Random Idea time...

So im in the middle of class and im the only one in here other than a substitute and a teachers aid. Why might you you be wondering (though you probably aren't)? INSOMNIA and an AP test. Yeah bad mix. In my less than ideal situation, I've had some time to muddle over some ideas.

Rally Spiders . Topless two seaters that get messy. The idea is that there would be near flat~ish tracks (there's still going to be jumps and ditches). There would be less roll cage since the weight would lower and there would be less of a chance of rolling. It's pretty much Le Man's racers on rally courses. The ground clearance would obviously be higher but still low enough that rolling is less prone to tumble.

Bridges and near vertical turns . Downforce centric cars that stick turns that are nearly vertical and tracks that over lay each other to be compact and add some cool in car shots. Most of us all ready know that, f1 and indy cars make enough downforce at 200 mph that they can drive on ceilings comfortably. With the vertical turns its less downforce and more aiming based on gravity's pull. The turn would not be so angled for safety reasons and there would be adequate precautions if some thing were to go wrong. Both are for compactness and interesting additions to racing though the turns are to be able the go around a relatively tight corner at top speed. No loops de loops, no jumps, no hot wheels stuff just racing without taking up too much space. Oh on the turns there would be low pull magnets to help guide the car through a turn without messing stuff up. Ooooorr there could be a lot of space taken but have most of it overlapped.

Electric Supercharger . No not that stupid hand fan bullshit, but an electric motor matted to the compressor end of a turbocharger. It doesn't have to be near the exhaust so the motor doesn't get wrecked and the compressor can be made lighter (the photo to the side is just to show an example). Plastic is not what i mean by lighter i mean CF or the like. No lag, instant power, and placement flexibility. I know that BMW has a patent for an electric turbo, but that has a flush of issues tied to it. With this (so long as it's done right) could make or break a track record.

So what do you think? Potential? Dangerous? Retarded and Dangerous? If i were to be a driver on the track I suggested I would possibly piss my self at first, but after a change I would go for another run...anyways.

I approve the idea of steeply banked turns. I would also appreciate the trickle down of that technology to the local on/off ramps.

Vishnu is on this one. They are putting kits out for the FRZ and the NC Miata.

Good to know thanks

What sort of insane motor would be needed to drive the compressor at the required 10,000 RPM or so?

From what I remember reading about it, its a brushless motor powered by two 12V batteries that are wired in series to provide 24v to the motor, with a third 12V battery powering the starter, I believe they are using LiPo batteries to provide the umph for the compressor. But it isn't an always on sort of thing, more of a boost on demand system. From the dyno charts Vishnu is releasing, at least for the NC, the torque gains are ridiculous because you are not robbing the engine of any power to run the compressor so a low boost of say 5 psi can net power gains of say 10 psi (note I'm ballparking that and pulling it out of my ass don't hold me to those figures. . .).

Lemme see if I can find the thread for the NC kit.

Here is the thread they put on Miata.net. . . That will probably do a better job answering questions than I can as the dudes from Vishnu are the ones who created it.

The biggest advantage I can see for these is that you could pretty easily add it to any car that has internals strong enough to handle the boost, since you don't have to re-work exhaust plumbing or anything, and the turbo could be placed away from the engine so it isn't heating up incoming air, because cold air = more power yo.

I really want one of these for my Buick.

Yeah, you just need an engine management system capable of changing the fuel and timing maps when boost will be applied. If I remember correctly, they are only pushing 5 psi and saw a 60 Lb/ft and 50 hp gain, that is pretty ridiculous. They also state that they haven't run the batteries that power the motor down all the way during driving, but I don't think they've done any track days with it yet. It sounds promising and it honestly could be one of the best ways to make power, especially as brushless motor technology and battery technology advances. The only thing I'd have concerns about would be the service life of the motor powering the compressor.
