Ps...

I've been putting it in 'D' and in sports mode. Should I perhaps do it in '2' andin sports mode?

Aye you will notice the difference , mite need a change of pants if you floor it  Oh and keep an eye on the fuel gauge 

 

You reckon that will be faster?

Yep  Well it is in the 3.0 , never tried it in a 2.5 as never owned one

Right, I'm off to try all this without the spares...... on my private track of course

Yourve been gone too long now  Stop thrashing it

He ran out of petrol lol

He ran out of petrol lol

Maybe changing his pants

In the end couldn't do it.... my private track was busy 

As I'm going to drive it in '2' and thenget it to 60 will it get to the red line and sit there until I get to 60? Don't really fancy staying ON the red line for long

Dont forget the gearbox learns to the way you drive , at least it does when it works

There will be many variables when you do a 0-60mph time that will affect it slightly, like ambient air temperature, humidity, how warm engine, engine oil, gearbox and diff oil are. Tyre pressures and how hot you tyres are as this will marginally affect effective tyre diameter, all up weight etc., etc.

A way to eliminate all of these factors is Beachy Head, it is very good for a one off 0-120mph time.

Thanks Rods. So based on my initial post with my varied times you wouldn't be concerned that it doesn't do 9.5 bang on every timeand in fact gets slower some times?

EGR is part of a strategy to reduce NOX emissions ONLY and of no use for anything else. In the UK, MOT stations can't even measure NOX, so it remains part of the type approval of the vehicle when new.

inducing exhaust gas into combustion does affect the flame properties - basically it reduces peak combustion temperatures, which is where the NOX is formed. But it also reduces performance quite markedly.

EGR is used only when needed during the EC drive-cycle used for the type-approval test. Mainly during the cold-start part. Most of the EGR use during normal running is to keep the system working and not for an emissions purpose.

hope this helps

Thanks 2Woody, appreciate that.

On to the 0-60 results does it make sense about why the figures are different? Would you be concerned i had a performance issue (no pun) with those fluctuating times albeit max fluctuation being 1 second??

If you're measuring with a speedo and stopwatch I think any variation can be put down to the inaccuracy of the measurement method. I think you're doing well to get a spread of only a second, TBH.

Thanks Kev,

i shan't be concerned with it anymore
