I don't know for a fact which of those 24 hour races is "supposedly" harder on an engine and it sounds as though you don't either. Anyway, all I said was that 3 9A1 engines entering and 3 finishing the Daytona 24 was a good sign. That's certainly indisputable.

3 different teams, Napleton Racing, Bullet Racing, and BGB Motorsports entered 9A1 Caymans with 3 completely different sets of drivers. They weren't all part of the same organization under team orders to take it easy. The Mazdas may have dropped out, but the Porsches were running as hard against each other to win as anyone else out there. They weren't on cruise control.

+1 and they beat some of the Cup car teams so that's not really cruise control.

The banks at Daytona are as hard on any engine, probably harder then the Ring. The problem is Porsche has never backed a Cayman and probaly will never. Maybe the 960 will get factory backing.

Default Mezger question

I've been reading this long post. People say the Mezger engine is old and does not have direct fuel injection (DFI). Why can't DFI heads be created for the Mezger engine? The Mezger engine is just a block. It's been adapted from air/oil cooled to liquid. What is its short coming? Weight? Or is it really just about cost to produce? If anyone can explain I would appreciate it.

Back in the day, the 12-hours of Sebring was considered as tough or tougher on cars than the 24-hours of Daytona.

I would have thought the same, with engines at full thottle for extended periods a couple of times a lap on the banking, and centrifugal force making lubrication problematic. Regardless of whether Porsche backs Caymans or not, I still say the fact that the 9A1's survived 24 hours is a positive and shows they have endurance potential.

Yes. I think that was due to the extremely bumpy surface of the old runways and hot weather as much as anything else.

Cost
Emission
Also hard to get more displacement

Speaking of enduro races - does anyone know of an article/documentary on the .2RS running the 24H (driving to and from the track)? I had no idea that this happened....value of my car just went up in my mind.

24 Hours at Nurburgring endurance race in 2010. Roland Asch, Patrick Simon, Chris Harris and Horst von Saurma were the drivers. 13th overall at the end! Driven from Weissach to the Nurburgring...and back. Was on display at the Porsche Museum in Zuffenhausen afterwards. Never cleaned up or washed since that race!

Crazy. Surprised it didn't get more press... especially with Chris Harris involved.

Pretty cool story at the time :-)

I think a Swedish outfit did the same in the 2012 24 hr. They also did very well! The 3.8RS is a very high mark for Porsche to beat in terms of overall package.
