Do these work? Any experiences?

Visited the Alexandra Palace "Classic" Car Show last Sunday and was fairly disapointed (no P6 bits in the autojumble!!!). But I noticed two "performance enhancing" devices being pedalled quite forcefully and wondered if anyone has any experience of them.

The first is called "Fuel Cat" (there is I believe another brand name for an identical product). This is a capsule in the fuel tank or in the fuel line of metal pellets made from an alloy of Tin, Zinc and Magnesium. Apparenly developed in 1942 by a British engineer to alloy Hawker Hurricanes to fly on Russian 85 Octane fuel and which is now, it is claimed, allowing classic cars to run on 95 RON unleaded with no modification. Apparently the tin ups the RON, the Zinc protects the valve seats and the magnesium reduces combustion temperature.

Now I remember these coming out in the early nineties or late eighties, when the unleaded tax advantage first arrived, but had thought that they faded into oblivion. Clearly I'm wrong about that and whilst sceptical that they work wondered if anyone has tried one and with what results?

The second device, has me completely stumped. I can't remember what it's called but it claims to increase power, reduce emmisions and reduce fuel consumption on any car fitted with electronic fuel injection. It consists of a nicely made aluminium box with two wires fitted with cheap brass U terminals and connects across the battery terminals and to nowhere else. Now I'm not an expert on ECUs but can someone please tell me how this can work?
 
Both items certainly work to enhance the bank balances of those selling them, other than that (IMHO) no chance.
 
They are not endorsed by the FBHVC (as not tested) but generally accepted that no independant body can catagorical say that they do work.
To me, that means they don't! Save your money.

The device fitted across the battery terminals, all I can suggest is that somehow lowers the battery voltage slightly, which in theory could reduce the injector opening, hence allowing less fuel in. But I can't really see how this would work without putting a massive load across the battery, which would soon have it flat !

Here's a good site that pretty much poo-poos all devices http://www.fuelsaving.info/index.htm
 
My grandfather purchased one of those pellet things.
We put it in a coffee jar of petrol 5 years ago. Nothings happened so far but i'll let you know if anything changes....
 
I put these pellets in my SE6 scimitar in 1986. Ran the car on unleaded for 5 years, 40k, with no probs. Sold the car for a good sum to assist with property purchase.
Use normal unleaded in my 2000sc with castrol valvemaster+
