Le Mans M R L Race - Page 2

NHSL · 24 Jun 2013, 21:47 (Ref:3269173)

Sorry, got maths a little out, 240 Kmh is 150 mph, so it's actually 6 cars at 150 or over, and none at 160 or over.

It is our report on the whole 24 hours, but it contains a significant amount of Legend Shots.

I not sure where NHSL gets that stuff from buts it's nonsense.

Jon Minshaw did 189 Roger W 174 and Gareth Burnett 164.The Elites were at 135/131 mph.Most cars now have proper information within the car.

Cars could not lap in 4 40 with those top speeds you give.We had 131 in a Talbot in last years classic.

Don't believe all these lists.

Could your figure be average speed for section 2.

john ruston · 25 Jun 2013, 06:59 (Ref:3269363)

Now had a check on list.

Can't be correct as Lister,R W and rest of bigger engine cars pulled at least 15/20 lengths on Elva on straight so if they did have a check it's placed in a perculiar place.

henk4 · 25 Jun 2013, 07:15 (Ref:3269370)

may be it has been measured on the start-finish straight? (otherwise, yes, for Mulsanne the list makes no sense whatsoever)

FastDB2s · 25 Jun 2013, 07:59 (Ref:3269390)

Its odd that the fastest DB2, Andrew Sharp by some 5 or 6 seconds a lap, has the lowest speed in that chart, the 2nd highest speed achieved for a DB2 was a 2.6ltr engined car.
Very strange as from Andrew & the TV footage he could keep up with Hood's C Type but lost out under braking & I suppose cornering.

gary396 · 25 Jun 2013, 08:00 (Ref:3269391)

If you look at the little graphic at the top of each of the timing sheets it shows the sector points etc and seems to indicate that the speed (TS) was taken along the straight after Tertre Rouge and before the first chicane.

I'm not saying that it was actually taken there or that the data is correct but that is what they've shown.

Mike Bell · 25 Jun 2013, 11:19 (Ref:3269461)

At some circuits in Europe they measure Vmax in the area of a braking point, so a car that has been fast down the straight but brakes early can show a lower speed than one that has been doing the opposite.

If that makes sense.....

FastDB2s · 25 Jun 2013, 11:52 (Ref:3269478)

That sounds about right I guess, thanks Mike

and if they use the braking points that will allow modern cars to slow down enough, you can be sure that vintage cars need to brake at least 50 metres earlier

**John Turner** · 25 Jun 2013, 14:03 (Ref:3269542)

All of which makes these readings and their publication a rather meaningless exercise. J R's figures are more helpful, I feel!

zefarelly · 25 Jun 2013, 14:15 (Ref:3269551)

every drivers different, its the time at the end of the lap that counts

simon drabble · 25 Jun 2013, 14:23 (Ref:3269554)

Joe is correct - fastest speed at a given point on the circuit does not always equate to fastest lap time.

Generally yes, but in the case of Le Mans it makes a hell of a difference if a car does 180 mph on the Mulsanne straight or 165, as John was telling about the catching up poor Gareth had to do with his Elva.

FastDB2s · 25 Jun 2013, 14:56 (Ref:3269569)

More interesting are the sector times, it would help if we knew where the sector's start & finish

zefarelly · 25 Jun 2013, 15:06 (Ref:3269573)

Agreed . . . . first time I raced and we got those sectors was Goodwood in 2011 they make for trainspotterly interesting reading, and I think I learnt something from them, we had them at Spa too recently

sure, but I don't know whether they were recorded. As I was outside during the track action I could not see the screens in the press center which normally show the sector times. The were not made available after the practice and the race.

Then open the LM L +, then race +, then 'best sector times'

FastDB2s · 25 Jun 2013, 15:15 (Ref:3269580)

Scroll down the page & the sector map is on there, S1 is from the start ? to middle of Tetre Rouge, S2 is the Mulsanne straight to middle of Mulsanne corner, S3 is back to the start / finish ?

thanks, and to make it more clear go to practice and find the sector times there, the race was done under moist to wet conditions, while practice was dry. Here you find that Burnett is losing 5 seconds in sector two and just a couple in the other 2 sectors together. The speed of Buncombe through sector three is astonishing.

Alex's Mychron rev counter/lap timer gives sector times and one quiet evening I went all anal and prepped a spreadsheet. Found his theoretical fastest lap time would have put him top of the pile if he'd strung it together. It gave us great confidence that the kart was at least in the ball park, you can learn a lot from boring data.

john ruston · 25 Jun 2013, 22:38 (Ref:3269763)

John Minshaw 179 not 189!
Still very,very fast.

The part into Indanapolis is very quick

I was onlt 0.1 off my theroretical best . . .which suggests the car and driver are average at best!

All those front running cars are quick, competitive cars, well prepped and they get plenty of practice.

midgetman · 26 Jun 2013, 07:29 (Ref:3269868)

179 or 189 that's still very, very quick on those narrow tyres and ancient suspension!

Yes Zef, definitely it's the practice, practice, practice that helps. That's where money counts in any sport, the ability to go out and do it regularly to keep your skills sharp.

Narrow tyres = less drag. No downforce = less drag. Double wishbones at front and De-Dion at back on a lot of that era cars, and if properly engineered and set up should be fine. Then we come to the brakes...........
