Seems like a good idea, wonder why it took so long.

So, has anyone ever tried to use the exhaust gas pressure to run an alternator?
It seems like an obvious choice to generate electricity ... (IMG:style_emoticons/default/idea.gif) |

I think those "electric turbochargers" were mentioned in Pano recently (it may have been elsewhere, but whatever)... with the added note that they require 48 volts. (IMG:style_emoticons/default/blink.gif)

QUOTE But exhaust is a byproduct of a running car and does not steal any horsepower. (IMG:style_emoticons/default/confused24.gif) But they do indeed cost horsepower, they create back pressure. Nothings for free in this world, if you spin the turbo with an electric motor you’re going to need a bigger alternator, which is more drag on the crankshaft. This is why people that modify engines for a living use dynos to see where the gains and losses are. And without a turbine spinning the drive, I believe you are left with a supercharger… |

Technically, a "turbocharger" is properly called an "exhaust gas-driven supercharger". Other types are commonly called "belt-driven superchargers". A turbocharger can only be legitimately called such if it is a turbine which is driven by exhaust gases. The product in the article is properly called an "electric supercharger", not a turbocharger. In reality, nearly all that crap commonly defined by the term "turbo" fails to meet the test. Ya know, things like your deodorant, your electric toothbrush, or that scam to boost the speed of your computer software.

turbo (exhaust gas driven turbine) steals horse power as it makes its harder for the piston to push exhaust gas out the head rather than it freely flowing out the head ...

It's not a new idea, it's a new requirement. Government keeps increasing MPG standards, new widgets are added to meet them.

I have always wondered why there isn't a easy, simple, and cheap turbo option for these VW/Porsche engines. There are hundreds of thousands of engines sold from the 1960s to the 1980s, so you'd think there'd be a market. Miata has bolt on turbos for for relatively cheap HP increases. Why not us?

Just get one of these and be done with it. If you're running dual webers should buy 4.

Yes...Turbos use some horsepower (back pressure), but the idea is to gain more than you use....IF you only want normal aspiration (barometric pressure to fill your cylinder) you will be limited by altitude (mountain driving) hot humid days, possible engine life issue from over-boost and heat, etc......little extra BOOST will help engine efficiency.....but there are always costs.....It is up to you, what cost you are willing to pay.
It is all fun for the adventurous |

From what I have seen the electric motor was used for spooling up the turbocharger only. A turbocharger recovers wasted energy, "heat" to create H.P. They consume very little power at most lower boost levels, as the exhaust is doing downstream, with or without the turbo. I read about this being developed for OTR diesels a few years ago. |

Ya caint turbo a 914. (yeah, dave beat me to it)
and iffn you think the exhaust to run a turbo is free, shove a 'tater up yer exhaust pipe and drive around the block. As fer an electric turbocharger, it's a good thing batteries are really light .......... (IMG:style_emoticons/default/screwy.gif) |
