anyone thought about these things. www.electricsupercharger.com

I put MSD and Jacobs ignitions on jeeps, boats and hotrods and they claim on the dyno you only see a tiny gain. OK, but the drivability and throttle response is great and it's worth every penny just for that. I modify my air inlet temperture sensor on every computer car I ever owned. Did it gain a lot of power? No. But I can feel a snapper engine and I have the satisfaction of knowing I improved somthing. Same with adding a K&N or drilling out your air box for more air. Does it help alot? No. But at some RPM ranges you can fell a difference. Same for a throttle body spacer or fancy spark plugs. The may help a tad at a certain load or certain rpm range and you may percieve a difference. All good.
Now lets look at the electric fan/Marine bildge blower/Esupercharger or whatever you want to make it out of. At wide open throttle your engine vacuum will overpower the output of the blower and you will see no gain on a dyno. OK but what about part throttle or when the throttle is close and you first crack the throttle plate open. You will have a jump start of air going into your engin and you may feel a slightly more responsive gas pedal.
So this alone may be worth the time effort and money if you are the type of person that can feel his seat of the pants. Ever notice when hard wheeling the same guys allways seem to break and others never seem to break? Those that don't break may be a little more sensitive to the forces they feel. This is not really good or bad because those that break are somtimes really great drivers. So if you are the type of person that really went wow when you added a K&N,free flowing muffler, throttle body spacer,computer chip or any of the other modifications that don't really do anything then you will be happy with a fan in your intake.
Look at what a winning race team is doing on a weekday night.They are doing stuff like packing front wheel bearings, cleaning almost clean air filters,applying wax to the paint and all the stuff that won't help.Hmmmm.

I am inclined to believe most of what you are saying. I think the problem with many of these devices and mods, including anything that improves air flow, is that they are hard to measure on a dyno perhaps because they have little measurable effect at steady state engine speeds (?) which is partly because nothing is changing (?), but perhaps are more effective for a few seconds during heavy acceleration, i.e. a noticable change in throttle response!
You said "At wide open throttle your engine vacuum will overpower the output of the blower", I am not sure I agree with this, does this not depend on the blowers maximum capacity?
I would agree with this part "but what about part throttle or when the throttle is close and you first crack the throttle plate open. You will have a jump start of air going into your engin and you may feel a slightly more responsive gas pedal."
In my case I am looking for a way to get a few more HP out of my SD22 (Nissan) 2.2 L, 68 HP stock, diesel (Naturally aspirated with a pneumatic governor on the IP) that is my 85 Jeep Cherokee. (No I don't need a stroker, this SD22 is getting a good 34 MPGs stock for me). It is just a little bit light on power going up hill with the A/C on and multiple passengers on board, in other words when heavily loaded I have to drop down to 3rd or 4th gear from 5th gear even at WOT. I know some guys who are trying custom TCs on this engine, but IP control is a bit of an issue still for them. They have determined that the throttle body is a severe restriction even when TC it.

Go to a truck stop and pick up a gallon of lucas fuel additive for diesels. That stuff is like majic in my chevy diesel truck and my neibors small diesel tractor plus it adds the lubrication back in the fuel that is now refined out of it. Keeps your injector pump and injectors clean,lubed and happy.
