I have spoke with this Geoff Knight guy for a quite a while now. I actually had one of his earlier T04e prototypes that made about 4 psi of boost for like 6 seconds at a time. He has been boosting cars in everyway imaginable for a long time. Geoff has always been in seach of the non traditional boost. Check this site and see his latest invention it is sure to change things in the future especially about the way some look at electric superchargers. www.boosthead.com

Don't forget to check out the ad that is going to be in TurboMag and maybe SCC in the next 3-4 months. I also have an email he sent me which I can forward to you if you want a better explanation of this setup.

 

IBTL.

and let's see them prove it first.

 

hmm...that Knight name rings a bell...didn't someone post this awhile back?

 

..............

 

It actually looks like a viable setup since it's running off of a separate battery setup and it would only run at full blast for ~15 sec at a time. I could see something like that working. But the price tag is kind of scary, $2995. For that kind of money, you're pretty close to a full time conventional turbo or SC. Even a loaded out nitrous kit isn't more than $1500 or so. I guess if you planned to use it a lot, it would even out when compared to nitrous refills.

 

This is for real, I know the costs are relatively high now but in the future and larger firms are able to mass produce this with economies of scale it will be a viable alternative to N20. Check the link and at the bottom there is a link to the ad that is going out in the national magazines. Again feel free to voice your opinions but the guy that developed this piece has more boosting experience than anyone on this board. Take a look as this is a working unit. I guess watts can really equate to HP.

 

yeah but for 3Gs, might as well do the real deal that won't have that 15 second burst limit.

 

This is the first one of its kind, eaton blower, electrically driven. You have to go to www.boosthead.com and go to the bottom and look at the ad, there is a link there with some decent pics and blow it up. His piece of sh it chrysler 2.5 avenger gained 100+ whp at just 6psi. Instant boost at wot at any rpm and no drag on the engine whatsoever. The price is if you want it right now, imagine that will drop by at least 40% once these things get more mass produced. I just think it is awesome, one of a kind, revolutionary.

 

yawn. wont work. sorry.

 

Actually quite possible, check out www.turbodyne.com they have applications for trucks that provide some boost before the main turbo kicks in. I was looking into this about 3 years ago. So it's definately possible, however how probable it is, is questionable, the actual piping wouldn't be that hard, but the battery/charging system would be a pain. And then on top of that, the price tag really kills the setup.

But then again, at the time when I called that company up they did seem pretty interested in trying something in something smaller. However, not all electric boost options are crap, those on ebay, yah most likely, but there are viable electric boost options out there, it just seems that they aren't cheap.

You guys that think this won't work are delusional. All you have to do to get boost is force air at a higher pressure than ambient into the intake manifold. All you have to do for that is get something spinning fast enough to force the air in there. It doesn't matter whether you do this with exhaust gasses, belts and pulleys, an electric motor, or the Force. It's all the same principle. Granted this is brand new and may not be worth it right now but I agree with AllGo as the price comes down on things like this they will become viable boost options. Anyone ever heard of the hydrocharger? It's a turbo but instead of having the turbine side driven by exhaust gas it's driven by fluid pushed by a hydraulic pump. It's all boost guys, you just have to get the compressor spinning fast enough, it doesn't matter how you do it.

BTW Thomas Knight has been doing force induction for years, he developed a twin turbo kit for the Probe GT/ MX6 LS when I was into those cars.

 

Even if it could work.....I'd rather go w/ Nigel's kit.

 

No doubt, with the current pricing for this type of technology most people will still opt for the traditional turbo or supercharger kits. However, this technology is here, it just seems to be very slow in development. When it does finally get here, it's going to be, interesting.

wow... 15,000 watts. Thats a ton of power to pull from a battery for 15 seconds. I wonder how long the recharge time is and how long the battery charge lasts. For that matter, how long till you have to replace the battery itself.

And yes, this is a viable boost option. I wouldnt pay more than about 1000 for it... but with all technology near its inception time, it's pricey.

 

If you're going to post like that and in no way contribute to the thread - then don't post at all.

If you're going to say it won't work - then tell us why....or STFU.




It's a new and interesting method.

Not that I would buy one, as we already have 2 viable options for boost somewhere near that price range (Turbo/SC).

But for other hobbyist with other cars that want something unique, it might be a neat investment. Or people with unlimited funds that just want to be different.

And yes - it would work.

 

15 kW is what, about 20 hp? (746 W per hp, I believe.) That's sufficient to move 500 cfm at 9 psi, which is significant.

 

Hmm for these 15 or so seconds I presume this price....also includes the much needed extra fueling issues to control detonation.

 

Thanks for the positive input Ian. I hate when people think they know everything and just make themselves look even that more ignorant. This system is still new and still going to take some heavier scale production but I assume that the price will prpbably come down. The need for a good eaton blower core will not be cheap. I said before I had one of his first prototypes that was basically a T04e that had a 2400watt motor. I ran to 4 12v lawnmower batteries and to one starter solenoid that was triggered by a microswitch at WOT. I assume it was drawing like 100amps at that voltage and I could occasionally read 4psi on the boost gauge at around 2500. As the rpms increased the boost would tail off quickly due to the injestion of more air. It was still fun but the batteries I was using were twice as heavy as the newer Odyssey units and did not discharge nearly as well. This was only like 3hp and the new is 5 times more powerful. The Odyssey 680 batteries can discharge very quickly but after about 5 good 15 second runs it would need recharging and these can be recharged hundreds of times . I like the idea and it will definitely be a viable option in the future especially the fact that it bolts on, ads minimal weight, can be charged by the vehicles charging system with proper isolation, or the common deep cycle charger at home and can be recharged for pennies not $40 for a 10lb N20. I still think you guys need to go to the www.boosthead.com and go to bottom where it says click here for the ad. You can blow up the actual unit and see this isn't some bulchit. Those 3 starter motors working together that when engaged instantly gives boost within a fraction of second whenever you go wot. Its a dam good invention if you ask me. I know Geoff is very excited as he had pretty much sold every traditional turbo piece/system/parts he has to push the development and marketing of this.

 

Ouch Shawn....gonna take that?


No it wouldnt work.

 

Yeah he will - he knows better.....

 

I'd like to see someone do it and then see a dyno or a video of it on the track.

Until then.....

Not saying you or anyone else is wrong....just my opinion.

 

OK then....that's fine.

Please state why your opinion is what it is instead of just posting that you don't think it will work - just saying it won't in your opinion doesn't help the thread at all.

Hell - you tell me logically why it wouldn't work, and I just may agree with you.

But something tells me you know too little about such things at a mechanical level to post a valid answer, and you're trying to egg me on because you and Mr. Gone are lovers.

 

 

This is the same guy who isn't quite sure the difference between wastegates, BOV's, turbo specs, boost controllers and so on or even how boost in any form works.

Definitely defending a lover here...

 

Yea...lovers - great one. Well - of you look down a few threads....you'll see a similar type thread that got locked. To me.....an electronic supercharger wont produce enough effiency through the engine and the blower itself to create boost that will significantly make a car faster and have more torque.

Jeff - You think I dont know what a BOV does? Or a wastegate? Was there ever a time in your life when you were learning a lot about turbos/sc'ers? You think information just comes w/out asking questions? Go on somwhere w/ your audiobahn amps. Jeez Thats all.....


I've got more boost shootin out my @ss when I take a **** than that electric POS.
