Dear Dune Surfers! @Gertjan @Jaro Tuzinsky @Waqas Parvez @Mario Cornejo @DP1011 @ASAD. @Benjamin @Chris Wing @Naveen Raj @Krishna R.. Thankyou all for joining and giving an overwhelming response.. slots filled in less than 20 seconds!.. we do have @Vaibhav waitlisted for his first drive for the week along with @Bjoern and @Mohamad Anwer who are looking to extend their fun on the weekend. I request all to update your rsvp in case their are any chances of a dropout from the drive. Please ensure your machines are in good condition. i will update the drive plan and unveil a surprise element shortly . stay tuned!

What a lovely Drive that was yesterday. Thank you all dear friends for coming and revealing together one of the dozens of mysteries of Lisaili😄 . Looking at my previous tracks no one is alike not even close , that’s why they call us the explorers , desert wanderers and dune surfers 🏄‍♀️. @Looper in the second lead never missed a step and kept the convoy safe on track behind you. Extraordinary as usual 👍 @Stumpy Paj last minute joiner, pleasure, and in fact you managed it among the wrangler pack disguised in your elegant beast . No issue at all . 👍thanks for coming 🙏 @Marketa Dobesova “ v modra wrangler “😉 in the blue or yellow as Deepak mentioned your skill and attention is what matter . You drive fantastic excellent progress through Carnity ladder 👍 @DP1011 as always having you in any drive is so joyful and helpful . Thanks for the milky sweets 🙏 @Ignacio Quindós driving behind Deepak and in-front of Ale , with respect to your undoubted skills , gave you freedom and a treat to capture some beautiful pictures thanks 🙏 last but not least many thanks for @Ale Vallecchi who made sure that all cars are complete when we crossed the barmuda triangle 😉 . Pleasure to see you my friend after such a long time 🙏 please take care till another episode and from now onwards will be night drives . Cheers

Dear @Jona, @Amr Aydin, @Fabien Monleau, @Naveen Raj@Bashar Beasha and hopefully @DP1011, the briefing will be short. Enter the dunes east of the track, follow them West, then North, reach Nagrah, loop around its star dunes, cross the sabkha, re-enter the dunes, aim North once again, cross more dunes, taller and taller, reach the exit. Convoy order: @Fabien Monleau in Second Lead @Bashar Beasha at #3 @Jona at #4 @Amr Aydin at #5 @Naveen Raj in Sweep. Looking forward to seeing you tomorrow. Have a nice evening.

how do i edit the sound out of my videos of my screaming passengers? 😎😜

This is the video from last week's Morning FB+ Drive at Nahel with @M.Seidam, @Zed and @Ishak. Hope you enjoy the video.

Hello every one time to revive this post and keep it dynamic and useful so it can be a reference to all of us to share experience and discuss . here we go yesterday I was pulled from my crest from back . We all talk about front heavy or back heavy and according to this comes the pull direction . Sounds logical of course . The question is what does it mean which side is heavy ? see below and let me know how you think of it . ( I wish I could have more picture from the side and the front )

Thank you, @M.Seidam, for organizing such a beautiful trip in the middle of the week 🙏. Really a nice relax in the middle of the work 🙌. It was fun and pleasure driving with you all! @Ale Vallecchi, shame I cannot join your upcoming weekend drive as I am doing Wadi crossing in Fujairah, but I am sure you will organize another trip soon ☺️🙏. Look forward to driving with such excellent drivers soon again !

I would like to share my experience with my own car which I know exactly where its center of gravity lies , so should every one know his own car point of center of gravity. From the clip it looks like the car is inclined toward the other side the slip side . However with close observation ( that’s why always get out of your car when feasible and safe and look around ) the center of gravity didn’t cross the crest and the crest acted like a ( speed bump ) to overcome forward. Consequently it would be easier to reverse it down than to overcome it because the center of gravity is at the hard side of the crest irrespective of how the apparent looking of the car. now as such and without shovelling the backward gentle stretch or pull as you see in the clip is far easier than if we have tried from in front . To make this more clear . Let’s imagine if we have shovelled properly creating the V channel just clearing the ( speed pump ) this means we moved the center of gravity passed the crest toward the slip side or at least no speed pump or crest to over come and then the forward movement will bring it down As this is the most common scenario we encounter . see below please from another Carnity drive last winter in lisaili Now look closely the little difference with great impact after shovelling . I didn’t even need to press the gas just lifting off the brake and here we go

Self Recovery masterclass by @M.Seidam with @Ishak (360 video)

Very nice idea @Looper to have one dedicated place to have all drive videos. Easy to enjoy while having a break and handy to refer back to in the future. Good thinking.

