With DFI the combustion temps are lower so in turbocharged applications you can do more with boost than an efi mezger which needs to offset the higher combustion temps from adding boost. The 9A1 DFI produces more power per cc, is more efficient as a performance engine, and is simply more technologically advanced as an engine on a number of fronts, a clear step forward on all counts. i.e :9A1 has 40% less components than Mezger making for less complications/problems, weighs less, the new design allowing a lower center of gravity in chassis. All clear positive steps forward.

The age old argument the Mezger is tried proven and tested and the 9A1 isn't, is getting old along with the 997.1 platform in general.

9A1 has no history of premature failures least of all suffering from the same problems mezger suffers (i.e IMS shaft failures etc) note: 9A1 has been in the market in large numbers for some years now...purring away reliably, fuss free with better performance and all round efficiency.
Sure, race teams will always work with what they are accustomed to and, what they can get parts readily for at a cheaper price (usually for when it pops from over-tuning it without replacing the "rods" and other hard parts lol).

If there are any comparative weaknesses between both engines it is purely in the rods of 9A1 which are marginally lighter. Like big deal! How many tune the engine to a level which will bend rods anyway?...and those that do usually regret it at one point and/or sell the car off for reasons previously mentioned i.e it becomes a pig to drive beyond short blasts, becomes garage queen accordingly.
The whole Mezger is "detuned" story and 9A1 is "tuned out to the max stock" story is pure unadulterated fantasy, evidently based on die hard emotion with zero supportive facts beyond the weaker rods story (which is a thin argument at best).
Die hard's raving on about Mezger's racing history/pedigree as if they are driving around with a full blown Lemans race engine under their hood is laughable, as fact is a proper Mezger race engine has so many different up-rated internal hard and core parts than the street Mezger engine (save the basic bare block) it may as well be called a different engine model, yet certain owners of the street Mezger claim the same status as the race variant LMAO! You guys crack me up. Seriously. Who are you trying to fool? I mean just look at the differences in the pistons, rods, oil pump, crankshaft, valves, springs, camshafts etc..so why bother embarrassing yourselves by even comparing the two variants! Oh, but the block is the same lol so yup it's the same engine lol
I think the best cure for some guys is to actually get the keys to a new 9A1 car and take it out for a day, then get back into .1 mezger and deal with the fact the new car is simply better performing everywhere and not just down to the pdk box. Times have moved on boys and to much greener pastures....

PS. Forgot to add a DFI engine in general is far more costly to manufacture than a conventional EFI due to the requirement of more robust components, which kind of blows the argument that the engine is weaker and Porsche changed to the DFI to save money on production lol.

Nostalgia is the only valid argument for a stock/bolt ons street car.

Grab the keys for a day and put one of the 9A1 engine'd cars through its paces and then tell me all about it ok. Porsche is about accel times and lap times both of which exceed the Mezger where the new car/engine is concerned. Forget the hp increases not being to "expectation". Its all meaningless when the the new car is eating the old car for breakfast. The new DFI engine is capable of much more yet doesn't need to do any more to spank mezger and blind freddy can see that. That's all that matters. While you guys are tripping on the nostalgia of an engine which in essence is vastly different in terms of internal parts than what your street engines have, the new street car has left you in its dust.

Game over.

Sitting must be difficult for you.

You once used the abbreviation "LMAO." If you've been "laughing your *** off" to some of the responses to your posts, then you must have difficulty sitting. Your accusation concerning "direct insults" completely misses the mark.

Everyone working on these cars will tell you the .2 is better from Tym S, To AMS, To Vivid and more. Do you guys even work on your cars? Or they just trophies with clean DME reports. lol

Pathetic really. Must be that time of the month I guess.
