boost question

[Tony 156]

should my ko3s drop from 20psi to 10psi by around 6000 rpm?

Have no logs to go on and have checked for leaks and all is good there. Just wanting to know really.

Cheers all

Tony

Its impossible to tell you with such vague information if you have a boost problem however, it is normal for boost pressure to drop around the higher rev range.

I have a K03 and it peaks at about 21Psi at around 3500 revs and drops to just 10Psi at 6000 revs.

sounds normal to me..

 

[Tony 156]

sounds good.

Cheers guys.

that sounds a bit low for k03s...

 

[Tony 156]

how so?

Was playing with the idea of changing the actuator for a forge one but it seems that the general concencus is it will cause boost spikes and i will see my internals come through the bonnet!

as johhnyblease wrote..he has the same numbers as yours with k03..
i also get about 20 psi on 3000 but i get around 12 on 6000 mark,,
i think u should be able to have more boost in upper revs with k03s...
