Boost?

[arbess]

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.

Im getting a poping noise as it hits rev limit but other than that...

LOL

I am having trouble atm but this is mostlly due to the forst winter with the summber pfc tune...

Its getting re-tuned next thursday

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

[WazR32GTSt]

it might be the SAU stickers on the side that upped the boost

i've heard of people getting up to 1psi per sticker...

[Col-GTSX]

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...

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.

[chaos]

yeh but that's just the avc-r. Not all EBC's will spike

[Col-GTSX]

I use the SPC baked beans and spegitti for hungry little human beings...

I mean the SBC ID III D spec which is a fully automatic boost controler and comes with a price tag to boot...

[Col-GTSX]

If ye do a ye old fashion searche. Ye will discover a topic that I'd done on the benifits between AVCR vs SBC ID....

Ummmm

[Mushroom]

it also comes to layout, quality of airlines etc but the electronic controllers are better than the bleed types

[arbess]

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, =)

this is because avc-r is junk compared to some of the newer ebcs on the market

[The Dan]

Col did you say you are getting a retune for the colder weather?

Unless your PFC is D-Jetro, why bother? The ECU compensates for colder air as it measures the temperature via the MAF meter. You should only need one tune and that's it.

[Col-GTSX]

Yeah its D-jetro...

[The Dan]

lol.....are you being serious? I can't tell.

[Col-GTSX]

Yeah... I posted ages ago that i fry'ed my pfc and that i had ordered a D-Jetro...

Well its time for it to be tuned...

[HR32_GTS-T]

maybe u shouldnt smoke as many cones at night that stuff makes u see lots of things. haha

[The Dan]

I think mine spiked to 21psi the other night....couldn't be sure though as my guage only goes to 20.
