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.

$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

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.

Thanks for repeating what I said and sounding more intelligent while repeating it

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...

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..
