Sort of on topic. Thinking of doing the EGR blank and getting a de-cat stainless steel exhaust.
Would all this put a lot of pressure on the turbo? Mistadave, what changes did you notice with your exhaust?

Quite the opposite, removing the CAT will reduce the stress on the turbo ie the exhaust gases will escape easier
A blocked CAT/DPF can spell the end for a turbo so get shot of it
The Decat will help MPG, increase power, extend the turbo life and probably outlast the van (stainless)

Nope, my van is a 2004 and I have both EGR blank + Decat pipe with no fault codes
Treat your van to a new K+N filter too for the full effect

BTW mine is a 56 plate (without a DPF) and fitting the EGR blank did not bring up any dash warning lights.
It appears that there are many simple things that can be done to improve the engine efficiency but if the EGR is blanked, the is cat taken out, no DPF, and then more efficient pipework installed, could this not increase the Nox emissions and therefore risk it failing the MOT? |

You will either have a CAT or DPF, not both
Diesels aint tested as stringently as petrols, I believe its really only a smoke test (which any diesel running half right will pass) and NOX etc is not measured

With all this new found power, have you boys taken out the plastic 'restrictor' behind the radiator grille, covering 40% of the inlet area????

Perhaps the build-up of soot and oil in the intercooler decreases the cooling effect the intercooler has - this will cause loss of performance and economy. The difference in power between the T4 without intercooler and with intercooler is 14 PS (88 V 102). I'm not sure all that power was down to the piddly little intercooler that the T4 has, but it seems that cool induction air really does bring a significant benefit - so the cooler it is, the better.
Last weekend I drove 120 miles with my banked EGR duct, sticking to the speed limits which I've never done before (most are 43 and 56 mph here in Latvia), and my van returned 47 mpg! (by MFD). I'll be doing a couple of long trips in August, so I'll be more sure of the benefits later.

Happy Yellow. 120 miles at 42-56 mph !!! That must be soul destroying
 And here's me thinking 10 miles of roadworks with 50mph average speed cameras is torture ! But having said that, I would love to get 47mpg. It will be interesting to see what a steady 50 will return with my new blacking plate fitted. Just also took my little plastic restrictor plate off . I will see if I can notice any difference later today.

It's an easy fit and likewise it's easy to remove so if you thought you might have a warranty issue I would remove it before taking it into the stealers.

I`d be more concerned about the fact that your van is a later model and they usually throw up an error code when the blanking plate is fitted which has two consequences:
1) A light on the dash (annoying)
2) A stored fault code in the ECU which the dealer can find/question if the ECU is interogated during a service (unless of course you clear the code with VCDS before the service
 ) |