Dear @Jona, @Amr Aydin, @Fabien Monleau, @Bashar Beasha and hopefully @DP1011, this is the "classic" Nahil deflation point: Nahil Deflation Point https://maps.app.goo.gl/etEMS1sU4Y9y3Cvi6 Short drive's briefing to follow. Thanks

I am so sorry bro, family health issues, must remain behind this weekend, although I was really excited to re do the fun drive we had but without any unfortunate accidents 😔 😟 🙁 Enjoy 😉 with the great team 💙 😎

I appreciate your maturity to understand the intent… thanks @Naveen Raj.. you can remove your rsvp yourself from the calendar “going “ tab…

@GauravSoni I’m confirmed for this weekend car has been double checked all is good

Noted @GauravSoni. You can remove my RSVP to give chance for the next waitlist member.

Surprise Element is always split convoy, so hope is not lost for the WaitListers... in that case, i'll add myself to WL 😁

There are always next time inshallah dear @Pranjal Varsani1 we missed you yesterday.

As most of you Dakar drivers would know the road noise in the cabin of the Pajero gets up there at times, has anyone put in sound deadening. What areas had the most effect. I have done the floor and will start the rear 1/4 panels next. Plan is to do the doors last. The rear section had no sound proofing at all, that seams to have made the biggest difference so far, with the passenger foot well close behind

