Talking Lightwieght Flywheel in production by SPEC

So this is what we’re doing…we will be making a flywheel that interchanges with the stock type pressure plate AND a separate flywheel that accommodates a unit similar to the one we use in the RS. The factory pressure plate design cannot be built as stout, so the big power people will have their option and everyone else can have theirs. We will likely produce the flywheel in both steel and aluminum, but expect the aluminum to be the choice on the ST cars, since they’re fwd.


[He continues and explains what he is talking about]

The stock pressure plate is not good enough for any real boost mods. Our pressure plate is so good it is worth getting the required flywheel. We will be making a flywheel to accommodate the stock type pressure plate just for those that do not need any more.

I just got back in town today and everything is in process. The ring gear was not one we use, but we actually already have a sample from the gear hobber that should be in Wednesday. Once confirmed, we can get your flywheel back in the mail and the material ordered to make the run. So yes, [next] Monday if the gear arrives like it is supposed to, and then it is all about sneaking them into the assembly schedule. I am pushing this through as quickly as possible..I want to see these units fly outa here asap. We are normally 4 weeks getting new units prototyped, but I am getting this one through in a fraction of that. If the ring gear had been on the shelf, we could have ordered material and put it on the schedule today.

This is a build log of sorts that will lead up to my reinstall of the flywheel and pressure plate assembly later next week. A video will be uploaded shortly showing the removal using inadequate tools leading up to using tools that have more "umph" so-to-speak.


USE CAUTION WHEN WORKING ON AN ELEVATED VEHICLE. CHOCK THE WHEELS, USE EXTRA JACK STANDS, USE AN ENGINE SUPPORT BAR, USE A FLOOR JACK AND 2X4 FOR EXTRA SUPPORT ON THE ENGINE, WEAR YOU EYE AND EAR PROTECTION, USE STURDY LEATHER GLOVES, WEAR LONG PANTS AND AT LEAST LEATHER BOOTS BUT STEEL TOE IS SAFER. FAILURE TO WORK SAFE MAY RESULT IN PROPERTY DAMAGE, SERIOUS BODILY INJURY, OR A VERY GROSS DEATH. NEVER WORK UNDER AN SUSPENDED LOAD ALONE, TRY TO HAVE ANOTHER PERSON WITH YOU. PLEASE FOLLOW ALL SAFETY PROCEDURES WHEN USING AIR TOOLS TO PREVENT DAMAGE TO YOU OR YOUR VEHICLE. IF YOU DONT HAVE THE RIGHT TOOL, STOP AND BUY/RENT/BORROW THE RIGHT ONE.



I didnt want to say anything about this until i had the flywheel off and ready to ship but, Spec has agreed to use my flywheel assembly to make a new production lightweight billet for the Focus ST!

If everything looks like it should, we can order material to produce the new flywheels as early as Tues. We are looking to produce this unit as quickly as possible, so we will not be dragging our feet.
The billet flywheels in a dual mass application like the ST normally produce 10-18 hp gains, in addition to rate of rev gains.

Below is a video of the removal with some commentary from me and ocysP(mostly talking about specs and the manual we used to do this)

[video=youtube;upufY5KUbps]http://www.youtube.com/watch?v=upufY5KUbps&feature=youtu.be[/video]

Here as some images of the pressure plate and flywheel assembly. All of the work leading up to this was completed using ocysP's how-to on installing an LSD. This will eventually be completed to show the how to remove/install the clutch and flywheel assembly as there is not one up yet

Not likely given the fact that the NA uses an mtx75 and the ST uses an MMT6 gearbox. One was developed by Ford specifically, the other is built as a joint venture with Getrag and Ford.

It appears that the 2.0 Duratec and the 2.0 Ecoboost have the same flywheel. according to my source there is no mention of a non DMF application for the 2.0 Duratec. with that said images show two different flywheel face designs.




EDIT:

The flywheels are the same. Part numbers for both the 2.0 Duratech and 2.0 Ecoboost match. Source: Ford Helm shop manual.

I still say pull yours to find out if they match. It wouldnt be the first time a drawing and part number have been wrong

Thanks for sharing the info with us over here at FF and welcome to the team. It is quite annoying having the DMF on the NA as it doesn't have the torque of the ST. I am not sure if you have ever drove one however it's hell to do a first gear pull. Are you a Rep for SPEC?

I hope you don't mind, I quoted your original post as well as a link over to the NA side of things so see if anyone in our neck of the woods has any thoughts on the subject.

No im not a Rep, although I am getting their first one for free in exchange for letting them use my flywheel. I have not driven a manual 2.0 Duratec.
