There is the Excel file I built after learning advanced turbo stuff on Garrett Turbo Tech sections, 2 years ago.I ask to anybody who found a logical or data error to tell me and help me make it more accurate as possible.

Yellow cells = you must enter values
Red cells = don't touch those cells : they are constant or formula
Green cells = results you may use with the compressor data plot

Thanks

DISCLAMER : the numbers in this file are those I think they should be but I don't claim they are accurate at 100% The main goal of this file is to give a good idea of how it is working and how to read a turbo (compressor turbine) data plot.

Awesome Sebas, thanks for uploading that file. Guys read the turbo tutorials and this sheet will make more sense.

Remember. If you guys find something wrong with a cell wihtin the Excel sheet, just tell me, I wanna know.
By the way, my Excel sheet demonstrate how hard it is to find the good turbo for the engine and the application we wanna do with it. I made a lot of tries before getting closer to point I want.

F****d up

Man, I finished all the classes & I've been taking my final exam trying to plot my graphs & determine the right turbo for me. This is some hard shit, I feel like I'm back in college studying calculus, physics, chemistry, something til' I'm getting dizzy.

Here it is 2am in the morning, knowing I gotta get up for work in 3 1/2hrs & I'm seeing double.

I really want to understand this shit, but can't ya'll just tell me what to get? I trust you guys.

Haha dude you sound like me, I get obsessed with research at times and sometimes will stay up all night to work on something. It doesn't go over too well with the wife at times. I think if you got the basics though you can make a relatively informed choice and can sift through the BS that gets thrown around every once in awhile on the net. Plus we got some good smart guys on this board that will do the major R&D for us.

Great Thread. I think I'm gonna enjoy reading these tech files. For now i'll just save them so I can get some other things done before the Genesis finally comes our way.

Nice excel sheet.

Try putting in the stock HP values at max RPM and see if your PSI is zero. That should be a good double check. At 306HP I'm still getting about 3.75PSI. In order to get it to be 0 PSI (atmospheric) your A/F Ration would have to be 9.94
