I'm afraid I don't know anything about the new kit so I can't comment

nice one lads. The scuba tanks sounds like a viable option if I cant find a suitable compressor. very viable.
Winchman yes, that why I was thinking to start afresh with a new valve block and controller, there are plenty of options nowadays and you would have to image they would be more reliable.
The truck air-brake suspensions, I looked at them for a while, thinking the conrods and other internals would be meatier on them.
I did find the following wabco model that is rated to 18 bar / 260 psi
Wabco spec sheet
So you could prob push that a decent bit further? I would like to be able to search on that website using pressure as a search term, but so far have been unsucessful.

I have part of a discovery air suspension system recycled and used as air assisters on a leaf sprung vehicle

Fini 30 bar compressor
https://www.fps-compressors.co.uk/bk_113-28bar.html
Makita also make a 400psi high pressure nailer compressor, model AC310H. It aint cheap though, its a recent product

Really easy. It's a compressor, an air tank, 4 sensors, a valve block, 4 air bags and an ECU.
All parts are cheap and easily available or are rebuildable.
The usual issues with Land Rover air suspension is people not replacing bags when they need replacing, then the compressor goes then someone tells them it will be a really good idea to put coils in.
P38 suspension isn't best but it's not that complicated and you can buy o ring kits for valve blocks.
Personally I'd be surprised if you get enough inrush speed to hop a Range Rover, the other thing to remember is the air bag on them has the shock strut going through the middle so those bags listed just won't work without a redesign of the suspension unless of course you don't plan on driving it.
There are far more things to be concerned about on a P38 than it's air suspension but they are a great car to drive. I had 4.6HSE and it would do 18mpg even ragging it.
The ones that jump really high run hydraulics and even those will often burn out a pump after a few goes because they are running them way harder than they were designed to do. The Cutlass seems to be the go to car for that jumping scene

Airbags are separate to shocks on p38s. I think later l322/l302 have combined shock and spring.
Yes you are correct, I just checked a picture and I had got that wrong.

Re the sping / shock setup, phew!
Taking delivery of the car tomorrow. Will have a good nose around the suspension. Dying to see how strong the upper spring seats are. For the moment I'm going to get the O-rings and fix the air suspension, then over the next while gather the parts to make it jump a wee bit.
Have been chatting to the guy who built the car below on facebook, he is availablke to offer advice, which is a result for me.
On the car below he ran 1 inch hydraulic hose. At 800psi he can make it jump 8 feet or so, but at 200psi it would jump a foot, which is all I am looking for.
From the creator: 'D size special bottle holds 350Bar and regs down to the two tanks at up to 1200 psi, ran 650 psi most of the time'
So there is a balance there somewhere that i need to find, between *practicality* (lol), hose size, airbag ports, valve sizes and pressure.

Hi all. I spent 2 weeks laking a bracket. A bracket. My OCD is getting worse. This project is likely to take me to the end of time. I would like to thank anyone reading for humoring me.
This is that little bracket that couldnt:
So I had to go at it. No need to explain to you guys the process, just going to add pics.
Cardboard shims for the last word in precision
It lifted slightly, no matter that I was careful putting heat into it.
Not so much that it will matter though.
mig welder ran out of gas at this point I think
Its not perfect. But I had to stop.

I spent some cash money on hydraulic hoses. This is a sanden compressor I had left over from another project. Im going to pump it full of grease and demand 180-ish PSI from it.
Also, the following has become clear: I dont need massive PSI. What I need is very large air-lines and valves, with the valves located right next to the air springs.
In this setup the air-lines act as an air resevoir, so when a valve is opened, a large quantity of air fills the air-spring instantly, making the car move.
This information is from people hwo have built similar cars. It's actually an interesting story; Guy built a car and used oxygen or nitrogen cylinders. He built it with massive lines, 7/8th or something.
Later on he found that the car would still get into the air using only 150 psi, because his lines were so big.
Valves right next to the air-springs, air-lines acting as tanks:
