What is load? Please read through so you can understand my thought process and tell me where I'm wrong.

I've seen that most tunes keep it at 192 and I've seen a few that post it around 240's and I've seen Tony post that the upper hard limit was 320. How do we get these numbers? I assumed that 192 is due to flow limitations of the turbo. I was under the impression that this was capped due to maximum permissible speed as displayed below. I believe I am wrong with my initial assumption but am posting what I had previously thought before.



With the information provided here:

Compressor map for K04


With relation to this:

RPM·········BAM (%)····BFV(%)
1000········97.0··········99.0
1720········128.1········129.8
2000········140.6········148.5
2100········147.4········154.5
2200········146.7········155.3
2520········140.8········166.5
3000········138.3········166.5
3520········140.9········166.5
4000········144.0········166.5
4520········151.8········177.0
5000········151.7········185.3
5520········157.7········171.8
5900········155.3········168.8
6000········153.0········160.5
6400········142.3········148.5
6800········130.1········144.0
via Doug S.

Seems like they would be representative. However how is this explained:




I can change KFMLDMX for the flow limitation, but what should my wot LDRXN be? (Say an awp 1.8t running a GT3076R.) This is now not stock flow limited or tapered, but what is now the upper limit for wot conditions? What am I not understanding? Is there a calculation? a guesstimate? a general rule?

Any help is appreciated.

Pick a pressure ratio. Convert to absolute pressure. Convert to load.
