Fitch fuel Catalyst- Fact or Fiction ?

**TommyD** · 04-04-2008, 07:49 PM

So, one saturday afternoon I was watching 'Horespower TV' like I usually do and they had a dyno test of the Fitch Fuel Catalyst.

After the Dyno tests were done this is what they came up with,
octane HP Ft/Lbs gal/hour
without The Fitch 93 424 490 20.26
with the Fitch 93 426 493 19.70

without the Fitch 89 417 484 23.03
with the Fitch 89 417 484 20.59

This seems to show that with the Fitch installed you require less gas to produce the same Horsepower and Torque.
It would also seem to indicate that you should be able to use gas with lower octane with no adverse effects ( they should have compared 93 octane to 91).
Because I can only get 91 octane here, I was hoping that with the fitch I could use 89 octane and maybe save some money.

So to make a long story short, I purchased a Fitch Fuel Catalyst and have installed it on my charger.
I have kept detailed records of my fuel consumption over the last year and will see what happens with the fitch installed.
I will post back here in 2 weeks with the results.

I, for one, will be waiting with an open mind - I'd like to see your results and I'm not one of the 'If dodge didn't put it on the car it must suck' crowd...

I was toutng the Fitch unit for a few months before the Horsepower TV test first aired. The "catalyst process" in this application makes sense to me, I have seen it work well in other similar appliactions.
A few members at some of the orther forums are running it with good results.
You can also see the Horsepower TV test here.

Go to the "How does it work" link on this site a nice video:

satfrat has been running one for over 6 months.
Maybe he will sing in.

425 hp at 20 gph is very efficient. A typical 425 hp diesel engine will burn 17-20 gph. A 320 hp 350 chevy marine engine that I owned would burn 35 gph. It was carbed not EFI though. If you can run 87 or 89 and get 93 octane performance, thats decent.

Well after running thru 2 tanks of 91 octane my mileage has decreased.
Before the fitch I was getting 17/18 mpg (US) on a mixed drive (50% hwy 50% city)
After the fitch I got 17.7 mpg on the first tank and 16.4 mpg on the second tank.
Same gas station same 91 octane. The only conclusion I can come up with for now is that the 91octane isnt really 91 but maybe closer to 89 as it takes more lower octane gas to get the same HP.

I have just purchased a Diablo predator in the mean time and will start some data logging to see if there is any knock retard present when using this 91 octane.
More results will follow.

There is another member on the forums here that bought one and was going to let us know how it worked, i don't remember if he did or not yet.
Here's alink to that thread
Fitch Fuel Catalyst: anyone using this?

Absolute BS.

Well it turns out I had got some bad gas from the service station. I finally got the diablo so did some logging and found I was getting a s**t load of st & lt knock retard. I put in a can of octane boost which got rid of the LT knk retard but I was still getting some ST.
I have since given up getting my gas from this service station and have switched to shell vpower 91 octane.
After installing the 91cai tune I took the car out for an extended road trip of 275kms using vpower 91octane and the diablo 91 octane CAI tune.
I was very surprised to find I got 23.7mpg (28.4mpg canadian) going 66mph (106 kmh). I set the cruise so the motor was turning 2100rpm.
All I can say is that the fitch catalyst & the diablo tune have shown some definite improvements in fuel economy. Before the fitch & diablo the most I could get was 18mpg.

I get better than that with the Diablo and no Fitch catalyst.

Maybe the 5.7 with MDS, but not the 6.1 which I have.

**Mag Dr** · 05-10-2008, 10:02 AM

Very true, but know idea of what you have, not in a sig or your post.

Anybody try those copper bracelets for arthritis?? I heard you can get a big boost by stringing them across your radiator.

Threads like this convince me the avg American is a twit operating at a sub Jr High School level.

Ya and you probably think the world is flat, man never set foot on the moon and airplanes are really too heavy to get off the ground.
Before you criticize maybe you should do your own real life test so you have some basis to base your comments on.
I was skeptical at first, so I bought the fitch and am testing it.
I dont know how much the increase in mpg is directly related to the fitch and how much to the diablo.
The next test will be to put the original tune back in and do another test.
