i've heard the stock bov on a skyline can handle about 1bar of boost right?

what would happen if you exceeded that, say to 1.5bar

going for a dyno run on friday and want to run 1.5 but then will wind it down quite a lot for everyday driving, so the question, is it alright to exceed the 1bar limit occasionally?

Thanks INASNT and all who replied.

By my calculations 1.5bar is approx 23psi. right or worng?

So according to the answers here that is more than the BOV can handle theoretically.

Will it do any damage if i pump 1.5bar through it on 1 occasion?

what turbo are you planning to run 1.5 bar through? and constant 1.5 bar in the engine and the pistons and rods are not gonna be happy either, it will be time for forged pistons and short penned rods. Try use a turbo where around 1 bar will give u the power u want!

Yeah mate, i wont be running that high boost much of the time, only on the dyno and possibly if i ever take it to the drags.

turbo is a bit of a mystery, another reason i'm taking it to the place its being tuned is to find out.

its either a t04 or GT30.

it is rated a 600hp though :D

I don't think that you will have a problem with the bov leaking.

it is more the fact that when the bov has to actually "BLOW OFF" it might not be able to handle THAT much pressure.

so you might get the compressor surge sound (fluttering.)

if you want, I have a NEW GFB HYBRID bov for sale.

$200

it plumbs back and vents to atmosphere at the same time so you don't have the back fire issues..

and they can handle ALOT more than 1.5 Bar boost.

yes it makes a pssh sound.

no you can't just say it's a plumb back because there is a entry for the plumb back and on the opposite side there is a trumpet for the atmo.

oh by the way..

I can read your sig and I have been getting laid..

so what now?

hahahaha

very clever though.

      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.
