What did you do to your GE fit today?
Sorry I missed it then, but yes those are a joke like a few other things I could mention. Those are basically a fan thrown into the intake.

The real deal only took a decade. Still not for sale. Maybe I need to write them and concince them it would be a good idea to send me an evaluation unit.

I would rather just use that energy with an electric motor or two mounted in board with a cv shaft to the wheel hubs on our rear axle for short bursts.
IMHO the energy/weight is not worth it to power some sort of FI device. It would otherwise still restrict the intake tract, even if it is freewheeling via an EM clutch when not used.
I would wager that is why we will never see one of these on a passenger vehicle. OE or otherwise.
Just my .02. They'd be fun on a go cart though...

I have to look into that. Its wild as long as the extra weight don't counter the extra power but its different.
Edit: Made 5 psi of boost go for 2.5 seconds off the stock time. He had traction problems though but it worked.

Yea, but it works. I found the magazine its in.

No doubt they work.. but they are pretty crude, have a huge electrical draw and require multiple 40+lb batteries and an alternator out of an escalade.
For the cost you could go full time FI and not worry about having enough juice to taze an elephant.
They also can't keep boost up to redline.
Boost is a measure of restriction, which in this case is telling you these are pretty low flow capacity compressors.
Not trying to be a debbie-downer, but there are so many more cons than pros. Which again is why you'll never see one of these OE and even most ricers can agree to throw down that much cash for what is basically a nitrous alternative is silly.
Not only that but most ECUs use the deadly fuel cut version of rev-limiting so you will be melting shit in no time. Valves, pistons, bank accounts..
Edit: You are also putting any and all emergency responders at risk of electrocution by installing one of these in the event you crash. Same thing goes for Leaf and Prius owners. Don't believe me? ask an EMT/Firefighter...

If you had a electric race car it could be as fast as any super street turbo car. Your right its more dangerous with electric. I seen that on Top Gear.
Boost is simply trying to flow more air than the engine can swallow.
1bar boost is literally double the mass flow that would normally be possible. The reason boost tapers off is because the engine is catching up to the compressor's ability to feed excess air.
This is a very rough approximation of what is happening.

Thomas Knights design works but the future is in Centrifugal Blowers. The thomas knight design uses inefficient motors, an inefficient blower, and alot of power. The blower has a very high rotational mass but it only has to spin at around 10,000/20,000 rpms. At the time he was designing it, it made sense. But now that we have brushless motors that are becoming more affordable and can spin up to 100,000 rpms, powering a centrifugal blower makes a lot more sense and requires a lot less power. Namely, it requires no additional batteries. Just one valved AGM style battery. So the additional weight is only the weight of the supercharger and motor. ~30lbs.
Restriction really isn't a concern when it runs at WOT. The only time I care about restriction is at WOT, and it always runs at WOT. However, if it was a concern it wouldn't be hard at all to design a bypass.

HELLO? Can you hear me now?
Man I hope you like hearing and you don't have any teeth fillings. That thing can dissolve kidney stones from the looks of it. HELLO?

PS... on topic... Just hit 2 years a few days ago on the FIT. woohoo... still lovin it.



cool.
