What did you do with your Grenadier today?

[Znarfgh]

Just fitted the Falken Wildpeak AT4s to the beast. A Falken 265/70/R17 in the AT4s looks like I went to a 275 or maybe even a 285.

Still plenty of tread on the "old" KO2's. Three of which are being moved across to my Stockman Pod trailer. The fourth was fitted to a spare rim I bought for the IG, as a second spare.

I do not see the point of buying new tyres for the trailer when there is plenty of tread still on the KO2s. So I put some milasge on the KO2s and moved them across.

It came down to KO3s, AT4s and Cooper ST Maxx (which I used for many years on the Patrol without a single puncture). Coopers was knocked out first, then the KO3s.

The steering is lighter but that may just be the new tyres with a slick surface. I go for a longer drive this afternoon after I correct the tyre pressures.

EDIT: torquing of wheel nuts checked. Tyre air pressures fixed. I suspect the tyre shops gauge needs calibration.

I thought you had a Vista RV.

I'll be interested to see how the Falkens perform, that was probably going to be my choice as a replacement. That or General Grabber.

Do General Grabber have the correct XL version that we have on the KO2's? I had GB's on previous vehicle and found them to work perfect for my needs, but it was lighter vehicle

I only did a cursory look at their website but thought they have. I always ran my Discoverys on GB and they were the correct XL rating.

The Prancing Camel urns for the mountains.

Thanks Brandtnm! These stickers are incredible.

 

[LazarusTheGrenny]

Fantastic combo with the Supra shifter and Grenadier USA transfer case knob. The only possible improvement would be for the shift pattern in the transfer case knob to be painted white.

I painted my black anodized T-case knob with a ultra-fine paint pen from amazon, 2 careful coats and it came out great

 

[TheDocAUS]

I thought you had a Vista RV.

I do, it is fitted with KO2 tyres the same as I took off the IG. Now both the van and the older pod trailer are using the same tyre - KO2s. The pod trailer is just a fancy offroad box trailer, not a van.

The IG now has Falken AT4s. However, the IG's spare tyres are still KO2s (but I now have 2 spares for remote travel).

In short, 3 of the "old" KO2's went to the pod trailer, one became the second spare for the IG (I already had a spare steel rim).

Tyre sizes are now the same across all three.

Very well so far, but early days.

Thanks for the information. I’ve sent an email to Rohan asking for the relevant part numbers. I’ll post those once I get a response.

Love the build so far @KristinaM !

RE: GrenX Snorkel: (updated this post with photos of the Donaldson filter)

I've ordered and received the GrenX aluminum snorkel through Rohan, and Rohan was incredibly helpful through the whole process. It took quite some time to receive the kit from Aus to the west coast of the US. I ordered in June and got the kit in early October of this year. Hoping to install in the coming days and will take photos and video of the install process and final product, will share when complete.

Reason for the extended lead time: production time which is listed on the product page and finding a suitable importation clearance agent. We ended up going with DHL from Melbourne to LAX.

Extra-credit FILTER: as far as filter is concerned: I purchased a Donaldson from Volant. It's the filter for the 2.3/2.7L Ford Ecoboost intake kit that they sell for the Ford Bronco, which is roughly in the same CFM requirement range for airflow from the engine (the 2.7L Twin Turbo V6 in particular, running much higher boost pressures than the 3.0L B58 in our Grenadiers), AND will fit into the GrenX sealed air box. These are not washable filters, but rather long life and with a pre-filter and the sealed snorkel, I'm sure the filter will last quite some mileage.

PN Filter: 61509 (Volant/Donaldson)
PN Pre-Filter: 51920 (Volant/Donaldson)

NOTE: this filter change is likely completely unnecessary, it's simply my OCD and experimentation playing into obsession, and Donaldson is largely the king of filter technology for heavy equipment.

These are a little bit to fiddle with to squeeze into the GrenX aluminum sealed air box, but they do fit with clearance for airflow. The main thing is you'll need to align the sealing rings with 4” rubber filter flange with the adapter rings that come with the Uni-Filter that GrenX ships with, to fit properly on the internal plastic intake ducting. It is serviceable in-situ within the engine bay, thanks to the large top opening of the air-box. Aesthetics fit the utilitarian-industrial chic of the Grenny, that nearly nobody will ever notice.

Will update with how this filter performs post install.

Got a response - The “recommended” pod filter appears to be a Uni Filter Australia CP1 85/140 ( Custom Induction Pod ). I’ve ordered another as a spare.

Concerning my other question - This airbox uses a ball valve for the drain which is great.

The AUS => US shipping timeline is quite interesting. I ordered mine a little over a week ago and ( …tariffs / duties / UPS being a pain and section 232 forms be damned… ) I should receive it later this week.

Interesting that is not the original filter used. The are two other models you see on the GrenX website. Looks like some R&D is going on.

The customized diesel air-box is still being made. Expected release before Christmas. I drove Rohan's car which had the final diesel prototype air-box fitted.

Indeed. I’m also curious if the pre-filter he’s working on is the “PRECLEAN 67” part featured on the New Releases page of Uni Filter Australia.

There is also a screw on pre air filter for the GrenX snorkel that looks like the OEM snorkel. So Rohan told me. I have not seen a prototype.

Unscrew the 4 screws on the snorkel cover, insert filter and holder, screw the four screws back in. So the Uni filter will be sandwiched between the grille and the snorkel head opening.

What have I done to my Grenadier today - Hmm… Quite a bit actually:

More ( snorkel, sealed airbox, diff breathers, REDARC electronic brake controller plus some “minor” items… ) to come as well.

Looks amazing. With the Silenus how accessible is it from the back seats ? Does the 2 section floor allow you to get in from that angle ?

I have a full drawer system in the back that I want to keep so would need to get into it from the rear passenger doors or ladder……. I want to keep the back seats

THREAD ON SEALED SNORKELS

I have started a thread on sealed snorkels here, to stop cluttering up this thread with too much detail.

Now I need to find that sealed snorkel from the EU I saw last week.

The three models from the Australian based GrenX are already listed.

We’ve found the Silenus RTT pretty trivial to access directly from the ( folded ) back seats or through the rear doors depending upon how stuff is packed at that moment. We also have a custom cut phenolic resin panel ( for sitting or standing ) which sits on top of the Goose Gear CampKitchen.

Weight savings, extreme portability, and the possibility of another traveler were the primary motivations for keeping the rear bench seat.
The current bench seat deletes ( Buzz Overland and Goose Gear for instance ) are substantially heavier when built out. I also dislike having water tanks and filtration etc. in a fixed position within the car since you never know where you might want to pull water etc. from. This stuff is also a significant pain whenever it breaks. …To each their own I suppose.

As I said in the dedicated snorkel thread - I suspect the cloth based filter(s) were used to get increased airflow and possibly HP - likely at the cost of reduced filtration.

GrenX are working on some projects where this is relevant - stay tuned.

What a difference 25 Dollaroos have made to my centre console box - good quality on the face of it.
