Plod's HDi 140

[plod]

You do know that the droplink thingy adjusts the tracking on the rear tyre too and not just the camber, so you may want to get the tracking checked.

If it ain't one thing it's his brother

[plod]

so does the d9 consul drop straight in ?
do you still want these rear calipers?

Console - yes, just needs cigarette lighter holed opening up to take the D8 one ( i.e. you have the correct wiring, otherwise you'll need to change plug for it )

I had the rears before mate, it was the fronts
I'll have the MFD plug as well if you've got it please

[plod]

Finally sourced the MFD plugs thanks to Ade1122 over on the coupe club, and also bought a replacement drivers side electric seat switch

Want to get the seat out anyway
I sold the ecu and wiring I had off Gary, but for some reason, the guy Gary bought it off has a green and yellow wire going to the live connections
Just seems wrong
Common sense is telling me to remove from the live connections, and connect to the earths
Oh yeah, I didn't say, I sold it, then at my own expense, have spent £4.60 on more wiring, and paying my mate to extend the wiring
Yeah, I know, I must be mad, but it's helping a fellow 406 owner, so hey, must score me some brownie points when I reach the pearlie gates
I also directed the buyer to this site, so hopefully he's registered in last few days

dave i would try and earth that cable in the power ?

could well be the earth to the drivers seat heated function ???

Definately not for the heated seat function, as I virtually had the 2 seperate looms apart mate
It goes to the 2 plugs that go into the seat for the movement

I think I will earth it Gary
I think the guy doing the conversions has made a bit of mistake

[Gary406]

the guy i got it off was called gavin the coupe breaker. lives near ade

Anyone been following the modified airbox threads over on the coupe club?

I'm tempted to buy a K&N, which can be had off the bay for £35 posted, and try the ducting

I've got some shopping coming from sainsbury's in morning, so could amend the order to add some mayo!

no

so does it work? or is it all noise and no go?

[plod]

or is it all noise and no go?

Basically





Yes

[plod]

Yes

They reckon it's a big improvement on the V6

Principle should still work on other engines though
Someone else commented that on a 2.2HDi the K&N made a big difference, but I know from comments they're not rated on this forum

ifound after market filters make a car sound like a blocked Hoova

it a good noise going through a tunnel tho, but no improvement in performance, iused Pipercross filters

That's the thing Lozz
Saying it needs mods to the induction for the engine to reap the benefits of the filter
Filter on it's own is no good

[lozz]

if there was somewhere you couid fit the filter away from the engine it wouid be ok,
theres no where ican see on the 406 to house a filter where it wont soak up engine heat ,
couid have it low down near the lowest grill but then theres the chance of Hydrolockin the engine if it went through a decent puddle,

iwas thinking of just ripping out my air con rad and adding a bigger inter cooler other than that icarnt see anything else that will improve performance,

so far ive got it mapped, its de cat -ed and the actuator rod on the turbo as been alterd acouple of MMs,
dont think theres any thing else that can be done on the Hdi ,

Im still trying to work out if the pumps on the hdi are Governd, (restricted in some way)

The thread on the Coupe Club forums (found here, but you need to register on their forums to see it) reveals this to be the process:

1. Remove the airbox and the "knitted sock" air induction pipe from the engine bay
2. Disconnect the "knitted sock" from the bottom of the airbox
3. Cover up the hole where the "sock" used to connect in to the airbox - a plastic cat food tin cover, or mayonnaise jar lid have been proven to fit perfectly
4. Cut a rectangular hole in the front of the airbox (the flat surface facing the radiator)
5. Go to B&Q and get some "Manrose" brand flat rectangular ventilation ducting - 1 metre (although you only need 8.5 cm), and 2 x Vertical 90 degree bend fittings and a hot glue gun or a silicone cartridge gun to seal the pipework into the rectangular hole cut in the face of the airbox lower section
6. Construct the vent ducting so it is basically Z shaped
7. Attach the duct to the hole you cut in the airbox
8. Ensure the top part of the duct points towards the front of the car, and clears the radiator, without preventing the bonnet from shutting

You will end up with this:



Hey presto, you have an air scoop, all for less than £50!

Tatsfield reckoned that the standard airbox and induction pipe does not supply the engine with enough air, meaning that if you have a K&N panel filter, it is basically passing just as much air through it as the standard paper filter element does, hence no performance gain.

With this solution, you get a ram-air scenario - you have a constant source of cold air being shoved into the air filter box, through the K&N filter, and into the engine. More cold air means a hotter and more efficient bang (more of the combustible matter will be ignited, giving a bigger bang. The ECU will also provide more fuel to keep the fuel/air ratio correct, thus meaning a bigger bang than normal.

Seriously, this mod plus a stainless exhaust, and you could realistically achieve a good, noticeable effect.

And best of all, the car will be less likely to suffer from hydrolock, given the better location for the induction pipe.

Neat idea, but two observations:

1) Ain't gonna work on a diesel, as this bit of ducting is occupying the same space as the intercooler / manifold pipe work. (A 2.2 Hdi's got even more stuff in the way).

2) If you want some Manrose ducting, Google it for a lot less than B&Q, (online elcetrical wholesalers & the like).
