what’s behind the fogs

[philip]

having removed my mud guards and the fogs, I discovered that on the nearside, the twin horns are right behind the fog light. More interestingly theres an interesting looking tall black box rectangular/cubic shape about 30cm tall and 10x10cm base with a flexible wire/hose going from its top into the bottom of the engine bay. Needless to say the horns and that box are on my way for some ducting to the brakes etc.

Anybody knows what that black box is?????? and has anybody relocated it and the horns to make some room down there?

yeah I noticed that too....must be some kind of air intake or outake

Ahh f**k knows, I just like to make a mess

Charcoal filter, dumped mine when i dumped the fuel tanks!

 

[Chris_H]

charcoal filter is on the offside of the car, thats the drivers side on RHD cars.

 

[philip]

charcoal filter to filter what exactly????

 

[Chris_H]

petrol fumes my good fellow.

At certain times the fumes are purged into the inlet manifold.

If it is the charcaol filter, which you need to firstly confirm!

The charcaol filter is plumbed to ur petrol tank(to extract vapour) and also connected to your throttle intake (to expel vapour)

Collects vapour as your car rests, fires it back into the engine when your movin!

Just controls vapour emissions( so u dont smell petrol when u open the cap)

ahhhaa, right that explains the second hose into the inlet manifold. okekoke.

Now back to relocating the horns and the filter.

The cup racers use vents and ducting straight through the fogs to the brakes, so I assume they have removed the horns as these would be of little use on circuit (lol ...), what about the filter jobby then, they must have removed or relocated this somewhere else??

sorry aint got one

So what happens if you smell petrol in your car, does this mean the charcoal filter thingymajig is fecked?

I get a very strong smell of petrol in my car when I fill it up to the max

I previously had the seal around the fuel gauge sender unit changed but that didnt help...I think vapours are still escaping from there....possibly the vapour hose blocked?

Sorry for changing the topic philip.......

p.s. for some reason fuel smell gets stronger when the windows are down

 

[weight]

Honestly dont know!

Check all the usualls, hoses for splits, clips, tanks for damage, filler neck, cap sealing properly.

Get under car and trace where the smell is commin from!

see if you can spot anything!

good luck!

One of these by any chance? I had to remove it to get my 75mm ducting down to the lower front grill. Remember to remove the solenoid from it and plug it back in to keep the ECU happy and close off the end of the vacuum hose that goes back to the inlet manifold.

i was gonna say that weird restrictor but since its not anything like what he described i didnt bother, plus i have no idea what it does! lol

Spent ages with the technitian talking about it, even Ren wouldnt give us an answer!

 

[Flying Scotsman]

.... seems to run fine without it though!

 

[BenR]

ditto.......i aint got one, well, not anymore.

Still, WTF does it do! lol

 

[weight]

Fek thats what you get in the 172/cup

WOW just look at the size of the dump valve on the side! piiissssssshhhhhtttttttttttt !!!!!!!!!!! hahahahahahahahaha!

 

[Flying Scotsman]

The only thing I can think off is that valve is closed when you cold start in really cold conditions so that warmer air is sucked from the second air duct which is drawing air higher up in the engine bay. I ran the car for a few weeks on the K&N before removing it but with the fabric duct removed so you could look down into the valve. I never ever seen it shut! Its default state is open. The vacuum obviously only operates the valve when the solenoid is activated by the ECU. When I took mine apart I also noticed that the in-line vacuum non-return valve was leaking, so i must have been loosing vacuum when running standard!

 

[weight]

Yup, sounds fair!

Forget all the talk of the charcoal filter then! LOL

 

[BenR]

Yea, we went over that, but it seemed illogical.......if they wanted hot air for cold starts then it would need to be near the exhaust manifold, since at cold, the engine bay is a single temp, there is no variation.

 

[BenR]

we were fobbed off with all sorts and Ren tried to tell us it was a speed limiter!>?

eh!

You sure its not exhaust fumes? when i took out my seats i got exhaust fumes comming through from under the car. opening the windows created a sucktion and made it smell worse. as soon as i put my new seats in the holes where plugged and i couldnt smell it again.

Probably useless, but I have told you now.
