Thomas Knight Electric Supercharger

[psychlow]

Alright, guys. I know this is the dead horse. But check it out, there's a new bad boy with an electric supercharger. And, it isn't a leaf blower or a fume blower. We're talking nearly 100WHP.

For those of you that subscribe to Turbo and High Performance magazine (www.turbomagazine.com), check out an article titled "Boost for the Hard Case Cars" (June 2004, p.80) regarding the Thomas Knight Turbo Electric Supercharger.

It works by charging extra batteries off the alternator (either 4 car batteries, or, if you have an upgraded alternator, you can opt for lightweight batteries). When you flip the switch, you get a 15-second nitrous-like boost. When the batteries are drained, the motor stops, but guess what? To refill, you simply drive for a few minutes. Meaning NO REFILLING NITROUS.

Oh and guess what? No parasitic drags on engine power whatsoever.

Dyno results on an automatic Nissan Altima:

Baseline: 115.9WHP
Charged 1: 177.1WHP @ 5PSI
Charged 2: 208.8WHP @ 8PSI

And, electric supercharging is in its baby stages: when cars go to 42V power systems, it's possible to have a 1:1 discharge/recharge ratio with some work.

(PS - there's also a $1000 belt-driven supercharger kit for the 420A on that site....)

Discuss.

If you're looking to blow $150 on something you already know is useless and stupid, why don't you just send a check to me? I've been told I'm stupid and uselss many times over. I'd go so far as to say I'm stupider and less useful than any electric supercharger, but I'm not so dumb as to just throw $150 straight into the shitter...

 

[ShadowWulf]

Boat supply store eh? Humm id have to check that out.....


And as for KNOWING its useless and stupid.i DONT know ut, i suspect, MAYBE, it may be, but no i dont know. And hell, if it DOES work as advertised then its actualy a pretty decent upgrade for us NT guys for the price, no? Besided, my only doubts are from some people on this site saying there not good, yet nobody ive asked has actually TRIED one, they just assume. So hell, why not?


Back to the boat supply store thing, why would they carry them> And for so little money? Do they move the same volume of air?

 

[yup talon]

the project sounds fun. id be intrested to see your results when finished.

i was reading the add, and almost laughed when they tried to make it sound like this was waaaaaaaaaay better than using a real supercharger

and i quote...

Most superchargers require extensive modification of your engine - including additional belts and pulleys which actually drain horsepower from your engine just to run (you've heard of this - it's called inefficient.) All belt-driven superchargers need horsepower to run--sometimes as much as 20 percent of engine’s total. This is where an electric supercharger comes in - it requires no extensive modifications, and better yet - no belt to rob your engine of horsepower! This supercharger draws its 12 volts off the power that your alternator is already making!


:laugh: :laugh: :laugh:


still curious to see results though. good luck

If this thing turns out to help us that will be really nice. I will not flame you I will praise you for trying something everyone elso is afraid to because they do not want to be proven wrong. Get the supercharger cause I would really like to know if it works and for only $150 if it helps as much as an intake I'll probably get it.

Pity no fish bait has ever been so effective. We'd never need to raise cows.

Let me try to make the most obvious explanation visible to you: Are you aware the amount of power that supercharging takes from the crankshaft? Have you seen street turbochargers, and how they run twin V-belts to turn them? How about dragsters, with Gilmer belts the size of snowmobile tracks driving the damned things? All that rubber's not on there just because someone has a fetish for a bit of the black-and-stretchy. It takes a helluva lot of power to feed an engine. Now, you see that dinky little wire going to that "supercharger"? If it were possible to run enough power to matter, you'd need a cable the diameter of your finger to carry it.

For christ's sake, don't waste your money and our time with this pointless bunch of bullshit.

