Sames basic engine, not a lot different between the two beyond displacement.

What's your point? They ran within the rules and they filled the podium. More than can be said for all those factory supported Metzgers.

Big win for Porsche Motorsports NA though. They sold a ton of parts.

Porsche doesn't want the Cayman to beat up on the 911s so they won't let them run a premium engine. Have to keep the pusher buses going.

Great race, including the other two classes.

Yes, same for me.

Is the DFI engine the newer Porsche engines without the IMS?

TIA,

Can't recall where I read it but the GX Caymans used the 3.8L X51 version of the 9A1 direct injection motor. Same basic motor as the 997 GTS. It doesn't have an IMS like M96 and M97. But it's not the Metzger design as used in GT3s, GT2, TT. Not claiming to be an authority. Just what I have read.

Yes. The Direct Injection Engines (9A1 series) replaced the M96 & M97 engines. This engines has proven, so far, to be more durable. Time will tell but it seems to be a much better engine.

Not to be rude, but we did that. In 2010 and 2011, the 3.4L DFI Cayman S that we built and developed in the Continental Tire GS class beat the port flow EFI 3.8 997 from TRG driven by Pumpelly, almost every race. NOW, given that Pumpelly drives for us, we know he's no slouch and is probably one of the best drivers in the country in a street stock 997. Top 3 easily. SO...again, not to be rude, but we alreayd did that!

In order for a Cayman S to not be a moving chicane with a DP passing at 190mph, there's no way a 3.4L is up to the task. You need a 400rwhp variant like the DFI X51 GTS motor.

Great Job, John, watched it all !

Congrat's John on a great race.

Without taking anything from the excellent runs that earned GX podium spots...
Assuming or suggesting that a podium finish (in a different class) proves hardware superiority is flawed. A trio of Mazdas that completed less than 150 laps COMBINED is not comparable to the effort put in by Audi or even Ferrari. (the ONLY car that a mazda beat was the viper) 8 Cup cars beat the GX winner.

Congratulations to Napelton, Bullet and BGB!

Do they get a Rolex "Daytona" watch or a "Tudor" by Rolex watch.

Adam@Autometrics

I honestly meant no offense to you. I know what it takes to prepare for and complete a 24. Especially considering the other challenges you guys were dealing with that weekend. Things that were not your fault, but you handled them very well regardless. I apologize if I came across as critical to you or the other Cayman teams; it was not my intention.

The competition among the Caymans was certainly no joke, but the Mazdas were. The sentiment that the Porsche GT teams or hardware were lacking is misleading. Perhaps I was reading too much into the comments, but to underestimate what the GT Porsches and the Audis brought to the table is not fair, and I was compelled to say something.

The durability of the Caymans was truly impressive. I did not doubt that it could make the distance, but I am surprised that all 3 did. Again, congratulations. I understand the difficulty and accomplishment better than most.

What was the GX class?? To me it looked like a bunch of Cayman's in a class of their own.

Black Sea RD

Thanks for the clarification on the DFI engine zedcat and stuttgart 46!
