Read the oil control thread. Beyond all the talk about restrictors and external drains, there is solid info on the best sort of closed circuit catch can system. Open catch cans and deactivated PCV is a shit idea.

Why is this?

Whats the issue with the PCV being blocked off?

Street legality = zero.

Fumey smells = the suck.

It not being hard to actually achieve a multi stage catch can with proper pcv functionality = enough of a reason to go to that amount of effort rather than cheaping out.

As long as it wont damage anything thats fine.

Only reason mines like that at the moment is because im such a cheap ass i havnt got a place to attach it into my intake

That said, ive never had Smells or Smoke coming from it.

yer its just my highmount set up doesnt have a spot on the intake pipe to add that third line

That's a weak reason.

You havee been asking about getting someone to fab a catch can.

Get them to add it to to the inlet pipe.

^ Cal ya show off :)

Had to be done lol. I dunno people seem to get mental about catch cans but mine works alright for a mild-medium setup lol. Plus I like my photo :)

and as above, I have a fitting welded onto my intake for the catch can. The bungs can be bought easy as, theres no problem at all sourcing them. It would cost bugger all to have it welded on. If he is making a catch can I dare say if you supply the fitting he will weld it on for free

That's a weak reason.

Thats a fair point. I just bought all the lines and fitting for the car and the can it was coming with feel through. so now im stuck with a heap of fittings nd braided line. hence trying to find a fab guy so i can get it made to exactly how i need it

My tuner blocked my pcv up saying it causes problems with the nistune

Any truth to that, or is he seeing a placebo affect?

yep, with any AFM setup if you're introducing "un-metered" air from the atmosphere it will cause all sorts of issues.. hence if you're running an AFM setup with a vented catch can you need to delete the PCV

    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
