Default Looking for log information. Boost vrs RPM
S4 Crowd.
I need to find different examples of the boost onset curve for K04's K03's and any varient.

Sort of like this one by Minhea

For research.
Thanks.

Default To what end? Maybe someone can answer your question.
I can tell you right now, the actual/requested curve doesn't come close to telling you the entire story.

Mihnea's got worked K04's, so that wouldn't be a good example of plain K04 spool characteristics

Default You need one that starts 2000
2000~4000 is the interesting part when comparing to bigger turbos

Default Well, the end.. Is to see how much energy is available to the compressor wheel on the K04.
Get a base line on the K04's so it can be compared to anything else.

Default That log is determined by programming...
You should look for some MBC-only data.

So your saying a standard K04 unit might exhibit faster boost onset?
