running the turbo out of the specs !!
Like the k03S running at 20 psi
when it is made for like 11 psi

why have i seen so many people running between 10-20psi for a looooooooooong time on the k03s???...from what i have seen most people that do get chipped run the same k03s for like 80k miles+ ....is this just luck??...what would be a safe number to keep the k03s at then?...capping it at 20psi with an overboost kit?...

Re: (WhiteG60)

also...keep in mind, the turbo becomes hotter as more exhaust gas flows through it.....to reach 20+ psi the wastegate is closed completely and thus driving all the gases through the turbine. This increases the heat + stress on the turbine and then the heat is dispersed into the cooling + oil. Heat indirectly causes more strain on the turbo. But you cannot make more power on a Ko3 without causing it to cook. Hence the number of blown turbos.

Has nothing to do with boost, its TEMPERATURE. It just happens that running high boost out of a turbos efficiency makes it hotter .

right.. running more boost = more spin = more heat = more stress on the journal bearing etc..
