Methylcyclopentadienyl manganese tricarbonyl.
Basically a replacement for good old
tetraethyl lead. Has health effects similar
to what lead did to brains and bodies (ugly).
I wouldn't want to breathe it out of someone
else's exhaust.
Allegedly does not poison catalysts the way
that TEL did. Does reportedly cake up on
spark plugs and valves. I would avoid it.
There is a further real bummer in all this.
It's perfectly possible to formulate clean
green gasoline of high octane and sell it
for a reasonable price. Ask any chemical
engineer with the right background.
Unfortunately, our elected representatives
in the political system found it made their
campaign contributors very happy when they
insisted that gasoline have oxygenates in
it to, quote, "clean the air".
Never mind that they -don't- clean the air
and that the National Academy of Sciences
agrees that they don't.
No, oxygenates mandatory! That means MTBE
or ethanol. MTBE is a petrochemical product
(big profits for oil companies) and ethanol
mostly comes from refined corn (big profits
for agribusiness).
Eventually MTBE turns out to be a pretty
hideous poison and groundwater contaminant
(which was never considered when Congress
insisted it go in our gas). And sorta kinda
a monster carcinogen. Ooops. Bye-bye MTBE.
So now Californians get rogered on octane
because ethanol is required. It's not that
ethanol itself causes detonation. If you
use enough it'll boost octane. But it is
the COST of adding the eth that kills us.
The refiners end up using a cheaper process
for the gasoline itself, to offset the high
cost of the ethanol they have to purchase
to blend in.
Your government at work.

I blocked off the EGR and bypassed the coolant from the Tbody to help keep intake temps down to help reduce the chances of detonation.

Wow. . .that was a really good explanation Chris Thorne. Thanks!
Which leads me to another question. . . what percentage ethanol would one want to add to gasoline to make it a higher octane. I work at a lab and 200 proof ethanol comes a dime-a-dozen. I've also heard that toluene can be used.
Hey, if I could mix my own high octane gas, that would be great!!!! http://www.hostboard.com/ubb/biggrin.gif

I find myself wondering what the massive attraction in California is...
lets see...earthquakes, riots, expensive low octane gas, floods, fires, mudslides...
I am happily staying right here in Florida where 93 octane is plentiful, hurricanes are rare, and it's always racing season http://www.hostboard.com/ubb/biggrin.gif

Marc,
EGR is not a bad thing. If you can believe it, recirculating the exhaust gas actually lowers the temperature of your intake charge and reduces detonation. It also reduces octane requirements. That's why all super high compression engines have it. It's also why a stock Camaro with 10.5:1 compression can run on 87 octane. It's not just there to reduce NOx. If you don't believe my expert engineer opinion, check this link on detonation.

Don't you know that in California, it's always sunny, all of the women are beautiful, everyone surfs all day long, and there is no crime.
