RE: Octane

["Dave Dahlgren" <ddahlgren@snet.net>]

You might want to read this and think about it a little more..
http://www.ercracingfuels.com/sxs1.htm  please explain the BTU concept
again??

here some others to ponder...

There is a lot more to fuel chemistry than just the octane number. how the
number is achieved IE the additive package as well as the percentage of
aromatic hydrocarbons all play a part in it.. You might want to consider how
Honda ran 58 lbs of boost in a 1.5 liter F1 engine for hours on end and only
had a so called 102 RON fuel. The answer is in the last link (part4 of the
series of 4).. gasoline is a chemical soup with lots of interesting
properties and I don't think you can hang on the values of just a few of
those and make an intelligent decision on fuels.

Just for good measure I stumbled on this link as well. It is about engine
balance but a good read by someone that seems to have a clue if reading the
referenced material at the end.

There is a ton of good info on the net just read to see if they reference
known sources or are just giving you their favorite new theory.
