this is the best first post i have ever read. dedication, i will bet you have a good work ethic also.

you didnt doze, the engine problem has never been explained. or answered if it was fixed. the used one was for mock up. dont know if i works or not.

Great summary of the position so far....all highlighting the need for an update, and answers to all those....unanswered :wavey:

well you missed the part where some of us have actually held one now:)

Here's my ugly mug holding it.

Photic 11-03-2005 03:43 PM

After holding it and playing with it, watching the little blades spin so effortlessly in person I can't wait to get one. Each day I anxiously wait for the bold little letters to appear and the time stamp to change.

Richard Paul 11-03-2005 03:51 PM

Let there be an update RG.
Due to the tight fit of things in the engine compartment a whole new blower has to be built. This one will have an angled intake in the front and the outlet will be from the rear. While the actual stages stay the same every other part of the unit must change. That is a major undertaking. One I did not really want to do.

Think about it, the front and rear housings are all new, the hubs must change sizes. Then the center shaft is all new. The types of seals swap ends so they need new glands. The gearset has to move foward so they must be redesigned.
Oh, the nose peice can stay the same as can the pulley. Small help.

Then there are new adapters for both ends. Everything chases everything else.
It would be a luxury to buy an off the shelf blower. J/K :banghead: :soapbox: :crying:

Nobody worry Hymee and I are buddies, I just like to rib the rumswiggingbastard :beer:

Are those your PJ's ?

therm8 11-03-2005 07:57 PM

I was thinking during some downtime today...which usually means I come up with some sort of off the wall idea that doesn't work:

Axial flow and centrifugal sc'rs make most of their airflow in the upper rpms. Would it be possible to have some sort of CVT-like transmission between the pulley and blower to control the blower's rpm to provide twin screw like boost performance? Thus gaining the boost profile of a twin screw unit, while retaining all benefits of the axial flow or centrifugal unit. Seems like it would work to me if you could find/design the "transmission."

Just a thought, while waiting for more updates.

Swoope,

I'm impressed - figuring out someones work ethic from just that ... (granted that same work ethic drives my wife nuts sometimes - after 10 years of married life, I think I've got that whole work/home balance thing worked out pretty well . . . er . . . at least until she decides I'm wrong :-)

p.s. thanks for a whole lot the beers sig (J/K), everytime I saw it I got that song stuck in my head . . .

b-double-e-double-r-u-n ... beer run!


/back on topic/

Therm8,

I believe that the question of possibly using a CVT like transmission was asked a ways back ... but it would of added too much cost to keep the the axial kit competitive.

Now if cost were no object . . .

naw not hard to figure, i did the same thing. read the whole tread in an evening. looked up and the sun was coming up. that was before the thread hit the 1000 post mark.

still hope one day to find out what the actual problem was with the yellow car.

beers

I was just wondering anyway. I have seen 50cc pocket bikes that run CVTs, and the bikes cost $400-800. Obviously those would be too big, but given the cost of the bikes, I wonder how much scaling down the CVT would cost. Now mass production = lower cost, but there'd be a large market for supercharger sized CVTs I would think.

And this guy seems to have come up with an idea to eliminate most of the inefficiency associated with CVTs: http://www.andersoncvt.com/howitworks.html

Hymee 11-03-2005 10:17 PM

50cc - Too big??? :eek: A blower takes a fair amount of power, no matter what the type.

Cheers,
Hymee.

BTW - thanks for the linky. Reading now.

Hymee 11-03-2005 10:21 PM

The interesting thing is, RAP has a CVT transmission in his big mutha test stand he uses to spin the blower and do his measurements. I've seen it, and the blower, in action. Refer to some pics of mine from ages ago. That was the day torque disappeared. Thankfully, my twin screw project has found an abundance of torque :p

Cheers,
Hymee.

Richard Paul 11-03-2005 10:28 PM

About 1989 I was looking at a proposed CVT from ZF of Germany. It was about the right size. At that time it was mechanicly controled. Today it could be electronic and be wired right into the ECU. ZF never went foward with it to my knowlage.

I only have this one life to give to supercharging and it's winding down soon. A big company that wanted to put the resorces into this could make some progress.

As to the car, NO it has never been fixed. :crying:

rotarygod 11-03-2005 10:28 PM

Hymee I hope you found torque. Weren't you the one that lost him in the first place? ;)

Ten more years in the shop and another 20 on the front porch in the rocking chair. 1000's of sunsets left... :)

You'd better hurry up and teach me what you know so I can continue the tradition after you are gone of never having a sellable completed product ready! ;) j/k

Hymee 11-03-2005 10:59 PM

RAP,

Do you have a USB port in the back of you head? Then I could download all that info like I did from your PC when you went looking for Torque.

Yes - Torque did eventually turn up. Sometime after I left for back home here in Aus.

Cheers,
Hymee.

Amazingly found by the dog catcher just around the corner... coincidence? :suspect:

We're still thankful Richard's dogma was not run over by karma. :wink2:

I could die a happy man knowing that Fred would continue development work and be sure to never sell anything. I could just put it in some kind of trust that stipulates all those things. It could be passed down until the world ends.
The ultimate brain trust. :rollingla :hahano: :slap:

I'm secure deleting that from my brain - give me a second. OK, all better now. Now, back on track, you never replied about if your SC will allow the Mazdaspeed Front Strut Tower Brace to be installed...

Richard Paul 11-06-2005 10:52 AM

Poke your minds eye out did ya? :lol:
I don't have one of those strut bars. The only thing I can do is make sure it fits the stock one. Notice the room Hymee has, then go back and look at the photos of mine mounted on the mock up engine. You can see how much lower mine is compared to the alternator. So just about anything should fit.

If it were imposable to make it fit then we would just supply our own bar. Not a hard part to make.

Notice also you can add oil to my setup. Even see the oil filter. How 'bout that Hymee?? :dunno:

Nemesis8 11-06-2005 11:37 AM

Cool, I figured it was OK. Now put an LED on the back side of the blower so I can see that friggin' dipstick at night :)

guitarjunkie28 11-06-2005 12:37 PM

richard... let's pull the 35r off my fd and blow it :D:

Hi Richard,

What does this mean for the project? Does this mean it may not happen at all, or be delayed a year? I have been silently following this thead from the beginning, and now check RX8club mostly to see what it happening with the project.

Thanks and best of luck.

zoom44 11-10-2005 02:26 PM

sweet everyone go back a page and look at the mock up pics- then forget them 'cause hes doing it different now:D:

Richard Paul 11-10-2005 10:24 PM

I still can't see them. Then again I can look at in 3D.

FYI the drawings are in the computer and being detailed. Hope to produce the new parts this month.

It looks like CFH went down for some upgrades. That's cool. Hopefully it won't break again.

Has the engine management system problem been solved?
Keep up the good work to all grumpyoldbastards
Hope it won't be too long as petit has one almost ready to go

rotarygod 11-12-2005 02:21 AM

I keep telling people that I don't look like what people expect. Everyone expects me to be some old guy with a white beard who was around to see the invention of bread. I'm 29. I'll be 30 in March. It's going to be tough for Richard to be in his 30's when he raced at Bonneville in the late 60's!
