Improving fuel economy

My beetle still has a device inserted in the air intake to the carbi to make the air swirl, mix the fuel better and thus improve fuel economy.
I know that it works - drove over 1,200km week to and from work (Melb - Castlemaine) so could really tell the difference in consumption before and after!
Didn't think it would be possible with EFI, however have just seen this on e-bay.

Seems to be the same principle, has anyone else used / know of them?
As a '$25 decision' I think I can afford to risk it.:poke:
 
I tried a Hi-clone, which appears to be the same thing, many years ago. I took records of driving before and after install for a month.

Near the end of the 30 guarantee, I took it out and got my money back. I found it made no noticable difference to power or torque, and only about 0.5%-1% differende to the economy. Nothing near the 10%+ they claimed.

In theory they shouldn't work, because any swirling they do would be interrupted by the throttle butterfly. But having said that, my old Falcon had something very similar, and when I briefly removed it, the car used more fuel.

Hi-clone is what I have in the 67 beetle. (Had forgotten the brand.)
My experience was similar to that of GOD with (her?:biggrin:) Ford.

Will take Beigewagon's comments as a caution - as I thought it sould work best with the older (carbie) engine.

Will be an interesting comparison, I guess.;)
 
do some research into the source of these things - from memory the shonkster who marketed these is a convicted conman many times over. There was a 4 corners (or similar) on him in the past 12 months. Its an absolute gimic - any apparent improved fuel economy some may account I would suggest is incidental. There are so many proven methods to improve your air flow, power etc and subsequently fuel economy...

Ill have a look for the story on this
 
I used a device that you filled with distilled H2O, put in a bit of lye, wired it to your battery and piped the resulting gas into the intake downstream from the mass air sensor.
This theoretically created a hydrogen rich fuel load which burns more explosively and cooler than gas.
The Problem: with more O2 in the mix, the car's O2 sensor read the exhaust as burning to lean. The result was 1-2 mpg less but a lot more perceived power through he whole range.
Apparently I need a $100 electronic gizmo to bypass my O2 sensors or a much more expensive aftermarket engine management system. That way I can tweak air/fuel mix Currently I get 28 mpg on Oregon's crappy 10% ethanol blend, so I guess I can't complain , but I do anyway
 
a performance chip for $10 for + 60 HP :eek::huh:

:monkeydance::rotfl:


this 'company' even have a GMail account as their contact hahaha

how do you say....SCAM

I've improved my fuel economy by increasing the engine capacity! I kid you not!!

The old EA82 used to do 400km max to over 50 litres. The EJ22 has so far pulled 400km to 41L and has done so since I've had it in. Three tanks so far filled and they've all pulled up a little bit over 10L/100km with a boot load more power and torque! Love it and will not be looking back at the EA82...

These "swirl" things do nothing!
They even suggest them for turbos - with it going before the turbo and intercooler.

Seriously - if they worked why dont the car manufacturers use them?
Answer is - they do. Subaru puts something similar in the engine - they have tumble generator valves at the last possible spot. Even these are more about reducing emissions at cold start.

thats improved tech or ya. just like modern day diesels. as for hiclones SNAKE OIL. i have thought about puting a hi flow powered fan, forcing air into the intake. thus creating a bigger air to fuel mixture?? the only reason i haven't had a go is that it sounds to easy. someone must have tried it before. like a try hard turbo. what do you rekon? any thoughts? it seems to make sense to me, BUT????

well a turbo IS a fan..
oh you mean an electric fan.........sure it'll work


you just need the right electric fan......:lildevil:

i'll leave as an exercise as how to mount it


oh don't forget 1kw power source for the sucker

I had thought about hooking up a 2 stroke leaf blower to the intake of one of the paddock bombs - attach the 2 stroke throttle to the throttle of the paddock bomb's motor... The thing that stopped me was the fact that we didn't have a leaf blower and a decent new one was about $500+

If you used an electric fan you'd need a rather big one so it doesn't become a drag on the motor...
