You then battle in the LMP2 category.

Weight
Weight (Kg)

-- Bulletin --	--- Track ---	FERRARI	ASTON MARTIN	PORSCHE	CORVETTE
1/3/2023	Sebring	1264	1262	1300	1289
6/4/2023	Portimao	1263	1245	1269	1265
19/4/2023	Spa	1263	1245	1269	1265
26/5/2023	Le Mans	1263	1245	1269	1265
		488 GTE EVO	VANTAGE AMR	911 RSR - 19	C8.R

Corrections after Sebring and then nothing since.

On top of that there are adjustments for specific entries depending on previous results:
Succes Ballast (kg)

-- Bulletin --	--- Track ---	#33	#77	#57	#83	#21	#85
1/3/2023	Sebring	0	0	0	0	0	0
6/4/2023	Portimao	30	20	10	0	0	0
19/4/2023	Spa	45	20	5	10	5	5
26/5/2023	Le Mans	0	0	0	0	0	0
		CORVETTE RACING	DEMPSEY-PROTON RACING	KESSEL RACING	RICHARD MILLE AF CORSE	AF CORSE	AF CORSE

This is limited to a maximum of 45kg

Corvette #33 has hit the max.

This part is irrelevant for Le Mans as all success ballast is removed.

Stints
MAXIMUM ONBOARD FUEL VOLUME (liter)

-- Bulletin --	--- Track ---	FERRARI	ASTON MARTIN	PORSCHE	CORVETTE
1/3/2023	Sebring	89	88	101	95
6/4/2023	Portimao	89	88	101	95
19/4/2023	Spa	89	89	101	95
26/5/2023	Le Mans	88	97	102	96
		488 GTE EVO	VANTAGE AMR	911 RSR - 19	C8.R

Aston been given a decent chunk more fuel for Le Mans.

The proxy for engine power

Pboost ratio* (RPM) / MAXIMUM RESTRICTOR DIAMETER (mm)

-- Bulletin --	--- Track ---	FERRARI	ASTON MARTIN	PORSCHE	CORVETTE
1/3/2023	Sebring	1.78 (5,500)	1.42 (6,000)	30.6 mm	41.3 mm
6/4/2023	Portimao	1.78 (5,500)	1.42 (6,000)	30.6 mm	41.3 mm
19/4/2023	Spa	1.78 (5,500)	1.44 (6,000)	30.6 mm	41.3 mm
26/5/2023	Le Mans	1.75 (5,500)	1.49 (6,000)	30.7 mm	41.3 mm
		488 GTE EVO	VANTAGE AMR	911 RSR - 19	C8.R

* Boost is set at different RPMs, this just shows the boost at the 5th highest RPM listed. It gives an idea of the overall change as it tends to move the same at all RPM, but it might not.

There is also Minimum Rear Wing Angle with respect to floor adjustments that can be made.

Thanks for the clarifications and congrats for another fantastic job. Re the fuel volume (based on the mini allowed to the 488's) I think the RSR's can make one more lap than all others but absolutely not sure about the Astons and 'Vettes. At LM there are many places where you're WOT for a long while. No doubt we'll see another fantastic battle in this category.

From s365:

"The FIA and ACO, meanwhile, have confirmed that no additional BoP adjustments will be made to the Hypercar class between Sunday’s test day and race week itself, with the current figures locked in for the duration of the event"

Great to hear, just like they said no BOP changes until after Le Mans, and just like they said only platform changes. Glad they have stabilized things ...

[Adam43]

Which is now the problem. They said it before.

Arguably, it would actually be quite a reasonable thing to do. Data at the actual circuit!

But I’m fine with the no change.

[Sodemo]

What the ACO said was the truth until it wasn’t.

[LC2guy]

As a neutral looking for a titanic battle, i was looking forward to Toyota vs Ferrari. Now looking forward to Porsche vs Cadillac.

I think that is their motto

Not only about ACO…

The MaFIA as well?

[Gerard C]

As well and may be more!

[crooky]

Get the important question in first. When's the last point that BOP can be adjusted for the Hypercars?

Next question, please…

The warm up lap.

Thank goodness. I thought all the similar times in testing were some sort of sandbagging for BOP purposes.

It is because of BoP! That makes the cars close!

They aren’t driving around looking at the timing screen saying, “I know I’ll set the same time as the others.”

And sandbagging is often attributed to test times. Even before BoP. Whereas the teams are actually just going through their programs. And not trying for times.

Be prepared to be surprised that times get quicker through the week!

Fully expect qualifying times to be down to 3:24 and under and race laps in the 3:28 region. ****ed at myself that I missed the deadline for the prediction thread (Timezone woes)

[Adam43]

I’m hoping for a 23s.

[veeten]

with Ferrari, Toyota, Porsche, and Cadillac with 2 cars apiece in the Hyperpole tomorrow, it looks like he powers that be have accomplished what they have set out to present. Even the entire Hypercar field was only a few tenths apart, when you consider the number of entrants involved.

Yeah, it looks good so far, but I don't think we'll know the full story until hour 2 or 3 of the race.

I think Toyota will hit about 1:23:750. Will Ferrari be faster? Possibly. The car looks a touch faster over a single lap than the Toyotas, but it looks absolutely on the ragged edge while doing it.


Hyperpole is gonna be quite entertaining. Looks like the Porsches sold some bags of sand.

And seems the buyer was Peugeot I was really hoping for that shitbox to show some pace but no... it's a doomed concept imo.

[JHamilton]

Close but pants is my final analysis.
