Liberator Fuel Saver
 

liberatorfuelsaver.com

It saddens me to watch a Nascar driver endorse a product that does little to nothing to improve mpg. The extraordinary claims make it unbelievable. Question is, why don't they work?

FWIW I searched for Liberator and got no results on the site. They claim it is different than the Tornado.

Maybe he really doesn't know it's BS?
Much more likely the money is more important that any integrity he might have had...

oooo a SWUMBLE that pushes air into the engine. So you put this thing into the intake tract somewhere and it says it will increase the velocity of the air coming in?

So to increase the velocity of a fixed volume of air we add some restriction (the turbulence or "swumble" this gizmo causes) Bernoulli's principle tells us what happens when air travels over/around/through a restriction we get a velocity increase and a pressure reduction.

Same volume or air coming in through a restriction is not going to be as easy for the higher pressure ambent air to push into the engine. so the engine will be "sucking" against the drag of the restriction. Good news is that to make up for this restriction we can just open the throttle a bit more and the engine will just squirt the right amount of fuel anyway.

Another bit of luck for this thing is the little SWUMBLE makers look small, so it wont do much and what little it does do will be undone by intake valves and that bit of the intake tract down the line from this thing.

At least it has a slight chance of being better than the tornado. Why do I say this since it is placed after the Throttle Body (TB) so it will not have the MAF screen and throttle plate to clean the air flow. Also if installed before the MAF it might not see all the air and mess up the fueling.

To think instead of installing a larger ported TB to help remove a restriction and increase VE (volumetric efficiency) I should have just plugged the intake to create a restriction.

If anyone would want this tested out you can order me one and I can post raw MAF, fuel trims, and almost any other data you would want. All you have to do is pay shipping since the posted price for a 2003 Pontiac Grand Prix is $0.

calculated load and VE
 

This won't do much on port injection as factory do a lot of engineering on intake manifold for even distribution .
It probably would help on TB systems to distribute fuel in the manifold better. Just like they use heaters on some to atomize the fuel droplets .

not really sure it is gonna help on tbi, at least not enough to use a word like "probably".

Well, didn't say how much it would help .

TB systems have big problem of puddling, just like carb manifolds so here it should help some as its a wet system unlike port injection which is dry and can be optimized much easier for even A/F across cylinders .

Emailed Company To Test out Product
 

Hey guys, I actually just emailed the company and they are shipping me one for free so I can test it out. I have an ultragauge set up so I can see if there really is a difference. My best mpg to date is 29mpg. So you will have a completely unbiased test coming up soon.

...selling your soul to the Devil? Money has a way of doing that.

(do I hear Charlie Daniels playing "Devil Went Down to Georgia" in the background?)

not sold taking advantage of being a poor college student and milking it

Beginning of spring is a bad time to install any device claiming to improve FE. With warmer temperatures and the end of winter blend gas you'll likely see FE improve over the next few weeks without doing anything. Will be watching for your results.

Well, I found the website: Liberator Fuel Saver - Save gas and fuel for diesel, cars, semi-trucks, suvs, trucks and more! Gain more miles per gallon (MPG)

I have a hard time believing that somebody with a Hummer going from 10.5 to 14 mpg with this gizmo?? A 33% fuel economy increase? Where's the flux capacitor?
I'm able to match the 3.5mpg increase with my truck, but only if it looks like a MadMax reject with all the black plastic aero panels I strapped to it.

I'm in the middle of testing the Volo chip right now so I won't install the liberator thing yet, I also got some vortex generator fins in I want to install but I think I will wait till this tank of gas is finished so I can see the affects of the volo chip FS3. I'm a little hesitant to open up my throttle body because I've never done any type of work in my car. heck I had to google just to figure out where it was under my hood.

havn't had a chance of installing this yet but not really dying to since I'm pretty sure we all know the outcome, good thing is I got it for free.

I've noticed that, too. http://ecomodder.com/forum/fe-graphs/graph2691.gif

I dunno...

That part on the right-hand side did a pretty dramatic jump upward. Each bar is between 3 and 4 days worth of driving.

It will Liberate the money from your pocket to his pocket.
The Liberator, catchy name, sounds like a name of a gun or a costumed Superhero.
