This has been done by someone on the Integra Forced Induction forum on hostboard already. He plumbed an A/C output before his JRSC giving it the cold air before compression. It was a couple years ago. I'd do a search, but I'm sure it would be hopeless finding it now. Judging by the number of people that followed him, you can see it didn't work out all that well.

 

Hey, guys. I know it's not cutting edge, but some of the turn 2 and whatnot /C Car motors run off of 12 volt systems and can spin to 45k RPM... Turbo's are balanced to 140k RPM. With a little gearing and a nice belt system... I can see a larger version of one of these little motors making a blower make actualy bonafied boost...

But thanks for stealing my Freon Idea, too, Geezer...

 

Touchy, touchy, ain't we

It's fine to discuss so-called "theories" but one would think that the majority of people responding with facts that refute such a theory would provide adequate information to sway your opinion.

How about this:

Your idea's ground-breaking and worthy of envy, shattering over a century of internal combustion theory, research, and development. Now make your concept a reality!

Feel better now ?

I've modified my post to provide attribution for your freon idea. Trying to keep your tenure, or something?

 

>>Oh yeah, you can use more that a twelve volt system with a transformer , but I don't think that much power would be needed.<<

I'm no electronics wiz, but voltage isn't the only consideration here. Amperage is going to be static, so no matter what you do with a transformer, it won't spin a motor powerful enough to come close to a turbo or crank shaft driven SC.

The E-ram deal certainly is a rip, but not becuased they used a wimpy electric motor. I believe they *tried* to do a good job. There's a video of them blowing one of those fire logs across the garage floor. IMO, that's an impressively powerful electric motor.

The "FI device" (or whatever) is still relying on energy obtained from the motor in the first place. Either it comes from the crank shaft, exhaust gas, or the alternator. In the end, the most efficient (and easiest) method wins. IMO, it will never be more efficient to use the alternator to obtain the energy necessary to spin a supercharger.

But, "prevailing wisdom" just sits out there waiting to be proven wrong. So go for it.

 

I'd say substitute a gas blower for less amperage drag. http://www.bimmers.com/m3/hoax/

 

Well, it looks like it is already out there. Check it out, a "real" electric turbo.

This was at the turbodyne website

about how much heat would a turbo be needing to dissipate here? I need numbers for specific conditions...Give me a "full throttle" number or something like that eh?

For this, you could do one of three things:

1. Get a good intercooler and not worry about it...
2. Get a good intercooler and cool it further through a HIGH-POWER a/c system
3. Get a good intercooler and cool it by other means (peltier-effect or water-radiator or both or other)

Need to know how much heat this is though..otherwise all of this is useless...

I also need to know how much power is taken away from the engine with a high-power A/C (there are some that can run constant load)... Or maybe, about 1KW of electrical cooling power? How much of a power hit is that?

I suspect that keeping it simple with just a NICE intercooler is probably the best for us all...daily driven...
