I'd be first in line for both, now that we've been assured that our off-supercharger mileage won't suffer, much!! :D Isn't that hood scoop right out of "War of the Worlds"?!!

Anyone in the Jersey area know of someone who could pull this off?

Supercharger output targets
Hi All,
I'm sorry for asking that stupid question - I'm sure it was discussed before but I just can't find it in 100+ pages...
What is the power and torque targets of this axial flow supercharger kit?
What is the target price?
Thank you
Ted

Ok, just to back up the dyno runs I bought a new G tech and made some runs with it. I didn't have the room for a q-mile but did some 0-60 runs. the best I got was 7.37 sec. What is the standard number for others? I'm sure this is slow, I could improve it a bit with driving style once i get used tio the car. BTW I had to shift way low to get this number. I can't say exactly where I shifted but just from instinct it was low, maybe 8000 or less. When the car stops pulling I can't make myself keep going I just shift. It's built in after a lot of years of racing. In fact when racing except maybe for top gear you don't use the tach.
I don't know how the G tech compares to magazine times so I'd rather know what other 8 owners get with their G tech. I think magazine times are about 1 second less then what I got.
It was slower with the traction control on. Is that normal?

I'd like all of them to be high.

My car doesn't "stop pulling" until it hit the limiter. The may power right to redline. In fact, unless I am a total tosser, my instinct is they feel so good up top like they just keep wanting to go, and you hit the limiter when you feel like it could keep going. I guess it is a rotary thing ![Wink](https://www.rx8club.com/images/smilies/wink.gif)
I reckon there is a problem. They should do 0-60MPH in the low-mid 6's.
Cheers,
Hymee.

And with your exhaust it should be a sec quicker still, right?
![Wink](https://www.rx8club.com/images/smilies/wink.gif)
Really though the thing just doesn't want to pull to redline. That brings up another point, you'd think the dealer would notice that. If they drive them every day they should know where the power is. That brings again the point, how many owners are out there with less power then even what they are shipped with. How do they know? I can assume there are no owners on this forum who would not notice the power falling off before redline. At least they haven't said anything.........wait a minuite....there is a thread on that. Loosing power at 7000 or something like that. It's under problems section, I think. Hmmmmmmmm

Gtech Pro RR gave us some quite nice numbers in 0-60 time....
Many many runs and some 8s with catalytic converter+pipe+catbacks hit some good 6.1-4...I have some sheets if someone wants to see...The 8s who made that times had both trust titanium catbacks,n flash,both ms flywheel,the one ms disks and one rmagic catalytic system and the other supercat if i remember correctly..
They both made same numbers in a couple of runs..
Hay rp what mods on the 8 you run with???It seems low..Have you calibrate your gtech right???

Hey i am going to forget the na soon and i really like to know when this sc will hit the market....????
And can we get more than 60whp and good torque gain in the low with that kit??Just estimate rp!!
Sorry i only read 50 or so pages...Don't flame me!! :D

Bummed, but bring on OU!
From what I understand, boost comes on linearly with this supercharger. So the overall feel of the car (linear power climb) should remain relatively unchanged. There'll just be progressively more power throughout the rev range. While some torque down low would be very nice, the size, weight, apparent ease of installation, and efficiency of this unit are what attract me to it. You could probably say that the boost curve would be somewhere between a positive displacement unit and a centrifugal one. The first being a flat boost curve and the second being exponential. So you get an easily usable power band and a decent gain up top. And with the atomized fuel delivery through the blades, efficiency can be very high.
For a smaller thread and a good explanation of what's going on inside the sc'r. Visit s2ki.com and search for axial flow.

Almost a week without a post from Richard. Getting AFS thread withdrawl syndrome... ![Frown](https://www.rx8club.com/images/smilies/frown.gif)
Richard, are you:
A) Having a blast thrashing your 8 around (assuming your hi RPM power issue is sorted out)
B) So dissatified in the 8's power that you're spending night and day getting the AFS hooked up.
C) In jail, for performing grevious bodily harm to a Mazda service representative you told you "All RX-8 do that. It's perfectly normal"?
D) Given up and moved to Australia, destined to spend the rest of your days drinking beer and watching 8's whiz by with Hymee Enhanced stickers on them.
Let's get this thread back up on the top of the page where it belong with an nice update from Richard.

