Oh yea that makes sense. For some reason I was mixing up supra for nsx so i wasn't thinking concept. I was thinking the supra was the next Japanese super car to come out.

did you mean people that don't know how to turn right?
even more special i don't think the charger is a terrible looking car. this version looks like shit. they took the one thing the car had going for it and ruined it... so sad. so dodge.
as i said on FB, no amount of power can make a charger not a shit car.

That Elio seems like a pretty good deal, and certianly more useful (and cheaper) than a trike or one of those reverse-trike-jetski looking things. Now, that being said, it'd feel pretty silly owning one in a state that requires motorcycle helmets (like VA). I saw a guy driving a car once with a motorcycle helmet on. I felt it was clear I should avoid that fellow.
*edit* Oh hey well look at that, they secured a helmet exemption for the thing in most states, invluding VA. Well good.

Sounds like they are comparing it to how much electricity they use rather than how much air they push. The turbos would push more air for the amount of electricity since they won't use any power to make the air hot.
Re: Automotive News Discussion - ScottyB - 08-15-2014
i'm still kinda surprised nobody went after a compressor driven off oil pressure. there was an article about that in Sport Compact Car back in the day.
they could utilize a variable speed electric scavenge pump just for the oil-turbo to keep parasitic losses down and keep the system somewhat redundant if there's a failure.

There are some hydro-hybrid, and even flywheel hybrid designs out there for trucks...they're just...not as safe as electricity, since the energy storage mechanism is only as good as its container.

IT SOUNDS LIKE THEY ARE COMPARING IT TO HOW MUCH ELECTRICITY THEY USE RATHER THAN HOW MUCH AIR THEY PUSH. THE TURBOS WOULD PUSH MORE AIR FOR THE AMOUNT OF ELECTRICITY SINCE THEY WON'T USE ANY POWER TO MAKE THE AIR HOT.

Not sure what is unclear about that, but let me restate.
They are saying 7 kilowatts is about how much electricity 4.5 hair dryers use. Hair dryers use electricity to both heat the air, and move it with a fan. The turbos would only be moving the air, so they should be moving more air with the same amount of electricity.
In other words, I'm just saying it seems like a dumb comparison for the journalists to make. It's not like the turbo can only push the same amount of air as 4.5 hair dryers. If that were the case, it would likely be a restriction in the intake rather than something that could create boost.
Re: Automotive News Discussion - Evan - 08-15-2014
7kw is an incredible amount of power. I had no idea turbochargers used that much juice (and i had no idea that the exhaust had that much energy either).
add on to that the fact that its just a supplemental turbocharger (well technically supercharger) that spun up before the conventional turbo kicks in.
you cant even power 2 hair dryers off one 15a circuit at your house without tripping a breaker and an electric turbo uses more than double that!
would be interesting to compute how many kw those leaf blowers generated in the roadkill video and compare

If that were the case, it would likely be a restriction in the intake rather than something that could create boost.I think they use that comparison not because it has anything to do with airflow, but because a hair dryer is a household appliance that uses a LOT of *electricity* that most people are familiar with, and thats the same amount of electricity used to spin the electric supercharger
they could have said....800 light bulbs or something..... but that doesnt really illustrate very well

I guess that makes sense, but it just seemed to me like they were saying it was only as effective as 4.5 hair dryers would be. Maybe that wasn't their intent.

You could also say "9 ish horsepower".

If I ever see one of those on the road, I probably won't notice it because it doesn't really look like anything special compared to the other models.

I'd pass on the Bentley and Viper.

That will be a screamer and will likely eat up everything else in that segment with that gearbox. SVO is legit!
