I'm running in the 24hr endurance de la Sarthe I race with a CLK GTR race car, fully modded to 1031bhp with hard tyres on the front and superhard on the rear.
Problem, on A-spec I'm having to pit every 5 laps for both tyres and fuel, on B-spec mode the car spends more time in the gravel than on the track.
I'm only gaining a lead of around 55sec by the time the nest pit stop is due, a lead which is all but wiped out by the time the car is re-fuelled, despite running on average 3.14 lap times.
Any suggestions on how i can extend the interval between pit stops?????

use the minolta on a-spec or b-spec

i can't help but feel that you aren't really answering the guys question... crikey if you just got out and walked you wouldn't use any fuel or tires at all. i think he is more asking how to improve his fuel economy and tire useage on his merc.

for that i would try first raising the ride height to max at the back, and about 10-15mm below that in the front. Then loosen up your suspension (to around 8 or 10). this should help with your tire wear - as well as probably making your car quicker in general.

Fuel economy is modeled on engine power and duration of full throttle application (revs aren't related) - the more powerful the engine - the more fuel it uses. You are probably going to be stuck on the CLK because with less engine power you may not win (or at least it will be more of a struggle).
 
Better yet, use the 04 Pescarolo with R3 / R2 tires, slap on a Stage 4 turbo, and you should be able to pit every 8 laps, not to mention that you'll be kicking the competition's butt with the tire advantage and the turbo.
 
yet again - the question is not how to win the race (thank goodness - because 1327 seperate threads on the same subject probably aren't required) - but how to improve tire life and fuel consumption. For that - try my previous post.

If you want a list of cars that will win, then from the top, i would go for a 787B, C9, R8, R92 88C-V, XJR-9, 905... etc.
 
u know tire life sucs no matter what u do u cant improve tire life u got to be joking and same with gas it depends on the car with the minolta i didn't pit for almost 10 laps
 
When I did my Le Mans car test on Sarthe II (no chicanes on the straight), the Mercedes did fairly well:

On Sarthe II the race was never in question. The CLK-GTR (which is actually a CLK-LM, of course) cruised away and after four hours had a commanding lead. Your post gave me the motivation to see what would happen on Sarthe I. As I type this I'm running a brand new car, starting the race with 0.0 miles on it, and it looks like its a different story when the chicanes are added.

I'm using the "3" speed setting because B-Spec Bob can't keep it on the track at "4". "Overtake" is on, of course. The car has Stage 4 power, R2/R1 tires, stock suspension settings, 0/0 ASM, TCS at 5, and brakes at the stock 3/3 setting.

I stayed with the "default" AI field that comes up when you initially enter the race: R92CP, R89C, Audi R8, Playstation Pesky, and Corvette C5-R. (I didn't exit and re-enter to get the two bad boys of the event, the Sauber Mercedes and Minolta Toyota.) The car goes 7 laps between pit stops, with fuel triggering the stop because it only has about 7 liters of gas left when it pits.

Bob is driving error-free, but after 37 laps (2:10 into the 24 hours), he is in second, two seconds behind the R92CP. The race is definitely in doubt. I may run the whole race like this some time just to see what happens. This could get really good.

From what I'm seeing here, I'd say that you may not be able to win this race with this car, but that will depend on the field of AI competitors. In A-Spec mode you will burn your tires up much faster, and I can see how you're only getting five laps on a set. I don't think there is anything you can do about that. If the cars you're racing are decent, you'll have a formidable task ahead of you.
 
I used this car fully modded in the other race.
If you do not intend to stop and start again, you cannot change settings and would have to adjust your driving style.
If you stop, I would take the stage 4 turbo off. raise the height and slightly soften the bound and maybe springs. Set brakes to way soft and try to carry more speed through the chicanes.

If you are stuck in the race you can win on those time I think.
If you don't start again, put superhards on tthe front too, this should get you seven laps, if you aren't too heavy on the brakes.

