Not street-legal, only available to order Stateside from PMNA...

great!
now where do i get one?!

Any word on the $$... Or more specifically how much more do I have to bring to the table after I sell my race car for this!

To me this hilarious and tragic at the same time.

This is the very first part from the 991GT3 that will be race proven....not the motor, etc. UG...what's wrong with the GT3 9A1 - me thinks it's the elephant in the room. No one is talking about the volume of track failures that have happened already from fires to completely seized motors (well at least what I've seen with my own eyes so far) It's been nearly...how many years now...at least 4 and nothing on the track except for some brave privateers. There are some dynamics at play that I don't understand.

The bantering of a bord person in a Chicago bar...

I'm at the point of sitting out the 991GT3 and spending my FCF on another air cool project :-)

Kind of sad that you can't get one as a ready-made track car and that you _have_ race in the series...

brake dust

Yes. That's the issue you're going to have when you try to turn a production engine into a race engine.

The Mezger was fully race proven before it hit any road cars?

Shake - Was it malfuntion of the motor? What other failures?

ShakeNBake

Out of respect for the owners, since Porsche obvious does not want people talking about it, I can't share any details. The only reason I know is because I happen to be there when it happens.

The road going Mezger had a lot more "silly" issues that led to engine replacements, in all fairness.

The more I think about it the more I think I'd get more personal enjoyment out of building something in the spirit of the historical porsche race cars for the street. $ for $ the 991GT3 just isn't exciting to me. GT4 is very interesting however!

This is an interesting point. The fundamentals of the Mezger design go way back with the split case design, dry sump, etc. The newer models are more closely related to the GT1 engine design.

Most of the "quirks" in the later Mezger engines are well known, and related to water cooling pipes and cam timing adjustments. I'm going to assume that had the platform continued these 'quirks' would have been iterated out as failure components. The cup car models of these engines that don't have some of these complications (cam timing for example) have shown to be quite reliable.

And to answer the above question, the "mezger" engine that is closest to the later street and track GT3 were raced first in the GT1.

That all said, the 9A1 is a necessary evolution. Talking to an engine builder that has experience ripping these apart and building/rebuilding them, he appreciates the engineering of the 9A1, it is a LOT simpler, less parts, faster to build, more elegant design. The turbo engines he's built have made very big reliable power. The Mezger is a lot more complicated, maybe "over engineered" and for him, the 996 and 997.1 are the best of the bunch, very robust, reliable platforms. Unfortunately he has not yet torn into a 991GT3 block yet...

If porsche decides to stick with the 9A1, it will get great, but we all know how porsche engineers, slow, steady refinement and iteration. It will take time.

don't worry
Germans are slow learners
I'm
confident that in 30 years 9A1 will prove to be reliable.

sharkster

Completely with you... Lost count how many GT3s I've owned but I'll tell you straight up the 991 isn't one of them. Don't get me wrong it's super fast, technically blah blah but just doesn't involve enough of my body, mind and soul Like skynet making me look fast instead of driving a fast car ****ty like I do GT4 is interesting however it's still got rear struts, boring engine etc... and not got the magic of a mid engine NSX or Lotus....

Nizer

Number floating around at the moment is $120k for car +$20k for spare pkg.

cscrogham

It'll be way more than that, I'm saying more like $175k landed and you will certainly have to commit to run the series.
