what fuel ratio's for what situations/boost levels?
what fuel ratio's are required for different situations?
i have been out mapping the fuel again due to the vacume hose not being connected to the fuel regulator last time it was mapped and i was runing out of fuel with cosie greens at 14 psi
i have been aiming for..
idle to 5psi 14.7 to 14:1
then blend up to 8 psi 13:1
then blend up to 12psi 12.5:1
then up to just over a bar @ 250 bhp aim for 12:1
and up to 22psi 11.5:1
my c/r is 7.7:1 with accralite pistons farndon H section rods
am i about right with my fuel ratios ?
please discuss fuel ratios for crusing overtaking on the motorway whatever
cheers

well idle = 14.0 - 14.7
cruise up to 1/2 throttle = 14.0 - 15.1
upto 8 psi 12.4
high boost 11.8 - 12.0.
but also matters on your exhaust gas temps, if there high, then run richer to be safe.
i run a 875oC max at 1inch from turbo, but try to keep it at 825 - 850 and 11.8 - 12.0 on full boost.
