Porsche 997 - Development Curve - Page 3

SebringMG · 5 Jun 2007, 09:42 (Ref:1929181)

Hmmm homologation of a Cayman for racing would probably be dependant upon Porsche giving assistance - which they are unlikely to do

Engineering wise i think it is possible (most things are) but difficult without Porsche assistance!!!

Satorian · 5 Jun 2007, 15:28 (Ref:1929431)

As said above, the Alzen brothers field a Cayman in the VLN (Nordschleife endurance racing and 24h event). As far as I know, their latest plan is to fit in the Carrera GT V10 in there.

Does anybody know whether manufacturer's agreement is required for the FIA GT? Didn't Ford say the Ford GT will never be raced, yet we have the Matech GT's racing in GT3? (This aside, there's of course the brilliant Ford GT in SuperGT GT300.)

Factory approval to homologate a car isn't required anymore, just think about Prodrive Maranello

As i understand it the cars need to be homologated....does not have to be the manufacturer that does this AFAIK

cmk · 5 Jun 2007, 18:38 (Ref:1929585)

Not to mention that, as I understand it, homologation for GT3 is a different kettle of fish to that for GT1/2. Probably explains some of the confusion here.

Martin Haven · 5 Jun 2007, 22:13 (Ref:1929748)

So, what are we saying?

Porsche will not go LMP1, so as not to step on Audi's toes - or because they think diesels suck (like the rest of us...)

Porsche won't help Alzen develop a 997 Cayman (let alone a V10 one) in case it looks fast but silly

So, I'm guessing that the W12 Maybach LM GT-R Diesel is right out then???

Damn, that would have bored Aston and Chevy to death

Satorian · 5 Jun 2007, 23:41 (Ref:1929790)

I think the Alman looks quite alright, stalking the 997 GT3.

Porsche will be back in LMP1 and winning Le Mans soon enough, just you wait and see.

Audi might have left by then, but it would be a Porsche Petrol vs a Audi Diesel and they would not be stepping on each other toes because it is a different fuel supply and marketing for different things.

The 997 RSR anyway, there will be some updates comming for it soon, as we still can't match the pace of the Feza's yet really, so Porsche are working hard as usual to put that right.

As long as the petrol engine is allowed to compete on an equal footing, then let's get to it!

They had better not take too long, I don't think I can bear it for much longer!

Sean, is the latest spec 520 hp one of the upgrades you are referring to?

I think it looks good, nice pics, What class was it competing in and how did lap times compare with the GT3? I would like to read a full report please (in English I am sorry to say) where do I find it?

Thanks for that, fascinating stuff that makes me want to know a lot more about the state of tune of the engine, which gearbox they used and the rest of the spec in comparison with the 997 GT3 car. Where is the next round of this series, we don't see much about this in the UK unless I am missing it which is always possible. Any info dsced?

Spyderman · 7 Jun 2007, 11:44 (Ref:1931138)

The next round is the 24H Nurburgring.

Satorian · 7 Jun 2007, 14:01 (Ref:1931260)

Which happens this weekend and an online stream is available at http://adac.24h-rennen.de/live/streaming.html

They will show race footage, interviews and on-board shots.

by 2010? what updates? source?

Why does this 997 GT3 RSR have a rear diffuser? I thought the 911 couldn't have one due to the need to cool the engine or something.

doesnt look like a propper diffuser to me, just looks like 4 virtical planes stuck to the bottom of the rear undertray which all the 997 RSR's have.

bil588 · 7 Jun 2007, 22:52 (Ref:1931790)

well does anyone have underside pics of the new car?

is it true that the 911 can't use a full rear diffuser because of the rear engine?

it cant use a full rear diffuser because it isnt allowed by the ACO, FIA

EDIT: here is a pic of the rear of the car

That seems to be the Manthey Porsche for the VLN and Nordschleife 24h. Their rules regarding aero devices are different (and more diverse according to their many classes) from FIA/ACO regulations. Chances are this isn't FIA/ACO spec.

Spyderman · 8 Jun 2007, 09:05 (Ref:1932039)

Also- there are no restrictors.
I think that this explains the 520hp spec 997

Spyderman · 18 Jun 2007, 11:28 (Ref:1940709)

So it seems that the 997 still has something to give.
Although this year's qualifying sessions were not really indicative of the ultimate pace of the cars, the 997's did manage to beat the Ferrari's (both on the 1st and 2nd day)
They went on to post the two fastest race times and registered the highest top speeds on the Mulsanne straight.

Le Mans is obviously a track which suits the 997.

prototype · 18 Jun 2007, 17:16 (Ref:1940905)

I also think the Ferrari 430 is a 12 hour car right now.

Two 997s did and did not finish the race while two F430s finished the race and three didn't.

cmk · 18 Jun 2007, 20:30 (Ref:1941059)

And it is fairer to say that, if it is indeed fragile, the 430 is at least an 18 hour car.
