atomization enhancement

[Todd....!!]

Hey Fred,

Ya mentioned that:
"According to all these manufacturers the higher the pressure the better
the combustion."

I'd like to add an additional note to what you mentioned, and that is
that the higher pressures create better ATOMIZATION of the fuel, and
thus create a finer/better air/fuel mixture, thus creating more power
thru a more thorough combustion cycle....

LATER!

Todd....!!
