Defender TD5 Wastegate adjustment

I thought you would have had a few gauges considering the mods

to rule out a collapsing air intake pipe try it with the air filter or remove the intake pipe and test drive .....under bonnet temps can make a hose more softer and you might be right by a hose collapsing but it maybe heat related due to engine load ...also remove all boost hoses and inspect to make sure the inner layer isn't separating
or try removing the boost box to rule out this isn't playing up

Cheers I took the bonnet off and drove it up the road and could see the intake collapsing at the bend. Undid the snorkel and all is fine. The "boost box" is built into the ECU. What gauges would you recommend?

Boost gauge.

It's on the list!!

not many people like adding in gauges they think its some what eye sore or looks to futuristic

make sure there is no restriction in the snorkel I have seen bees and wasps make nests inside them depending if the car gets hardly used
make sure no one has played jokes by stuffing a rag down there ..all it takes is one person in the car park that you may of ****ed off
how clean is the air filter and age ?

depending on your modifications
if its been remapped an EGT gauge
if you play with turbo adjustment .. boost gauge is needed ... reading should be manifold pressure
mechanical boost gauge would be the better choice ..for other reasons

trust me once you installing gauges you become more custom ...when you guys get heat waves ...you will also notice just by reading the gauges that there is a change

The boost gauge is an easy swap for the clock but not sure where would be sensible to put an EGT gauge. Air filter is 500 miles old. We've never looked in the snorkel !

egt gauge doesn't go in the air filter this is installed in exhaust flow ..this gives a reading of exhaust gas temps ...its basicsally classed as an early warning device unless you want to rely on the coolant gauge specially if the ECU has been modified

I do apoligise I read wrong ...the sensor is placed in the closest position as possible before the turbo outlet .

I meant the gauge itself not the probe!!! lol

i do apoligise ..i have read wrong ..i have added to my last post

I've seen these before has anyone else ? http://www.4x4overlander.com/product/madman-exhaust-gas-temperature-meter-egt1-including-probe-2/

Could fit this one, should be enough space in the dash for it.

Yes, were discussed last week in the 200tdi

That looks good and a lot cheaper than the Madman one. Where they say "also comes with weld on bung for easier installation" what does that mean?

Just remembered! You can get multigauges specifically Boost/EGT in one gauge.

The probe has to be install on the exhaust manifold which means either drill and tapping it, welding a bung on or using the Madman EGT adapter which fits on the EGR blank (not quite as accurate but easiest to install.

So could this (http://www.ebay.co.uk/itm/162128287049) be installed by tapping the egr blanking plate? I'm not keen on drilling the manifold

Something like this (!) http://www.ebay.co.uk/itm/LANDROVER...epid=0&hash=item25b974f18f:g:0sYAAOSwJQdW~lGG

Exactly. That plate screws over where the blank is however use proper hex bolts not allen heads. The allen heads round off VERY easily.

exactly this will not be a true reading.... this is why you need to install in the correct location this way it see the full affect of exhaust gasses escaping

How far out would it be though? I'd accept some inaccuracy in return for not having to drill the manifold !

allot as there is no flow from each pot ...for example if number 5 piston was to burn up for unknowing reasons .... what good is the sensor at the EGR side ?

getting back to your issue ..regardless of how new he air filter is it appears you have some intake issues ..snorkel has been confirmed that its helped ...engine EGTS also create higher under bonnet temps this could also be a fatigued thing

Depends on the length of the probe really.
