Abrams engine, drive and suspension on a new, narrowed lightweight carbon-fibre hull.
Some sort of rubberized track system, just enough 'tooth' for traction but smooth enough
for high-speeds.

Mrs Kitnut's Dad was in the REME. During that time he was on the 'Recovery Team' and on one call he had to attend a crash. Apparently (and this was straight from the horse's mouth), he had to go recover a Scorpion tank which had shed a track. Only this was on an 'M' road in the UK. It had been doing over 95 mph when the track decided it had enough and the end result was it ran over a few civilian vehicles.  After that a governor was added to the drive train to restrict the top speed considerably.

I'm note sure about 95mph but a few years ago we (the RAF Regt) held the tracked land speed record in a Scorpion (or perhaps a Spartan) and I think it was something like 75mph. This was achieved by closing off a section of the A1 dual carriageway close to RAF Catterick and pulling out all the stops. Interesting thing is that the following week the same vehicle had a catastrophic failure of one of its front drive sprockets causing a track to shed. Fortunately it wasn't going that fast but still ended up in some unsuspecting persons front garden. Just as well it didn't happen when doing its speed run.

Do you have Crismon's book on US Military Tracked Vehicles? In the APC section with the M113, it shows the vehicle that set the record on a gravel track at Aberdeen back in the '60s or '70s, I think.

What's particularly impressive is that it achieved those speeds over a gravel track. Makes you wonder what it could do on pavement.

Speaking of 'hot rodding' and military vehicles (yeah I know no tracks),
Wally Parks with his Philippines ride, a 'Jeep' (which may be a Bantam),
that he hot-rodded with a massaged 136 cu in (2.2 L) Ford V8-60 flathead.

For those not familiar with Wally Parks he was a co-founder of Hot Rod magazine and founder of the
NHRA.

That reminds me of Bill Mauldin's short story, "The Affair of the Wayward Jeep" (q.v.) where a hot-rodder gets assigned as a general's driver and massages the general's jeep in true hotrodding manner.

Indeed.  The lower hull comes from the CR1 I used for LRB's Cambodian King Tiger, the upper hull was from a long forgotten CRARRV conversion and some Chieftain spares make up the third kit.

Post by: Claymore on July 02, 2017, 05:06:24 PM
I'm thinking that there could be a whole range of possibilities from, the down and very dirty, cross country to high-speed sprints. All would probably need to be time trials to prevent massed carnage - a bit like modern day rally-cross and drag-racing. The types of tracks used (padded or bare steel) would also be a limiting factor for the type of race and the surface used - probably would not want plain steel tracks on a sprint run on a hard/road surface. The possibilities are almost endless with different classifications for weight, type of race, etc and various  limitations such as engine type, power output, crew carried, etc. Just look at the world of car racing to see the variety...

Blimey, this could be a whole new world of tanking!  ;)

Claymore, do you remember the BBC series back in the 60's-70's that had all types of all-terrain vehicles racing down a hillside in pairs, across a bog in the bottom then up the other side. I remember a Scorpion doing it one time ---  you project reminds me of that.

A very long time ago.  I had one of the Matchbox Stalwarts that was printed up in BP colours for some kind of race.  One of my favorite wheeled vehicles.

Oh wow, I had that Matchbox BP Stalwart as kid and just about wore it out playing with it!

Anyway, I love the racing Challenger! Not only do I think it'll look great in full race livery but it could work as a recce type vehicle with a small turret or weapons station.

Post by: Old Wombat on July 03, 2017, 10:32:09 PM
With the loss of mass from cutting away a road-wheel in length & getting rid of the turret I reckon she'll be quite quick & nimble, as both a racer & a recce vehicle. 8)
Title: Re: Tracked Land Speed Record Contender
Post by: Claymore on July 04, 2017, 06:33:56 AM
Thanks.

Hopefully my intended colour scheme will do it justice.

Indeed, with a set of road wheels, turret and large portion of hull removed she would be quite a bit lighter but still has the big 1200hp Rolls Royce/Perkins engine (race tuned of course) to push her along. I'm not sure how much weight would be lost but perhaps down to 30 tonnes? What do you think?

