Back to 4.
Richard, what does an axial blower sound like on full song? The reason I ask is that I was just listening to the audio of Jon's turbo on his video post. The whistle was a little weird. To the untrained ear of a rotary newbie like me it sounded weird anyway, I've not spent anytime around RX-7 turbos. Sounded far different to a piston engine turbo.
Don't suppose you have any audio you can post?
You may have answered this question before, but I missed it in the 1050 odd post history!

Don't have any audio. Right now it's hard to predict what it will sound like since we have gears in the new one. The first and second designs were to noisy. We don't want to hear the gears over the blower now do we. There is another generation in the test unit now and we shall see. Also the test cell isn't the engine compartment and sound has funny ways of combining with other harmonics to sound different in different enviorments.
This month has slipped by unnoticed so I guess it will be next month when we start in car trial fitting. I really thought we would get it this month. but alas.

Richard, I know you've said that an intercooler will be unnecessary, but let's say you bring your car to the track with this unit installed. Will you have to wait a while between runs in order to let everything cool down? It was terrible with my brother's MKIV Gti pre intercooler, just wondering what differences may be expected. Thanks.

Hey Richard, you wouldn't happen to have any pictures of other applications you have made the afsc for? Like the porsche or vette? (I think you mentioned them but I could be mistaken)

Zoom 44, What did I build that blower for? Looks like a Chevy lower pulley and bracket and idler. But it only has 8 stages, was it a 90 degree V6?
I only remember making one of those and I though it was 7 stages.
If it's the one I remember it went to Katec in MI. for a bowtie six going into a Toyota. For a man in Texas.
Chevy was in on those tests also.

sorry i cheated and did a google search for Latham Superchargers. that pic has a caption that reads:
and can be found on this page http://www.almar.easynet.be/home.htm about 2/3 of the way down.
An American in Brussels ... The only Latham -axial flow supercharger- in Europe is the pride and joy of my superchargers collection.

i realize you cant say who but how about a hint?
and i meant it earlier- if you need a car figure out a way to get mine from portland to you and its yours for the testing- ill square it with the wife later
and Magix - dont go talking about wawa man - youre making me hungry and the closest wawa is 3000+ miles from here

aoshi, to answer your q about heat and intercoolers. I believe that without knowing but betting is that your brothers car has a turbo. That is wwhy everything in the car is hot after a run. If you don't make much heat you don't need to spend time getting rid of it.
When a yturbo is running hard evrything is red hot. That heat has to go someplace. It's going into the water and out the radiator into the air. When you come in after a run it needs more time to get out because it is not moving.
The added radiator helps this condition,

That SC shown is much bigger then the one I'm developing now.
They had a 5.950 rotor dia the new one has 4.4. The stages were 1.0 inch wide the new one is .700 inches. The old one weighed 26 lbs the new one 11.5 lbs.
The old one had intake in the front and radial discharge in rear. New one has axial rear inlet and radial front discharge. But this can be designed reverse. The big one had investment cast rotors and stators. the new one is cut from solid bar stock.
The new one has an internal planetary gearset. The old one had all the overdrive in the belt drive. Old one redlined at 33,000 new one 45,000.

You don't have a car for testing? All of these people in SoCal and nobody has stepped up to offer a tester? Or have I just read things wrong? Do you have a tester with the mystery company? I'd do it if there would be some sort of coverage in case something goes wrong etc.
