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
