It's not affecting Lance....

He has a different seat.

I don't think you're understanding Krack's words properly.
The seat for both drivers are both in a more extreme inclination due to the aerodynamic design direction by Newey. The pressure points on the driver has shifted because of that. Alonso's body can't take the bumps anymore when so reclined and they will now make his seat more upright.

Age could have something to do with this. See Lewis and Alonso in 2022 crying for their backs.

They still have different seats, and very different body proportions. Something might be poking at Alonso that isn't for stroll. More likely than being too old for discomfort... No one said, the seats aren't inclined...

The other thing is FIA on June 1st will change the CR tests. So the Canada HP was Mercedes's CR edge last hurrah. We will not notice until Spain, because of the nature of Monaco's track.

I highly doubt anything will change... Either because they didn't have a trick in the first place, or the test is useless at filtering with its lukewarm 130°C temperature.

Cylinder Pressure Sensors: Every F1 car runs highly accurate, mandatory pressure transducers inside the cylinders.

Irrelevant. (And I also think it was removed for this year) At 130°C it wouldn't have been likely to show anything.

[mzso]

so if newey doesn't turn up this weekend. safe to assume that he's been ill for several weeks is true?

He's not team principal anymore. And they design the car at the office not at the racetrack.

It wasn't removed, they banned the the frequencies used for pressure verification.

I can see where just heating the PU to 130C in an oven, then performing a pressure test, isn't gonna give you the temperature variations that you normally see in a Piston head and combustion chamber under load. So I am not sure why the other teams agreed. Maybe it was a trade off for getting a test while the PU is running for next year?

Still don't understand how they can come up with a rule to limit something but not think of a way to test it BEFORE implementing it. Then, in doing so, create an artificial imbalance in power and benefit a team for breaking the rules.

The reports say he works mostly from home but he does go into the office.

I'm not convinced this will be tested while running next year. The rule for next year still says it will be tested at 130C, just not additionally at ambient temperature as will be the case for the rest of this year.

It is geometric compression ratio so anyone speaking about pressure sensors is crazy or just spouting tripe.

This was my thoughts as well. It won't show anything of major interest even at those temps...

The loss of ability to use those pressure sensors in every cylinder for highly accurate combustion readings to tune the operation of the engine and the reg enforced drop in compression ratio basically annihilated Honda's combustion design. It can't safely operate in the manner it did without those sensors or at a much lower CR, let alone both. And god knows how difficult this new fuel is to vaporise or just in general have any properties desired for what they were doing last year. The avenue they went down, was outlawed in every single metric. They caught the nasty end of the stick with these regs
Being 60-70hp down on a circa 500hp engine formula is more than significant. And I genuinely believe the above is why. They are effectively being forced to start again with combustion tech ideas.

[ispano6]

Is it widely accepted that 3d printed piston crowns is what allows for the compression via thermal expansion? And is there any rule actually banning that construction? As long as the prescribed test pass, it's ok?

Another major change that came on June 1st was the additional "Any component, assembly, mechanism, or integrated arrangement of components that is designed or functions to increase the compression ratio in operating conditions beyond 16.0 is prohibited."

So while before June 1st, you could legally make the CR as high as you wanted, as long as you beat the test. After June 1 that is no longer the case. It is now illegal, regardless if you pass the test or not. Meaning if you at some point get caught, it could have ramifications on races all the way back to Monaco 2026.

Thanks!

Anybody who says such things has never performed a simple compression test nor studied cam phasing in an engine, and pretends to know how a cylinder fills and compresses with air.

Yep. I thought and hoped this 'discussion' had ended but seems like not the case. As to pressure sensors, per the 2026 FIA Technical Regulations:

5.3.7 In a Cylinder Head, only inserts approved by the FIA Technical Department will be allowed.
The total volume of the inserts listed in a. to c. below cannot be more than 3% of the total
volume of each Cylinder Head and these must be confined to:

a. Conventional valve seat inserts
b. Conventional valve guide inserts
c. An insert concentric to the spark plug axis with a maximum outside diameter of 15mm

An additional allowance of 1% of the total volume of each cylinder head is permitted for
inserts other than those mentioned above, but none of these inserts can be exposed to the
combustion

That's why Ferrari was disqualified from the 2017-18 seasons, right? Hah! Nope...
As long as they can't test and prove it, it's a free area of development, no matter what the rules say.

Anyways, if you look at the ICE HP difference, it isn't the deferentiator. Nor is it why Honda don't have the power to accelerate the drag that the car makes at 262 KPH to 272KPH without the aid of the MGU-K.
