tweetyduck Posted November 28, 2012 Share Posted November 28, 2012 We are going across mountain pass(s) at well over 5000 meters. What tweaks should I be prepared to do. More specifically how exactly do i do them. I'm obviously thinking fuel injection pump and turning down fuel. Thanks Neill Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted November 28, 2012 Share Posted November 28, 2012 Dont bother, the Pump will compensate for you. Quote Link to comment Share on other sites More sharing options...
Sirocco Posted November 28, 2012 Share Posted November 28, 2012 I wondered this to as we will be driving passes around 4500m in the Pamirs next year. Let us know how you get on in SA guys G Quote Link to comment Share on other sites More sharing options...
tweetyduck Posted November 28, 2012 Author Share Posted November 28, 2012 As much as it annoys people.... are you sure it can compensate for that altitude ? I'm sure someone told me to turn it down but cannot remember who to blame for me having to quiz you. ( I'm not meaning to annoy you or the people that will witness the black plume of unburnt diesel coming into Chili / Puru. I just don't want to end up not moving at some point due to not knowing something I should know. If you know what I mean ) Quote Link to comment Share on other sites More sharing options...
Don Del Posted November 29, 2012 Share Posted November 29, 2012 I drove a virtually new Puma from Santiago to La Paz a few years ago. I think the maximum elevation we went through would have been around 4,200 metres. There was a noticable drop of in power as you would expect from the reduced amount of oxygen available but on the whole driveable as long as I wasn't thinking about the possible harmful effects of the unburnt fuel. Clouds of black smoke on start up from cold but not too bad when hot. As far as 5,000 metres is concerned I think you might be approaching the limit. I vaguely remember reading somewhere that the normal injection set up will compensate up to 3,000 metres. Cheers, Del Quote Link to comment Share on other sites More sharing options...
carlosbeldia Posted November 29, 2012 Share Posted November 29, 2012 Argentinians are used to drive on the Puna, really near 5000 most of them in 300's with no problems. Toyotas have problem at that altitude, Land Rovers don't. My TD5 have been over 4500 m with no issues at all. Quote Link to comment Share on other sites More sharing options...
carlosbeldia Posted November 29, 2012 Share Posted November 29, 2012 Here are two reports well gone 5000 meters: 5500 and 5850 in 300's with no problems, only the obvius diminish in horsepower and torque... http://landroverclub.com.ar/viewtopic.php?t=103612&highlight=altitud Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted November 29, 2012 Share Posted November 29, 2012 I would not dick about with the fuel pump unless you know what you're doing and how to reset it, reduced performance is preferable to pump or engine breakage miles from home.
