How to adjust for minimum Brake Specific Fuel Consumption?
How do you adjust the spark and fuel to obtain minimum BSFC without an attending loss in power? Combustion efficiency is maximized when BSFC is minimum.
BSFC and maximum torque should occur at or near the same RPM.
Is this the same or similar process to the Auto VE process?
Is there a graph for the LS1 engine showing BMEP - Brake Mean Effective Pressure against engine speed?

Neil.

This is the best I can find
I have a generic set of curves for a petrol engine. The diagram comes from a text I 'liberated' from the internet, it runs to over 1100 pages but it does have a lot of theory. The basic problem is that the big dip in the BSFC curve that mirrors the torque curve is less pronounced at lass than WOT.
If you are interested in a looong read PM me, the book is 19.4Mb in size and was published in 2001 (13th edition), so a lot of it getting a little old.
