Heres one I have been pondering for awhile now. What is the function of this??? It is on the rear of the Ferrari FXX.

Looks like an air jack hose socket.
They plug the hose on there and the inbuilt jacks extend from the floor

Don't the jacks add weight (the tubing, pneumatic tubes, complexity, stuff like that)?
It would seem easier just to use regular jacks.
Enthusiast
May add weight, but many less mechanics needed and on a car that is not racing weight isn't a huge issue.

Nope. Different thing entirely I believe. Harmonic Balancer I was wondering if anyone could give me more information on a hamonic balancer, aka crank pulley damper, torsional damper, vibration damper.Originally Posted by Matra et Alpine

The phrase "harmonic" is to identify it as one specifially designed to match ( out of phase ) hte vibration in another shaft in the engine

Second > getting jacks under a car that low = PITA (ask Quiggs)
and possibly jack points are hard to reach.

I concur..cross plane and flat plane V8 are 90 degrees and rarely have balancer shafts. It is more likely that these balacers are linked to auxilary related imbalance or noise.

ah, got you.
That's a dampener, not a "balancer".
Mixed engineering terminology
A balancer is about introducing forces in opposition to the main object to reduce movement.
A dampener is about absorbing some of the forces to reduce movement.
yeah as described ... a mass with an absorbing material connecting to the piece. So the mass provides a "stable" platform for an absorbing element to limit the vibration. Usually a metalastic material.

Famously used on many an american V8...
basically as the wikipedia article states it is used to absorb vibrations caused by the torque impulses as each piston fires to make sure that even when they happen at the resonant frequency of the crankshaft they don't "resonate" and causes increased stress that will damage the crankshaft.
They are normally used on low revving american V8s that were used for racing because the increased RPM they operated at (when racing) happened to mean that the torque impulses regularly happened at the crankshaft's resonant frequency.
Also as noted many racers decided that they didn't need them... although I remember hearing about how someone used to do some math and mark a red area on his tach.... to remind him to not keep the engine spinning in that rpm range.
Power, whether measured as HP, PS, or KW is what accelerates cars and gets it up to top speed. Power also determines how far you take a wall when you hit it
Engine torque is an illusion.

Another quick question-
What are steam pipes for in big cities?

Where do you put the jack when the bottom of the car is flat and made of crushable material?

Suspension bits?Where do you put the jack when the bottom of the car is flat and made of crushable material?
I get your point though.

"Suspension bits" would be tough because the suspension would have to lift through most of it's travel before starting to lift the car. Plus, it's not easy to throw a jack under the car and lift quickly when you are trying to lift by the control arm or something.Suspension bits?
I get your point though.

Buy a lift.
