Surely after that exhaust turbo IC there going to reject your claims if anything engine or driveline related decides to pack it in, and rightly so.

Also why unless your trying to turn a defender into a sports car, change the turbo the standard variable geometry turbo is pretty good, keeps the boost steady pretty much all the time with virtually no lag?

Please don't take offence in the way I've asked these questions I'm just interested.

I've got 9 months left of warranty. After 3 rear diffs, front prop shaft, 1 clutch,gearbox output shaft, gearbox shims, 1 gearbox, I finally felt like it's been sorted. Basically have had a brand new drive train installed.
That's why I have done these mods.
It's a lot more pleasurable to drive.

Hi Stewie,
Yeah a bigger intercooler should reduce EGT's, but the extra turbo boost and power would negate this a bit, compared to a standard tune and intercooler.
Removing the cat is supposed to help as well.

Im planning to change the thermostat to a lower temp at some point too, but I dont expect this to have any real effect on EGT's, more for a 'safety margin' in hot weather.

Cheers

As Tombie pointed out, if you're a bit "mechanically unsympathetic" and really lug or labour a car in high gear at low rpm, it's not just the high egts that result but the rest of the drivetrain that won't really thank you for it either.
At lower rpm there are fewer engine pulses, so each one is bigger, resulting in higher levels of torsional vibration and more potential for driveline issues.
Given some of the issues owners have had with backlash/replacement diffs/fretting of driveshaft and hub splines and so on, I don't see why you'd do it.
Coming from a Tdi disco, I'm as guilty as anyone of using the 6th gear in the Puma at lower rpm than I should, but there are 5 other gears to choose from....!

So true. I also recorded an almost instant 5 degrees difference in coolant temperature between 5th and 6th gear at about 80km/h on the flat.

It seems the puma engine really likes to be doing its work above 2000rpm.

Exactly. Make it work... These diesels unlike older ones like to rev

And the intake temp. Try 16 degrees ambient and ~50 degrees at intake manifold

.

Drop a gear, let the revs come up, less turbo boost needed and the intake temp drops by ~20-25 degrees!

It'll be interesting to see how much difference the Allisport makes. See if this "LIFT" technology lives up to the hype!
