Some maybe familiar with what a "Fuel Catalyst" is, for those that aren't I have attached a link below or just do a google search....

I guess these are one of those "sceptical/gimmick" products that claims to do a number of things:

The benefits include:-

-Reduced fuel comsuption

-More power

-Reduced exhaust emissions (HC & CO)

-One treatment lasts for 400,000 kms

-Simply fitted and requires no maintenance

-Easier starting and smoother running

-Suitable for use with catalytic converters

-Keep engine oil cleaner

-Eliminates engine 'coking'

-Quickly pays for itself

-Allows the safe use of unleaded petrol in all petrol engines.

Basically there are 2 types;

a) Inline - which is placed along the fuel lines, before or after the fuel filter.

B) Intank - metal balls that sit inside the fuel tank.

The Particular units we'll be testing are the Broquet Intank & Inline units & Algae-X products. AlgaeX is a little different where it uses magnetics, and is more common on Diesel & Marine equipment, it has a similar effect, but is also claimed to "Condition" the fuel system including injectors, tank etc etc. So we asume this will be more a long term rather than immediate effect.

The test is planned for this Saturday, and will be done at ICE Performance on their dyno. I'll keep you'll updated.

You should get a camera crew and sell it to today tonight or something.

At least get the story to pay for itself

Yeh.. good idea!! I doubt it though.

I still got to fork out $$ for the Dyno time. I know these have been covered before on ACA & TT, but nothing like seeing it for yourself.

dont they need to be run in so to speak. Ie at least 500kms before they start to work. So if u do a back to back dyno it will prolly show nothin, even thou they prolly dont work?

Yes & No! Both products have an immediate effect, but the AlgaeX has an additional product a liquid based "Fuel Catalyst" which is added to the tank, this takes around 2-3 fills to see any results.

I'll be interested to hear the results because the marketing & salespeople give me a really bad vibe about these products.

I think you will find that the manufacturers will do their best to distance your tests from their product if the results arn't positive. They will however ignore any inconsistancies in the testing if the results are good.

One manufacturer has a written statement that the type of test you are conducting (ie short term dyno tests) will not produce reliable results.

browny, it's going to hard for "Broquet" at least to distance themselves, as they will be present and participate in the run. The reason we are doing this, is because I was given a smaller unit to try about 3weeks ago, and found it to be slightly positive only by the "hard to prove"seat of your paints feel. It seemed to have reduced knocking which I monitored via the Apexi Power FC Hand Controller, response felt a little better, and ICE had the car on the dyno last week, where they found the AF Ratio's to be richer in the midrange. The problem with the current unit is we think it is restricting fuel flow and looking at the larger units or the intank units.

So far... it seems "OK" the claim of saving fuel???well I still get around 300Km out of a tank, so I can't say it helps with saving fuel. Broquet have been very helpful and stand by their claims on what this product can do. I guess we will see on tomorrow.

Allright... we did a some runs tonight on ICE's dyno. And sure there were a few "ok! maybe alot" of laughs about these "Stealth B52 Uranium Bombers"..and with possibly goods reason. It was best to be sure and dyno the units, than assume the hard to prove "seat of your pants feel"..

We tested all the units within a 2-3hour period tonight, doing around 4-5 runs per test with about 15-25minutes between each procedure, nigel was also wearing his "ear phones" to monitor knocking, and "just in case his girlfriend called to say dinner was ready" :P.

The test we did were:

1) Broquet B40 (retails $500 fitted) Unit connected between the fuel filter & engine to manufacturers specs.

2) Broquet Top Fueller Competition (retails $1200 fitted) Unit connected between the fuel filter & engine to manufacturers specs.

3) Non of the above, back to stock standard fuel line.

A couple of things, we generally spoke about, were maybe these units don't have the same effect on cars pushing higher HP running Premium ULP. In our tests it failed to show any conclusive difference, and we decide to return the car back to normal.

I will upload the graph tomorrow.

I hope you didnt have to pay for these to test them?

thanks for putting up the results.

Edit:

You mention perhaps they weren't meant for big HP cars, but by the sound of the name, and the cost, of the second unit you tried, it wasnt designed for hyundai excels used by old ladies:)

I have attached the dyno sheet.

The 3 test are as follows:

1) fuel check

This test is done without any fuel catalyst, with the cars fuel system returned to stock

2) big red check

Nige decide to call this test Big Red, coz the unit looks like a uranium bomb. This is the apparnent top of the range unit "Top Fueller" retailing for $1200. see pic below. It is supposed to handle upto 1000hp.

3) AFC Tune

This test was done using the B40 unit retailing for $500.

I'm not too technical on the dyno graph reading etc etc, but on the advice of the boys, we concluded the unit had no real effect as claimed by the manufacturer.

I fairness to the monufacturer, they did say give the car around 3-5000Km and see if there is any difference without the unit...

Those AFRs are quite different between each run though..

Any reason for that?

If the computer was returned to suit the different conditions it might change the results somewhat?

Looks to be about 0.7 difference in the AFRs.

Would there be much difference in tuning it to this?

    • Clutch is a spec brand, new clutch system,( PP, flywheel, friction disc, etc. pull type) installed 100 miles ago, with no problems.
    • looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drove beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?
