Triumph TR6 - Fuelcat

Hi guys,

Just perchased a Fuelcat to get the car running on unleaded fuel. Instead of rebuilding the engine head, the Fuelcat is installed inline of then fuel filter. If needed the car is returned to "original" very easily. It works for over 400.000 km !


see link: http://www.fuelcat.co.uk/mainpage.html

Is it known in the States ?

Eric - I drove my TR3A for 43,000 miles on unleaded. By then, the valve seat recession had become serious. So I had the head rebuilt to run on unleaded. I put in 8 new valve guides and 8 new valves. Since then, I've driven another 35,000 miles and haven't had to re-gap the valve clearances once. i check them every 5,000 miles.

I admit that the head is no longer as per the original, but it's better - and not one Concours Judge can tell that it has been modified at any US of Canadian Natiuonal TR Club Concours.

Eric - I've never heard of it, and the site really doesn't say what the "catalyst" is supposed to do...

Brent,

You're right. It doesn't explain much. See the next link for more info;

Why didn't I think of that!
John Parfitt

What I meant was what sort of chemical reaction that stuff is catalyzing so as to accomplish the remarkable claims. Umm - I must admit I am skeptical about any benefits from the product.

I think it's known by its other name "snake oil".
Also, I have some land for sale in Florida you might
be interested in.

TO QUOTE FROM THEIR OWN TEXT

"It's not known precisely how the Fuelcat works - but it certainly does seem to"

SEEM TO!!??? - well maybe near enough is good enough for them !!

I am very sceptical about this Eric - be careful!!

Could I trade some of my bridge stock for a fuelcat?

Roger,

I'll try to translate the Dutch suppliers explanation to English language (sorry for the spelling errors!);"

"Inside the Fuelcat there is a tube of tin that adds microscopical parts of tin to the passing fuel. By the burning of the fuel, the tin becomes tindioxide wich leaves a "film" (thin layer) on the valves, pistons etc.)No need for leaded fuel anymore. Better running engine and the engine oil keeps much cleaner. Works for over 400.000 km. It only works with passing fuel, so no worry's if the car's not running".

I've informed by some oldtimer dealers. A lot of them know the product and also uses it. Good references. Does indeed do what they promiss it will do.

I'll keep you guys up to date with my own results on the car.

I've read that some contend that the unleaded fuel concern is exagerated. If so, it is consistent that such a product would certainly 'seem to work'!

Eric,
The Federation of British Historic Vehicle Clubs commisioned a laboratory test of several additives but no tin-based type was not submitted for testing. Practical Classics magazine does not accept any adverts for additives that claim to prevent valve seat recession without this evidence.

The test for recesssion involved running a Morris Minor type of engine at IIRC 3500rpm for the 'equivalent of 5000 miles'and recession was easily measured on unprotected exhaust valves. If you plan running your TR6 at 3500rpm continuosly then you might hit problems afer a few thousand miles, but only after the lead-memory (ie lead that has diffused into the seats since the last valve-grind) has worn off. It's those two parameters that can disguise an ineffective additive. Without lab test data I would not rely on any additive! BTW I use Millers VSP.
