See, this is exactly what RICE RACING is complaining about. The idiots have now confused you by using incorrect, made-up terminology. I would like to point out that the latest iteration of this ignorance made its way from this forum to rx7club.com, so it does work both ways.

When one compressor feeds into another it is called "staging". The setup is usually described in numbers of stages. For example, one compressor feeding into another is called "2-stage", 7 inline compressors are called "7-stage", and so on. Therefore, if you had an engine with one compressor feeding into another, you would describe your setup as a "2-stage turbocharged engine" and you would describe the method as "2-stage turbocharging", or more generically as "staged turbocharging" or simply "staging".

Garrett TPE331 engine shows the design differences between the high and low compressor stages (painted blue in the cut-away picture). The resulting compression ratio was 8:1.

Where is The Lounge? I haven't seen it in about a year now, so I figured it was deleted.

To be fair however, even academia refers to the above as compound turbocharging of a system (at least in Marine Engineering--but then again, I take what that professor says with a heavy dose of salt for just about everything that comes out of his mouth).

Scroll all the way to the bottom of the main forum.

I have a book called auto math. talks about tractor pulling.. tractor was making over 245lbs of boost. 3 turbo's. 1 turbo feeding boost into the second turbo and the second turbo feeding into the 3rd turbo.. 3rd turbo feeding the 245lbs of boost to the diesel engine. they also show a picture of the engine granading into pieces.... insane to say the least..

It has been called staging for over 100 years now, lol. Maybe your marine professor just liked using redneck terms? I had one who would use redneck terms as a joke.

Live Chat and Video? After that I am just seeing forum stats and random album pictures.

Yes, it's insane, especially considering that Buchi was running 71psig back in 1909.
