey in my book though.

I'm not bad mouthing anyone I'm just asking that someone teach me how you get more CFM IN WITHOUT ADDING PRESSURE. I wrote about this many times before. THE ONLY WAY IS WITH HIGHER EFFICIENCY.
Sorry I keep hitting the damn cap lock button.
A turbo is a centrifugal as is this unit. They should have similar eff curves. In fact the turbo might better as it has a number of turbines and compressors to fool around with.

Other then that I can't understand their charts. Maybe one of my OZ freinds can interprate it for me. If those are the same size horses that we have here I wonder how the drivetrain is holding up?

If this is true what the article is saying, I will definately buy it, if I have to upgrade the internals to get that kind of power, without blowing the motor I'd do it.. But we'll see..

Actually, it just says "maximum supercharged HP" is 765/725. It doesn't say that it gets those numbers on the RX8 application.... I believe they are claiming around 270HP

They are referring to max potential for the supercharger itself and not for the amount of power it will give you on the RX-8. In the past people have installed Paxton and Vortec units on RX-7 engines only to not get much power. Everyone thought the blower couldn't blow enough air. The problem was just the opposite. The blowers were too big for the 13B. They were always running where the blower surges. Efficiency drops off huge and you get nothing. The blowers themselves could potentially give huge power numbers on other engines but not too much on a rotary. Some just thought the rotary actually uses that much more air than a piston engine. Not hardly. They were ignoring the compressor map and sizing considerations. There isn't a single centrifugal out there right now that I know of (maybe the Rotrex) that is sized good for a 13B. The Renesis isn't that much different. It does make more power but displacement is the same. If history repeats itself with this engine, that blower isn't going to do a whole lot more than that on a 2 rotor. Install it on a 20B and now you've got a different story.

:rollingla :rollingla :rollingla

Thanks for repeating what I said and sounding more intelligent while repeating it ;) :D

What upgrades ? So far no real upgrades for the Renesis to make the engine more bulletproof. There were rumors that some ceramic apex seals were out, but to date nobody has them on their car.

Sounds pretty similar to what Sunflower Mazda tried (along with Canzoomer) but it died by the wayside long ago.

Hey I'am just saying if they can prove themselves right, I'am interested.. And I'am sure most of you's would be too. What are you's afraid of ... Time will tell, like every other promise we heard... But if this one is true Watch Out...

P.S Maybe it's wishful thinking on my part , Because even though I love my RX8 the 284 rwhp I have, is just not enough with today's cars... I drove my friends Corvette's ZO6 and that damn car would kill the RX8. With all the new sport cars out and coming out the RX8 is left behind by many.

I would prefer to keep my 8 , but I'am getting anxious again for more power, And the ZO6 sure has it. I still prefer the looks of my Rx8 with all the modes I did..
