Hi everyone.

Got the car mapped and dyno'ed yesterday. It did not make as much as expected.

But does the boost control for the N75 look normal?

 
It's a biggish T28 from a Nissan Pulsar. Just wondered if the steady increase in boost is normal for the N75.

Max boost was about 17-18 psi

That would depend on the mapping of the ECU.My stock K04 has a huge surge in boost, 1.7bar then drops holds 1.5bar which then tails off gradually to about 1bar at redline.

Also from the Dyno, it says MBAR x 0.1, you reached Max=126 according to the graph, so 126 x 0.1 = 12.6psi.I am not sure when you are getting 17psi from.

1 millibar = 0.0145037738

max mbar = 1260

max psi = 18.27
