Cat conv. and performance

Over and out

You are wrong about the asthma. Years ago be for emissions people didn't suffer much from asthma. When they introduced the cats on cars, they produced another gas, I can't remember the name but it is that rotten egg smell and that is what has brought on the asthma that doctors have had to deal with in the 70's to present. Now everybody and their dog has breathing problems and allergies.

Cats bad!

No Cats good.

And 20 HP more!

I don't think you really understand what you think you understand, but that's ok you are entitled to your believe your mis-information. CATS GOOD, EMISSION CONTROLS GOOD, The rotten egg smell is from poorly refined fuel, it is sulfur, in Calif. we have better and cleaner burning gas, the sulfur smell has been gone years with the introduction of low sulfur diesel and gasoline. And by the way Ozone is a big factor in poor lung fuction, i.e. asthma and COPD, which my father inlaw died from. I have been involved in the air polution issue since the 1970's, you are out of your league.

I agree, we need to reexamine our thinking on performance modification or face the consequences both legally and environmentally.

Could you provide the reference for this quote? Thanks

If you don't like pollution, move out of the city and into the country, I live in Canada and you can breath free, no smog, and drink out of the creeks. Stop poluting up stream and stop living so close to each other, in the cities.

Where I live we still have some dirt roads, just like dukes of hazzard. If I recall the general lee didn't have cats

Done and gone

Proof is a hard thing to prove.

So calimexifornia gets better gas than the rest of the country is allowed to have?

How about we compromise, you send us this special non poluting gas and we'll use it to run cleaner with our non-cat cars...then they'll be at about the same level as the cat cars running on our subquality gas.

Yea, and at the $4.00+ a gallon price they are paying??? NO WAY!!

[nelson84]

Ya get your head out of the sand.

[nelson84]

Are they driving without cats in greenland too?

I want to say/ask a few things.

1) I have never taken the catalytic converter off of a car. And I have no plans to do so.
2) In order for catalytic converters to work properly, the engine has to run richer than normal. This increases the amount of fuel burned, increases the amount of Carbon released into the atmosphere, and lowers mpg.
3) Catalytic converters are estimated to produce 50% of the N2O released into the atmosphere. DiNitrous Oxide is safe to breathe, but is a potent green house gas. N20 has 296 times the impact on Global Warming than C02 per mass. N20 is the 3rd most dangerous greenhouse gas even though it is only 0.00005% of the atmosphere.
4) Catalytic Converters require platinum or palladium. The roughly 15% of these metals comes from Russia and they aren't exactly known for their environmentally friendly industries.
5) The largest producer of Methane Gas in California is cattle.
6) Electric cars are very clean, but unless you live near a nuclear power plant, you probably charge the car with power from a coal burning power plant. How many piles per pound of coal do you get? Which is worse, to burn 1 pound of gasoline or 1 pound of coal?

I'm not saying that Converters are bad, but they are far from perfect. Instead of focusing on cars built yesterday, we should focus on cars being built today. Like the 2008 Corvette that has 430 hp AND emissions equipment.

That's not a verifiable source now is that? You were writing like you were some sort of scientist so I assumed that you were. My bad.

[nelson84]

I hope he isn't a scientist or we are all screwed. I will cost me $ to bring it back to emission legal for now I will enjoy the extra 20 HP
