So far you are the only WL and at the top of that list. 2 Link to comment Share on other sites More sharing options...
Christopher Assal Posted June 21, 2021 Report Share Posted June 21, 2021 At least 2500 is more then the. 1500 I experienced 😂👍🏾🎉🎉 3 Link to comment Share on other sites More sharing options...
Niki Posted June 21, 2021 Report Share Posted June 21, 2021 @Wrangeld sad to say I’ll be dropping out of the drive! 😢 … this was a drive I have been wanting to join more than most and gutted to miss out. I am likely to be on pause for weekend off-roading for a while however will keep an eye out as you develop these challenging drives ongoing and cannot wait to join a future trip! Have a fun ride all .. 1 Link to comment Share on other sites More sharing options...
Popular Post Wrangeld Posted June 22, 2021 Author Popular Post Report Share Posted June 22, 2021 Dear DesernautsUAE, I cannot believe it's Tuesday already. It seems truly, as if the weeks are folding one into the other in a blur. Before the drive Friday, I wanted to develop the thinking just a bit more behind the limited RPM. My aim is to find a way to have a truly exciting drive while maintaining a limited rev range. To achieve that we are all going to have to see if we can learn how to climb using different techniques, slide slope and criss-cross using drive skill alone. When we started driving in the sand, it's likely that the drive lead told you to put your foot to the floor - that was because most are shy to use the power to start with: and then it becomes a sort of addiction, because we can often power our way out of trouble. The more experience we get, the more we try to finesse our style so that it looks graceful and as if we are simply floating across the sand. I watch long distance runners who glide majestically along the tarmac, not seeming to breathe (where I would be gasping for breath after 10 meters), cyclists that power their cycles up mountains with barely a sway in their movement and the fastest laps on an F1 Grand Prix are always the ones that when you watch them the car does not really look like it's going that fast. That's how I want to feel when I am in the sand, so it looks effortless, like the car is gliding across the sand, as if the car simply floats above the ground. Will it work? I have no idea. This is a bit of an experiment. I've driven through the desert on very low revs to recover stricken cars where they cannot be pushed, but never lead with the express purpose of leading a convoy to achieve the same. I think it's going to be fun trying. And if it all turns out to be too much ... See you soon in the sand. 6 3 2 1 Link to comment Share on other sites More sharing options...

I think that the vision is inspiring, surely for all who have decided to attend this drive, what I personally would find useful in preparation to the drive is a how-to oriented post. E.g. if you do this to approach a criss-cross, then you will need less power etc. Also, as an idea, we could design part of the drive with A/B approach comparison. E.g. for instance you could show us and why not us practicing then, two approaches to the climb or even the different picking different lines makes on the necessary effort (e.g. reading the dunes better). Just food for thought that I dare to suggest as I see you also nudging the team and invite to the thinking. I imagine not everything is possible or easy with such a long convoy. An Engineering note (told ya I am one): % of Max Torque and Power at 2,500 rpm is quite different by engine...so that limit will mean different challenges to different drivers... but the spirit of dune gliding is what I guess the most important thing is. Looking forward ! I really like this engineering approach @PaoloMaraziti and will try to incorporate a few of these theoretical how to ideas in these posts. The A/B testing idea is also fantastic as long as the convoy is OK with that stopping and starting (maybe better suited for a masterclass where we can take the time to experiment?) In essence, yes, this is about how to get your car to glide and run smoothly, but also how can you approach an obstacle in a different way (as you mention). Is there a way to build momentum to cross a high dune by circling round and building up momentum instead of powering up the dune? What approach angle do you take to criss-cross that might be different with different power at your disposal? Also you are of course correct. 2500RPM in a V8 Hemi is going to look quite different to 2500RPM in a Suzuki Jimny. If the drivers of the larger vehicles see no difference (which maybe they will not) they can always take the challenge and lower their RPM to experience that feeling. Once other addition to my earlier post. We will be looking into how to drive through technical dunes as well. If there is an area of expertise where finesse is more important than power, it's in getting through the technical dunes ... 2 Link to comment Share on other sites More sharing options...
M.Seidam Posted June 22, 2021 Report Share Posted June 22, 2021 Hi Richard, if you allow me to post here in this drive post 🙏 I read all the above mentioned info , the context and idea is nice I have been experimenting different inputs to My Xterra , 2 tons V6 with almost 270 HP . all the time in the different attempts ( usually 2 to 3 ) the outcome was different e.g feya ( maybe not ideal spot ) . I tried to be constant after reaching ground momentum just before take off in many attempt I had to navigate slightly the imaginary path trying not to alter but half way I had to shift to gear 1 to keep the RPM same or else just before hitting 1000 RPM immediately I exit down. What I am trying to say is there are many factors is governing to what some one is intended to accomplish. Terrain , softness , slope angle , vehicle type , drivers skills ( drivers factors / vehicle factors / terrain factors ) 2 Link to comment Share on other sites More sharing options...

Terrain , softness , slope angle , vehicle type , drivers skills ( drivers factors / vehicle factors / terrain factors ) @M.Seidam you're always welcome to post. I think we all accept the basic premise that different factors will influence each drive, dune, day etc. We are not necessarily aiming for consistency in this activity - repeatability is a science lab concept often far removed from the reality of the situation. The aim is to understand how much control and capability we can squeeze out of the self imposed limits we apply. While I have done recovery drives where we set (actually a) Lower limit on the RPM I have never consciously sought to self limit on the RPM and see what can still be achieved. I am convinced of 2 things. 1. We are going to learn something about our cars that we did not know before this. 2. We will learn a lot about our normal driving style - because by making this change we will find how this differs (or not) from how we drive normally 1 1 1 Link to comment Share on other sites More sharing options...

Niki Posted June 22, 2021 Report Share Posted June 22, 2021 9 hours ago, PaoloMaraziti said: all ok @Niki, it’s a bummer not to drive together … following your (and many more) advice , my FJ is wearing new lighter shoes and this is is going to be the baptisms of fire, inshallah… I’d have love to share my experience with you and again thanks for the help in the sand last weekend @PaoloMaraziti i was really looking forward to the drive and reading the thread and Richard's summary I can only hope for a repeat ride in the future. All is good however I am required for the family duties which i must prioritize - truly appreciate you checking in! Knowing you are sporting a new pair of shoes - i am even more gutted as would have been a great trip to join together and share experiences. Remember to run the new tires in this week so take a few more highway miles on them ready for Friday (on a recent Extreme drive one of the team had a new set of wheel put on and hadn't run them in which caused a pop out ... plenty time to run them and the seal in this week!) .. i will be monitoring the thread so am keenly waiting for the post ride reports and feedback! Have a super ride and drive with confidence ... your new coopers will make you feel like you have ballet shoes on I may ask to be put on a wait list incase circumstances change later this week however at the moment i will enjoy the ride through you and your report my friend. PS we were all in awe of your Yeti cool box and the glamorous/luxury refreshments you stocked! 1 Link to comment Share on other sites More sharing options...
