Is that the garage by the level crossing, just by the end of the platforms ?

 

 I haven’t walked along there for a couple of years, but it always had something interesting for sale !!

 

cheers,

Phil.

It is, nothing has prices but I understand they are for sale at the right price. Both look absolutely mint

Given low mileage and condition, my guess would be probably garaged over winter and sorn’d. Brought out for MOT so it can be taxed now the weather is getting better (ish)

The building next door is used for storage (see my other post in old car thread)  so sounds feasable .there was a lotus and a escort cosworth at the back amongst the caravans and trailers

It's SORNed according to DVLA.

And passed its MoT yesterday but not after repair of a front ball joint which apparently was so bad it was in danger of letting go!

Not spoilers - they are 'pram handles', used for pushing it (well it is a Ford).

I know your joking, but for the record those “pram handles” actually did a useful job at speeds over 80 mph and exactly why there were two, we tried one (I have worked with the aerodynamicist who was in the team, Noel Watts) with a single large wing just like the later Cosworth but it was deemed “too much” for the time and marketing preferred two as quite a few cars had just one already.

I found the limit at which a Sierra Cosworth willl start to let go.

 

Was slightly lower than my bike at the times cornering limit.

 

I had production racing series tyres on, was first bike radials, gripped like nothing else and the tread stayed on the carcase. Also 5x longer life than a not as grippy tyre.

 

Production series racing on bikes HAD to filter to road usage.

 

And the jelly mould could not keep up.

 

Bike radials were game changers, 10% higher price saved a fortune, 5x longer life

4x on front 5x on rear

At what speed and do you mean cornering?

 

We tested the Cossy at over 170 mph at Lommel in Belgium (in England at Millbrook’s high speed bowl wouldn’t allow us over 145 mph due to suspension compression) and it was fine, if a a little crazy, especially with a video recorder on my lap :lol:

Um there was a one at the front and a few seconds later I red lined in 5th, my foot was near the road and I was right over. Also many years ago, like 1980s.

 

The Cosworth was basically unwieldy and not that quick up to a ton. No match for a sports bike.

 

Oh and I had passed it in traffic then after the traffic he tried to play catch up, so I thought no.

Gammers. I've never been sure they were for sale or show. They've had some cracking motors in there over the years. 

 

C6T.

Oh and when I had that bike I got stopped on the way back from Bristol exhibition, not done but told to slow down!

 

Not had a bike  for 30 years as I know what would happen (again).

It was quite fast for a saloon back in 1984/5........but as we always used to say about bikes, just fast cars with all the safe bits taken off ;)

 

A lot of our engineers rode bikes but would never ride them as fast as they drove the Cossies on the Essex country Lanes......

No, two spoilers is the thin edge of the wedge.

Its like razors, they used to have the one blade. Then some bright spark thought two would sell better, one to cut the bristle and an extra   one to cut a bit more off before the bristle was able to retreat back into its hole..

 

Then it all went mental with increasingly more and more blades  until now where we have  blade 3 which has hostage negotiation skills and is able to talk the bristle out  while blades 4 and 5  overpower it and take it away for questioning while blade 6 read it its rights  and blade 7 armed with a sniper rifle is on overwatch  in case things go wrong

 

If your spoiler development had similarly reached its logical conclusion you'd have re-invented the rear louvre.

It did indeed, I suppose it’s one of those things has it been introduced as planned with 3 spoilers then wheeler dealers cut one out to make a twin blade version then I’d be saying that looked wrong too

No, you didn’t get it.....one wing (it’s not a spoiler) worked perfectly well (hence the later whale tail on the cossy) it was marketing/styling who insisted on having two layered wings.

The original ordinary Sierra had a problem with aerodynamics. They would become unstable at 70mph due to their shape. They had to put little extra bits of trim on the upper rear quarter panel to break up the air flow and stop the lifting effect. It could well be that the Cossie really did need the two wings. Maybe it’s more about breaking down the upforce rather than creating a downforce.
