An Electric Supercharger that works

I was a sucker and bought an e-ram a couple years back. That piece of crap didn't do a damn thing. In fact I think it actually made my car a bit slower, my butt dyno's pretty good.
I was tempted to take a dump in it, wrap it up, and send it back.

15 seconds of about 6.5PSI I think I remember the article saying. 15 seconds use for every twenty minutes of charging doesn't sound like it's really all that great to me (IMO)
Sounds like it would work, and I'm pretty sure from what I've read and the pictures I've looked at that it would, but it's more cost efficient AND the weight issue is better with a turbo setup.

Temporary HP doesn't impress me I guess. A 2.5l engine that can make 300 HP all day long and last for years, that impresses me.

Some engines have to be built around it to provide the right platform for that use (just like high Hp NA engines and turbo engines need to be built around the NA or Turbo theory)
I have a friend with a pretty stock VW Scirocco that has run over $500 of 50cc of nitrous. Some engines are way underpowered and unexplored territory (scirocco) and some engines are running stock, pretty high in the maximum efficiency area (Honda) and so therefore those engines die from a serious (or a couple) hits of NOS.
an engine that is at 10% of it's max efficiency that runs NOS and doubles it's efficiency is still 80% underpowered. If you have a car that is 65% out of a 100% efficient and you put NOS on it, you cannot run your engine to be 130% efficient, the engine will die.
Talking to the Scirocco dude seriously taught me some stuff about the older, cooler, VWs and how NOS works in them.

That's pretty good. Another scenario I keep envisioning is a hi-helix type roots (ala whipple) driven via a miniature CVT tranny to provide variable speed. Man, if they could combine this together with a variable compression engine it would be awsome!

When they start offering the hydraulic driven supercharger in a kit form watch out.
Steady-state cruising at 15:1 compression and no blower.
As throttle is opened, the compression would vary down to about 10:1 still with no blower boost up to about 1/2 throttle opening.
Then from there up to WOT, compression would vary down to 7:1 as blower boost variably builds to a max of 20 psi.
It would be the best of power under acceleration with incredible economy for cruise.
