Hello, I wondered if any of you are running one of these: http://www.ecotekplc.com/CB-26P.htm I've run one in my last car and noticed the difference in accelerating and a small difference in fuel consumption (I was getting about 10-15 miles per tank more) this was a fuel injection car though. I thought it would be suitable for my 1600 TP with the standard inefficient manifold. There is a problem though, below are the fitting instructions and I can't see a suitable place to install. Any ideas? I'm running a standard Solex PICT 34. http://www.ecotekplc.com/CB-26P.htm.
I wouldn't bother, mate. There are loads of these nutty fuel saver things around, and most do absolutely nothing. You'll notice nowhere does it accurately describe what the thing does...
I thought this too to start with. Perhaps you should read the website as it has been tested independently, the report is downloadable. I used one and throttle response is noticeable. I draw the line at fuel magnets though they are load of rubbish.
If it worked it'd be fitted as standard to all cars. Hocus Pocus. Funny how you can convince yourself something works when you've paid for it.
And paid 50 quid for it... The more expensive it is, the more reluctant folk are to believe it doesn't work. Have a google for eco tek reviews. It doesn't look good....
The throttle response is noticeable, I've run one. Fuel economy savings weren't great but I was running a injection car so I don't think there was much of gain to be had there. It was installed after the air mass meter so the ECU couldn't detect it. Think I've found a way of installing it: http://www.cleanburn.co.uk/mini.htm.
They sound like someone slurping a milkshake when they operate So much so people keep telling you there is somthing wrong with your car lol
Manufacturers are starting to fit these kind of devices: http://en.wikipedia.org/wiki/Mercedes-Benz_M272_engine Variable Valve Timing and Tumble Flaps Improve Fuel Efficiency Valve timing is automatically adjusted by electro-hydraulic vane-type adjusters on the end of each camshaft. At partial throttle, the adjusters keep the exhaust valves open as the intake valves are opening, using this valve overlap for internal exhaust gas recirculation, reducing exhaust emissions and improving fuel economy. Approaching full throttle, the camshaft adjustment optimizes valve timing for maximum power. Tumble flaps in the intake passages near the combustion chamber pivot open under partial load, improving combustion by creating additional turbulence around the intake valve and in the combustion chamber. During higher engine loads such as full throttle, the tumble flaps are completely recessed in the wall of the intake manifold. While better combustion helps improve engine torque, the primary purpose of the tumble flaps is to further increase fuel economy, and tests show that the tumble flaps indeed boost gas mileage by nearly two percent. While variable valve timing gets a lot of credit for the engine’s unusually broad torque curve, a two-stage magnesium intake manifold plays a key role as well. Below engine speeds of 3,500 rpm a set of flaps in the manifold close off short intake passages, forcing intake air to take a much longer route into the engine. This creates pressure waves that help the intake process and improve torque. At higher engine speeds the flaps open and intake air flows the shortest distance to the combustion chambers, helping to make more horsepower.

The tests and results are flawed as they are carried out on the track, not on a test bench. In the real world environment it is impossible to repeat the test per/post fitment/use of the aftermarket product. Note that this is not endorsed by any car manufacturers... Did any of you read the reviews recently for things like redex/powerboost etc? Of all the products tested one managed to achieve identical results. Each of the others actually DECREASED power output and reduced mpg. It's easy to put something in or on your car then jump in and think you can feel the difference. The reality is that most are placebos... A bit like night nurse
There was quite a nasty thread about these on JK last year I think and it got quite heated....partly why I left the site as people were being really vindictive.
Well I just ordered a SVDA dissy instead. It's supposed to give 3-5 mpg more over my 009 dissy. As the Eco Tek valve breaks the vacuum in the manifold under load I'm thinking it may do more harm than good to fit one as it may interfere with the vacuum advance. Also the only way to fit one would be to drill into the manifold or fit a spacer between the carb and manifold. Don't fancy the manifold route and the spacers I've seen aren't thick enough so case closed.
Flat 4 engines are not efficient. Alfa Romeo dropped theirs because they couldn't get the emissions down. A sad day for me as it was the only part of the Alfasud that lived on Subaru have managed I must assume but I've not seen the mpg figures. Drive economically. Plan for the road ahead. Keep it serviced and maintained. All these things combined "could" add a few miles but how far do you actually go?? For this gadget it might work in modern cars with electronic stuff and variable timing etc etc but not on 1940's designed engineering. Years ago I fitted energy tyres and better spark plugs to my 954cc Citroën Visa that were supposed to improve mpg. On that 70's designed asthmatic engine it made no difference. Short journeys are a killer of gas. My bus will drop its fuel like a loon on short trips like town driving hene why I don't use it anymore unless I'm going away. However at the end of the day it's your money so go for what ever it is you choose and post keep us updated. TLB has an enviable product review section so post a review tonelp others.
Sorry, wasn't suggesting TLB had gone that way! I think it was the organic chemist thread! ;D ( it was quite entertaining to start!) I fell for the brockett thing with the loss of lead in petrol with my old van, only thing it did was get tangled with the fuel sender so i had amazing mpg until I ran out of fuel!! I agree though love TLB and all people here amazingly helpful, great tech help and resto bit brilliant (Esp diddymen + Zed!) Interesting gunnargav had let throttle response improved with this though, placebo? I would be really interested to see if it works on a bay though. Certainly worth a try. I think a well serviced engine with well set up twin carbs is probably the best way to improve this though...unlike mine! : Keep it up guys Ben
The throttle pick up is noticeable but as said in my last post I'm worried it may mess up the vacuum advance. All the other vehicles I've seen it fitted to don't have vacuum advance. I'm going to try some other more standard upgrades first like fitting a SVDA dissy, Putting back the airbox in with a K&N filter. I also heard from aircooled.net that changing your gearbox fluid to fully synthetic will help with MPG, so I've changed mine. Glad I did, the stuff I pulled out of my box wasn't nice!
