Re: Clogged cat?
The catalytic converter certainly does reduce CO. I work in R & D of a large
company that designs and manufactures catalyts. The CO reduction we see is
about 99.8 % removal when averaged thru all the phases of the test. (This
is reducing percent level CO emissions to less than a hundred ppm). BTW,
once heated after starting, well made catalysts will actually remove 100 %
of the CO an engine makes during regular driving modes.
But they certainly don't make your turbo very happy...or make you fast.
