One downside might be if only focusing on VP index is it don't account for VE%, eg.. does compressing less fuel/air higher equal, better, worse than compressing more fuel/air lower ?
That and other things is why you say I bust AJ’s balls on the assumptions. There are a bunch of holes I can shoot fish in a barrel with.
Overall, AJ is fine and his post above isn’t worth loading the gun over. Some of the engine build has to be on the builder/car owner to consider and work out. AJ wasn’t asked to build an engine for him. He was just pointing something out. Everything can and should be adjusted for “YOUR” build and what you’re looking to achieve.