In this topic i am trying to go a little bit deeper into the whole concept of tyre sizes for offroading. Often, we start off with the stock 31inch tyres and find ourselves upgrading to a 32-33- or even 35 and more inch tyres, which might give benefits, or not ? First of all, we need to split into two categories: 1. Offroading in sand/dunes aka dune bashing. 2. Offroading in mountains aka rock crawling or wadi bashing. It is important not to confuse both, and they are almost opposite in terms of wheel size and i will explain this further below. We will not be discussing the fuel economy in relation of tyre size in below topic, nor the effects of the odometer reading, but rather focus on the performance aspect Category 1: Offroading in the sand/dunes What are the key parameters that determine the performance for driving in the dunes ? * Tyre weight (relation with overall size). * Surface area of each tyre on the sand when deflated. * Rolling Resistance * Tyre profile (aggressive knobby vs smooth HT tyre). Looking at above parameters, we would conclude that we are looking for a light tyre. The tyre profile in sand is not so important while driving but deflation is critical, and an AT tyre can be deflated further down safely compared to an HT tyre. We also noticed big differences during self recoveries on a smooth HT profile tyre vs a tyre with some moderate profile (AT tyres). Going for larger tyres results in higher weight on the axles, BUT seems to help with the contact patch area which is a good thing. So there is a balance that we are trying to strike. As a result of that you will see most offroaders in the dunes using similar tyres from the stock 31" to about 33" but not often 35" or more because of the negative effects that go along with that. (see re-gearing further down this topic). Category 2: Offroading in the mountains What are the key parameters that determine the performance for driving in the mountains ? * Surface area of each tyre on the rocks when deflated. * Tyre profile: AT Tyre is needed (HT tyre is not suitable for regular offroading in the mountains). * Ground clearance. As you can see, the key parameters for driving in the mountains are somewhat different because during rock-crawling you will be mostly in Low gearing and won't be needing the full top-end horsepower of your 4x4. The focus is more on using good torque and getting good clearance to overcome those boulders and other obstacles. As a result of that, bigger tyres would be performing better, simply due to the fact that you will win ground clearance without having to lift your 4x4, and the extra surface area of those tyres will give you better grip as well. And this is the main reason why we see so many Jeeps and Bronco's in the US on 35"-37" tyres crawling over boulders Re-Gearing: What's that all about ? source: https://www.4-wheeling-in-western-australia.com/differential-gear-ratio.html The differential gear ratio on a stock standard 4x4, are made to suit the tire diameter which the vehicle is originally came with. Using bigger diameter wheels/tires with stock ratios will cause more wear and tear on clutch, driveline and engine. Low range gear will also suffer as 1st gear low will now roll too fast as the tires are bigger, this becomes a problem when descending steep hills and climbing rocks and logs. Example: a stock 2005+ Toyota Hilux has 29 inch wheels/tires and fitting 33 inch rubber is quite bigger (4 inches in diameter bigger) this will cause the engine and entire driveline more stress and more power is then required due to the larger rolling resistance. The final gear ratio is suited for 29 inch, this ratio in this particular case is 3:5, referring to a chart it will state the same (29' recommended ratio is 3:5) and looking at 33 inch diameter the chart will recommend 4:1. Going by the chart any higher will make the 4x4 rev too much at highway speeds causing poor fuel economy. Changing the crown wheel and pinion is how the ratio is modified. Basically installing a new or reconditioned crown wheel and pinion with the recommended ratio will bring the 4wd driveline back to stock specification rpm and fuel usage. Once differential gear ratio mod is done the vehicle will regain its 1st gear low range and take off in high range will be improved or even back to stock. This chart is an approximate tyre size to differential gear ratio; it’s based on an RPM at 105 km/h (65 mph) and 4th gear on a manual transmission or 3rd gear on an automatic gear box (1:1 gear ratio). This is only a guide to get a general idea of which ratios would suit the vehicle in question. To get an accurate RPM the following steps and formula will give an accurate answer: Take a drive and record the rpm at 105 km/h (65 mph), the next step is to work out what the current ratios are in the vehicle. This can be revealed by calling the manufacturer or even calling a differential repairer giving him/her the Vehicle Identification Number, also known as VIN. Once all this information is known use the following formula to get the accurate differential gear ratio for the larger tires: Example: The rpm is 2806 at 105 km/h (65 mph), the current tires are 29 inch, the factory ratio is 3.73 and the new size upgraded tires are 33 inch. RPM: 2806 Stock tires: 29 inch Stock ratio: 3.727 New Tyre size: 33 inch 2806 = 65 x 3.727 x 336 / 29 (rpm = mph (not km/h) x diff ratio x 336 / tire size) Now the correct rpm is known for the vehicle (2806), the next step is working out what ratios are available for the vehicle, some makes and models won’t have as many choices as others. Say the following 3 ratios are available 3.909, 4.100 & 4.88. The new tire size wanting to be fitted is 33 inch and the rpm needs to be a close to the 2806 as possible in order to keep it to stock specs. Just a quick scan at the differential gear ratio chart it’s obvious that a ratio of 3.909 is too low at 2587 rpm, ratio of 4.88 is too high at 3230 rpm. But looking at 4.10 with the rpm at 2713 is the closest to 2809 stock rpm. New Specs: RPM: 2713 New tires: 33 inch New ratio: 4.10 Please share your experiences / feedback !

@Rajesh NG, it's juts been updated. All good. Thanks for understanding

Hello Ale, I just got promoted to Fewbie mate, so i am eligible for this drive. But nevertheless, i was anyways going to withdraw my rsvp as i have some work commitments Saturday morning. Drive safe and i will join you in another drive soon.

Hello @FERNANDO SYRIO. I have just posted the meeting and deflation point Dropped pin https://maps.app.goo.gl/aeqCoTn97u8ZbjZv7 Thanks for asking.

@Naveen Raj I noticed that you have changed your ride.. can u let me know how many FB + / IM drives have u completed with your new ride?

Sorry @Frederic I wrongly compared 1st Gear 4Lo with 1st Gear 4Hi, should be 4th Gear 4Lo (cos my transmission is 4-speed) and 1st Gear 4 Hi., So the new calculation D. 4Lo Crawl Ratio on 4th Gear 4Lo = 0.75 4th Gear x 3.12 4Lo x 4.88 front & rear diff = 11.42 on 4th Gear 4Low E. 4Lo Crawl Ratio on 3rd Gear 4Lo = 1.00 3rd Gear x 3.12 4Lo x 4.88 front & rear diff = 15.23 on 4th Gear 4Low Yes you're right, my 3rd Gear 4Lo (point E) will now be similar to my 1st Gear 4Hi (point C) once I upgrade to 10% underdrive gear on the transfer case 😁

