No its not rocket science,but there are a lot of things happening at the same time ,not many of them linear, so trying to do spreadsheets and ratios ,and get accurate data is impossible .
even the throttle size/opening and filter and all intake pipework ,can effect the boost ,and the quality of air output
Im sure your efforts and intentions are good ,but the answers not that easy to predict. and the biggest and most important of all the factors are thermal inefficiencies ,a combination of effects.
Quality of boost air pressure is more important than the quantity of boost pressure,and Flow is what should be investigated and tabulated .
Oh indeed, that's why i don't intend on produce 'a' formula, i intend on measuring and looking up the study of it and coming back with a range of answers.
The main reason i'm doing it is to see what can be done with the standard set up as i refuse to beleive it can't be improved and it's easier to replace when it goes bang
