For you guys trying to size turbos for your power goals:

I saw this on Facebook and saved. Hopefully I can decipher it all LOL

I'm assuming we can set up formulas in excel to make this stuff easier?

 

Yup, I just made a spreadsheet in Excel to calculate everything.

 

This is no difficult stuff, I'm sure you will work it out properly.



Remember though, if in search of a new turbo, the calculated results, even with real specific values of your setup,is only a pragmatical approximation not the actual outcome of a future build setup as other external factors fall into place which are not included into the equations and software applications used.

Not to mention none of us actually know the true VE or BSFC of our engines. These calculators should really be used as more of a guide.


With cars like the Evo, you can really just search the internet (or just this site) and find pretty good data on most turbos as far as power and boost threshold characteristics are concerned.

 

Absolutely. I just like to see the "why" and "how" of it.😀
