Thread: New Defender towing

And while I'm relatively happy with the way my 300Tdi goes, (3" exhaust, fuel turned up so that 720* can be exceeded on a long climb, 80mm hose feeding the air cleaner from the snorkel, etc) and it's loaded with gear every day, there's no doubt our stock GU does the towing and carrying thing just that little bit easier.
The Landy is a little faster (more power) and the Nissan hangs on about the same or a little better on hills (more torque, much larger capacity) and is obvioulsy better at the bottom end and in engine braking.
The Nissan is only using 7psi boost and a very restrictive exhaust.
I have to keep an eye on both water temps, and obviously an eye on the Land Rover with EGT's.
Funny thing is that the 300Tdi is actually better at idle and stall speed, but when it stalls it's instant.

MTQ claimed they'd found that on a couple of GU's prior to modding the turbo and pump timing. It actually sounds like they were retarded a fair bit so it wouldn't mean piston temps were too high, but still...

i heard that nissan was doing this on the 4.2td to reduce emissions. retard the timing which will increase EGT which will reduce emissions. they werent making the same power as before and probably not as efficent either...

Wish my EGTs were that low on a long uphill, mine get up too 650+, I usually have to back off the throttle or go back a gear to keep the revs up and use a trailing throttle, to get them down into the mid 500s, which slows my progress somewhat, I drive by my EGTs now, cruising on the freeway with no hills it sits around the 380 to 400c.

Funny how little towing information there is posted here about new Defender. The new engine and gearbox make for a different tow vehicle to the older ones.

well you tow dont you? wheres your info??

I just fitted a new engine to a GU (ZD30), it was pulling 760 upstream unladen up a moderate hill in about half a km on a test drive

It felt like it would easily see 800+, and the owner pulls a 20ft van , so EEEKKKK

He watches it like a hawk now, and is stunned at how much heat there must've been there when towing with the old engine...

Getting back to the original Q, the customers I have with '09 models are VERY happy, you couldn't prise them from the drivers seat for anything.
They all report excellent fuel economy, and at least one of them actually loads it right up AND beats it to death in the bush regularly.

I'd say go for it!!
