That is what I am going to try and do with my high compression 8L engine. That 11:1 compression engine should idle fine be able to do some lean burn, cruise down the road on regular gas.
Then I was going to use water and methanol to make it continue to run well at wide open throttle where premium would be needed.
I have to make it work or I will be stuck buying premium gas which costs 40 to 60 cents more per gallon.
When the engine was installed in my suburban, when it was a 7.4L about a 20% increase in fuel milage by setting up the carburetor for lean burn.
First round with the 7.4L I put a slightly under sized carb on there, tuned it for lean burn.
This time I am trying high compression, more cubic inches, lean burn, a larger but still under sized carb and water/methanol injection.
