Porsche 997 911 Sport Classic 2010

Ducktails don't work on a Porsche. Well, for me visually, the ducktail looks attrocious. But other than the spoiler, I like the car. But there is some of me that is leaning towards the older one.

I think the Porsche engine already use a 2 length/stage intake mechanism

What Porsche and most manufacturers use up to now is use a mechanism that can alter the movement of the valves by means of altering the timing they open/close AND the length of their reciprocating movement.

What I THINK that Porsche is using in the Sport Classic is this:

In the intake "pipe" there is a moveable device that can close the flow of air or allow it to pass normally, like all conventional engines. This assembly is not related to the cylinder heads in any way. When the device blocks the air and the piston moves down, there is a sudden loss of pressure in the cylinder. When the device described above suddenly opens, the lack of pressure in the cylinder makes air surge inside with pressure greater than the atmopsheric.

This pressure difference between the inside of the cylinder and the environment results in the "turbocharging effect" where the air enters the combustion chamber with pressure greater than the atmospheric.

I hope someone understood the above

I also hope that Porsche is going to use this system or else I will have wrotten all of the above for nothing....

Also from what i've read the rear of the car is wider, i don't know if wider than all or just the base 997.

It uses the same dimensions as the AWD Porsches (and the GT2 - GT3 for that matter)

Well, back in 1973, they worked VERY well on the RSs....of course, all they cared about then was function, not looks...

My 1980 911SC had the 'whaletail', which I agree, is more aestheticall pleasing

Design wise though, ducktails and whaletails work on a certain car that cans actually wear it. Such as older Porsche's, Ford Escort Cosworth, and etc. etc.

Ehh, beauty is in the eye of the beholder, you know

How 'pretty' do you consider the current crop of F1 cars, then??

I have to say, this is my favourite 997 so far. that's what i'd do to a 'normal' Carrera 2S, the classic wheels and the exaust specialy.

Agreed. I'm in Porsche heaven.

What a way to send off the 997 model.

I have a feeling the 997 replacement may not look as good.

Well, to be correct, it was a fast-shot after their first idea failed at the homologation. They first planned to put the complete bonnet open, like you know it from Abarth Fiats or the famous NSU TTS, but it wasn't allowed (parts to hold the bonnet open where made at that time), so they built the little spoiler, today known as the "ducktail" to a late 911 ST and tested it on the racetrack to discover, that it works.

From Porsche....let's see...based on their astronomical charges for options etc......I'd say another 20k would get you colored accents.

Worth it.

Wait, is that in dollars or euros?

Gold.

That is also true. I don't really pay any attention to the F1, Indycar Race, NASCAR, or all those other racing thingy's. I'm just a female car fanatic.

I understood, it's like filling a vacum, the air will enter at a higher rate and bring some more air with the flow.

Priceless.

I don't even have to make sexist comments.

[Dino Scuderia]

I've never heard 'racing' and 'thingy' used in conjunction before.

She just set female car enthusiasts back twenty years, I think.

I can't help but laugh at Dino's and wwgkd's posts.
