Tibus portals

[Tins]

Anybody know anything about these ?

[justinc]

Chook73 has a raft of posts about his experience with them. Not all positive...

[rangieman]

I think learning to run away fast will help[bigwhistle]

[weeds]

I use an engineering shop that would easily be able to knock out maxi-drive portals.....although out of my budget

Not sure if MR (I assume they own the rights) will ever look at making them.

I think NSW is the only state that entertains portals

Have a look at MAER , A polish company . LandRover portals in development

Interesting how anyone with portals questions is always referred to Chook and his dilemmas, no doubt issues there, however it should be noted that Oilworker both on here and here... An expedition truck on portals... | Expedition Portal (https://www.expeditionportal.com/forum/threads/an-expedition-truck-on-portals.37713/), as another example has had no issues nor have many others on other forums.

I can assure you that there are a lot worse conditions out in the big wide world than Australia...

Don't bother if you're going to Qld

But Officer , I'm still running 750-16's & the suspension is standard .

[martnH]

I don't think oilwoeker does the same kind of "offroading? I may be wrong though...


Another option is axle tech. They supply the portal axle to G wagon. maybe you can buy a set and weld the defender brackets on.

Yep debatable but after 270000kms and no faults that is a pretty good advert to me...

[101RRS]

With the exception on oil leaks, I dont have any real issues with portals on my Haflinger - well maybe stability in some circumstances.

Like all modifications there are swings and roundabouts - portals increase clearance but reduce stability - now there are ways around this but the main solution is to be aware of your higher CofG and drive accordingly.

[86mud]

I was lead to believe that Tibus portals were not up to rock crawling - which is where Chook73 had issues. Wheel spinning and a single point of impact seemed to stress load the portal and transfer this stress onto the stub axle. I think there were oil leak issues as well - but this could have been due to type of gasket and/or correct torquing of bolts.

Oilworker give his portals hell, but in a different way - high speed rough roads.

I am always dreaming of portals, but i am not sure how engineering of these will go in QLD. Especially with vehicle mods currently under the spotlight thanks to the QLD police "Operation lift"

That being said, the Patriot Campers 6 Mega Tourer 6x6 sits on Marks Adapters portal boxes and is engineered for road use (on 35" tyres) here in QLD

If MR were to ever fire up production, i'd be seriously considering a set.

[Red90]

Oil workers portals were a different design.

[Tins]

Well, at $21k plus shipping and tax etc you can all forget I asked. Thanks for answering though.

[martnH]

Shame we can not refinance our defenders like investment property

[goingbush]

$21k - thats about what my EV conversion cost , Hmm portals or EV ????. Im glad I went the EV route. Best buy a Bollinger B1 . best of both worlds Portals AND EV .

[scarry]

Don't bother if you're going to Qld

But they didn't say anything about stability control when i bought it[bighmmm]

They recon the next thing they are going to ban is GVM upgrades for all non commercial 4WD's.[biggrin]

So the LC200 soccer mums,with the kids in the car, are going to have to do two trips to the supermarket,instead of one, in case the cops are hiding around the corner[biggrin][biggrin]

12,800 eu. Not sure I want an EV, but that is the cost, when all other costs are factored in, of a 130 Mulgo conversion. I was really only after more clearance, and I reckon the airbag setup like Weeds has would be sufficient for my needs. Heck, 35s would probably do... Oh, I forgot to mention,the conversion also requires new wheels, as Rover wheels don't fit. WTF?

Never heard of it so looked it up. Awesome Bollinger B1 | Bollinger Motors (https://www.bollingermotors.com/)

yep, my names down for one , depending on if the new Defender (Electric ) is to my liking.

[86mud]

yep $21k is just for the portals boxes...you need bigger wheels (Tibus can provide a Hutchinson beadlock with a positive offset) to clear the portal hub and brake caliper combination. Then you need wider flares and possible widening of bullbar etc to satisfy Engineering/State vehicle modification regulations.

it's a headache for sure

gotta be a first in my experience for a manufacturer to quote the number of 2 x 4's and dry wall sheets that can fit in the vehicle as a sales pitch. the other thing i found funny was the wind tunnel for a vertical windscreen box on wheels. As a touring truck, 75 min recharge every 320 kms will make for long days. For local 4wding, why not.

Back to Tibus, Iain's old set are destined for a 120" Alu tray back with an Isuzu under the bonnet. The weight difference between the 2 vehicles will be an interesting exercise in longevity.

