Electronic Turbo???

[mcalvo]

Yo guys!.. Me again! Costa Rican guy is back!

One questions for those who maybe had tried this "turbo" before: is it any good? How much hp power increase could I expect. Guys from the official site say I could expect 10 hps at least.

Any opinion would be very appreciated.

Thanks a lot.

Hey Calvo,
Remember a few months back about a product similar to this electric Turbo you are asking about? I will still offer to send you my Girlfriends electric blowdryer, I will even pre-wire it for you. All kidding aside, these items are not worth your time (in my opinion) the electrical system on the Metro is not robust by any means and this "Turbo" is simply a motor with a fan on it that will not do what the advertisers say they will. It just can NOT pump enough air to give a forced induction or blower type aspiration.
I hope this helps

Heya Mik13usa!!

Thanks a lot for your time answer my question man!

Guess you are right.. so i will wait for your gf's dryer then!

Haha.. just trying to get some extra power on my beauty. Any ideas would be appreciated.. really a lot!

Lol, only what that'll make it go faster is by strapping it to the back bumper like a jet engine

Show off man!

LOL Just because you got some gems for your ride doesn't mean I can't attach Mik13usa's gf dryer wherever I want!

Rear bumper is quite good for a hyper propulsion turbine, duh!!

Might be better off with one of these babies!

Just to lay waste to this "theory" on electric turbos....
An article I found on the E-Ram electric supercharger..
Quoted from How to waste money

While the ads touting this product make a very seductive argument for buying and installing this item, the actual performance gain is so small as to be unnoticed. The E-Ram only powers up at WOT (which is when you'd want it to power up). It is supposed to give up to 1 PSIG of boost; unfortunately, it does not deliver.

Before I can rip apart the ridiculous claims made by this product's vendor, I have to explain what is supposed to happen. Consider a 2.5L V-6 with a volumetric efficiency of 82%, and with peak HP at 5850 RPM. We need to find the amount of air, in cubic feet per minute (cfm), that this engine is able to pass at peak HP. Now, the displacement of the 2.5L engine (is 2.5L, but we're going to work with cfm) is 152.4 cubic inches. Using the above mentioned facts, we can figure out how much air the engine is capable of passing.
vfr = (rpm * 0.5 * cid * ve) / 1728
Where:
vfr is the volumetric flow rate of the engine
rpm is the engine RPM where expected maximum power is developed
cid is the cubic inch displacement of the engine
0.5 is a factor that takes into account that an gasoline engine only moves air for two of its four cycles
1728 is the conversion factor from cubic inches to cubic feet

Now, we plug in numbers.
vfr = (5850 * 0.5 * 152.4 * 0.82) / 1728
= 211.5 cfm

From the above formula, we find that the 2.5L V-6 is able to pass a maximum of 212 cfm at WOT. Now, the E-Ram is supposed to provide a 1 psid boost at WOT, which would be 212 cfm for the V-6. To provide this much boost for this flow rate of air, one must expend about 1 HP, or about 746 watts (W). Taking this into consideration, and assuming for the moment that the E-Ram is able to provide this boost without any mechanical or electrical losses whatsoever, the E-Ram should draw (746 W)/(13 V) = 57.4 A (amps) when it is running. However, under test, this item only draws 15.3 A, for a power draw of 199 W (0.27 HP). So, at most, the E-Ram can provide about 1/4 psig of boost, which is hardly enough to offset the HP loss just by running this thing.

To compound the situation, the E-Ram actually provides a intake restriction when it's turned off (during any part-throttle response). This, in turn, requires the engine to work harder just to draw air in, which is power that could have been used instead to propel the car forward.

And just think, your metro's alternator is capable of about 50a PEAK to the entire electrical system. No power, plus it will destroy your alternator really fast.
