Just for the record, I'm thinking RP will hit between 320 HP to 350 HP (SAE) on a production model for the average RX-8 M/T. Just enough, not to hurt anything, but plenty fast.
What do you guys think?

no change of injectors... my guess is ~ 250 whp...
if you are looking for 300 + this is not for you... the answers are in the thread, and yes i know it is huge...

250 WHP is nothing to sneeze at. A little bit more, like 275 WHP would be even sweeter. That would translate into a nice HP (SAE) rating too, somewhere slightly above the 300 HP range. I'm of course hoping for 320 to 350 HP (SAE).
I want to see a little more than 275 WHP for the RX-8 M/T, because that would mean the kit would bring RX-8 autos into higher performance levels than people expect and they have further to go to get there. I don't see why something like an Axial Flow Supercharger can't do it. But, of course, we have to wait for the kit.
With the kit being easy to install, decent price, etc... it would make itself a must-have.

I would be as happy as a puppy with 2 peters for 250WHP.
I am wondering how well the AccessPort will be with the AFSC. Will a seperate boost controller be needed?

The customer gets to choose two of them. I guess development time can be thrown into the mix as well.

Ok, I'll break the silence. At this time though we are not ready to call final numbers for customer units my best guess is plus 85-90 at the wheels.
Now I think there is going to be some help from better exhaust meaning hign flow cat or midpipe. That is nothing different for the 8 then anything else. You want to make 50% more power don't you think you need to get that much more exhaust out?
I have had some inquires from people asking about pulleys, I have yet to be convinced that they add anything you can measure. Then of course it slows down the supercharger when you get one. It's a no-brainer.
If you must do something right now get the exhaust mods forget the pulleys.
Resist getting any computer componants as that is being solved as we speak.
If you already bought a controller we will try and help with reprograming but there is no promise of ready made maps for final tuning.
Air intakes will not work with this unit as we use some of the room for other things. The kit comes with it's own intake. Same goes for the strut bar, it's in the kit, others will not fit.

I have been putting off mods to my car to wait for the SC. I am about to start on the suspension (just tripped 32k. It's beyond time.) and have been trying to figure out the exhaust for about 6 months. Other things are tempting, but I geuss I will hold off and wait.
If I am a REALY, REALY, REALY, REALY good boy will Santa bring me one for Christmas?

oh jesus, damn richard, now you've gotten me really excited, I kind of wish that you had kept quiet so I can at least wait in peace. Now I'm going to have trouble falling asleep for the next month.
Can you make smaller S/C pullies so those of us with pullies can get the same performance as those without? I still think that -full alt and - full a/c drive would do the S/C good.
Now to the store to buy a few dozen Kleenex boxes...

RP has spoken. Don't do pulley or intake. Get new exhaust. 85 to 90 more to WHP. Oh yeah baby! Must have kit!
Hey (before I get too happy), will there be a kit for RX-8 Autos? Hoping Santa hooks me up for Christmas.
Also, might be silly question, will this kit have a switch so we can turn the SC on and off. My concern is gas mileage and being able to get boost when I want performance and to go easy, to save gas.

Many, many pages ago it was stated that 4port support would not happen. Whether that has changed...? Doesn't really matter to me anymore. There will be other options.

wow that sounds nice. its cool to know what stuff we shouldnt buy: pullies, intake or strut bar. and i was just looking to buy pullies or a new strut.
is it funny so short after RP says this that there is already a couple people asking about it for the a/t, including me

That would be sad if RP will not support 4 port Auto's (as there are a number of them out there). Can anybody confirm if the 4 port Autos will or will not be supported?

I'm pretty sure I read earlier in this thread that RP was not planning a 4 port kit.
My post earlier asking if he was working on an AT kit was a lighthearted joke.

We can make smaller pulleys but that would lose the belt wrap that we want. Bigger accessory pulleys are ok just don't make the crank pulley smaller.
Interesting thing about the auto is that we have had a few requests for them and I think there is someone out there who is looking into a manifold for four ports.
The kit will work for the auto if you make a manifold. We can't do it because we will never get our money out of it. Somewhere out there someone knows a fabricator who will make a couple of one off parts.
Zoom44 is right, with this setup off boost is when you do not have the throttle open. When the throttle is closed nothing is getting in so it does not have anything to compress. Therefore it does no work, the rotor is spining in a partial vacuum and uses almost nothing to turn it. There is one part turning in a vacuum on precision bearings, nothing else to use power. Oh yea, I forgot this design has a small planetary gearset built in. Very little power is used there when no load is on them.
Give you an idea of the size picture a three speed bicycle hub. Maybe a little bigger and wider and for sure a lot more precision. But that gives you an idea of how little power the SC draws.

The max HP numbers arent really important... 80-90 more whp is enough, wat the supercharger gives is a lot more low end than the greddy unit, and borrowing the dyno from hymee supercharger, we'd still get the stock power/torque curve, which is excellent!

Somebody has to do something for the Autos. Anybody working on the 4 port manifold want to step forward?
Autos are a huge market percentage of the RX-8 market. The Auto guys are the ones who will be craving power the most. M/T 6 speed guys are already walking around with 230 HP to 250 HP ( I know, but that was what Mazda said, and you might get it back by flashing the ECU). The RX-8 Auto guys are the ones walking around between 190 HP to 215 HP (depending on country and model... mine is supposed to be 210 HP), so the superchargers will be the thing for this group.
