ok ppl i need too know what i need too keep and what i can get rid of in the engine bay im running a wolf 3d plug and play ???? im removing the cruise control i want too remove the charcoal canister and all the emissions **** but not sure of all the vacuum lines and stuff any help would be great i am removing the engine this weekend in way for the new one next weekend

Why oh why would you want to take the cannister out ? It stores vapours from the fuel tank for the next time the engine runs and that gives you more power when its burnt - you dont want fuel to go to atmosphere and waste it now do you ? Its not a carby you know its EFI...

Not to mention vapour lock

"Vapor lock is a problem that mostly affects gasoline-fuelled internal combustion engines. It occurs when the liquid fuel changes state from liquid to gas while still in the fuel delivery system. This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling. Restarting the engine from this state may be difficult. The fuel can vaporise due to being heated by the engine, by the local climate or due to a lower boiling point at high altitude. In regions where higher volatility fuels are used during the winter to improve the starting of the engine, the use of "winter" fuels during the summer can cause vapor lock to occur more readily." Wheres that letter to the editor.... Some original photos have not been recovered yet.

Ah there are actually TWO cannisters in the VLT, The emissions one to store the vapours - the charcoal cannister, with extra VLT valving for boost operation etc. And the plastic black pressure storage cannister under the inlet manifold, in winter you wont need it much and some people get by with minor annoyance of vapour lock during summer but I notice a big difference as I tend to run my engine quite a bit leaner so its hotter and heatsoaks badly, have big trouble starting mine without the pressure storage cannister. I'm also keeping my charcoal cannister as its a great way to add a double fuel option for things like waste isopropanol but need to get the ECU upgraded with a wide band O2 for that - toooo much to think about, let alone actually do..!

you guys know your stuff, id never take it out but a charcoal canister is very ugly looking.

mmm, might be able to put it near the fuel tank, as long as the outlet vapours from the cannister dont end up getting condensed and becoming liquid, would only happen for a few seconds in cold weather but hey why not, make a small trap with a bleed back to fuel tank You'd just have to run a couple more rubber pipes, low pressure cheapies. That way its out of the engine bay and still has the benefit. Some original photos have not been recovered yet.

Cheers Guys Didnt Know Thats What It Was For

while we are on the topic of charcoal canisters, what do you have to do to the n/a vl plenum/canister setup to run boost?? I havent done anything and its runnning fine so far,just making sure. I havent really ever looked to see how it all works, but how does fuel vapour get into the cannister??

The only prob with a n/a cannister with boost is pushing the vapours out the bottom vent. An easy fix is a one-way valve in the line from the cannister to the inlet manifold. The fuel tank has a vent relief to the cannister and it should hold a little minimal pressure if all is working well - so you should hear a "whoosh" when you open the petrol tank filler cap, if there is none then you are venting vapours either from some broken pipes around the tank (old ones will perish and crack) or from cannister setup. All those vapours over time will cost you fuel, especially in summer and in winter the air can get in and condense out water and gradually it can build up... edit: Should be able to get a VLT cannister cheap enough from a wreckers... edit: 2 Here's the update on the VLT cannister, little more complex than a one way valve, makes sense though as it ensures cannister purged even on boost too so its completely refreshed to be able to store the max vapours next time you switch off etc...

thanks heaps for that NICHE. How much boost could leak out of the bottom vent on the NA canister, it would be negligible wouldnt it, not enough to effect a/f ratio much would it??

Wont affect A/f, though even if there was any sort of leak it would be very very small and would make it run slightly richer but only at boost, that vent has a pretty major seal on it - partly a safety and (afaik) a factory access - not used in normal operation... ie. The body of the activated carbon within the cannister doesnt get much above atmosphere for long as there is a restriction to its feed by virtue of the small pipes leading to it and more than likely a restrictor inside the valving anyway,

cheers mate, ill probably just leave it for a while at least until i can afford to get a vlt one, none of the wreckers around here have vlt's
