18-22% better MPG for £98!!!!!!
Has anybody come across c-tech 3000??
c-tech 3000
They tested this in the December issue of Banzai on a Honda Civic and although they didn't get the 18-22% improvement claimed they did get 4.6%. I think the claims are outragous, 18-22% improvement?...no chance!!!
Anybody used this??

Nope, most dont fall for these devices that give fuel improvement, you can save 15% by not flooring it everywhere, much easier and cheaper but you loose the smile

We'd all love to believe, but I think the overall view of unburnt fuel in the engine is deeply flawed. There is a very good website here which has details about products such as these. Interesting to note that a similar platinum based product called PVI was fined $75000 in the States (and lost the subsequent appeal) for making false claims about improved fuel economy.

The name of the Dr checks out though. He is at leeds doing research into Uranium Dioxide (which is something we have a lot of at work 
)
However the research seemed to be centered on introducing catalyists into the combustion process to reduce the levels of NOx and CO. Oxidising these will yield a little more energy but I can't see it giving 10% more.
I've got his Email address and might see if he can illuminate us all further.

Well, I got a reply from the professor at Leeds university.
I expected a negative response to the claims I must admit. Still seems odd that it sucks in the maximum amount of gunk when the throttle is closed.
If these systems were to work then surely they should inject in proportion to the engine load, this system would work backwards !
Sorry for the delay in replying.
Basically the system is equivalent to having the components of the
conventional catalytic converter in the flame of the engine. Thus
unburned hydrocarbons are essentially eliminated (by being usefully
burned IN the engine), and CO levels are reduced, as well as NOx
levels. The combustion process is thus more complete, and the energy
therefrom is where it is wanted, pushing the pistons. The improvement
in performance is thus largely dependent upon the age and condition of
the engine, but 10% is not uncommon. If you take advantage of the
improved performance by accelerating harder to enjoy the
"rejuvenisation" you won't get the improved mpg you would get if you
continued your previous driving style!
Hope that this is helpful

If you want over 20% better fuel economy guaranteed, for £98, buy a tatty old 950cc fiesta. 
Serious question though - it appears to talk about bubbling through an 8 thou hole due to vacuum. There appears to be a slight flaw in that when applied to a turbocharged engine that is developing boost?

I notice that all the press articles are not independent tests carried out by the publishers and a more like press releases from C-Tech.
It's a nicely designed website with some convincing arguments for those who are easily misled

Trouble is, nowadays, Uni's are not independant, the departments can do private research into what they want. Indeed many are run as private companies within the campus
The daft thing is, I can see that introducing catalytic compounds into the fuel/air mix would encourage the reaction of CO and NOx and thus reduce emissions but not give any measurable energy release. HOWEVER, the design of this kit is such that it only draws in these compounds when the throttle is closed, on a turbo car you would not get ANY drawn in on boost.
