Legendary Engines #1: The "Mezger" Porsche Flat Six - What Actually Does That Mean?

[@2002honda954]

R.I.P. Mr Mezger. Thanks for all the wonderful sounding six's we hear today

[@3.2Carrera]

I'm rebuilding one now. Amazing design. Strong as hell with 8 bearings for only 6 cylinders with precision dry sump oiling. Love working with it.

[@geoffclarke8934]

One of the all time great engines. Really miss my 996GT3 I had for 12 years.

[@danrook5757]

What about your ex wife

[@trance9158]

917s....the holy grail of race cars. Love the exhaust notes at the start of the video. Nothing sounds like a Porsche.

[@Rynardts]

Very timely video. Hans passed away on 10 June 2020. RIP Hans!

[@LC4Driver]

Ride in Paradise, Hans...

[@n.a1827]

Let's not forget the last version of the gen 1 turbo 997 mezger derived engine was actually also used in the 997.2 3.6 GT2 RS with 620 Bhp and the most power full road going Porsche at the time.

[@pavelprunner8855]

Jay, this shows a lot of research put into a couple minutes video. Good job man, and thanks. Keep doing a good job. :)

[@RogerBaileyOnCars]

I watched this again - well worth it.

[@mntbighker]

Love to have heard your thoughts on the differences between a Mezger and current power plants.

[@modernworldiscrap]

RIP MISTER MEZGER

[@Frapzoid]

Ich danke ihnen, Hans.

[@marcducati]

The metzger also has the robust Nikasil treatment of the cyldinders that all 911's had up to the 993 but not the 996 M96 and M97 engine. Those have the Alusil treatment that has the resistance of butter, hence the infamous bore scoring and all the engine failures.

[@benandspeed]

What a life he must have enjoyed. RIP.

[@ordersforsplitdogs4315]

RIP Mr. Mezger. You will be missed

[@mcspikesky]

In order to facilitate the delicate production of Mezger cheese a sophisticated 'dry pump' system is used to distribute the raw cheese throughout the production vessel allowing for superior texture,, cheese life and cheese cooling. This makes for the smoothest, sleekest and driest cheese in the Northern Hemisphere

[@rickc2102]

I'm now officially smarter today than I was yesterday. Cheers!

[@animalcol1]

A whole lot of smart arses here. Have a gold star, for pendantry. A great video made by someone who does being criticised by those who dont.

[@mjohannssen]

Really great video. 👍👍👍

[@peppyvw]

Aaah , you fixed it! #Boxer ↔️😉 Great stuff, keep it up. Regards from The Netherlands!

[@bertos910]

Love your content Jay, you inspired me to start my own youtube channel. Thank you for motivation.

[@JayEmmOnCars]

That's great to hear. Good luck!

[@mcspikesky]

During the 1970 LeMans cheese shortage the Porsche team, even the tea ladies, were involved in hand producing Mezger cheese. This herculean effort propelled Mezger cheese into the hearts of the French earning them valuable contracts once French cheese production restarted following the shortage.

[@brightenupcc]

Best video from Jay

[@Remyl0.0l]

This video's quality is excellent exceptional! Been following side the McLaren controversy. Keep it up!

[@flyingby3703]

An engine that I would love to see in this series is the BMW S54!

[@lunakai_360]

That's a sweet engine😌

[@flyingby3703]

Lunakai_ I test drove it in a Wiesmann MF3 once, was amazing, a lot of fun and great sound.

[@BibTheBoulderTheOriginalOne]

My favourite exhaust sound was my old Kawasaki Z1300. Silky smooth with a nasal drone....music to the ears...

[@user-el5mg4it9t]

R.i.p. Mr Mezger.

[@aboyandhisdog]

So I'm a tad confused...is the 3.6L in the early 997 a Metzger or is it different in some way? What about the 3.8? Thanks, James, great channel!!!

[@rogermo5122]

Thanks for the videos, they are really appreciated! :)

[@gregcym]

Really enjoyed this video. Could be a very interesting series. 👍

[@e36328isport]

gregcym I agree completely👍

[@iancharlton678]

………. why I done gone bought one 🎉 Overjoyed ⭐️⭐️⭐️⭐️⭐️

[@pye007]

Its that Mezger sound!!

[@rumrnr78]

I would love to put a Metzger engine in my 996 and make it a "sleeper" Porsche. Would this be possible? What would it cost?

[@MrRMC-gj4ip]

This was an awesome video!

[@geoffwatches]

Good video, thank you

[@planes121]

Mines got a metzger in it!

[@danrook5757]

Watt u got

[@HORUS9]

So does this mean my 987 boxster s has dry sump? So cool!

[@automotivetvchannel]

nice video

[@rocketn8]

RIP

[@HipsterNgariman]

Wasn't the 993 GT1 already just the rear of a 962 ?

[@jayjackson1272]

Was this taken down and reuploaded? What happened

[@JayEmmOnCars]

Yes, I corrected a mistake in the video

[@pye007]

Do you have a photo of the tea lady?

[@jehl1963]

A couple of additional points -- 1) Dry sump engines usually make more hp than an equivalent wet-sump engine because they reduce the oil spray (mist?) In the case that causes drag on the crank like how riding a bicycle in the rain takes more work than riding in the rain. 2) As a derivative of the 962 engine via GT1 race car, the GT3 engine was still of the technical lineage of the Air-cooled 911 engine, just one where pretty much every part and assembly was incrementally changed over the decades from the original 2.0 liter air cooled 6. This is why you can still retrofit some of the GT3 engine parts onto an air-cooled 911 engine. The oil pump is one thing that comes to mind if my memory is correct. The 996 Carrera engine on the other hand is a completely new design that shares nothing with the air-cooled motor aside from the words "flat-six".

