I'm very tempted by it if I don't get on with the turboed LD28 in the 6x6. Just today was pootling around and it dropped oil pressure when warm. Might be a number of things (including dodgy gauge) so I'm not being inspired with confidence in it yet. put a cummins in there with a heavy duty R380 from ashcroft and a 1,6 transfer case and you will have a seriously serious offroad load carrying machine, got any pics of your 6x6?

Ed Poore Posted March 12, 2020 Share Posted March 12, 2020 See my signature for a link to a thread for more details. It's got a factory standard LT95 in there with integrated transfer case, supposedly the LT95 itself is very strong albeit a 4 speed box. Off-road pah not so much - with rusted up leaf springs it struggles on my driveways at the moment, no flex and an open diffs means loss of traction is very easy. Current plan is to get it on the road and see how the engine feels / behaves itself, by all accounts it's a capable engine once turbo charged (which it is) so we'll see. It's just of unknown origin since the chap who had it before died suddenly and although we know it came out of a working vehicle don't even know the mileage on it.

Ed Poore Posted March 12, 2020 Share Posted March 12, 2020 The turbo charged straight six straight through exhaust and stack does sound nice though! Quote Link to comment Share on other sites More sharing options...
Badger110 Posted March 12, 2020 Share Posted March 12, 2020 Feck that looks nice in there! Quote Link to comment Share on other sites More sharing options...

More cylinders means more, smaller, lumps and less stress which is how boxes seem to survive better behind large petrol V8's than things like the TGV or Isuzu / Nissan / etc. diesel 4-bangers even though they're making similar torque on paper - 400nm over 8 bangs is half the "peak" of 400nm in 4 bangs. 1 Quote Link to comment Share on other sites More sharing options...

That's part of the reason I'm hesitant over the R2.8 - if it had been a 6 cylinder I'd have jumped on it. As it is I'm cautious. Quote Link to comment Share on other sites More sharing options...
Popular Post bodumatau Posted July 10, 2020 Author Popular Post Share Posted July 10, 2020 a little update to the project.. Cummins SA is in the final stages of the installation and has taken the vehicle to the test track for some testing. they hook it up to a truck with a gearbox retarder so they can push the engine to max power and max torque output and then check if the temperatures stabilise under constant load. Cummins team was happy with the temps achieved and using some math will be calculating the Limiting Ambient Operating temperature (important for us in Botswana where 45 degrees in the shade happens every year) this is what it looks like next is to try the standard TD5 cooling pack (radiator and intercooler) and see if they can achieve the same results 5 Quote Link to comment Share on other sites More sharing options...

I think we can be pretty confident this is the case - the old LT76 seems to tolerate V8s better than Tdis, even though the V8 figures are higher.
