ATI Harmonic Dampers for these cars

Ive used ati on ls engines and yes correct

However its a ferrari
Pretty sure they know what they are doing

I bought aftermarket sway bar links for another car
Lifetime warranty
10000km later worn out
So much for lifetime warranty

Aftermarket is rarely better there is a reason you buy ferrari
Its engineered performance

 

The 360 engine is internal balanced where by changing a part like that won't affect the rotational balance.
That being said is a part like that far superior then a mass production part that ferrari has on the shelf for there f131 engine. I have only used fluiddamper for my old-school builds.
ATI is a great company and could it help with harmonics in the engine. That is a great? Would you feel better or make you sleep better only you would know. But like any internal balanced engine it all lies on the Quality of the person doing that job.
Would I want one.. sure why not. Billet ,sfi approved made for high rpm. I think it's a win for all. Now the hard part is if they would even consider a run of the mill to make them.

 

Don't do it. When I build engines the crank, damper, flywheel, and clutch are sent off to be balanced as a complete assembly. Ferrari are the same: it's why on the F430 the clutch must be fitted with the yellow marks aligned to a specific position in order to keep the rotational balance in sync.

Bolting on a new part that wasn't balanced or designed as part of the original assembly is most likely not going to yield a positive result - especially not on a high RPM engine.

 

^^^ this^^^
I'm trusting that Ferrari has internally balanced my engine and are probably pretty good at it. I'd rather put my money into other mods.

I can tell you that I have a '37 Cadillac coupe street rod that has a 1970 Cadillac 500ci engine in it. It is internally balanced and does not have a harmonic balancer from the factory. It seems when an engine is built with acute attention to all details and specs it can last a good long time and run smooth without one. I once had a 472ci (same; no balancer) Cad engine that ran smooth and great for over 200K in a '49 Caddy street rod.

 

Probably some combination of those. I'm far from the "OEM is always best" type, and the stock setup probably isn't perfect, but I have faith in Ferrari on this one. The engine seems durable for what it is, and with the low production numbers and even lower number of people who would try this, I think it'd be difficult to prove anything and make a business case to manufacture it. The stakes are too high and I couldn't see myself buying one under any circumstance.

 

So you think the 360 is external balance. Where doing assembly they need all parts from the flywheel to the front balancer.
Internal does the opposite where they don't use those parts. Most cars built from the 2000 onward are Internal.
My 66 ford mustang is external
But my 2012 gmc with a LS motor is Internal.

 

It's worth clearing up some of the concepts: a crankshaft pulley with a rubber insert is a harmonic damper. It does not perform a balancing function. It's idea is to remove unwanted harmonics caused by loads on the crank. The harmonics can lead to stress-related (resonance) failures.

Balance is the physical balancing of the rotational assembly: material is added or removed (normally in the crank counterweights) to ensure that the entire pulley/crank/flywheel/clutch assembly will not unduly shake itself to pieces within the designed operating RPM range of the engine.

Harmonics are related to the crank and block design, and operating range of the engine.
Balance is down to manufacturing tolerances: an econobox will have a higher degree of physical imbalance because it's cheaper to achieve, and a lower RPM range, which is safer for an engine with lower tolerances and cheaper to produce.

It's unlikely that the Ferrari engine will exhibit significant harmonics because the materials used are above average, the block is strong, and particular attention is paid to the crank to block mounting system to ensure rigidity of the rotating assembly.

The two concepts come together when talking about a crank pulley/harmonic damper, because a perfectly balanced engine can be upset by changing the end pulley to one of a different design: I personally wouldn't do it on a high-RPM engine without re-balancing the entire bottom end rotating assembly to take into account the new pulley design and characteristics.

Hopefully that makes sense.

 

Yes that is why I stated that the f131 engine is internal balanced. Where parts like a balancer or flywheel don't play a roll in the balance of the engine.

 

It applies to both. The rotating mass is balanced as a complete assembly. In both types there is scope to affect the balance by changing pulley type.

 

I worked on an MAK marine diesel which had a 12 inch diameter damper bolted to each camshaft and an approx 4 feet diameter one fitted to the end of the crankshaft- real fun to change one.

 

This has been a discussion for years on Rennlist for 997 GT cars with single mass LWFW's. Cam actuator bolts backing out and going down into the oil pump was a heavily discussed issue that many people blamed on engine harmonics. Dundon sells a dampener from ATI and I run it on my 997.2 RS. Does it do anything? I'm not sure. But I drank the cool aid lol.

 

If dundon sells them it must be some good cool aid. If I ever get a RS you dam we be sure it will get there full package

 

For me it's just a simple issue of I really don't think the juice is worth the squeeze. There's certainly many 360's out there that have well over 50K miles on them that are still running smooth and strong.
Just my .02 but I'm not seeing a realized advantage. As per my previous posts; My first hand knowledge proved to me that even GM got a huge cast iron 500ci. engine to run for a good long time without any balancer installed on the assembly line.

Kinda reminds me of folks that install a "chip" into their vehicle that claims a 5% HP increase. I seriously doubt you will feel anything from that upgrade in the driver's seat.

 

I have the full D4 package on it. It's madness.
