Engine torque damper ?

No, it's actually not. It started way before that. They're very common on muscle cars. I never ran one in my GTO but plenty of people did. And Camaros, Mustangs, etc. It's far more common on high horsepower V engines than in imports I'd gather given everyone's lack of familiarity around here.

The idea is, you are preventing the energy generated by the engine from being wasted twisting the engine on its mounts rather than twisting the transmission/driveshaft. It's a tiny gain in efficiency of the drivetrain. Also, it helps to increase the longevity of the engine mounts as the forces they're subjected to are correspondingly reduced.

I don't get whats the fucking hate here. I think camber hellaflush the fuck out of everything, I was asking why they don't exist for our cars and if they would have an usage or not. I didn't talk about adding stickers bomb to my car or plastidipping it, Jesus people need to chill the fuck out sometimes. Thanks to those who actually provided answer, and that' s even aimed at you, @jsimon7777 even if your shit was full of sarcasm.

My friend I completely agree with you I have cusco engine mounts Perrin trans mount whiteline diff mounts and there is still a shit load of engine movements the first company that makes a engine damper for this car I will buy it I don't know what's wrong with ppl when you actually asked them a very good question they start being smart like they know everything.

But what negative effects are you seeing from the engine moving slightly?

The torque damper for fwd makes sense because it reduces wheel hop. Engine movement has nothing to do with wheel hop on a rwd. Diff movement does. So maybe a diff torque damper would be what you need.

Not hating just explaining.

Ya, this. It was common for high HP engines to demolish motor mounts. If you want to be old school about it use a chunk oh chain.

Just thanking the people who vindicated your original question would have been full of win. This, not so much.

Feel and responds with solid engine mounts the engine feels like it's welded to the frame... Yeah there is a lot of vibration but I don't mind it coming form a EK with B18C5 with Hassport mounts and a S2000 with evasive mounts maybe that will explain!

[Tromatic]

So half the people here are talking about reducing the transfer of engine torque to the frame/chasis of the car, and the other half are talking about increasing transfer of engine torque to the frame/chasis? I will be selling a torque-equalizer soon for the FR-S. It does everything.

I'll take 2 please.

You got everything perfect except I have an issue with this one statement.
Boxers are "Internally balanced" in that the layout of the engine is inherently opposed so like forces cancel

When a cyl hits TDC on one side, another hits TDC on the other side so a lot of the forces that contribute to vibration cancel.
In a straight or V configuration, they do not totally cancel.

The Torque damper cancels net torque on the motor due to the acceleration of the rotating mass (crank, rods, pistons, FW, CLutch, Accessories, drivetrain etc).

This will apply a torque to ANY engine that has a single output shaft.
So yes, we COULD use torque dampers on our engines AND our diffs if anyone made them.

Anyone who has seen the twisted chassis of most 70s ford pickups can imagine the torque that the engine applies to the chassis every time you step on it.

I think our engines are just low enough output (stock) to not need any damp(en)ing except the motor mounts.

So following that though, a stronger differential mount/damper would be more useful

I'm a bit late to this thread, but feel it could use some reinforcing:

This^^^ I'd be in for both engine and diff dampers. My FR-S has a very clear delay between engine ac/decelerating, and the wheels ac/decelerating; I can literally feel everything winding up before the car responds. Working on getting/installing stiffer bushings when/where available...

I discovered this, which is exactly what you were asking about. I cant seem to find how it installs though, i imagine it connects the engine to the top of the strut tower based on the image of the parts. This would dampen the side to side movement that these engines encounter when revs are applied heavily.

God
There's soo much torque. How can I dampen it?

Sorry, couldn't help myself.
