WEC Race 2023 Round 5 - 6 Hours of Monza [RACE THREAD]

Simmi · 8 Jul 2023, 09:56 (Ref:4167162)

No race thread yet but given we're into the new era I think we deserve one!

Basic live timing here: https://live.fiawec.com/en/

Entry list: https://press.fiawec.com/assets/file...c177dae8d8.pdf

Repeat of FP3 here: https://www.youtube.com/live/2GlyXsotpfQ?feature=share

All set up quite nicely after FP3. Peugeot fastest. Toyota looking a little bit lost and the Porsches also looking a bit fragile.

A bit of fever on track

**Adam43** · 8 Jul 2023, 11:44 (Ref:4167170)

Simmi - thanks for starting the thread. I've stuck it at the top.

Each practice session has a different story looking at the fast times.
Obviously some sandbagging going on

Glickenhaus has a top speed advantage, but it could just be a good tow. I haven’t looked at all the data yet, but they’ve had at least two laps with a top speed faster than the others.

**joeb** · 8 Jul 2023, 11:47 (Ref:4167172)

Peugeot tops FP3! Ahead of a Ferrari and they were the only 2 cars below a 1:36. I expect most of the class to be in the 1:35's come qualifying in an hours time.

Green for GT qualifying and the entire field seems to be headed out in a pack.

A bit daft. But you need to maximise the lappery.

I'm watching in a bit. Currently too busy trying to going...

**Adam43** · 8 Jul 2023, 12:52 (Ref:4167179)

In practice it is clear that the Glickenhaus has a good Top Speed advantage - it wasn't jsut one or two laps.

LM P2 was tight, with WRT coming out way ahead of everyone else.

Hypercar is just about to start

**joeb** · 8 Jul 2023, 13:47 (Ref:4167187)

Lots of garage pictures of Toyota while cars are still circulating....

kaivo · 8 Jul 2023, 13:48 (Ref:4167188)

I just wanted a chance to see all the cars for a turn or two, I understand you have to focus on the cars at the front in qualifying, but when they are parked please show the other cars!

Gerard C · 8 Jul 2023, 15:03 (Ref:4167200)

Good and useful job again Adam, thanks. I cant remember if the rev limit is fixed by the regulation tho. From the on-board images I see Toyota hitting the 8K mark, Peugeot weel above in the region of 8,5k and Ferrari around 7,2k. Or may be what is shown on TV is not accurate? Would not be surprising…

tomcug · 8 Jul 2023, 15:13 (Ref:4167201)

For LMDh tech regs say this:

Quote:

ICE speed is limited to 10,000 rpm

For LMH there's no limit in the regs. And obviously, the above quote doesn't mean an engine in every LMDh car needs to rev up to 10k RPM

Gerard C · 8 Jul 2023, 15:22 (Ref:4167204)

Merci beaucoup for the clarification tomcug. As to the max speed achieved, it seems the differences are now not the same as shown during practice. For instance #8: 315,8 and #4 Vanwall 305 kph.

tomcug · 8 Jul 2023, 15:29 (Ref:4167205)

Also another info, IMSA is publishing Nmax in their BOP so we can see the rev limit:
https://www.imsa.com/wp-content/uplo...P-06292023.pdf
The ACO doesn't however, for whatever the reason.

Gerard C · 8 Jul 2023, 15:34 (Ref:4167208)

Thanks again.

Gerard C · 8 Jul 2023, 15:56 (Ref:4167210)

LMP2 top speeds: first Vector Sport #10 with 296 kph, last… Inter Europol #34 doing 286 kph. May they've not received the confiscated parts at LM from Geneva?

All the engines have different maximum revs. Power is then set through each car’s rev range and pretty similar for all. Apart from small BoP differences. So the max power is set at a specific rev, but I don’t know if the ref limit is. However, I suspect that in top gear they aren't near it - the power drops off and, if I remember correctly, the gear ratios are set for the season. Although abviously at a place like Monza they will be the closest to the limit.

Edit. Ah, I see tomcug gave them in IMSA. I guess the Porsche and the Cadillac are the same, or very similar, in WEC?

Bit of a shame, it would be interesting, but it doesn’t really make much difference.

FWIW. Here are all the power curves (as of May 9th)

Everything in the engine mangement, Rpm's ignition injection intake pressure is fixed and monitored step by step. Always impressed by your MG B engine, Adam…

Gerard C · 8 Jul 2023, 15:49 (Ref:4167209)

Good view on the suspension travel and how it works here https://www.youtube.com/watch?v=JtT8PEt5EWE from 24'50. Yeah, french comments but any language would fit in this matter.

Gerard C · 8 Jul 2023, 16:11 (Ref:4167213)

I find strange things between the live timing and when the timing results are diplayed. May be Monza time is not the same as Paris'? Not talking about the live streaming which I find could be, may be and when possible, improved…Grande casino!

**Adam43** · 8 Jul 2023, 19:17 (Ref:4167243)

Anyway. Hyper close again! Impressive.

Will Toyota regain the top now we don’t have tyre warmers again?

yes, very much impressive. As to the revs you can add some influence ont the fuel consumption. C'est toujours une affaire de compromis.

v8supes · 9 Jul 2023, 10:34 (Ref:4167339)

Very exciting watching a huge field of prototypes heading down towards the first corner. Traffic is going to be crazy in the first hour.

This is a race thread, please take the general BOP chat to the BOP threads chaps.
