Default Compressor map calculator (program inside ) :)

Id like to share something i've put together with you guys

Pretty much it was Raining over here nothing to do and i was reading on the Garrett webpage and i did the calculations to work out what turbo for this horsepower on paper then figered this is annoying for people to do so i put together a calcuator on Excel with the popular compressor maps to see what i came up with. it's pretty cool to play around with.

All the data i used is from the garrett website.

If anyone wants me to add other compressor maps tell me and send them over and i'll be happy to

Enjoy.
Change log:
1.01 - Removed doubled up compressor map changed doubled gtx3071 map
1.1 - Maps wernt lined up with grid.
Pressure Ratio v1.1

Pretty cool. I typed in some numbers, though I don't know what 1/2 of those mean... and it puts red dots on the charts!

i didn't know what half of the number ment untill i researched them. and that's why i left some there incase some didn't know. It's pretty usefull to help you pick your next turbo. it won't give you exact results but it's a rought idea.

Do any maps for the old KKKs exist? I race in a stock class so can't change the turbo, but I'm curious about how it compares.

Hi Paulyy,

I know it's been a few years since this conversation was active, but I'd like to ask you to put another turbo map into excel calculator.
I am working on a final project for university in which I am trying to examine a few ways of charging specific engine.
The turbo I need is Garrett's G25-550, and it's maps are listed in the following link:
https://www.turbobygarrett.com/turbo...series-g25-550

If you get my notification and help me it would be very helpful.

King regards

I'd like to see this too actually. The new G series looks quite interesting. I might get one after they come down in price and I get bored of the vittesse stg 2 that I'm gonna install soon.

Damn, I haven't used this in a while. forgot how useful it was.

To them up on other compressor maps, just get the 2 final values (Pressure ratio) and (airflow lb/min) and look at them on any compressor map.

But i'll try and add it.
