Got a good run, got good power but after 6000rpm it drops. Got any tips? Yes it runs little bit more rich at the end.

Its a build engine and its around 14 psi

it is measured at the wheels.

216whp@5864rpm
285wnm@4273rpm

18psi

Tip: don't ask vague questions.

Im sorry :( I will go to m.net for my vague question.


Well, is it the turbo that just runs out of flow or is my timing or something else?

I turned the BOV for more tension, its one from forge where i can adjust the tension of the valve. I tought that it maybe couldnt hold the pressure and it looks better now,

I don't know a lot about the Mitsu turbos, but I assume it's just choking up at the top end. In fact I'm surprised you're able to hold 14psi as high as you do.

The turbine wheel is pretty small. Thats what causes the awesome spool. But thats also a problem at high rpm, its just out of flow. But you can see the difference between the first and second dynosheet.

7 psi@2500rpm
10 psi@2800rpm
12 psi@3000rpm
14 psi@3200rpm