Good group of answers. :D
A) As you say, no hi end power makes a little less fun.
![Frown](https://www.rx8club.com/images/smilies/frown.gif)
B) I'm unhappy but still can't put a SC on it until the base is correct.
![Mad](https://www.rx8club.com/images/smilies/mad.gif)
C) I've learned restraint in my old age. But just bearly.
![Roll Eyes (Sarcastic)](https://www.rx8club.com/images/smilies/rolleyes.gif)
D) Now this makes the most sense, I think I could learn to like that rum Hymee is so fond of. The beaches, The bitches, lots of fun drinking mates what else could I really want. :D
![Cool](https://www.rx8club.com/images/smilies/cool.gif)
![EEK!](https://www.rx8club.com/images/smilies/eek.gif)
I just don't think I could keep up with their alcohol intake.
And they have tons of shellfish to excite my gout.
![EEK!](https://www.rx8club.com/images/smilies/eek.gif)
I could lay around on the beach in major pain the rest of my life.
I couldn't walk or move any major joints. I'd be the life of the party.

Just for everyone else who asks the question: how much compression.
This is the factory graph, it takes into account leakdown by knowing cranking speed. There are other things to know, like it takes a special tool to get the comp for each seal. Use it if you can.

Richard,
The other day I found a book at my parents house written by Pat Ganahl about supercharging (I must have bought this about 15 - 20 years ago, but didn't remember). Anyway (to my surprise) it mentioned you with the axial flow supercharger and that you were involved with Formula 1. Is this true or did that guy mix something up?

I think that at that point in time Pat didn't know the difference between open wheel formula cars. I actually ran F/Atlantic here and the Canadian series as far as Newfoundland. I drove other road race cars on a one off ride basis though.
Also I raced drag cars, boats (Drag and Endurance) and Bonniville. On top of that I built almost all of them and the engines. Exceptions for the one off rides that is.
Today I doubt a person could do all that as things are so specialzed with chassis and engines it takes a development team for each to be competetive. Even the Atlantic circut these days takes a crew of 20 and a full back up car. There was no way that kind of money was available in the '70's.
Gilles Vellenuve was the best funded driver when I ran and he shared a back up car and a crew of maybe 5. No semi just an open trailer stacked with two cars.
They've come a long way. For the best, I don't know. Hard for a little guy to get started now. For sure no one who runs his own shop and builds things. I helped fund my racing by making parts for others. I even made my own wheels, bodies, wishbones, halfshafts, radiators, dry sumps and more.
I even built my own tub twice. I used March bulkheads and modified their design.
So if Pat was confused it is understandable, he had seen all the stuff in the shop.
#1992
Well, I thought you could have been involved in Formula 1 as a supplier of parts, but I doubted it, since F1 was always more a British/European than an American thing.
Considering the fact that you were racing on your own budget is actually more impressive.
In addition, you survived. Gilles Villeneuve and many others didn't make it, as car racing back then wasn't obviously as safe as it is now.
Bonneville is that land speed record thing, right? What speed records did you aim at?

Until the engine issues Richard's car has get fixed, we won't see much. The blower is waiting to go on the car for mockup and testing. The engine isn't being very cooperative and Mazda isn't being terribly quick to find the answer.
#1996
That's right, what RG said. I can't use this car for development until it is right. Mazda knows who I am and what I intend to do. Therefore if they wait long enough I'll void my warrenty all by myself. So this car is usless to me right now.
If I SC this car and have less then the best results due to it's organic problems how can I advertise it?
Since the compression is down below spec it does not lend itself to supercharging. If there is seal leakage now what happens when I increase the pressure?
The whole ball is in Mazdas hands now. I have made progress though but it will never get up to where it should be. I have it reving now but not real willingly.
Even giving it all the credit I can the power curve is still wrong, it doesn't look like everyone elses.
I have a dyno from a forum member who used this same dyno and it makes more power and the curve looks right. So it's not the dyno. I've run it twice and have seen better numbers but it still is down and doesn't curve right. And it's intermitant.
Fred, I'd like to find a way to get this curve to you. My scanner doesn't work, do you have a fax?

Does it feel like it goes lame at the point in the rpms? Is there supposed to be a bit of a bite when the ports open up? When I'm to the floor going up the rpm band myself I don't notice any pull in performance at any specific point with my car and I can see the speed rising but it doesn't go up at any noticeable burst either, is there supposed to be one? This has got me curious to the point of where I wonder if I have this issue as well.
