it wouldn't surprise me if they know it can't make it through the next race weekend and have a convenient excuse as to why they'll take yet another penalty.

Just take a look at the picture and you will see the angle between the Rear axle/gearbox/Aileron and the rest of the car.
In between is the engine.

Though, how many accidents have cars been in where the engine hasn't been damaged? I'm actually genuinely trying to remember and can't off the top of my head think of what bigger crashes we've had this year. There isn't for me much reason from the accident for the engine to have been damaged is there?

Just look at the picture that Thunders posted. Prolong the centerline of the car and the centerline of the exhaust. You do realize the engine is part of the chassis, do you?

Look at the slow motion video. The car makes a sidewise impact with the rear left tire first, the chassis is not made to cope with a 34G impact (I read that somewhere, can't remember where thoug). After that RAI car hits the engine from the other side with his rear left again. Saying that an engine should be able to cope with this is nonsense.

Also, engines getting destroyed didn't use to be a problem since there weren't penalties.

Did Button even get a chance to serve his penalty before retiring, seriously, thinking the penalties matter at all to Mclaren is ridiculous.

It doesn't 'really' matter, I get what you are saying, but it makes a difference. Well, if they actually improve and the only thing they want to do is test, it's still better to race at a competitive position to gather data than to have to fight through the field. On top of that, it's not fair to get punished for something you did not cause at all.

I just didn't think it was a particularly bad crash for the engine. Breaking an exhaust or body work isn't the same as hurting a big metal block inside the middle of the car. Also yes last year in particular much bigger crashes happened without new engines being required the next race. As for Kimi hitting the engine again, the engine isn't in the side pods and we've seen far bigger shunts and engines survive them. That crash was dramatic because the car went over the top, but having a sidepod get smashed shouldn't automatically cause the engine to fail.

I'm merely saying with 90% of the PR coming from Mclaren/Honda about how the engine is definitely great and it will be unleashed soon... a team and companies so willing to make excuses, it provides a convenient excuse for saying this new engine isn't our fault. Since Canada, well, there is no chance they'd take this weekends engine and finish the next race with it.

As for racing in a competitive position, meh, firslty they aren't competitive without time penalties and with them they get clear air and less traffic. 90% of the running they've done this year without penalties they've still been in clear air with a generally huge gap for the majority of the race between third slowest, the Mclarens, then the Manors another huge gap behind them. Where the big gap with no cars around them is can't possibly make a realistic difference. IF they aren't finishing the majority of races due to reliability and outside of Monaco have next to no chance of finishing in the points either, then penalties aren't going to hurt them. Since the latest engine update, they've been using what 1.5-2 engine parts per weekend and haven't got close to finishing a race.

I'm not having this discussion. There was no PR related to the engine needing to be replaced. AFAIK this is only fans discussing the possibility. You don't have to hit an engine directly to hurt it. If the exhaust bends causing a screw to pull the thread out of a mounting hole the block might be beyond repair. Just look at cracks in buildings when someone is constructing a house next to it, everything is connected, so there is a possibility. You can't deny the sun. I'm not saying it is like that, neither can you say it is not like that.

Apperently there is no more interest in a second team?

/[OT]...what idiotic rules we have in F1/[OT]

I agree with you. Damaged PU due to an accident (that wasn't even Alonso's fault) should not count. It is not due to reliability or driver error, Alonso was in a wrong place at the wrong time.

If Alonso was the one causing the accident, then the engine must be taken out of his engine allowance.

I agree with you.....
I can't see drivers creating accidents to get new engines.

So I say either way you should be allowed...

How do police that ? any time you have an accident you can change you engine ??? They happen often. Will the team have to prove to the FIA that it was damaged from the accident beyond repair ? If the PU was on it's 5th race is replacing it with a BRAND NEW PU fair ?

The other issues is the poorer teams will block that change. They don't have the money to pay for more Motors. It easier to budget for 4 motors for a year...than 4 maybe 5 or 6.

So I also agree with them as well. I want to see the small team competitive not just white space.

The "raison d'être" of that rule is to keep costs down. It is why it is what it is. So from that stand point it makes alot of sense.

Why do the smaller teams need to keep costs down ? There are probably alot of reasons ... One reason is they don't get as much money from Bernie and his friends.

It's a vicious circle.


My point is that it's easy to take a rule out of context and complain about it. The solution isn't gonna be that simple and everyone is b*tching about complicated Rules

That Honda compressor is still bugging me.

I am I alone in feeling that none of the speculation by pundits and forum-jockeys about what exactly it is seems to quite hit the mark?

[OviJohn]

Hi all!

Concerning the whole "Axial turbo" speculation, did anyone hear the sound of it when JBs car stopped in FP3 last weekend?

This is how it sounded from his on board as the car went to a halt:

Anything special or different there?

Note:
As a Mclaren fan, I´ve been following this thread for sometime. Im far from being an engineering expert, so I do my best to follow all the interesting views and analysis posted by most of the people here. Thanks in advanced for any insight

I hear two things the motor generator (the electrical sounding noise) and the turbo. The buffeting is from the turbine and the whine is from the compressor. The overall frequency of the turbo sounds rather low pitched.

[PlatinumZealot]

Here are some more sounds for ya.

Sounds like an S2000 with clogged injectors and a loud ricer exhaust.

So basically theres just nothing unique or overly interesting about how it sounded.

Thank you for the insight and the video. The motor sound has gotten so much better since winter tests.

Hi i just want to ask do honda f1 power unit have vtec technology in thier power unit or hidden secrets in thier ice? Tnx

I wouldt strongly doubt vtec would be of any use in a F1 engine, as these engines idle at ~4000 rpm and dont dip below the standard 8000rpm with around a 4000rpm working range due to the fuel flow limits, I would think the cam timing change (If they still have cams but I do not have a source on this) that VTEC performs would be fruitless.
