Thread: EGR blanking kit

I must do mine....

Basically it comes down to clean cooler air being used in the combustion process. Also all sensors involved are at their optimum, as the heat, oil and soot that is usually returned to be re-combusted are gone. As for the auto it is adaptive and is responding to the small performance improvements. The car is now probable performing as when it was new, the small slide in performance is generally not noticed by most drivers as it takes place over a couple of years, BUT when it is "fixed" the difference is noticeable.
You will also notice your oil will stay clean longer, with the reduction in soot etc, having the effect of better lubrication and longer engine life.

As a followup...there is a long fairly steep hill not far from home. Usually the R.R. kicked back to 3rd and revved to 3000rpm going up this hill. Since blanking the EGR system it now flies up in 4th gear, even trying to drop into top if I ease off the pedal. YAHOO

Sounds like a good result with your TD6. Now to see if a TDV8 can be done.

My understanding of how it improves performance goes like this. With the old EGR setup, hot air is diverted from the exhaust into the air intake. This would have two undesirable properties. Firstly it would consist of burned gases probably with no oxygen in it. This could upset the air fuel mixture causing the motor to run rich. Secondly, being hot it would be less dense than cold air, lowering the compression slightly. It seems that cold dense oxygenated air would certainly improve performance and lower fuel use, as I have found in my case. If this poor explanation is wrong please correct me. Jim

They say and well the idea is that the system actually believe it or not reduces combustion temps and reduces emission's by doing so (that's a basic explanation)

At the end of the day clean cool air is better than hot re burnt crap and what you want in any engine...and gives better efficiency (power and economy).... by then further removing the stupid egr valve it can only help the overall flow of things even more and I bet having all exhaust gasses passing immediately thru the turbo creates better response even if its only a small difference, then I wonder also about how well the egr seals when its old and if boost to some degree is lost etc

I blanked two of my TD6 cars off now and the results are just as you say.. its a no brainer

A further followup to my vehicle. Before removal 11.4 l/100k around town (n.w. Sydney) Following removal after approx 150l of diesel is 9.8 l/100k for the same driving situation.

Thats excellent Jimbo . But I believe that it will settle down over time and get back closer to pre removel figures. Lets know what happens long term
