Moving the timing belt around a gear tooth or 2 is even cheaper 
This seems like a possible idea! An 11% increase in combustion efficiency sounds like a huge jump! Factor in the Atkinson cycle will provide more C.E., and you have quite the efficient engine.
How on earth would I keep the boost so low? Would I have the turbo wastegated at 2 psi? Big turbo?
Also, if my engine responds decently well to becoming a 1.0 2 cylinder, would this mean I could run more boost at low rpm? There's so many variables to consider!
All I know is for the time being I want to get the wideband installed and get lean burn working better than it has. I am seeing no increase in mpg so far  |
You wouldn't have to have the turbo wastegated at 2 psi and up to 6 psi. The proper choice in a turbo would only get you the low boost numbers, with out anything going through the gate.
With the low Cd it still looks like the you would be running in N/A even with a 1.0 L equivalent. This why i would run all four cylinders in a Atkinson cycle N/A and pull one tappet per cylinder to help with swirl. The when needed get into a mid-load and start making some boost in lean burn. This will accelerate the car up to speed and go back into light load steady state.
