Subject: Catalysator, performance, blah, blah, blah...


Hi guys,

I got lots of responses re: catalysator and performance...

Most of you think that the use of a cat does not affect performance at all.

My question is how come two cars with the same engines do have a difference
in horsepower when one of them runs with a cat and unleaded fuel?

On the other hand it might be the fuel that makes the difference. Companies
recommend unleaded fuel to show an environmental-friendly image. As a
matter of fact it has been underlined (MOTO Magazine, Greece - Article on
researching fuels) that the use of unleaded fuel without a catalysator is
much worse for the environment than using super (or 4*). Some engineers
also reckon that engines without a cat run much much better on super fuel
(and better performance), no matter the "unleaded" sticker on the top of
your tank.

Anybody who has proffessional experience or scientific knowledge, please
give us your lights...

George