[@raymondlim1485]

Legend. RIP

[@SB-vb8ch]

Can you clarify the "180 deg V12" rather than "boxer" comment?

[@julianb1474]

I got schooled in this after the previous upload of this video. The comment that the V12 was chosen for "packaging reasons" with no explanation as to what that meant was what caused some head scratching. For the difference in design, see wiki.en.wikipedia.org/wiki/Flat_engine It would seem that a V12 could be a little shorter. Because of shared journals the crank can be shorter and the cylinder offset reduced over a boxer design. I'd have thought the differences pretty small, but there you have it.

[@andik.4235]

@@julianb1474 And a shorter crankshaft is simpler to handle regarding bending, because it is stiffer because of the shorter length. So it can be build lighter and the engine is faster picking up revs. Ferrari Testarossa engines were also 180 ° V 12 engines.

[@mntbighker]

Singer Williams 911 sound...

[@kyleabrahams2696]

Wasn’t this uploaded yesterday???

[@JayEmmOnCars]

Yes, had to make an edit for a stupid mistake I didn't notice

[@fg87fgd]

Unfortunately this is in German, but 9FF does an incredibly good job in getting the weaknesses of 996 & 997 engines and strength of Mezger engines across. Here is how they'll switch a simple 997 Carrera into something quite different: kzbin.info/www/bejne/oHLbhYh8eKqMldksi=7oRqWxI-mDd983NE

[@990v6]

These guys seem to be frauds just check the detailed reviews. It’s shocking

[@mcspikesky]

Mezger cheese is renowned for its sleek looks and excellent protein levels compared to other non water based cheeses.

[@120M]

997 CARRERA S has also this engine?

[@danrook5757]

What year

[@hmk911]

None.

[@matteightytwo]

A boxer IS a 180* Vee, isnt it?

[@JayEmmOnCars]

No, there is a difference

[@matteightytwo]

@@JayEmmOnCars firing order difference?

[@andik.4235]

@@matteightytwo In firing order and with a Boxer configuration both opposite mounted pistons move outwards at the same time and move inwards at the same time. They have not a shared joint at the crankshaft like an 180 ° V engine. There one piston is moving out and the other one is moving in. And the vibration harmonics are quite different. A boxer for example has no first order oscillations.

[@matteightytwo]

Nice, everyday is a school day!

[@ahrred3127]

Deja Vu

[@barrybritcher]

What was the mistake

[@JayEmmOnCars]

I called the flat six a straight six

[@mcspikesky]

MEzger is a type of cheese which does not use water in its production. Video over.

[@beardmechanix1642]

Also worth mentioning how the Mezger needed to be routinely rebuilt after hard driving of up to 40k miles. The Mezger engines also suffered cooling issues as well as bore scoring! My only hate when it comes to Porsche Fan Boys is the whole “Mezger” name dropping. However, the engines were far from perfect. In the 997, they show their age. It’s not a great match for such a great chassis. 997.2 were better all round road cars when the DFI engines were introduced.

[@jeanpaulceulemans9973]

total nonsense, the only thing better with the 997.2 DFI is the longer rod/stroke ratio, all the rest of the engine is less durable and less tunable, including the rods which were strengthened again in the 991 turbo. Some early 997.2 turbo engines even got stuck pistons due to the cylinders shrinking from residual tensions in the block. Porsche also recently dropped the Alusil for iron plasma spray coating but most engine builders still agree that the Nikasil of the GT1 derived engines is still the best in the business for wear resistance and temperature cycling. But even in the exceptional case of bore scoring, the wet liner can be replaced without any machining on the block When the cooling pipes are fixed, the 996/7 TT engines are almost indestructible

[@beardmechanix1642]

@@jeanpaulceulemans9973 nonsense? And what were the massive issues that problematic on the gen1 997 Mezger? Bore scoring and IMS Bearing failure! Sorry, defend the Mezger all you like, the DFI was a better engine for the 997!

[@jeanpaulceulemans9973]

@@beardmechanix1642 You have no clue about porsche engines whatsoever now do you? The problems you're talking about were with the open deck locasil engines in the Carreras/Boxters and these are totally unrelated to the TT/GT closed deck wet liner Mezgers which have no ball bearing on the IMS and nearly indestructible Nickel Silicon Carbide cylinder coating

[@jeanpaulceulemans9973]

@@beardmechanix1642 The first gen DFI 9A1 Alusils had casting stress that could lead to oval cylinders and catastrophic piston lockup Although much better than the M96 junk used in the Carreras they're not even close to the mezger in durability The second gen DFI 9A2 dropped the Alusil alloy and switched to a tougher alloy with iron plasma tranfer cylinder coating which is still inferior to the Mezger cylinders All serious engine rebuilders prefer the wet liner nikasil cylinders solution of the original Mezger engine

[@beardmechanix1642]

@@jeanpaulceulemans9973 this is the problem with Porsche fans! Slate a Mezger engine and be doomed for the rest of your life. Doesn’t matter what version of the engines were problematic! The more they evolved, the more issues came along. The engine was dated for the 997! The chassis’ were superb! DFI was better suited to the 997 chassis.

[@pokiou]

so Hans contributed to the 996... who came up with the stupid IMS roller bearing then ?

[@haydentakara4369]

I’m pretty sure the 996 turbo didn’t have the issue and had the mezger engine, while the regular carrera had the issue but no mezger

[@pokiou]

@@haydentakara4369 yup that's right only the c2 c4 mk1 and mk2 and also the 997's had IMS issues. But still i wonder who sat in the meeting and thought that this was a good idea. Even though i've done 194,000 km on my 996 with original engine and im truely not worried i just feel its the 1 thing that deters the purchase of what is actually one of the best drivers cars.