No matter what setup, this car CAN runout of gas at the end of the seventh lap in the racewithout chicanes, thats why turning the stage 4 turbo off (you dion't actually need it), can win you the race in this car! 👍

Good luck!

Joking? pretty funny i guess - but do this little 'joke' for me. put the car with a very stiff setup and see how long it takes for the tires to go red - then go change to a soft setup, and again check how long it takes for the red. If it takes the same time - then my theory was a joke, if not, then you are a joke...

as i said, fuel consumption is related to power and throttle application (not revs). hence when a car has less power (ie no stg 4 turbo) it will use less fuel.

Really? I just checked it, and at the "1" (slow down) speed setting, with stock power, R2/R1 tires, and Autoset at 15, Bob was forced to pit at the end of lap eight with bright red-orange rear tires and just 3 liters of gas left.

Please tell us how you managed to go 10 laps on Sarthe I with the 88C-V.
 
probably without the stage 4 turbo i am guessing. but i wouldn't be all that surprised if the finer details were a little 'smudged'.
 
woops, missed that bit - must be my second theory (re the smudged details). its amazing how some people's recollection of facts is almost always biassed towards supporting their own theories...
 
Thanks for the suggestions. I'll try sorting the suspension settings and drop stage 4. If that doesn't work looks like it'll be the Pesky.

I used the black nissan R390 with over 30,00 km on the clock and only stage 3 turbo. If you dont take the first race, i.e. exit - (doesn't hurt your win ratio) and start again you get rid of the audi R8 and pesky as competition.
I won with 3 minutes lead due to distractions at several points during the race including running out of gas, you could win by three laps in this car without stage four and without the audi and pesky to bother you.
My times to win were 3:23.xxx at best so dropping the competition level and racing as you are in the CLK will also get you that win. I got 87 A-Spec points, I dont b-spec.
 
My b-spec rating is pretty high and I still fly off the end of the long straight. Is it possible to tune the car to brake earlier?

[I've tried adjusting the brake bias, tires, ride height, downforce with no luck]

Thanks for any replies!

I used the '04 Pescarolo, stage 4 turbo and had no problems with the corner. Brake bias was 5/5, R2/R1 tires.
 
I just did a test to confirm less downforce prolongs tire life.

Test is easy, Take a F1 car to the Formula GT, get on the Motegy High Speed Track. Let B-spec Bob Run the race with Full downforce, he will pit lap 13, drop your downforce 50% front and back, you will pit lap 15 (roughly a 2 lap gap for 50% of your DF. I dont sugest to go with a 50% reduction, But light reductions will add life to the tires to help you push the distance between pits.

For that Race I sugest a Minolta or R8 with R4's up front and R2's in the rear.
 
This was the sarthe without chicanes, right? I used the 787B for that. Best overall tirelife/fuel economy. Of course I did´nt add any power, but on Sarthe that is´nt such great deal (well, you have to have enough to be competitive), just take away some downforce. On Sarthe, half will be fine. And adjust suspension too.

The ASM [oversteer/understeer] setting of zero was critical in getting my Audi R8 stopped at the end of the long straight on LeMans. [using B-spec]

That car is a dog being underpowered and overweight. Go with the Minolta Toyota, Audi R8, Playstation Pesky or the Bentley Speed 8 to easily win in B-spec. That CLK Mercedes is overweight and eats tires for lunch. I've gotten seven laps easy from tires using any of the above cars on Sarthe. Stay away from the Jag LMP, Sauber Merc, Gillet and any Ford GT when it comes to tire wear.
 
I'm currently in the middle of the 1st 24hr Sarthe race with my '88 Jaguar XJR-9. I am running very little downforce and I'm using Ducks suspension and other suggestions but a very high auto gear ratio but with a stock final drive ratio.
I started it a 2am this morning on B-Spec and when I woke up at 7am I was in first place with a 1 lap lead on 1st & 2nd place and anywhere from a 4-7 lap lead on everyone one else.