So let's calculate that: A. 4Lo Crawl Ratio on 1st Gear 4Lo My 4Lo ratio is 3.12 : 1, so if i hit 1st Gear on 4Lo (1st gear ratio is 2.80), my Crawl Ratio will be 👇🏻 [ Transmission Ratio of Current Gearstick x Transfer Case Ratio x Axle Ratio ] = 2.80 x 3.12 x 4.88 = 42.63 on 1st Gear 4Lo B. 4Hi Crawl Ratio on 1st Gear 4H Current 4H ratio is 1:1, so if I hit 1st Gear on 4Hi my Crawl Ratio will be 👇🏻 = 2.80 x 1 x 4.88 = 13.66 on 1st Gear 4Hi C. Future project, gear reduction of 4H by 10% This would mean my axle ratio is increased by 10%, so 4.88 + (10% of 4.88) becomes 5.37 = 2.80 1st Gear x 1 4Hi x 5.37 increased = 15.04 on 1st Gear 4Hi So Mr @Frederic from point A, B, C, no my 4Hi won't be any close to 4Lo, it will actually just be 10% more torque than current 4H. Because of my 3.12 : 1 4Lo ratio, my 4L and 4H are like sand & sky apart (42 vs 13 crawl ratio) 😄

Yes @DP1011. We'll meet just off the tarmac. Will poWill he meeting point ASAP. Hope to see you.

Let’s bring the waitlist in, all are great drivers who would mostly have fun at the back😂

Would that basically turn your 4H into a semi-4Lo ?

Will do @Ishak, but in which direction? Towards going or out of the drive😅

@Hisham Masaad I was sleepy when unintentionally pressed the manage button 😅. Please kick me out.

Hi @Ale Vallecchi Is the start point going to be somewhere in Nahil ? ( I am hopeful of making it to this one 🤞)

Doc @M.Seidam - Was nice lovely drive out in middle of the week and the convoy strength speaks about how brilliant everyone drove ! I couldn't differentiate between anyone on the drive irrespective of their experience specially @Stumpy Paj @Marketa Dobesova @Ignacio Quindós !! Zero refusals - Speaks about the drive and No fish tailing- At some technical patches I was waiting to hear refusal but was pleasantly disappointed ! @Looper Perfect SL haha - what more can I say and @Ale Vallecchi As I said- my first drive with you as Lead in reverse order ! Always pleasure to see you! See you all soon in Desert !

Beautiful views today following the lead of @M.Seidam. An impressive set of experienced drivers, with 4 out of 7 being either leaders or support team members. Luckily I drove behind @DP1011 who showed me the way… Many thanks to @M.Seidamfor organizing a drive on a weekday. It gave me the opportunity to unwind a little before my busy weekend. @Looper and @Ale Vallecchi it’s always a pleasure to have you in the convoy. @Marketa Dobesova @Stumpy Paj it was nice to drive with you again. The doctor under the spell of Sauron’s eye… An awesome sunset today… Rest of the images in the gallery. Have a lovely weekend!!

I changed my front diff & rear diff 4.30 gear ratio to 4.88 and I like it: both the torque and the speedometer correction since my tires are 285/70/17 (33") . Since I like it so much for sand use, for my next project I'm ordering UnderDrive Gear for my Transfer Case. Because my LC100 is Full Time 4WD, after transmission/gearbox it goes to Transfer Case before going to front & rear diffs. By modifying the Transfer Case gear, I'm re-gearing without changing both front & rear diffs (actually should have done this but parts was not available at the time). When I change the Transfer Case Output Gear, the output of front & rear diffs will be increased from 4.88 to 5.29, which will give me more torque. The only downside to regearing is high RPMs and worse fuel mileage, but hey I can tow trucks and mileage for V8 sucks anyways 😂 Link for underdrive gear example: https://cruiserteq.com/sumo-gear-land-cruiser-transfer-case-10-underdrive-gear-set-fits-8x-100-series

Done this, the reason I bash my Jeep more now than my LC100, cos the car feels a bit more Lexus quiet now 😂 Rear Wheel Wells, Front Firewall, Front Doors and Roof Liner are the best places to reduce outside noise to the driver. I actually created a Word doc for the garage with a list of example applications, lemme see if I can upload that here...

At 120, on the same road at the same time of day I was getting 82-85db today after the insulation I got a average of 71 -74db. definite improvement, can still hear noise from rear wheel wells so that’s on the list next.

Possibly I will over the tunnel and the fire wall, will see what sort of difference I get with this first. Just doing the rear cabin has made a big difference

Mia is ready 😎👍
