Volvo 4-Banger = 450BHP

[flipstah]

The Drive-E Powertrain uses two parallel turbochargers which are fed by an electrically powered turbo-compressor. That electric turbo's compressed air is not fed to the cylinders, but rather used to spool up the other two parallel turbochargers. Volvo says this "triple boost" means lots of power with no lag.

They heard we like turbos, so they turbo'd a turbo so we could spool when we spool.

Excited for the aftermarket potential of the eTurbo's.

"Electrically powered turbo compressor"

Doesn't that mean supercharger?

Centrifugal superchargers are just turbos iirc from work things...

supercharger would be belt driven, turbo is exhaust driven... so...

i blame ebay

Snipped from http://www.superchargersonline.com/i...age=page&id=19

According to Merriam-Webster's dictionary, a supercharger is defined as:
"a device (as a blower or compressor) for pressurizing the cabin of an airplane or for increasing the volume air charge of an internal combustion engine over that which would normally be drawn in through the pumping action of the pistons".
A turbocharger is defined as:
"a centrifugal blower driven by exhaust gas turbines and used to supercharge an engine".

According to Webster's, a turbocharger is included in the definition for superchargers - it is in fact a very specific type of supercharger - one that is driven by exhaust gasses. Other superchargers that do not fall into this category - the kind that we are all used to hearing about - are normally driven directly from the engine's crankshaft via a crank pulley. So in reality, it is not fair to compare all superchargers to turbochargers, because all turbochargers are also superchargers. For the purpose of this discussion, however, a supercharger will be considered all superchargers that are are not driven directly by the engine, while turbochargers will be considered all superchargers that are driven by engine exhaust gasses

But turbos use the engines exhaust as it's power-supply.

I consider vehicle turbines as waste-energy recovery systems (convert waste heat into mechanical force) whereas superchargers require direct engine effort to create output.

Using the engine-driven alternator to power a "turbo" would be the same in my opinion

But an alternator doesn't have "waste-energy", in fact it has to work harder to output the electricity needed to power the compressor.

Alternators have "waste energy" when the vehicle is coasting. Depends on how the electricity is being manged for this device.

outside of the hybrid element on the crank, is this not very simluar to the idea that exist with the current F1 engines?

Alot of cars are disconnecting alternator when the battery isnt low and engaging during braking these days.

All efficient dynamics BMW's do it its pretty nifty.

The car really can coast when it disengages tranny and alternator. Surprising!

I've been curious for more specs on this motor.
There's only one picture that shows the eTurbo or whatever Tik-tok wants to call it.
It's off the intake side so I wonder if behind the air filter there's a type of check valve so air pressure can build up?

It's gotta be the same type of setup that Toma was testing out for the guy starting the Echarger business, no?

Toma was actually using his car to test for the guy? What ever happened to that guy and the thread? Did it actually make any noticable gains?

He dyno'd a few, and was impressed with the gains. They're small but noticeable.

The Phantom Superchager from this thread?

This just in. There is already a production Beemer to combine parallel and sequential turbos. And 50 lbs of boost

Really cool, looking forward to seeing this technology on some road-going cars.
