I suppose most of you would have seen this video of the 1980 Tricentrol Group 1 Championship part 1, with a good bit of footage of Brian Jones interviewing Stirling Moss on the grid at Mallory Park.
It's just as well that we have time on our hands to waste as it's a long video

https://www.youtube.com/watch?v=cpZThuhr8tA Pity I can't find a part 2!

There is/was a 2nd part somewhere.or rather 2 parts of the first half of that year. Posted by Inqisitor or something?

There's also 2 parts for the '81 season which some complete joker uploaded!

Yes I did note who put it on, it could do with a bit of colour/exposure work

I could do it for you

Anyone keeping an eye on the America's Cup build up events?

Remarkable boats. I heard somewhere that they can sail at something like 50 knots against a 15 to 18 knot wind. Or something like that.

Just imagine if F1 could do something similar with their Aero technology and find extra speed whilst making it impossible for anyone to pass.

Not half! Love watching Sir Ben at work; they were a shambles just a few weeks ago, re-rigged the boat, re-jigged the crew, and now they have 4 straight wins, amazing. An then the oppos have the cheek to accuse us of sandbagging.

Well other than the part 1 linked I could only find BTCC 1981 parts 1&2 posted by "Chunterer" (presumably of this parish)
All good viewing of the time.

Edit: Just noticed the posts following mention this.

I would guess unlikely given the amount of winter testing that seems to be undertaken. But what if, over time, some under panels are mislaid? Is there potential of greater risk or reduced risk for some vehicles absent the undertray components?

As you say , manufacturers spend a lot of time & money nowadays testing so that airflow & water/ snow ingress should not affect the running of their cars .
Have seen lots of cars with " Boy Racer " type air filters on , and most of the time , although they think they sound "better " , they will lose a lot of power because the air flow is not as good as the original design .

The same with under tray guards . If they are left off , there is a good chance that water / snow will be directed up into the engine compartment .

May be they already do? Hence the DRS system meaning Drag Reduction System. Good for overtaking, reducing the drag and make full profit of the draft. You can find a lot of info re draft in Nascar events, the fast cow boys having a huge know how about this.

I get the impression that Nascar (in particular and due to the nature of the oval races) have a feel for the way that bumper to bumper racing is somewhat beneficial in Aero terms to both cars (or, in deed, all cars in a line.)

However what if, somehow, it would be possible to create an Aero shape that acted in conjunction with local air movements to provide forward momentum? (Whilst at the same time generating a horribly messy air wake to prevent others benefiting as well)?

OK, Physics probably makes that impossible and ground level effects of air movement are not the same as wind and sails.

By comparison DRS is a very blunt tool. Just a reverse air brake really.

Gerard C · 18 Jan 2021, 15:56 (Ref:4029861)

Air movement to wind and sails are way different and much more complicated, because you have to take in count the reaction of the forces applied on the keel. Not forgetting that the sails work like a wing, intrados and extrados, and that the jib influences the main sail…*That's why some boats can go faster than the wind.

Haha. It did try and play about with it but the footage was uploaded from a dvd i received which in itself had already been transferred from a VHS with apparent tracking issues!

This stuff is total gold dust. Still looking for the 2nd half of '81 and the whole '82 season.

I know it's out there!!

As an aside, when you watch the velodrome pursuit races, they use 20% less energy at the back of the line than at the front, so the giys have quite a good rest.

I once joined a "peloton" of my local club riders around Castle Combe Circuit, I could keep up with the group in the slipstream but when it became my turn to take the lead I couldn't ride fast enough to get to the front

When I was racing karts back in the **** [ was it that long ago?] .
Did mostly the motor racing circuits with a gearbox class . Slipstreaming was quite important , even with our very low profile .
Depending on various factors , we could pick up a tow from 10 to 20 yds behind . You would feel it suddenly getting faster , close up on the one in front , back off the throttle until the right amount before the next corner , then full power would slingshot you past .

Then someone had the bright idea of closing up until you touched their rear bumper , [ only with someone you could trust ], then full power again and the both of you could go far quicker together than possible just by yourself .
This had some quite amazing effects until the RAC/MSA/ MSUK decided that pushing at 120 to 150 MPH was not considered safe so they put a ban on it .
But it was fun for a time .
