Re: THe NAC Lots-O-Post Thread aka North America Home Owners Association Thread
That's much too general of a statement.
14.7:1 is the ideal stoichiometric mixture. That gets thrown right out the window depending on the motor, injection setup, and whole hell of a lot of other variables. For instance, since my injection is GM TBI style, it likes to idle around 13.8-14.0:1. And then under load/acceleration, I have it pulled down to 12.5:1.
You absolutely can go 15:1, 16:1, and even 17:1 while tuning for optimum cruise fuel economy (aka lighter loads, and usually 2-3k rpms). Again that depends on the motor.
If you have much less than 1 part of gas to 14 parts of air your motor will fail sooner than normal. In the 70's there was the Pogue carburetor that had warming coils in the float bowl causing the fuel to expand before going through the jets.
