i was talking to my uni lecturer a while ago and he mentioned turbo expansion, wondering if anyone has come across it before or know much about it?
the idea behind it is you run a standard turbocharger, cool the pressurised air through an intercooler, then run another turbine after this to de-pressurise the air before it then enters the engine. theoretically you can end up with a cooler and slightly pressurised air charge entering the engine. supposed to be more fuel effiecient and such.
thoughts?

How would you decompress air with a compressor?
I would have gone to the kitchen, collected a brown bag, dropped my dacks, pinched off a loaf in said bag, done up dacks, stickytaped bag, placed bag in envelope, and mailed it right to your face for being such a tool.
It's ok, sometimes when we herp, we also derp.

this is a research paper done by lotus, be warned it is long. They used two turbos and intercoolers to see if they could get greater gains.

that report was only theoretical, their next objective was to build a test rig, and they did that but i cant find the report for free anywhere. others have done tests, didnt work too well but they concluded that it seemed a good idea but they couldnt get it working properly
