The fuel capacity is free for the 6 hour.

Possible explanation on fuel capacity?

Free? But isn't there a period size fuel cell restricted to Fia K?

Seems pretty dangerous to me to haul too much fuel in lightweight racing cars . . .

GT40: Minshaw won the 2010 edition of the Spa 6 hrs in the E-type. The dark blue Clark E-type is always running smooth and top 10ish.

Campagnes Corvette looks like a candidate for 2013.

Sports racers were always free on fuel capacity (although there is a natural cap due to size, my Merlyn ran with 2 x 40 litre fuel tanks) but I was under the impression that GT and saloons had to run to their homologated tanks. Shame if that is not the case

Think fuel tank capacity is covered by App J appropriate to the period, and related to engine capacity. Haven't got 60s docs to hand but in 1971 it was max 120 litres for over 2500cc.

Unless separately homologated... jaguar Mk2 is homologated at 160 litres

Make sure you adjust the tyre pressures Simon!

Think the 'B' has homologated bigger than App J 100 litre as well?

Tank sizes- 1965 App J is here (page 236) and 1966 is here (page 14)

Think that is what governs capacity we use, unless homologated differently.

My reading is that the capacity "may in no case exceed" the limits. Is there a reference elsewhere to homologated capacity? I can't see one.

I'm reliably informed that E-Types have a 140l homologated tanks but used even larger tanks at Le Mans.

What is the best strategy for long distance races?

140 Litres @ 0.737kg per litre = 103.10 Kg

Is there any advantage carrying the weight? the alternative being more frequent refuelling.

At Spa in particular, it can take so long to fuel that if you can eliminate one fuel stop, it's well worth it. A long drive in from the modern pit round to the station then a possible wait for the pumps etc....Also, the longer you can go before fuelling the better, as you get out of "sync" with most other cars reducing the likelihood of queuing for fuel.

The fueling 'sight & sound' is spectacular. Queues may vary in length, but imagine the time fueling 120 litres. It eats time and it is easily a 15 minute killer.

Setting up a 1100 kgs racing car with or without 120 kgs must be quite a puzzle.

That was the good thing about the B,one stop for the whole six hours. Before I fitted the big tank,it would take three stops. No brainer.

Well, I'm getting excited about 2014 6hrs. This year have 'only' a shared 90 minute race in GD, but if all goes to plan next year Delta and I will be entering my little Gilbern GT in the main event. Currently resting, it will be Gilbert Gilbern's next big adventure......
