A custom semi-ladder, semi-spaceframe chassis would allow you to pick some much, much better suspension. For example, pull the subframes off an L322 Rangie and get, strong, modern components.......

This is basically what I have but with Range Rover suspension (coil springs).

Thing is, he needs to use an original and unmodified chassis if he is to avoid an IVA test, which he has no chance of passing with the vehicle described so far.

Please explain why I will not be able to pass the IVA.

Chassis will be fully refurbished, I have a new, unused V12, 27 litre Meteor engine, and will buy a new or refurbished auto transmission.
I will need to meet all other IVA requirements, most of which are common sense and not too onerous.
The engine will not need to meet any emission standards other than a smoke test, due to it's age, which will not be an issue.

I am sure the inspectors will try to fine things to fail the car on but there should be nothing that is not impossible to rectify.

I can't see any particular reason why such a vehicle won't pass an IVA. Yes, a few things will need to be considered during the build, but as this car is getting pretty much built from scratch body work / interior etc, then those things can be sorted fairly easily.

There are an awful lot of cars that are built to pass an IVA, then subtly modified once registered, especially for some of the really silly stuff.........

Why do you think it would not be possible to pass IVA.
Noise would be the difficult bit.

Not with enough silencers Steve.

They may fall off afterwards though....................

My Ultima GTR was 95db with all track day silencers. It moves about 71% air through the engine at WOT compared with the Meteor so a couple of larger silencers should do the trick.

I will need to spend some time reading the IVA regulations but what else is there to do over these winter evenings!!!

You're chasing a chimera; the odds of finding a chassis with running gear that can deal with a tonne of Meteor without turning into a pretzel that isn't either lorry-based or sufficiently rare like the Phantom to guilt you into not using it are close to nil. Is having a non-Q plate really worth the effort? If you were scratch-building you'd be well on the way by now.

I still own a RR Phantom II and a Phantom III, but the cost of RR parts just kills the project, as well as it has "been done before".

If I could find a suitable light 6 wheel truck (as above) then I would use it. But the Range Rover chassis has a number of advantages and once it is suitably strengthened it will do just fine.

That's basically what I've been saying for ages. Apart from anything, a Merlin/Meteor can weigh up to 750kg, so putting that in a Range Rover designed for a V8 weighing less than a third of that is a recipe for disaster. Even a big Ford Powerstoke diesel only weighs about 440kg. Still, something like an F-650 or International XT/Workstar chassis might be up to the job.

People have been dropping 500kg Cummins diesel's into Land Rovers for years without issue.

Land Rover chassis are very strong, the front axle can be up rated to 2200 Kgs carrying capacity with off the shelf parts.

Wolf steel wheels are rated to 2200kg EACH

If your concerned about strength, order a slightly thicker walled galvanised chassis from richards chassis which is 3mm as opposed to 2mm standard land rover.

It's a truck... it's built to carry heavy loads.

The chassis is plenty strong enough. You can load a classic RR with 5 adults and luggage, then drive it offroad at speed without the chassis breaking! Weakest parts are in the drivetrain (axles, halfshafts etc) because it's all derived from just post war Rover road car mechanicals!

For the cost of uprating the axles to properly handle the power, you might as well just start with some modern stuff that is designed to handle the power! L322 RR has 5.0l supercharged V8, putting out 500bhp, and has chunky front and rear subframes (because unlike the RRS/disco, it has a unitary body construction) that can be easily repurposed and come complete with all the necessary parts. (and there are now plenty of L322 RRs breaking for parts)





You get proper chunky parts, designed for heavy loading, and you get decent handling and ride too (RR suspension is pretty perfect, being designed for a vehicle with a relatively high CofG etc)

Integrating those subframes into a semi-ladder custom chassis is the way to go imo...

It's sad that L322s are now often uneconomical to repair. I'd just take the hit and keep them going. Wonderful cars, especially in any petrol V8 form.

I suspect this one isn't going to get repaired......

The Carmichael weighed over 4 tonnes full of water and I hope my creation will come in at between 2.5 and 3 tonnes.

The use of airbag suspension is a strong possibility but I would like to keep the chassis as original (simple) as possible other than lengthened and a bit of strengthening.

I want to improve the lock on the front axle if possible so may use something else to help with this. It will have power steering and brakes.

The fully dressed Meteor weighs 650kgs. I will be removing quite a few items that get it up to that weight, so hope to end up closer to 550kgs. It will sit behind the front axle and as it is dry sump it will sit low in the chassis. The wheels will be large and the tyres high profile.
This is not planned to be a speed machine. It will probably top 120mph but that's about as much as I want. This is just for fun.

There's a bit more lock in a std RR front swivel that isn't used to limit CV angle (off road, lots of lock, loads of axle torque = busted cvs). Modifying the lock stop bolts should allow you that little bit extra

General Motors did a six wheel motorhome, here's the chassis. It's FWD though, which is probably going to be a showstopper.
