Title: Free Turbo Calculator--works for double compounds
Post by: 0 Xero 0 on April 14, 2013, 01:17:34 pm

Hi, everyone, I've been doing research on builds for two different turbo systems and I've scoured the internet to find out how to correctly size turbos. Squirrel performance and Not2Fast have decent calculators, but they are lacking and a little off on their some formulas. All the information to size turbos is out there, but it's hard to find, so I made my own calculator. It's fairly intuitive to use I think. If anyone on here is a turbo guru, please feel free to chime, especially if I made any errors. Be sure to read the notes section. You need to know how to read a compressor map to properly use this tool. I have links to my compressor map collection too.

I've gotten some critiques on it, and I think it's pretty polished at this point. I tried to make everything as simple to understand as possible, but there's a lot of technical things going on in it. I some people on here find it useful!

Very nice excel sheet, but your link needs fixing.

Sorry about that! I posted this on another forum and apparently this site doesn't support the same html code for hyperlinking. It should be fixed now.

I don't know how to interpret turbo compressor map but there is still some useful info here for me anyhow.

Mush appreciated.
