After seeing others' compression tests on RB25's, I really question wtf was up with mine.
I'll be sure to post it up later this evening when I can give exact figures, but mine varied between 125psi and 135psi dry (unsure if warm or not tbh)
It never burns oil. Oil level never drops between services (5 - 7500kms) and I had very minimal blowby. Am now running 15psi through it, and makes 285rwkw.
Either the test was done incorrectly, the pressure tester thingywatsit is faulty, or I have a rebuilt engine with lower compression. Sorry to hijack a brand new thread, but don't spose I could get any insight on my situation?
I'll be sure to get another pressure test+leak down done when I put turbo back on and take for retune - will be at a different workshop to the first test too.