[86mud]

I wondered what happened to Ian's set of portals.

I can not remember if the Tibus portals use Defender calipers or something else?

My "understanding" is that original brakes are used. Only the wheels need to be changed.

Not going to get 320k in low range, are you?

[goingbush]

Not going to get 320k in low range, are you?


Would go further in "Low Range" due to electric motor being more efficient at higher rpm and lack of wind resistance , the Bollinger does not really have high / low range just a 2 speed shyncro box on each axle.

[Red90]

Lol. No you use more energy per km off road than on road.

[goingbush]

Not with electric you don't, you know about Regen braking right ?
Use power to go up hill , then it feeds back into the battery going downhill.

Aerodynamic drag is what saps the power on road, that won't even come into play off road.

[Red90]

Yes. I went to engineering school. You use a lot more energy off road per distance travelled. It takes a lot more energy to move the vehicle through the rough terrain. It has nothing to do with the hills.

One example where class room theory does not apply in real world. Maybe if your talking about a quagmire or most of your time is spent spinning the wheels. I have proved it in my Electric LandRover , crawling along at under 30kmh on firm dirt tracks my range is 200 plus km , at 80-100kmh on the road its about 70-80km . for the same battery charge.

[loanrangie]

My old TDI D1 would run on fumes off road if you weren't revving it's guts out.

Take all other factors, such as aerodynamics, out of it, and look at the basics. Imagine your LR did one engine revolution per one wheel revolution in high range ( simplistic, I know ). Now engage low range. Imagine you LR now does one engine revolution to one half of a wheel revolution. Explain to me how the same amount of energy expended will result in further distance travelled. No amount of regenerative braking will make up the shortfall, unless you have invented a perpetual motion device, in which case you would be rich.

You make no mention of which gear range you are in doing this. High/low range was the starting point of this part of this discussion.

[bee utey]

A petrol or diesel engine has substantial internal friction which causes power losses directly increasing with RPM. Electric motors on the other hand have very little internal friction and their efficiency actually increases at higher RPM. The losses are mainly due to magnetic fields reaching saturation in the iron laminations, so double speed half current operation is much better for them.

Not that this has much to do with portals but it's important to get the facts right. [smilebigeye]

[goingbush]

Also no wasted energy in the form of heat lost out the exhaust & radiator , which I understand would be higher in a Internal combustion in Low Range . More waste lower speed . Not the case with electric.

Agreed the argument has nothing to do with portals . my fault.

Great and all that, but still no mention of the premise which sent us down this rabbit hole, which was about efficiency high range v low. Are you saying that electric defies the laws of physics? Or, did you not read prior posts?

[Tins]

Seemingly it has nothing to do with High/Low range either, which was the very thing you chose to argue. Or was it me who was mistaken??

I don't think so: I asked "Not going to get 320k in low range, are you?"

I love that you have done something different. But you cannot prove that your electric LR has a greater range in low range than it does in high. THAT was the argument. That is what you have not answered.

yes John , It will travel a much greater distance in Low Range than High Range. about 3 x
Its bleedingy obvious when you look at the Kwh meter , its hardly draws any current in Low Range compare to choofing along at 60kmh.

High Range 2nd or 3rd gear keeping below 40kmh, will EASILY have about 50% greater range than sitting between 80-100kph too.

Mark French demonstrated this in his Guiness Record crossing of the Simpson Desert in his Electric converted Suzuki 4x4 , He was in Low Range 1st & 2nd gear most of the way ...... to get the most distance per charge.

Did you read this bit of my post:


double speed half current operation

Which implies low range operation does it not? Additional transfer case losses are much smaller than increased engine losses, which electric motors don't have. Anyway, I'm interested which "laws of physics" you're referring to, I'd like to look them up in my textbook collection. [bigsmile1]

Yes as said before on the forum I am very happy with mine expensive yes but no regrets.

[86mud]

Did you have to modify any suspension links?

Any pics?

Cheers

no mods to any suspension is required to fit Tibus portals .
the only requirement that I did that wasn't noted is I had to install a hydroboost or larger master cylinder .
I chose to install the hydroboost which works well .

[86mud]

And how did you go about getting engineering certification and registration (which state are you in)?

[Pateyw]

I am in nsw and no issues with regerstration 7 years now.

[Ranga]

What sort of money did it cost, including shipping and fitting?

[Pateyw]

It's been 7 years now but with portals wheels (6) and hydroboost total cost $23k-24k
installed them myself .
