Stay with me on this one, There are quite a few cars with remote turbo installations around now which gets over space restrictions in the engine bay, so could a small engine off something like a generator or lawn mower be connected to a supercharger in the boot and piped into the main engine, I can see a couple of advantages 1, no parasitic losses from driving the SC and 2, full boost at all times. I'm I being completely stupid?
EDIT: thinking about this a bit more, if the SC Takes about 30hp to run it at full boost, then I suppose a motorbike engine would be better.

Not crazy, but you may need to find a way to vary the S/C output for the cars main engine, perhaps link the S/C drive engine to the gas pedal. Or even better, linked via the ECU....and while you're at it, get it to drive a fan and get ground effect too! Here

Intresting but wouldn't you be better looking at running the supercharger of a geared electric motor / speed controller linked to the tps?

Stop drinking the petrol!!
I am really liking the idea of remote turbos though

Ok, left wing thought. . . Supercharger = large drive load Turbo = driven by exhaust gasses
How about the cold side of a turbo, modify the hot side to accept a belt dive? Less rotating mass so less losses.

Less rotating mass so less losses. the gearing to get a belt to drive the turbo cold side at 120,000 rpm would be a nightmare to sort out, and rotex have already done that....lol

The best way to go, Nic Mann, of Morris Minor fame, 1700 HP using a helicopter starter turbine to supply constant boost to a big Turbo
|
|
Atmo V8 Power . No slicks , No gas + No bits missing . Doing it in style. Austin A35van, very different------- but still doing it in style, going to be a funmoble

only problem with the bike engine in the boot driving a charger would be getting it to respond and rev up quick enough to avoid lag - unless you kept it at high revs continually and wasted the unwanted pressure through an enormous BOV
Nic Mann's machine is incredible, i think he switches the turbine to high rpm for the whole hill run. Once he gets it in 2nd/3rd gear that thing just disappears!

Yep, if I ever do it, the SC will be at full boost at all time and just dump the excess.

A silly concept I've thought of recently, and very tempted to try after finishing my little jet engine project (in Readers other modification section!)
A diesel not producing smoke, has abundant oxygen still in the exhaust. Feed the exhaust into a combustion chamber, along with a fuel source (LPG,etc) on the outlet of that... have a LARGE turbo. Plumb said turbo into the engine.
Idle would need to be kept at around 2k+ to keep it going I would assume, and would suit being placed far downstream of the engine, for maximum cooling of the exhaust gas

...maybe one day the Chinese will actual prefect a real electric suspercharger ! The new Formula 1 cars essentially do have an electric supercharger, there is an electric motor/generator on the turbo shaft which can spin the turbo up to boost when the exhaust pressure is not sufficient. Conversely, when the turbo reaches the target boost pressure, any excess power from the turbine is converted to electrical energy by the generator, hence eliminating the need for a wastegate and recharging the battery. Eventually this technology probably will trickle down to road cars. The only obstacle on current cars is the low system voltage. Ideally for future cars, it would be much more convenient for the industry to move to a standardised high voltage. I believe the proposed nominal voltage a few years ago was 42 volts, but for whatever reason it hasn't taken off yet. The wiki article is here: en.wikipedia.org/wiki/42-volt_electrical_systemI remembered reading about these things in automotive journals at university. Apparently the details were all worked out more than 10 years ago, so who knows whether it will happen now or not. Most hybrid cars have chosen to use much higher voltage for their traction motors, which would be unsafe for general use around the rest of the car. 42 volt systems would be more suited to 'mild hybrid' cars with start-stop systems on them.
