Hi,

Is anyone elses boost going up a little more than usual in this current weather state? Mines nearly reaching the +7mmHG, im thinking around 10-12psi.

This is at night of course.

turn your undercar neons off and everything will go back to normal.

Its common knowledge that undercar neons will increase your boost levels, even on NA 4 Cylinder's

You will notice more performance at night comming into winter due to the colder dencer air...

This is common for any car... Cause if the air is 10 degres cooler entering the air filter its gonna be 10 degres cooler at the throttle body (allow for some variance of course)...

This in turn will make the turbo sound different and improve performance... But i have seen boost increase under stock control or with a bleed valve....

Us with electronic boost controllers dont see these things happen anymore...

I've been told with the avc-r (electronic boost) that it can still spike.

i'm running 1.2bar of boost (17psi) and the guys who tuned it said it could spike to about 1.3bar of boost during cold weather.

Haha, my neons are off haha. Yeh i understand the colder air theory, we all did year 12 science. But i would of thought the actuator and the wastegate would of controlled all the increase and ONLY slightly increase the boost. Isuppose thats the way it goes.

Anyways is your car doing it? for those who dont have the SPC SBC ABC PFC PFFFFFFT systems, =)

I just ran some injector cleaner through her. started roughly the first time after adding it but gave it the beans slowly upto 4k, Must have cleaned a few cobwebs out. another step in the right direction for the sub
    • Sadly I can confirm if you are actually seeking to drift, you will quite easily spin up one wheel. Even if you're going in a straight line. I am not entirely sure of the metrics/terminology here but there's only a certain amount that the helical will actually spin both wheels. I've seen it on video with my own car where two lines of smoke switch over to just one after you really get in to it. Unlike with a clutch diff where you can keep your foot planted until the car regains grip, in my experience with the helical you want to be utilizing traction control allowing LIMITED slip or lifting (partially) when you start to spin up both tyres with a Nissan helical. Which makes them pretty sub optimal for drifting duty. That said... this is probably a helical on numbers alone. Just put the Kazz in
    • Let's just fix the problem by f**king the rest of the gearbox.
    • Unlikely, as per Greg's post. This is not helical diff behaviour unless one wheel is up off the ground. Shimming what? You don't "shim" a mechanical LSD. Probably not in the sense that you have heard of people "shimming" a diff. And the process that Nissan f**kwits call "shimming" a diff involves super-preloading a VLSD cartridge against the side of the diff to create a friction/wear point (in a place that it wasn't supposed to have one) to make the sloppy, useless, viscous diff into a hybrid viscous/mech abortion. In case it isn't clear, I consider the process to be stupid. Nike.
    • How much does the shifter move when the car is in gear with the engine off? If it is more than about 1cm you need to replace your shifter bush. Your shifts will just get crunchier, not faster, with a short shifter unless you also rebuild the whole box
