when you get into repeated builds like BP crate motors or like the racings my brother does, you have build history and specs of hundreds, along with Cosworth factory specs and there were only so many cam specs like 25 so it’s predictable, if you use these cams, C/R and has this fuel flow / AFR the HP/TQ should be this. That’s why when you see all the data and something looks fishy it usually stinks…. Figures don’t lie, but liars sure do figure…
