Air Charger Versus SuperCharger

[Normal_aspirated]

u mean these......

Bro,

 

Be it the real electric SC or TC, PSI and Bars are just numbers.

 

TD04 running at 1 Bar is totally different with a VF22 running at 1 bar.

 

If TD04 and VF22 running at 1 bar is the same thing, Garrett will be manufacturing Ice cream and HKS will be selling women's apparel.

Yes, and these electric SC are really capable of boosting up from 5-20 psi pressure, unlike those ADM`s aka aircharger cant even get close 0.5 psi in real life. These ESC( electric supercahrger ) are alike those real life superchargers widly used in the U.S( brands like Vortech, ATI Procharger, Powerdyne, etc. ) which utilised the centrifugal compressor to run them, but of course power sourse from the crank pulley. The ESC runs on a single 8HP electric motor @ 24 Vdc for low 5-6 psi boost, or even triple 6HP motors @ 36 Vdc( around 20 psi ).

In fact ESC is already in the market for quite some time already, mainly as a secondly turbocharger( Turbodyne aka Turbopac ) for those big trucks during it`s initial pickup to counter turbo lag in turbocharged engines. It in which activates only during low rpm`s, as the turbo will take over after that. Garrett also venturing one too, called E-Garrett. For HKS, I dont think so, as their market share in turbochargers still considering peanuts for production vehicles.

In force induction, arent we looking for boost? These numbers above will represent what it`s capable of, else can forget them...go get the real SC/TC.

 

My 2 cents.

Like I said those numbers looks nice.

 

Like I once again stress that a TD04 and a VF22 running on 1 bar. The VF22 would be significantly quicker even while both turbos are running at the same boost levels.

 

Why ? For eg.

 

TD04 13C turbos is capable of 360 cfm.

 

TD05 16G is capable of 505 cfm.

 

If you are trying to tell me the TD 05 is slower than TD04 even when both are running 1 bar, than you've gotta do some serious research.

 

Like I said, the psi and bar figures looks nice. But I don't think it'll out perform the genuine ones. If the above brands you mentioned has been in the market long enough, than theres something wrong with their products or marketing techniques because certainly none of their products have been used in any famous motorsport racing.

 

If they are really that good, how come there isn't any talks about how big the exhaust and compressor housings are ? how many cfm is it capable of ? I can run a TD04 at 20psi as well but it'll probably die after 5 1/4 mile runs.

 

As for E garrett, I've never heard of it. Maybe you can provide an article on that as I would love to read.

I`m comparing the ESC with the ADM aircharger, not with the real turbo`s & i know what you meant in the numbers my friend... And i`m not saying these ESC are really that darn good, but had gathered some informations on the net regards them with some good comments regards this particular serious invention in ESC world thou. Maybe you ought to do some research too...

 

As you can see in the attachments, the impeller is quite huge in it`s size ( 120mm OD ). It only spins at 25k rpm to create enough cfm for a given engine at an instance depending on it`s size during throttle at wide open, & thus also create boost at diff levels @ around 15 secs intermittent( depending on battery capacity ). It`s sort of like NOS system, gotta recharged, but it`s free.

 

The bottom 2 attachments is the turbopac i mentioned( U.S made ). It`s simply a pice of art i would say in technical terms, as it utilised a 12-24VDC, 3-phase sensored brushless motor to turn it`s impeller @ 45k rpm. But it`s a pity they got themself into financial crisis, partly taken over by Honeywell then but dont know about now...

 

As for the E-Garrett, i can only show you this:

IMHO if this ESC really work it makes a pretty good option for street driving and is worth considering.

[Redspring]

Any one know how this staff work?

Does this charger start once you start the engine or it run only when it reach a set speed?

It looks simple to install but have never see any car that install with this before is it commently use?

[Casey]

supercharge increase ur fc???

[Jusjazz]

It works only during at WOT, by means of a limit switch attached around the throttle linkage... same as would be in a NOS system.

 

This comes fm the states, thus not commonly used, and also not very popular over there cos of it`s complex design in installation which makes it too pricy... but definately has more kick than those Aircharger aka axial fans used here which is less or not efficient at all.

[Redspring]

The E200 came with "Kopressso", does this mean one of this super charge unit in there?

[Jusjazz]

Nope, it came with the real belt driven supercharger, 7 if i`m not wrong it`s Eaton brand roots type...

[Jusjazz]

If your MAP sensors can work along with the increase density of the chargedd air, what do you think? More Air+ More Fuel = More Power!

[Casey]

more fuel then its not good...

 

but may i ask will adding a supercharger add strain to my stock engine??? as in reduce its lifespan. Anyone here?

[Intx]

It does if it does not boost.

My car is more economical for a highway run not for the city
