Yep ..a centrifugal, crank powered, blower integrated into the intake manifold..

The V8 sketch looks sort of familiar.. -)

Umm...that internal structure dosen't look like anything I've seen before. But I'm no expert...

That is unreal. What. Zr1 or z06

Sort of looked like one of the earlier CAD renderings I saw on the Forum some time ago.. Same render as here...

wild a vertical center superchager one piston at a time according to the odc ?

The patent shows a Centrifugal Compressor ... not a Positive Displacement Blower ... interesting to see if it ever comes to be as the drive system would be somewhat complex to get the rpm ratios needed.

Nice! That patent application was just released today. Either you have extremely good timing or you are in some way connected to this idea. Incidently,

When that (the one with the red cover) was first shown here by Keeks before the Stingray reveal in January, I questioned whether it was a supercharger at all because it did not appear tall enough. The answer was that the intercooler was remote. Looks like it was more than that, huh?

Excellent thread :thumbsup:

since centrifugal wheels aren't positive displacement, this actually makes a lot of sense. lift increases with increases in wheel tip speeds, which would make this very streetable, and provide ample boost as rpms go up. controlling boost would be pretty simple with a waste gate arrangement. the single wheel would be very reliable at high rpms, as these types of wheels have been around for a long time in industry, and some are known to run as high as 40000 rpm reliably. the biggest issue is keeping junk out of the wheel.

flange

if they realy want to get fancy, they could control it's speed electrically and get away with the clumsy interface to the crank....

texel

Just a nice find.. ties together... Same inventors !! A composite rotor might not stand the thermals in a turbo blower but might be OK for a crank driven system. BTW ..I liked your idea for gamma-TiAl valves ...

In the text of the documents there is wording of a possible electric motor drive. Audi has been experimenting with a eclectically driven supercharger concept too.

This is WILD.

Aren't centrifugal superchargers more efficient than positive displacement? This may help heat issues associated with heavy track use.

Man, i love the innovation.

with ecm technology in small motors being widely used these days, its getting inexpensive to vary motor speeds and quite reliable. adapting to something like this, I would think the hardest part is getting the control loops figured out for the type of reliability needed in a car.

wait! upon further review, the text says "may be" crank driven. I say poppycock. item 50 is a small drive motor for the centrifugal wheel, and items 34 are bearings. they could be magnetic bearings, electrically powered to position the shaft with the top one also being a thrust bearing.......

Wow! This is fantastic!!!

So, why did GM design, and then take out a patent for, an intake/supercharger...for a HEMI? Maybe this is just the design work they did for Chrysler's new blown HEMI, eh?

Stingray23

Could this be for the new CTS-V?

Given how much space is available up near the C7's radiator, I wouldn't be surprised at all if the intercooler itself was up there, somewhere. Right in line with the air being rammed up through the hood vent. The downside with that arrangement is that it shifts even more mass up front, and in this case: forward of the front tires.

Very interesting!
