Mr. Alastor187, I have a feeling this is going to be a great thread. I sent a eMail to Ben at STS and invited them to join us in this discussion and shed some light on remote turbo mounting.
At this point please bear with me as I don't have my Thesis right in front of me but have asked my sister to fax it to me, like right now. But I will tell you what I know off the top of my head.
I know for a fact the 2 identical compressors, one driven with a DC electric motor an the other by exhaust turbin the discharge air on the DC driven compressor was cooler than the exhaust driven turbine leading us to believe that the exhaust turbine transfered heat to the compressor.
The compressors were driven to 10# psi and the only difference being scorce of drive.
Another test was with compressed dry air and another with air with 20% water mist. In both tests 150lbs of compressed air was used and the one with moist air had much more power.
The exhaist in a 4 cycle engine has particals in it and these particals striking the turbine help increase the power of the turbine. This is the reason a turbo'd engine running a fat (rich) mixture develops more power. Under load is when a turbo is at it best. More particals in the exhaust.
Because most people see a turbo run harder with higher heat they think heat is what is making the power when in fact the heat is expanding air very quick and raising the pressure causing the particals to strike the turbin blades at a hi-velocity which in turn drives the turbine.
Believe it or not the interior bullistics for a gun work much the same to driving a turbo. Once the gun is fired the powder starts burning and expanding rapidly and building pressure. Depending on the powder and its burning rate determines when it no longer builds any more pressure. It was found a shotgun with a 14" barrel was perfect. Anything longer and the power of the load deminished.
Where as gasoline has a much slower burning rate and builds pressure for a longer period than gun powder.
