Thread: 2000km in the High Country/ Defender TDCI 130

How about an exhaust brake?
Just put a butterfly valve t the exhaust pipe

My puma doesn't produce much engine brake too. Going downhill very easy to rev up to 4k.....

Cheers

Following the down hill braking discussion. The Isuzu bushfire truck we have with exhaust brake is very effective in the right gear. Coming off Mt Glorious NW of Brisbane you can descend the whole way without touching the foot brake.

Have often wondered what one of these would be like SGV Exhaust Brakes I have asked for a quote on a cable operated system which is only listed in the obtain a quote page

19.0 for 300TDi, 17.5 for ZSD. Would have thought that was sufficient, but I guess it's the weight thing, same reason they seem underpowered.

Go the whole hog and fit a hydraulic retarder!

The exhaust braking issue has been raised before, from memory the valve train assembly on the TDCI will not cope. Would love to hear from someone who has gone ahead and fitted one though.

Surprised to hear you say first low downhill is too fast as I've had to accelerate downhill in our 2009 110 with TC.

DiscoMick, I can't comment on the TDCI 110's performance, never driven one. It comes down to weight, steepness of track and Mr Gravity. With the TDCI 130, Mr Gravity does not have to try too hard.... Mind you, when we had the old F100, he had even less of a battle!

Sounds like a good trip Rich. Hope you can wrestle control of the camera from the navigator next time.
I haven't had any off road fun in way too long, but I remember trading my V8 auto D1 for my 2002 TD5 130 and was introduced into a whole new world of relaxing descending. You now have me wondering if my STEEP descents were not anywhere near as steep as I remember them.
