a real T25 as found on a ca18det ( other called T25H or T25G are closer to a T28 ) outputs IATS around 150-160°C at 15psi . After going through a big cooling core (admitedly not the better), i had it down to around 60°C.
At that pressuren the turbo is overspinning and has such crappy efficiency it has no flow.
