Electric super charger...don't flame please!!
 

I saw this in Euro Tuner as one of their highlight performance parts...I know - I know - the 'turbonator' is fake, but I've never seen it in a reveiw section of a car magazine.

"This configuration still produces 3.0 lbs. of thrust at 800cfm, "
800 CFM = 22653 L/min

3.5L @ 7,000 RPM = 12,250 L/min*
*assuming 1 atm of air entering engine
...so at least the #'s sorta work out...

Please don't :icon20: me for posting this - I've read amd laughed at others posts about 'turbonator' type devices from ebay, but this website at least seems decent.

In the end, I doubt I'd spend $300 for this, but I think it could work...thoughts?

:icon18: :icon17: :icon18: :icon18: :icon18: :icon18:

You asked for it!

:ugh2:

If you like that I've got two hair dryers tapped together at like half the price of that junk I'd be willing to sell you. :icon22:

Look. I'm thinking(hoping) you have more common sense than the average idiot newbe suffering from acute brain damage:icon14: . Please tell me you're joking right? :rolleyes:

:icon18: :icon18: I know..... This is some really funny joke to get everyones panties in a bunch. Right? :icon43: TELL US YOU"RE JOKING!!! :icon20:

:icon22: I have a feeling you're not joking and this ain't funny and all your "cool points":cool: are lost forever. :icon22:

say it aint so. :icon43:

you have got to be sh!tting me.

DO IT!! and obviously the more of them you buy, the faster your car will go...


right!!??? haha

Have you not seen the dozens of threads dedicated to this nonsence???

come on guys - the guy was being serious in his post - cut him some slack =

electric superchargers are nothing new - they just are not very effecient and they put a huge drain on your electrical system

no i got this and it gave me 19.5 rwhp...thinking of getting a dual set-up

uhhhh the SS American had giant electric fans that blew air into her boilers.

Basically an electric super charger.


They used electric because rather than have to run a huge pully system up to the top side, the used electric cables... not as efficient but worked. The SS America has the transatlantic passenger vessel speed record.

first350 (Peter) is a good guy and he did say that he expected some heat. Just a question and he does say that he has laughed at the turbonator etc..

The physics behind this will theoretically work. Will it pass the field test? Maybe. If you were to go for it I'd install it as close to the engine as possible. I'm not sure if the computer will be able to immediately compensate for A/F ratios.

well i think you guys are wrong with the electric supercharger concept. there are ones that really work giving you a good boost. the only problems you need to upgrade the alternator to charge faster the 2 batteries for the supercharger. you want more info on this? contact thomas knight. The only problem is the kit runs for about 1500 bucks.

Well I actually went to the site and guess what: they are quite honest and straightforward about their product. No BS HP gains, a normal dynochart, info on power consumption, Flow bench test when not in operation, taking into account losses, stuff like that...

OUCH

Should be ok for 12% more power according to those numbers, but they claim 9. Like 20HP on a 350Z, if it really works. But at 600$ (!!!).... You can get NOS for that money, right?

thanks Walt! The only reason I even looked at their website was b/c I was so shocked that it was in the 'Euro Turner' magazine in their products section...it wasn't an advertisement, but a short spot light done by Euro Turner.

The #'s they post on their website actually make sense (I've worked with electric fans before on a few engineering projects)...in the end, don't worry, I won't be buying one. If I have $600 to spend, I'd rather stretch a little more and get a Utec.

-Peter

I read that in Euro-Tuner too, they said you get 1psi gain from one unit at $300 or 1.7psi with the Dual one at $600.

Why dont you buy it and Dyno it. If it puts out a real 1.7psi for $600 I will be amazed.

An electric super charger, if designed well, is not as lame as you might first think.

I don't know which one you're reffering to though, I didn't bother with the link.

An electric super charger does not use any HP to make HP like a belt driven blower and also there is no restriction (resistance) in the exhaust perhaps like with a turbo.

Also with the electric super charger wired to the throttle, with a positioning sensor, you could dial it in, to have no lag like you might with a turbo.

Or you could have it wired to only come on when you want it to, like WOT.

I wouldn't use one on a Z, unless I designed it myself LOL, like I have time and the electrical background to make a prototype. Though it's actaulluy extremly basic in design. and wouldn't be much harder to install than a Pop Charger and stereo minus the speakers and wiring.

I actually thought about if it was possible to make an electric supercharger that can have put out like 9lbs of boost and up. About 2 years later I saw a commercial on TV for one. There's was nothing like what I had in mind. there's was cheap.


I also have an idea for an eletric powered car that if my idea worked, you could drive it across the U.S. and back non stop and it doesn't use any solor power. I have yet to see anybody ever use what I have in mind. Maybe I should get to the drawing board before somebody steal that one too:mad:

^^^^ Yeah, let us know how that car comes out. I doubt there would be any demand for an electric car that can cross the country w/o solar, so take your time - no rush. Did I tell you about my idea for a machine that if it worked would turn copper into gold?

A leaf blower will work better :)

I used a process flow design program to model a 9psi compressor.

At 80% adiabatic efficiency and 12250L/min under ideal gas conditions, it looks like the compressor will draw 13 kW of power from the battery (that sounds like a lot to me.) This is equivalent to about 17.6 horsepower, which is what it would leech from the engine if you were using a pulley.

The intake temperature will go from ~25 degrees C to 80 degrees C. (Can you say INTERCOOLER?)

This program requires mass flow or molar flow, I can't just input L/m. The conversion I used was PV=nRT and I got 497mol air/min at 300K and atmospheric pressure. This translates to 32 lb/min air so that sounds reasonable, on par with most turbo systems at 9psi.

If you want me to run any more simulations let me know. I can change inlet and outlet pressure, inlet temperature, molar flow rate, adiabatic efficiency, etc.



----------------------------------

Next:

3 psi compressor...
45 degrees C outlet
6.5 horsepower
4.9 kW


P.S. Hopefully the 80 degrees C will keep anyone from thinking that 9psi inline compressor on the air intake tube with no intercooler is a GOOD idea. On that same note, the 45 degrees C from the 3psi blower sounds pretty stupid to me too.