That'd be pretty close, so you're looking at about 40hp/tonne or approx 29kW/tonne (vs 14.4 kW / tonne for the full vehicle).

Well, as they no longer run the Paris-Dakar from Paris to Dakar due to safety concerns, maybe in this 'Verse they said "Damn the locals!" (in French, obviously) & ran the old course bullets, bombs & all but with appropriate safety precautions!

Perkins also do an uprated version of the CV12 Condor engine which pushes out 1,500hp (1,120kW). I might use this as the race tuned engine and so we could be looking at 50hp/tonne or approx 37kW/tonne. Now I reckon that wouldn't be too lethargic off the mark!  :o

Tracked Land Speed Record:

In 2010, the Russian Army introduced the ‘Tank Biathlon’ series of Military Games in which, similar to the winter sport of biathlon, tank crews compete to demonstrate their rough terrain driving skills combined with the ability to provide accurate and rapid fire while performing manoeuvres.  These games proved to be a great success and increasingly took on an international flavour as more countries sent their crews and MBTs to participate.

(http://i.imgur.com/xC0dclk.jpg)

Of course ownership of armoured vehicles is not the sole domain of the world’s militaries and it didn’t take long for the private sector to show an interest in what the Russians were doing.  Having said that, for very good reasons there are laws in most civilised counties preventing civilians from owning large calibre artillery pieces and/or the ammunition for said artillery pieces and, consequently, any civilian take on the tank biathlons would have to have a somewhat different flavour.

So it was that the sport of tank racing was born.  The early days, saw a series of meets where gentlemen with more money than was probably good for them came together with their ex-military service vehicle to compete in a variety of cross-country time trials where they could show off their prowess in command of their respective armoured toys.

(http://i.imgur.com/r1Go5Vv.jpg) (http://i.imgur.com/DIJ7R1f.jpg) (http://i.imgur.com/W0maVzy.png)

It didn’t take long for the media to take an interest and for sponsors to realise that there was money to be made from this new and novel sport.  As the public interest and financial rewards of the new sport spiralled, the imperative to quickly tie down an effective set of rules and regulations quickly resulted in two very distinct avenues of development:  Tank Rallying and Tank Drag Racing.  In order to maintain an element of competition, a number of sub categories were introduced to both racing styles specifying, amongst a myriad of technical minutia, all up weight and engine type.

With the desire to increase the performance of their armoured steeds, it wasn’t long before teams starting making alterations to their vehicles in order to improve performance/handling/speed whilst staying inside the constraints of the sport’s regulations.  Generally, the first thing to go was the redundant main gun which, if not welded or clamped in place, only served to put unwanted sheer-pressures onto the turret.  Not entirely surprisingly, the entire turret was next to go as teams endeavoured to reduce the weight category of their vehicle whilst keeping the original power train.

(http://i.imgur.com/tnar0Yo.jpg)

These and a number of more subtle developments led to some very sleek and surprisingly fast armoured vehicles.  However, it was the appearance of Team Claymore’s cut down Challenger 1 in 2017 that entirely revolutionised the sport.  What they had done was to take a standard Challenger 1, remove its turret and then remove the portion of the hull that the turret sat on.  This process also reduced its number of road wheels per side from 6 to 4.  The end result was a reduction in the vehicle’s original 62 tonne to 30 tonnes.  At the same time, the vehicle’s 26 litre, 1,200hp, Perkins CV-12 Condor engine was upgraded and race tuned to output 1,500hp.  In other words, the vehicle’s power to weight ratio was boosted from 19.4 hp/tonne to 50 hp/tonne.

When entered into the 30-tonne class of both the Rally and Drag Races, Team Claymore’s vehicles (01 and 02) were the run-away winners and set a new tank land-speed record of 80.2 mph (128.3 Km/h).

The model depicts Team Claymore’s vehicle ‘02’ which won the European Tank Rally Championship in record time and then which went on to set a new World Tracked Speed Record in its class.  It is made from parts from two different Tamiya Challenger 1 models, some pieces from a Takom Chieftain Mk 11, plastic card and a selection of home grown decals.
