Supercharger 101

[ROZ]

For any newbies out there like me, who are struggling with the TLAs (three letter acronyms) and other mystic terms, I found a site that explained a few things really simply and set me on the path to enlightenment. :driving:

Some of you guys over in the States will probably have seen this already.

There's a slight bias to centrif blowers, but what the hey!

When you are ready for some real heavy reading on the subject you should get Corky Bell's Book on Supercharging. It is available through Amazon or major on-line book retailers.

If you did not see the paper on E-Cool, I have attached it.

Cheers

It is a good book. So is his book on turbo's.

I don't remember Corky mentioning things like the throttle response difference between coldside and hotside, or cooling with gasoline.

He really likes twin screw compressors - but the TVS900 "roots" looks to have better efficiency and eliminates that pesky compression ratio that creates heat off boost.

:nono: Must we use the "t" word......

As per the other posts on E-Cool, I got out my Applied Thermodynamics for Technical Engineers, Eastop and McConkey yesterday, and there's all the theory (and a little practical) regarding the infernal :devil: combusion engine and supercharging (plus the T word). Those little grey cells had some real stirring :ack2:, but it's coming back.

But I might look up Mr Bell too. Cheers

I have to say turbo every now and then. My ideal set up is:

1. A variable vane turbine geared down to take what normally drives a turbo, and apply it to the crank. Vary the vanes to maximize power out of the engine (close the vanes until the back pressure starts to reduce WHP), no need for a waste gate - that power goes to the crank. Put all that wasted supercharged exhaust to work!

2. 3" exhaust with only as much muffler as needed after the turbine for noise, maybe just a CAT.

3. A centrifugal supercharger on the cold side, driven from the crank through a CVT (continually variable transmission). A 4:1 CVT range allows full boost at 1800 RPM (2X step up), to 1/4 boost at redline (2X step down valet mode). Adjust the boost based on throttle position, air temp, water temp, and altitude (no turbo lag!).

The add a valet switch on the dash marked Normal and OMG!

Not really a turbo - it gets rid of problems the supercharger and turbo have.

Enough of the "T" word....
