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

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

Here is a picture to give you some size reference. This is Richard holding the supercharger.

Here's my ugly mug holding it.

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.

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

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

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.

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

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

Cheers,
Hymee.

BTW - thanks for the linky. Reading now.

The interesting thing is, RAP has a CVT transmission in his big ***** 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.

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.

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

no ****, i thought we were on double secret probation about the issue. wow.

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

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?

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.
