Ferrari F138

[KennyBama]

The F138 simply has me confused. From race 1 until now the trend has been a downward spiral. I hope the new wind tunnel makes a difference. Or maybe mgt should be realigned.

However, you are right, why it's taken them this long to incorporate something which their data obviously showed was faster is a bit ridiculous.

Could it be that it is up to the driver's to utilize that?
Webber is slower than Vettel because he cannot use the EBD-like effect like him.

I think they run equal rake.

So they introduced the longer exhaust in Spain. Now we are nearing the end of the season and they still don't have a clue which one is better.
Ferrari should stop wasting times on solution which are redundant for next year. They should be focussing on testing 2014 parts.

very true , this iterative development methodology is not working. how many races they need to identify which version of exhaust is better.they have already wasted 2 full championships in understanding flow behavior around car. it looks like season starts well but over the season , when updates dnt work , they start questioning the philosophy of car. rest of season should be used to assert the data coming out of new wind tunnel.

I think 2nd in the constructors' is still quite important to them and, without a more stable rear, they're not really looking fast enough to keep it. So I think they still think there's time to be found by having a better exhaust solution.

However, you are right, why it's taken them this long to incorporate something which their data obviously showed was faster is a bit ridiculous.

Hmmmmmm, I'm gonna go out on a limb and say it isn't that simple. Likely that long exhaust has some attributes that are different that the shorter exhausts which might make them more or less appealing on different tracks.

I'm not sure it is any different that running different wings at different tracks.

Did they ever run it in the race though? Maybe Canada, when they had very little dry running to assess the virtues.

I think if it were ever a track-specific alteration, we would see it being run in the race for the tracks in question. Also, do other teams run alternate exhausts depending on track? Doesn't seem like it to me.

Maybe the size of the helmholtz chamber could be track specific, but I don't think that relates to the length of the exhaust in this case, rather to the bulges we sometimes see.

I think you miss a point. I truly believe that's what they are doing: understand car behaviour in order to confront data from track and simulation. It's pointless to start working flat out on 2014 parts if you are not able now to understand the numbers you are seeing. so first they need to sort out these problems of correlation once for all, and then move on to 2014 project.
ok they won't be using toyota's WT anymore(hopefully), but they need to check others tools of CFD etc

It's not a matter of developping or not this year's car with specific parts aimed at performance: it's way beyond that. It's a structural problem. IMHO

Did they run asymmetric exhaust in Singapore then one was shorter and other was longer

No, the exhausts were the shorter. The asymmertry is about the body:

[diffuser]

blogf1.it says that they've never tried the new diffuser with the long exhaust. They claim that the longer exhausts gave them higher but less stable downforce (diffuser sealing problem) with the old diffuser which they hope to have resolved with the new diffuser.

I agree whole heartedly. The Beam wing is gone and exhaust gases but the rear wing will still be there and so will the diffuser. That makes the diffuser even more important. They'll try to figure out how they replace the heat from the exhaust gases...

Who did that nice 3d model?
Ah, it's Juan David Barrera himself

[timbo]

It does not show what to o with cooling, which is a big obstacle.
