Electric supercharger and turbo
 

Has anyone tried this? It seems like it could be a very cool setup. This makes a turbo with almost no lag... Thoughts?

Maybe you should have a look at this long thread, which is almost always on the first page of the Forced Induction section...

I have looked at that page, although I haven't read all 400+ pages. That is the electric supercharger part, I'm talking about an electric supercharger combined with a turbo. It just seems like it would be a cool setup and I wondered if anyone had tried it.

Well, in the mr2 world we call that compound charge. It has been done with the '88 mr2 supercharges ones.

Then only problem is heat. Great for drag and one lap time attacks. But after 3 hard laps it's heat soaked.

It may favor the FR layout better since there is more cooling options. But you still have to deal with the massive heat

I don't know if anyone tried both together, but it would be overly complicated like any twin charged system. It is also unnecessary. A small turbo can spook at low rpm and have great transient response. A big turbo driver isn't going to play around at 2k rpm anyway. All their real power will be way higher in the rev range.

Audi, Volvo and BMW have electric supercharger and/or assisted electric turbo chargers in the pipeline. Toyota is rumored to have a pure ESC in development.

In the aftermarket, yes also. It's been done in the early development days of the Phantom ESC system. Here are two early versions of Robftss Phantom ESC (TQ180 and TQ240) run in series with an Eaton M45 supercharger. This was by @Wild Weasel testing for drag applications IIRC. More info on his website here: http://www.wildweasel.ca/HowTo/Auto/eturboTest.aspx

Additionally @Robftss has tested two Phantom ESCs run in series together (one blowing into the other). On the test bench it works. I don't think much additional development has been done. Can't find the picture right now, but it's in the main Phantom Supercharger thread on this board.


Finally @Shiv@Openflash is developing two ESC's running on an Audi R8. Not sure if this is ever intended for production, or if it's just a fun project.
