Sir;
I aploogise for not answering or attempting to answer. Truth is I can't come close to guessing. There are so many things in initial design machine work, tolerances, and assembly techniques that differ between different builders that can influence or affect final outcome that I never will guess at what a car or engine can do unless it is my design and is my build. I will on occasion make a rough estimate if I throughly know the work of another builder.
Sorry but I can't help. would like to but can't.
Ed
