Turbo

[gazz]

Hi
Is it possible to make the turbo come in sooner than in 3000 rpm ?
In Pajero it is possible I am told.

Hi GAZ ,
What vehicle is yours ?

Góðan daginn!

does your car have the EGR valve?

if so, blocking this should bring it in sooner. follow

I did'nt think the turbo kicked in as late as that :? thought it came in about 2000rpm :roll:

well to be honest I duont feel it kick in at any rpm.
But I was told at the local Nissan dealer that it should come in at about 3000 rpm
But this is mine first diesel car, our Pajero did have 3,5 lV6 petrol engine

mine comes in at about 1700rpm, but you notice it more at about 2000

surely blocking the egr valve shouldnt make any difference as its only open when on idle? all other times its closed (unless faulty)

gazz, there is/was a topic open about fitting a manual boost controller to the turbo, you might be interested in it

Yes I will look onto that, we did take run now and dear o dear this car is so strange.
Now it won´t rev up smoothly it hesitates around 1200 - 1500 and after that then it revs like normal.
Any idea ?
I have mention it some time before that this car have bean out of the factory on a bad Monday, but now the wife says it must bean Friday the 13 on full moon
Please commit on this new problem.

one more thing, if I take the + of the batteries does the cero the ECU ?
And if so how long time do I have to have the connect off the batteries to clear the ECU is ok to take the - terminals ?

Hi again gazz.
I always thought that turbos were supposed to"kick in" at some particular stage but I now know better since I fitted a boost gauge to see what was really happening.
The turbo starts spinning as soon as the engine is started (being driven by the exhaust gasses) but it doesn't really blow much air ---BOOST--- until the engine starts to work harder. My turbo starts to give some usefull boost at about 1300rpm and at 2500rpm and above it is giving max safe boost of about 13psi. The boost build up is certainly quick but not a sudden KICK. So if your car pulls away quickly and goes uphill easily then you can be sure that your turbo is working, otherwise your car would soon be struggling for power.
So, for me anyway, the myth of boost kick-in on these cars is eliminated.
Hope this helps you not to be too concerned about the apparent lack of boost just because you don't feel a kick ! In my experience turbos are smooth, silent operators. :smile:

ECU reset

If you disconnect the batts for at least 20mins (as advised off an oz site forum), Whatever adjustments you've made to boost or EGR valve etc, the ECU will reset along with these adjustments after being disconnected for at least 20mins. (as I understand it). Hope this helps you ? :|
