Can someone tell me how this works?

ie. blocking off the 2 pipes and venting the third one under the car???

i dont even know what it does... all i know is that it is a carbon canister and is there for an emissions reason.

i refer to this...

well i did it today out of share boredom... if it has made a change it isnt too significant... maybe i can connect and disconnect them next time on a dyno to see what exactly it does do in regards to power

nope... still have no idea... perhaps something to do with the fuel vapor and the way it reacts with carbon/charcoal?

why disabling it would somehow give u more power i have no idea

Hey nark, if u read the FAQ man, it actually says:

"Remove the carbon canister (makes more room in the engine bay) "

This mod doesn't improve power in any way, but is done to free up space in the engine bay. The can gets in the way when making a CAI partition, and I'm sure other ppl have found it to be obtrusive for other reasons.

At least you have some more space in your engine bay now :)

The fuel tank has a vent to stop pressure build up when it warms up. Combustable gases under pressure are dangerous, so don't block it.

The carbon canister strips some of nastiness in fuel getting in the atmosphere. Removing it would be illegal, and if you do it at least make sure it doesn't vent onto some thing hot, like engine bits, brakes or some bugger's cigarette butt.

A good indication of a badly blocked carbon canister/lines is a HUGE rush of pressurised air/fuel vapours when the fuel cap is removed, i.e the system isn't doing what it was designed to do.

A minor amount of built up pressure on a hot day isn't anything to be majorly concered about however.

if u remove the carbon canister u will also get bad petrol vapour smell everytime u reverse or at the traffic lights if on idle for a long time!

whatsisname

My canister doesent seem to be blocked off and i dont get any petrol fumes in the car but when i take the filler lid off i do get rush of pressurised air comin out.

all unleaded cars get that rush.... i used to get it on my daewoo ffs lol

i think i will just relocate it then... cause i want to put a partition in as soon as poss.

thanks guys for clearing it up.

ummm, i think the carbon cannister is there to evacuate fuel vapours out of the inlet manifold back to the fuel tank, when the ambient temp is really high. and disconnecting it could cause explosion when u next start up and there is fuel vapours in your inlet manifold. it is more of a safety device than an enviromental one, and there could be no performance gain except weight reduction.

    • Actually everyone on the roads was really well behaved. The only person that did any minor tailgating was a local hoon in a Turbo Focus. Unfortunately we weren't going the same way so there was no grand initial D touge battle. Lots of people pulled over and let me through. The amount of "Hey man nice car, omg skyline, nice 34 man woo" was suprising. Like really suprising. Like almost annoying. My partner was obviously surprised, she'd never seen anyone in the real world point out the car/like the car/want to chat about the car before, so to have like 3 people per day mention it was notable, I could finally say SEE? SOMEONE THINKS THEY'RE COOL. Everyone was also pretty suprised about the weather. Every day was dry and about ~13-14C. Mount Wellington had a sign that said they close the gates at 9pm and I was heading up there at about ~7:30. It was VERY apparent that conditions were getting significantly worse by the minute on the way up and down. The road on the mountain was terrible though, it's no driving road. I have various suspension related questions now. Luckily it was only about 20 minutes from where we were staying to the top of the mountain as said Google maps. We only had the 2 nights in Hobart. We went to the Farm Gate Market though which was really good - And went down to the Hastings Thermal springs/caves down there during the day. I'd definitely be up for going back again, so luckily there's a few more sights yet to see. Didn't get to do the west coast/queenstown/cradle mountain so this was supposed to be a 'scouting' trip anyway of sorts if I were to one day do/take part in/organize a more car-focused trip. As for the boat, it wasn't bad. Well it was bad, but not in the way you're thinking. We did the night trip which leaves at 6:45 (though you have to be there ~2 hours earlier) and arrives the next morning at about 6am. There is nothing to do on the ship. If you plan accordingly and bring a book/tablet/show to watch/charger you can just chill out, take some Travacalm and just sleep through it. The food there is an extremely basic buffet that costs $32 a plate, or $14 for a $3 pizza. The way back we had a travel kettle and a few different types of cup noodles and made our own tea/coffee in the room. This was a far superior way to do it. At the very least book one of the rooms with beds. I guess as we were in the off season we didn't have room mates. You get an option for rooms with 4 beds (2x bunks) or a room with just the two bottom beds. There's also some option for a deluxe queen bed but it's much pricer. We've been on sleeper trains in Asia before so we figured this is similar (and it was)
    • You just gotta be really, really, really clear and decisive with what you want your end product to be. 99% of people who want this conversion aren't "I want to run a 295 front tyre!" so they don't really need the widebody. They just want the OEM body to look a little less dumpy, so bonnet, bar, skirts job done with some camber, stretch, slam. It's when you want that, but then decide to pivot later you get big problems. See also if you're willing to get an all in one fibreglass bar, and you're willing to accept fibreglass problems like cracking the entire item on a driveway, instead of just a piece attached to the bottom, etc etc etc. Decide this all before buyin'.
    • After @Kinkstaah debacle, I'd never want to try and get it right 😛
    • The hood lines up with the fenders. The front bar doesn't perfectly line up with the fenders where the wheel arch is. You have to 'squeeze' the front bar 'in' as it wants to naturally flare out and be longer on the sides. There's a few threads where people notice this when they only swap a GTR style bumper and front bar. Unless you have genuine OEM items - you may be better served getting conversion kits. There are GTT bumpers to fit GTR hoods. There are GTR hoods (non genuine) to fit the GTT bracketry. MAY