 

[jott5555]

i havnt personally used them but a friend has on his porsche 928 ( he had one in each intake runner and one going into the air box) he noticed a gain from it.. i didnt ride in his car but he was very impressed wiht his setup.. and he pulled one out and pushed a peice of wood around like they do on the electric superchargers site.

i think that your going to see a gain on na car.. and i havnt heard of one person on this site accually testing the product. i was going to slap 2 of them on my 300zx but didnt.. if you going to buy one go wiht the one from www.electricsupercharger.com those seem to accually have some sort of enginnering going into them

LET US KNOW WHAT HAPPENS.. I WANT REAL FEEDBACK!

if you look on their site.. at this dyno sheep specifically. this i was at that meet at devek and somewhat remember his car running.. i didnt pay too much attnetion tho. but there clearly is a gain.

 

[Defiant]

you should also blow a lil more money on a tornado thing you put in your intake track to better spool your air..

I only hope you were trying to kid around.

"Spool your air"? What in the hell is that supposed to do? Hell, for that matter, what's it supposed to mean?

 

[jott5555]

yes i was being scarcastic.. those tornado insert things you see on info commercials at like 4 am.. just total garbage.. but.. the eram thing.. im interestedin seeing results on a NA.

 

[ShadowWulf]

Defiant, i figured it was worth a try since NOBODY has actually tried one of these things on here to my knowledge (most of those links were about conventional SC's or just heresay bro, nobody had any concrete results) Thats my goal, concrete results, so at least we all really KNOW, and dont just assume.

And if they suck, so what? You can link to me next time someone asks this and say "Dont be a doofus like this guy".

 

[thekellbeast]

1. You're poor, so save your money for something that will actually WORK
2. These ebay superchargers are really bilge exhaust fans for boats
3. They WILL NOT WORK
4. Yes, people have tried them, on various vehicles. They didnt work. Putting it on an eclipse will not magically make it any better
5. You're also an idiot, if you ask this sort of question, read the answers you're getting, and STILL want to buy this POS
6. Go ahead and buy it. A fool and his money are soon parted.

 

[na90dsm]

very talked about and flamed subject. thats liek saying your decals gave you 50hp. get over it dude. you will not gain anythign from this. also use search for ebay supercharger. lemme knwo what you find out. i knwo it will be nothign but explained answers from people trying to talk you out of it. i have seen defiant in many of those threads with the same reply every time. look before you post

 

[speedy13]

good luck man,I don't think it will work either.look at his feedback.why are his items in private?and some people on his feedbak saying it does not work.It is your money and you can do whatever you want with it,but you could also get an UDP,TB,port your intake mani,or even a header for all that money for an actual mod that works!Hell you can even buy a screming demon coil pack and wire for that money if you wanna spend money for little or no gain. just my .02

 

[IceDragon]

if you all read, those that are flaming him... he obviously states that he is doing it for research, i say let him, give him encouragement if he has the money to do it and the will to follow threw... go head man, i want to see some results, i would think more air in means more horsepower, than again maybe these fans aren't strong enough to force any in... who knows, your results will prove all...

 

[na90dsm]

why do you think these people are trying to stop him. its been researched and failed horribly. do a google search for it. youll find a million tests

 

[yup talon]

by the sounds of his first post, im sure he's well aware of how many people think its useless, and how many people try to prove its useless. and also hes got a point, i havent seen anyone on here, nor in any of the posts defiant has listed above, anyone thats actually used one, and had it tested, and seen if there really is ANY gains at all, how little or how small they may be.

also, i could be wrong, but i dont think he was asking everyone if these things worked or not, i think he just asked what you thought about the idea of him experimenting, and to keep flaming comments to yourself?
and... i think only he can be the judge of whats a waste of his time and money.


i wish you the best of luck with this project, and i hope you do gain something from it, whether it be knowledge, or HP

 

[GSGoinFast]

i think its a great idea. test it out, and make sure you dyno before and after, post both dyno sheets. he said he knew that it probably wouldnt work, so hes not going into it expecting amazing things. let him do it and stop being assholes. if he has the money and wants to try it, fine, the results will be useful to future people asking about those things.

