1st; what is shaft play? is it when the turbo wheel moves so that it is not inline with the shaft?

2nd; Would shaft play results in a ticking/tapping sounds coming from the trubo, im not sure what the sound is but im almost 100% its coming from the turbo

The turbo is a vg20 (never been confirmed so could be anything) it takes ashit of abuses from me bouncing off the limiter and running 12psi

cheers michael

take it to hyperdrive

ask ken 10000 questions

then come back here and make a new thread

then take it to xspeed, ask ant 10000 questions

then make an update thread, then ask the same questions you asked ken and ant

then take it to top racing, ask steve 10000 questions

then come and here and make claims that your doing a turbo manifold gate upgrade, and a r33 gtr front end conversion

then make a thread about popping flames

      The oil pressure sensor for logging, does it happen to be the one that was slowly breaking out of the oil block? If it is,I would be ignoring your logs. You had a leak at the sensor which would mean it can't read accurately. It's a small hole at the sensor, and you had a small hole just before it, meaning you could have lost significant pressure reading.   As for brakes, if it's just fluid getting old, you won't necessarily end up with air sitting in the line. Bleed a shit tonne of fluid through so you effectively replace it and go again. Oh and, pay close attention to the pressure gauge while on track!

      I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.

      Nice, looks great. Nice work getting the factory parts also. Never know when you'll need them.

      I take it that the knock retard is from bearings tapping a little tune? Thicker oil is a fragile bandaid. You need a much bigger oil cooler and probably the bigger pump being discussed.
