Chris, Both supercharging and turbo-supercharging are done on aircraft, and
both are used together on some Diesel engines used for fixed operation. I
once say two Cat Diesel engines ganged together to drive a generator to run
a gold extracting machine. It (they) had both mechanical superchargers and
turbos. Also in aviation there is a little trick you may want to experiment
with called “turbo compounding” where power recovery turbines are exhaust
driven and geared back into the crankshaft to increase power to the
propeller. The best solution for your heavily modified XJ-S would be a trick
used in a high altitude four engined bomber. In it a fifth engine was
installed in the fuselage which ran a compressor to supercharge the four
engines on the wings. You could mount a small engine such as the Suzuki 3
cylinder in the trunk and use it to power a screw compressor. A second plus
would be to use the APU (auxiliary power unit) to run all of your
accessories. Imagine how neat the engine compartment would be with no
alternator, power steering pump, air conditioning compressor etc. In
addition, the added weight of the secondary engine would add traction which
would be necessary when this massive increase in power attempted to spin
your rear tires into smoke and molten rubber. Watch out, Bradley Smith, here
comes the next supercar.