 

[nelapse]

First off i know it wont do crap, but humor me. If it does anything i will give you mad props. I am an Aircraft electrician and i know my electricity. The amount you would need for your electric supercharger to work would make your altenator die and your engine would run like crap. You would need more than one battery, and if you have a cone filter it would probably ruin whatever smooth velocity you had. In my opinion, spend your money on something else. I am soon doing a DIY thread plus site just for NA eclipses. Trust me there is better stuff for $150. Your altenator is rated what 75 amps? If you use too much power you lose ponies. my .02

 

[dr1665]

All I will say to this travesty is this (and then I will need a cigarette):

Look at it this way...

Supposing there was another product out there called the Flaming ##########. Suppose this product was a simple, bolt-on 50whp on the average car. Now suppose it cost only $50. I can flat out guarantee you that every NT car in the free world would have one of these installed. (We'd just remove the decals and not mention it to anyone.) This goes to say that it doesn't matter how much shit people talk about these things, whether it be here, 2GNT or any other forum anywhere else on the web. THEY DON'T WORK BECAUSE THEY ARE PHYSICALLY INCAPABLE OF DOING WHAT THEY CLAIM.

Now, if you were Mr High Roller here with money growing on trees in your backyard and even coming out your ass, I'd say go for it. What's $150 to someone who's made of green? BUT YOU SAID SO YOURSELF that you're "poor." Brother, we're all poor. Look around! Turbo or not, we drive DSMs! No one here (with any credibility) wants to see you blow a good deal of money on worthless junk that will do nothing more than fund some fat scammer's pockets in the end.

You came to this site to learn about your car. People here have been gentler than usual with you on this one, but dammit man! Use your brain! Don't waste good money on crap that won't can't do what it claims to do! Laugh this one off all the way to Howell Automotive and get yourself some respectable equipment!

 

[Defiant]

Hrmph. An echo.

 

[boostin1g]

go grab a hair dryer and sum duct tape and shit there you go free diy supercharger



dude dont blow your money on this if you think about it some one some wear has tryed it and if it did work you would know it. if all you here is bad things about it this is why its not like every one has it and isnt telling every cuzz its so great think about it man. read his fed back about them .

 

[ShadowWulf]

THEN, in hindsight, im still gonna do this project BUT i have been thinking (actually the blowdryer idea set me off :laugh: )
What small, yet extremly powerful fan would someone recomend to mimic those seen on e-bay? And not a bilge pump either, im mean something small, yet capable of cranking out alot of air. Reguardless of weather i test an ebay product or one of my own the result is the same, its testing the -principal- of the thing that im curious about.

Any non-inflamatory advice would be helpful. This is a project im seriously interested in, one way or another.

 

[jott5555]

you should check out the e-ram one.. it yeilds results..

[blackGSX2g]

Speaking of hairdryers...I've got a t-25 you can play around with :laugh:

Maybe you could take the exhaust housing off of it and connect the shaft to a powerful high rpm motor. Someone did that awhile back...it had pretty good results but was very expensive.

sorry to pop your cherry but my buddy matt has a 96 240 sx before he put the rb20det in it he had the ka24de with obx headers intake manifold and intake ,pulleys port polished head full 3 in exaust and a venom 400 control unit he pulled 190 at the wheels he bought one of these e boost deals and asked me what thought , its ass i said without missing a beat, he put it on and when he hit the "boost' switch to turn it on his car stalled bogged and ran like crap, i hooked up my logger to his car and sure enough i was right the pos thing couldnt feed enough air into his motor let alone to make a gain but it couldnt even push enough to make his ran run normally, they are a waste i wouldnt spend 25 cents on one, believe me dont buy that crap no lie i have seen someone modify an electric leaf blower with a power inverter paid 100 bucks for everything put a boost gauge on it just to see what would happen i was in the car he hit the switch and the gauge shot up to pulling vac to 8 psi and held there the car pulled hard as hell for what it was,a sunflower sun fart w/e u want to call it. try that it took him about 40 min to rig it up try it,
