It's not true that an electric supercharger will have none, though. There's a weight penalty for the batteries; and if this runs off the trucks alternator - much more drag on the altenator when it's putting out the power.
Lead, follow, or get out of the way

I have been thinking about using a leaf blower, just put it in the back run a pipe to the TB and use an electric triger to rev it up when you want extra power. I know, I have some weird ideas sometimes, but I think if the computer can feed it enough fuel, it just might work.
Or could use an extra fuel pump to feed it some more fuel.

As the author of this thread,
1. dakota49- the leaf blower will never blow enough to really get you anything.
2. the blender idea- now thats funny!!

You are still talking about a triple conversion; electricity, to mechanical motion, to air pressure. That means triple loss. Your better off taking a page from the high performance hybrids and using your electric motor to directly turn the drive shaft as an assist to your gasoline engine. that way you are only incurring one loss (electric to mechanical).

That sounds just fine but remember you will get more of a gain from more air being pumped into the engine with more gas flowing. Otherwise why would blowers work off the crank. Mechanical to Air to Mechanical. Using your theory having a blower would give you less horsepower :)
Anyway, your idea isnt bad but how do you incorporate that power. The amount of torque would shread most belts and the only other way I can think of would be to use a clutch and chain which sounds like a huge pain to figure out how to incorporate it into the drivetrain. Seems like a lot more people could figure out how to wire in a relay, controller, batteries, motor and a couple of pipes.
I have done more research over the past few weeks and it might be a few more years off than I first thought. Im still sure it will be possible in a cost effective manner. I previously didnt think that controllers costed so much :(

In the case of high performance hybrids, the motor shaft is actually the axel of one or more drive wheels. Direct electric to mechanical conversion applied directly to the wheel. a single conversion with no mechanical losses (you've already got to have the bearings that would otherwise not be inside the electric motor). True more pressure means more power within reason, but add the weight and conversion losses of an electric blower and I just can't imagine a system that could overcome it's own losses. A blower is efficient because it is relatively light weight and your primary in-efficiency is in the friction of the drive belt. The hybrid systems primary in-efficiency is in the electric to mechanical conversion in the electric motor. However, electric motors have become VERY efficient (80% and better is not uncommon in advanced motors currently on the market) converting very little of their input energy into heat. Unlike a blower which adds relatively little drag and weighs very little compared to the boost it creates, your rube goldberg pipe-dream would likely be inefficient and heavy. It's possible you might realize enough gain to overcome the losses, but by how much? Is it really worth a slight gain for the cost and maintenance issues? As someone said ewarlier, it might be fun as an experiment, but it is extremely unlikely to produce a practical system.

Rube Goldberg lol. This system sounds so simple to me. Chain a couple of lithium Ion batteries together, attach to a controller, attach that to the motor attached to the turbo. Then just run a line from the tps to the controller so it knows when and how much juice the motor needs. Simple enough for a freshmen to do.
As for weight. Batteries weigh 1/2 per volt what they did 10 years ago, motors have also drastically dropped in weight. Do you think they are just going to stop dropping?
Rube Goldberg LOL. There is almost as much wiring in a properly setup nitrous system. Or are those Rube Goldberg inventions too.

There is a 50hp electic motor on e-bay right now you guys should try.
Nimh batteries are better than lithium ion.
