Do engine mods change BSFC mapping?
Given the interest in mods of the engine as well as mods of the nut behind the wheel, I wonder...
Is it possible that I have changed the location of the "sweet spot" island on my car's BSFC map by modifying the engine with a WAI, an ignition timing advance by 2*, and removing PS, AC belts, and most alternator electrical load? The car on balance probably has more hp at the wheels now, no? In theory, should that change my BSFC mapping any? I would think it would. What do you think?
If I have changed the BSFC map then I need to readjust the nut behind the wheel... I should expect peak efficiency at load in different parts of the RPM arc than with the stock engine, no? What am I failing to understand that counts?
