Whoops, yes I was. So yeah the k03 is good to 18psi :) lol

I wouldn't say the K03 is good to 18psi.  At 10 psi you can actually feel the drop in high-end power.  If someone wants to run more than 15 psi, then the K03 is not the turbo to use, especially on a 1.9. 

It's basically the same turbo as in the AHU/1Zs that runs 15-18psi though isn't it?

Tyler

just because it will build 18psi, does not mean it is doing it efficiently...

Actually, Yes. 18psi is right where the efficiency really drops off the face of the planet for the k03. Without an inter cooler really ANY boost is hot air that isn't doing as much as it could be if it were cold. SO with an inter cooler, 15-18psi has been with no ill side effects on k03 turbo's.

If a K24 can do ~28 psi, and a k14 can do ~23 psi, why can't the next size down feasibly do ~18 psi?

Andrew I have heard tale of AHU's boosting 11-13 psi for stock boost pressure. Since what we are both saying is non-factual, who has a bone stock AHU in a mk3 to test this out? lol

I was quoting the factory max boost spec.

My friends B4 is boosting 20 PSI, but his wastegate is sticky so that doesn't count. If I can find my boost gauge I'll see what mine is boosting, it's stock. Doesn't mean it's working right though.

I believe Andrew though.

Oh, I am sorry. I did not see it cited that you were quoting factory specifications. Easy to get misinformed on the interwebs.
