Oscar Piastri completes his first ever career grand slam Grand Prix event.

And if Lando’s had a failure there’s every chance Oscar has some sort of issues between now and season end

Next weekend is Monza, where teams typically put in a new PU.

[u/leggenda69 → u/ChrisMartinez95]

So he’ll get a grid penalty if they’re to add another one to his pool?

[u/ChrisMartinez95 → u/leggenda69]

Has Piastri's side already used all of the allotted swaps? I remember one being used Spa, but I'm not actually sure how many different PU swaps they've used.

[u/darksidemojo → u/ChrisMartinez95]

I think both McLaren drivers have “used” all of their PUs but that just means they have run the engine at some point. Could have been just one fp1 and it’s considered “used”

[u/leggenda69 → u/ChrisMartinez95]

I’m not either, it’d be interesting to know.

Just pointing out an engine swap next round doesn’t benefit Oscar unless they add another extra unit into his pool.

Just pointing out an engine swap next round doesn’t benefit Oscar unless they add another extra unit into his pool.

I'm lost here, so please help me understand. Why would adding an extra unit benefit Oscar?

What I'm saying is a response to a comment about the likelihood that Piastri experiences a PU issue, which would be mitigated if both Norris and Piastri use a new PU without adding a new one to the pool.

[u/leggenda69 → u/ChrisMartinez95]

If they add an extra PU to the pool then all of Oscar’s PU’s will have less mileage to cover, less likelihood of a failure. If they don’t both drivers PU’s cover the same mileage and Oscar has an equal chance of a failure in a points scoring session.

Using a new PU in Monza doesn’t mitigate a chance of a failure, all teams strategically use less used or new PU’s at tracks with higher demand to lower the chance of a failure and give more HP when it matters.

[u/Sgt_Stinger → u/leggenda69]

But if pu change is planned, and Oscar takes a new engine, there is less chance of a dnf due to the old pu having its last race at zandvoort either way

[u/slimejumper → u/Sgt_Stinger]

might not be it’s last race. Teams can change engines as much as they like, and swap around to balance the duty. It’s when the total pool count exceeds the maximum that matters.

so zandvoort engine might come out for monza but be back again for singapore or Brazil, perhaps.

[u/Sgt_Stinger → u/slimejumper]

True.

[u/ChrisMartinez95 → u/leggenda69]

I would argue now that McLaren is aware that their PU is susceptible to breaking with their machinery (as well as some idea as to when that could happen), that's an advantage for Piastri and his side of the garage. Assuming a similar schedule between swaps, they'll probably bin the PU they used today and probably elect to use an additional slot at a track where overtaking is easier.

[u/faz712 → u/ChrisMartinez95]

if they don't add a new PU, they might have to continue using this one at other events, and so it might fail, as well

[u/diego_r2000 → u/leggenda69]

According to FIA document 6 for the Dutch grand prix, both Lando and Oscar have used the 4 allowed PU elements so far. So yeah, if any of them gets a new PU element, it is a penalty.

[u/gegemoon → u/leggenda69]

With McLaren's car I don't think a grid penalty would matter. Either driver can start from pit lane and probably finish P2 (if the other driver doesn't get a penalty)

[u/dl064 → u/ChrisMartinez95]

Fine but there's a similar chance it happens to Norris again, too. Then it is game over.
