air fuel ratio with boost
#11
Also seeing some talk about the stock ford mapping for the supercharged cobra in the low 10 range AFR .
As far as the Vette engine , obviously they are shooting for safety. And supposedly the stock blower causes some high IAT readings.
I'm sure there's some power on the table by pulling a bit of fuel out, but I don't see a ZR1 blowing gobs of black smoke and washing the rings out of it .

Now remember that is in a rolling vehicle, the load on a marine motor would justify this even more. IMO

The 2 I've put widebands on would run in the 13 at cruise and only drop to 12.7/9.real scary,tried adjusting regulator for more fuel up top and it did nothing but richen the bottom a little.ended up having Marc boos add some fuel.
And the timing they run,wow.I'd never tune like that.

But 13lbs of boost was 12.7ish to 13.3 depending on load.the motor has a fuel pressure compensation table and we brought it up to it's limit.tried to cheat it a little.
Boats were 42 and 46 outerlimits.
