Seen this on ebay, intriguing concept.

Will it work?

I'm not really that sure.

Looking at the product, it resembles a model aeroplane ducted fan engine connected to some silicone tubing with a filter on the end.

I'd prefer to have a good look at one before I was going to even consider attaching to an engine.

That's exactly what I thought smile

I posted this same Topic on the TVRCC site and someone came up with this link here kinda confirms my suspicions that they wouldn't be much use. hehe

I love the term 'compressed molecule technology'!

Sounds convincing! I'm sure there will be some lad with a 1.0 Saxo willing to give it a go.

From what i remember, the electrical draw from the engine (which ultimately uses a bit of power) more than matches the potential gains..

I think this is a good example of 'Too good to be true' and it is....

It most definitely will NOT work. The problem with this kind of thing is that to many it might seem plausable because the concept sounds similar to turbo / supercharging.

If you look at the power required to drive a real turbo or supercharger its immediatly apparent that:

1. You would need a *big* electric motor to drive it.
2. This would draw serious current requiring...
3. Hugely oversize alternator, wiring, batteries etc etc.

Such a thing could be built, but because of the points above its way better to take the energy required directly via exhaust (turbo) or mechanical drive (SC).

Basically the only thing this product does is increase the chances of bits breaking off, falling into your engine, and destroying it.

Um how you going to drive it? Oh electrically with power from the engine, so your drawing power from the engine to alter the fuel air mix. I think you would have more joy just cutting an air scoop in your bonnet.

my workshop lad has one of these on his 1.4 16v clio,
I must admit it does seem to make a noticable difference,on his car!
but when I tried it on our voyager {3.3) it did nothing.
it obviously works (better?)on small capacity engines.

On smaller engines I've seen reports where they achieve 1-2psi of boost so a small power gain can be had, but they don't have the airflow for anything with a decently sized lump

Even if they did, how the hell is the ECU going to provide the extra fuel when it was never originally mapped for positive pressure? confused

The OEM calibrators didn't map the fuelling as an open ended line just in case someone decides to one day stick something like this on!

In the event of going from N/A to turbo/supercharged a number of changes need to come about; and apart from the obvious mechanical ones to lower compression, etc, the most important is to completely change the engine management system to one that can cope with and correctly fuel such an engine.

All this b*llocks......

Ad for the dim-witted said:
...This provides a low cost but effective alternative to expensive and difficult turbo/supercharger conversions on naturally aspirated cars as the ECU or the MAS or MAP reads the difference in pressure...

...Thousands of pounds and hundreds of hours of R&D have gone into creating the ETS Supercharger to utilize what we call Compressed Molecule Technology Or CMT...


...To cool air effectively you need to do two simple things: compress it and move it...

...The air molecules are drawn into the fan at such speed that they are fractured and compressed, making the air denser and allowing more flow into the same area – a three way air cooling process...
...is ill-concieved nonsense that sadly rings a bell in the dead heads of the Chav generation rolleyes

Hopefully no-one with an iota of common sense who actually cares about their P&J would waste money on such crap.....

Compressed Molecule Technology, hey that sounds really sophisticated, anyone inventing jargon like that is bound to know what they're talking about! rofl

Thing is in the fullness of time we should see a electric supercharger, Ford / visteon produced one which was using a pretty high spec motor and was a study into using it instead of capacity to increase power.

It was successful in terms of power improvement but the overall energy efficiency wasn't there, so it hasn't been adopted.
Wait until they shift to 42V then it'll probably re-surface

the report is here

I would have thought an electrically assisted turbo made more sense, using a short term electrical boost to overcome lag.

Thats in work too wink

Mind you turbos and our cars aren't the happiest of bedfellows...

How's your S Pete? is it all in one bit again?
