Electric Supercharger that looks legit???????

Electric Supercharger that looks legit??????? I don't think they make it for our car but I was just curious what you guys think about it. It is def not an e-bay piece of crap that's for sure. They have some kits out for the Mazda 626, Mazda MX6, Mazda Millenia.

here is the link: Electric Supercharger

You posted this link in the other thread. Eat s*** and die. LOL

it may work, but 20 psi would require the same engine internals and upgraded fuel management etc as running 20 psi with a turbo, and that's no good since it lasts only 15 seconds.

lol. my bad I'am bored that's the only thing I can say in my defense.

This one seems more legit than any of the others from over the years but did you see the load???? 15,000 WATTS!!!! On a typical car electrical system, that is 1250 Amps!!!!! Your alternator is good for 200 max in most cases.... And that is the STEADY STATE load; STARTING current will be 2-3 TIMES that....

In other words, you will need LOTS of auxiliry batteries to make this work, and you'd better be REALLY careful setting the system up so you don't blow out your electrical system the first time you try and run the S/C...

I am sad to say that I have some experience with these electrical S/Cs (young and dumb once, you know...) and even an 80 amp load is pretty big for most cars, to say nothing of 20 times that...

So how do you think they measure "zero parasitic loss"?:wtf:
Electrical draw on the system most definately causes parasitic drag on the alternator, and with that high a draw, on the whole electrical system...

 

[IchBinEinMP5]

Oh, are those starter motors x 3?

 

[changedman]

scap!! haven't seen you online FOREVER! where u beeN??

Its made by knight turbos. It will fall apart regardless of its function.

How is that ass still in business?

Like NOS, the ESC400 is designed for short burst use, but unlike costly Nitrous refills, a high-output 200-amp alternator upgrade (not included) will fully recharge the power supply after only a few minutes on the road. By installing a SDPT switch, you can protect your alternator while your system is running and recharge your power supply while you drive.

A fully charged battery set will yield a number of runs before recharge is necessary. We recommend Odyssey racing batteries, which allow for extremely quick recharging. Standard automotive batteries are limited to a charging rate of 30 amps, which means longer charging times. A standard alternator is approximately 85 amps. A standard automotive high-amp battery charger will recharge the Oddysey batteries in less than an hour. The ESC-400 draws 1250 amps, so at 100 amps the recharge rate ratio is about 15:1.

Warning: you must upgrade your alternator to a 200+ amp unit. Attempts to recharge off a stock alternator will cause overheating and possible damage!

Thomas Knight uses and recommends the Odyssey 680 racing battery. They weigh only 15 LB each and hold 680 AMPs.

where the hell would you find a 200amp alternator? a MAC ******* SEMI? they might as well say you need to mount a honda generator in your trunk

Only application....Racing.

 

[Mike R]

Wow, in addition to the electrical draw, that has to wieght as much as a complete turbo setup with IC, 3 starter motors OMG!
LMOA!

 

[IchBinEinMP5]

Wow... nothing like adding a crapload of dead weight for 15 seconds of ???

I have heard of a supercharger that uses oil pressure from the engines oiling system to drive the turbine...

I haven't looked yet, but does Jackson Racing have a supercharger for our cars?

 

[charles]

No, they don't.

This is Geoff Knight (Boosthead.com) the designer and inventor of the ESC-400. I saw several of you had visited my site and wanted to see what you were discussing. I will be happy to give any answers I can and am happy to accept any educated critisizm from anyone with REAL questions, instead of the two shi*-for-brains who gave some bad references to my company. I doubt if either of them know me or my company, but between them making the burgers at BK and washing cars at the corner gas station they probably dont have a 2nd grade education between them!!!

I have been building custom turbo and supercharger systems since before most of you were born. Turbos in the mid 70's were laughed at by the guys who thought carbs, intake, headers, and cams were the best way to go. So when I see people look at new technology I expect some scepticism until the well known companies start to copy it. What I find most amusing is the fact that over two dozen large corporations have contacted me about my design with their engineers offering congratulations on a fantastic new concept--so awesome that the patent office granted the design on my very first application. That is NEVER done. Yes the critics are largely uneducated burger joint employees with a 10-year-ol rotten import who has read somewhere that electric superchargers cant work.

This system does indeed work, and will blow any turbo or belt driven supercharger away on identical cars. Not ever close. So when someone says that turbos are better than superchargers they are not knowledgable enough to know the facts. All turbos are parasitic. That means they ALWAYS are causing a restriction in the exhaust. No matter what anyone thinks, the truth is that the average turbo has a 2.5:1 exhaust-to-intake pressure ratio at peak engine power. That means if you see 10 psi on the boost gauge, the exhaust manifold will see 25 psi backpressure. Is that not restrictive? Why does the exhaust temp go up 300-400+ degrees? A 16G Mitsubishi Eclipse at 15 psi is taking 32hp to turn the turbine shaft which in turn spins the compressor. Energy is NOT free, so if you think it is then you are fooling yourself.

Belt driven superchargers also take power to make power. A typical 5.0 Mustang runnig 15 psi on a Vortech requires just under 100 hp to turn the supercharger. Read that again!!! Just under 100hp.

So if an electric unit is designed to make reasonable boost and give good performance, the hp gains will ALWAYS be better--end of argument. Now some may think we run the ESC with the alternator. You will catch the alternator on FIRE if you do that!!! This ESC draws 1200 amps. It gets that power from lighweight racing batteries, and then those batteries are recharged AFTER the ESC has run while you are cruising. I get four runs in my car--15 seconds will get me will over 110mph. After the runs I drive for only six minutes and I am ready to run again.

Feel free to ask me any EDUCATED questions and I WILL answer them.

You have one slow car...

So 5.0L Mustang will loose more power with a SC than it had before?

atsturbo:

Don't sweat it, congratulations on the first (that I have seen) electric supercharger set-up (real). I'm glad to hear that things are working well, and am willing to concede that you probably have more forced induction experience than myself (or most of those on this board). However I believe that either our end goals are slightly different or you just have not come to that stage in product development yet: namely a street application, with the capability for constant and consistant use. I do realize that your system is aimed at the drag strip, and that your claim of no parasitic drag is correct, if you discount the power needed to recharge these batteries. Again, no big deal on the drag strip, basically equivilent to a shot of NOS, but hardly practical for extended periods (as on a curcuit track).

Is there any possibility of a version that runs similar to a conventional supercharger in that it runs on demand, for the street or track? A system like that would use some sort of generator, which under load would create parasitic loss to a similar amount to a belt driven version, no? I have also heard of a turbine that uses oil pressure from the engines lubrication circuit to turn, again with similar parasitic losses. (Or even a seperate pump/hydraulic system) The intriguing part of both these systems is the ability to mount the charging unit almost anywhere in the engine compartment, regardless of the exhaust or ancillary belt positions.

Actually, the charging systems from the Hybrid cars on todays market may yield the kind of outputs needed to run such a system... have you looked into something like that?
