Max boost on a stock K04 turbo

Hi Guys

I've seen some data on the K04 compressor map and various comments on the net that the max pressure for a k04 on a sub 2.5L 4 cylinder engine is around 22psi?

Is this accurate as I've seen a lot of Cupra R's and Audi S3's running 27psi peak, tapering down to 24-25 pounds at redline!

Is this safe / wise?

thanks!

 

The K04 will do 1.85 bar (~27psi) only not for a very long time.

It is better to get the results from ignition and normal (20-21 psi) boost pressure.
You can expect 375-385 HP if there is enough fuel (hpfp).

 

You should look for the compressor map

 

^^ You can.
However I do agree with what Chris said from mapping experience.
