Spoon Engine Torque damper - Page 3

By adding the ETD and mounting it to the crank pulley side of the engine with the other end mounted to the chassis, wouldn't one be adding (an uncommon to OEM) torsional stress to the engine/trans mounts? I don't believe that all of the forward and aft energy goes into the ETD shock. I believe that some of this energy is deflected and shows up as torsional stress on the engine and trans mounts. Engine mounts are designed to stretch and compress and to accommodate some torsional stress. However, I believe that we'll see higher engine/trans mount failure with the ETD. Although the shortening of the service life of them won't be significant. In addition, they are pretty easy to r/r.

If you are worried about your engine mounts you might want to add Claymore's homemade ETD into the equation. I think your enigine mounts will be more happy with an ETD on the crank and flywheel side of the engine v. just on one side.

I've had ETDs on other cars and like Leonine and others (above) believe they offer real performance benefits to cars (i.e. wheel hop, smoother shifting, etc.). In addition, auto manufacturers use them on their OEM applications too. Why didn't our Fits get them - probably cost savings.

FYI Below is a pretty good write up on Club EL re: the pros and cons of the ETD.

Tagged for interest in this.

Wallet ready(as long as it fits with a Cusco front strut tower bar).

Claymore, I like your entire post and would like to add a thought to the above quoted part. First off let me say that I don't suggest this thought unless you're seriously stripping the car for race purposes. Nor do I claim that ALL race cars do this! We could use solid engine mounts to eliminate any engine movement thus eliminating the need for ETD's.

Can someone please direct me to a picture of the engine that is using 2 ETD's. Thanks!

Oh and one more comment...

dj_buddahi - just dont see this item practicle on a car that cant get 100whp without extensive mods, this part would makes sense if replacement mounts came with it and you had an engine that needed it

a 1.5 liter engine does not need this part just yet , i would rather get more under suspension pieces.

dj - though your opinion is well taken (and I'm not picking on you) I'm sure there are many Fit owners who would claim that more under suspension pieces would not be practicle since the car does not need it. In conclusion... no car needs any modifications of any kind. It's how the owner of the car preceives the things he/she wants in, on, and/or out of the car.

Hmm... I'll hold back my comments on this. However, maybe Claymore will respond.

will that damper protect me from the dreaded tank slapper?

Quoting from a different thread re: TQ Damper: Dickson wrote that according to Ichishima the first batch of AJR exclusive TQ Dampers "should be ready in March." Dickson also mentioned that AJR "will for sure host a groupbuy on these once they are available."

Dickson or Ben can you tell us what the status is on the first batch?

The prototypes that we have been testing, one of the braket broke off so we have spent a few weeks time just to develop a new one. All the information has been sent back to Spoon so they are manufacturing them now.

I hope to see them by the end of May.

"The world tends to unfold as it should...." "Innovative Mounts" stock replacements is probably going to be the only way to go!

Took the words right out of my mouth. But it sure looks purdy.

Hi all,

The final prototype has been done because for the past prototypes, we got problems with the bracket which kept breaking. It's finalized and they are in production now.

Here are some update pics :

-We have tested it with Spoon and J's Racing Strut bars and there are not fitment issue with the E.T.D.

-Another view

Thanks
Ben

Ben,

Please PM Price. I'll be your guinea pig because I have confidence in AJR and Spoon to manufacture this bracket so that it doesn't break.

Hi Lance,

I will let you know when they become available.

We are trying to speed up the process but we are having some issues with the bracket being not strong enough. We are working on it and will come up something pretty soon.

hehehe maybe its time to bring out those reinforced titanium brackets hahaha

Sounds like you need a Mechanical Engineer

I might be able to make some rough calculations and run some simulations, I just need some more pictures of the bracket, where it is breaking, what type of material is being used, what type of screw is being used including material, and approximately how much force the damper is exerting on the bracket. If you can't approximate that, I just need to know the specs of the damper and the approximate travel of the engine when torque is applied, I can do the proper calcs from there.

with that?
can you help me with my Vector Statics Homework???
