bosch VE land rover 300tdi - puglove - 19-04-2015
Kinda like an xud so thought this would be the right place for it
Been off roading today a developed a strange boost issue
Pull through the rev range as normall >>>>>> full boost 2800 rpm (20psi) >>>>> fine all normal
Rev on through to 3000rpm >>>> instant drop to 0 psi >>>> LOADS of coal >>>>>> no power
Change up to >>>> 2000ish rpm >>>> normal boost/ power >>>> normal coal
Hit 3000 rpm ish >>>> same again no boost lots of coal
Wtf is that?? Im really confussed.
No obvious boost leaks
No sound to idicate that its dumping 20psi of boost isntantly
New CHRA about 6monts / 1000miles ago
It isnt the gauge at fault indicated by the huge amounts of coal and lack of power.
How can a turbo stop spinning instantly with 3000 rmp of exhaust gas running through it then spin up fine again the next min???

boost leak - possibly something coming loose at high airflow/pressure

Intake pipe collapsing?
RE: bosch VE land rover 300tdi - Paul_13 - 20-04-2015
Does sound like that.
Intake pipe collapsing and sucking shut
RE: bosch VE land rover 300tdi - maxlee - 12-05-2015
has the small pipe rubbed through from the top of the pump common on them
intake pipe shouldn't collapse as they are fairly tuff, filters not full of shit and its lifting that up in the box?

Get a boost gauge on it see whats happening
RE: bosch VE land rover 300tdi - JTaylor2005 - 13-05-2015
Tbf I was looking at one of these the other day. The long turbo to air box pipe round the back could be collapsing if the air filter is clogged up.

There's ya problem
RE: bosch VE land rover 300tdi - darrenjlobb - 18-05-2015
Only just seen this, heh yeah was going to say , you have a pre turbo intake problem, classic issue of something closing up under high airflow! This is a classic problem on long silicon intakes on XUD's etc!
