Heavy Duty Radiator

[Napalm00]

I highly, highly doubt it. Everyone is welcome to post up photos and videos. It's not just the couple-times-a-year, but I wheel more frequently than most anyone here as well.

In the last week, I've snapped a rear axle shaft, wheeled twice for 8+ hours both times. Drove it home in 4-High. I see a lot of trucks get built to high heaven, and used less than a quarter of the time mine does.

Again... bold claims are easy to shoot down with ammo. Have at it.

Lol ok

I have a 2.8 l block overbored from a 200 TDI with 2.8 crank, 300tdi head, 120% over injectors, 13mm pump with custom lift plate and larger diameter injector lines. Arp head studs running 40lbs of boost on a 7cm he221w turbo with 3in exhaust coming out of the hood. Defender timing case and top mount turbo. Running a stock location 300tdi style intercooler. 1.4 tcsae on stock gears with 35 swampers.

My truck can maintain a 15% grade at 120 degrees ambient temp at 75mph. I've recently been running the mint400 course back parump circuit. I daily the truck here in Las Vegas, its all about the tune. I'm running a Chinese copy of the allisport 300 rad.

So yea I'd say I've got more engine and harder work. When I had a front mount intercooler I would get temp creep on the highway.

Ah and the block has approx 1.2 million miles on it and I don't consider myself a hard wheeler compared to half the nuts on this board .

That local construction site trail looks pretty intense.

You seem.... Cool. Or "intense."

Cart meet horse.

Maybe there's some confusion. I drive mine a lot on the roads as well, but I was talking about off-road.

No confusion. I could drive mine on road and out wheel yours easily. You asked who was more hardcore. I am

Your truck seems mostly stock and frankly it's easy to wheel something that you can't break because you don't have enough juice.

Dude! "lol"

Yeah totally. No photos of you on the Mint course shredding it? It's all good the head studs sound super cool though. As does the smokestack out of the... uh, hood. Can we get some videos of you running some wash?

Man. You a pineapple guy? That tracks.

I think there's a deeper discussion here about conservation and the impact that hardcore wheelers like Gerken have on the environment. Cross-axled, open diff wheelspin, especially on baby sized staircases that a Subaru could walk up, is not reflective of the Tread Lightly® pact we all swore as Land Rover owners. Personally, I've been slowly building confidence by going to my local dealer once a month and practicing my offroad driving skills, and once I finally take my Land Rover to the trails I can do it with a clear conscious and know that, unlike Gerken, my actions aren't contributing to the destruction of my local county-maintained bike and walking paths.

If you don't think this is hardcore, you clearly don't get it.

I think reasonably air tight is good enough. The Ron Davis radiators I use just have a simple foam strip around the perimeter to help seal, but there are air gaps present. Ideally you want all of the air entering the core to exit through the fans, but some bleed is probably inconsequential. Can't offer much on the theory of spacing, but on these the face of the fan hub is roughly 1.75" from the core.

Super helpful, thank you!

Is this thread still about radiators??

I think it's about weiners.

You beat me to it...

Damn, that came out differently than i meant too.

 

[Napalm00]

That's the joke 🤣

 

[Ash]

There’s no way anyone on this forum beats on their weiner as hard as @Z.G does

This engine sounds awesome! Can you get to this spec with a 2.8 crate motor to start and add in arp and bigger turbo. Or are there a zillion other bits n bobs to run that psi?

FWIW, I recycled the fans that my Allisport “piece of junk” came with and put them with the stock RN radiator. Currently running a 190 deg thermostat but I’m thinking of dropping that down to 180 as most of my miles are off road.
Pulling more air underhood is one part of the puzzle. The other is to help air to escape,

 

[gerken]

I thought hardcore was about stud bolts and driving up inclines?

Ash doesn't want to hurt the environment, so diesels are out of the question too. Where oh where shall we go next?!?

Shucks FloridaGuy™, you are THE MAN. When you're finished building a truck that'll never get used, be finished, or see anything muddy, tow your subie up here so you can smash it up. It'll be a hit at the next "lies around a campfire."

Anyway, tighten up those studs and be sure to datalog and track your speed and temps in Tennessee and Kentucky. That's some impressive stuff there.

 

[abraded]

But do you wheel as hard as this guy?

I will say that the hardest trails I've run don't put a ton of strain on the cooling system--much less than pulling a mountain pass in triple digit temps.

Obviously you’re not an off road god like Gerken. He did a whole 8 hours off road and broke a stock Salisbury axle shaft. Hard to contemplate that level of badassery
