information is hard to gather on this site

I have yet to determine if the old line will not interfere with the new mount. Vorshlag is a race car shop. I will buy the parts, exluding the PRESSURE TORQUE LIMITING/PTL POS line. Hopefully before the end of March I can get this sorted out with this home made TSB and the 28 inch intercooler, hard lines etc before Tejas heat sets it........let the games begin.


Photo #54, 55, 56 ..... custom fabricated mounted JLT OCC below -- I can have Vorshlag fabricate the same as you view here similar for the ST. Not rocket science.........

Hello all! Proud new owner of a 2k13 Peformance (Spirit) Blue ST2 reporting in!

After reading over the 13-6-10 RMM TSB, and the TSB mega thread, I'm still curious about the Clutch Line PTL (Peak Torque Limiter). Here's an excerpt of its operation from this blog



Since the first day I drove the car, I noticed that the pedal wouldn't fully engage if I'd lift VERY fast (boarder-line side-stepping). The engine would bang around, and I'd actually feel the pedal smack up against my foot after a short delay. I figured it was this valve preventing the flow of the hydraulic fluid, causing the dual mass flywheel and clutch to cycle between loading and unloading. The new TSB seems to resolve TWO issues: the weak motor mounts, and possibly an overly aggressive delay valve. I was wondering if anyone knows for a fact that the revised Clutch Line PTL (part number ending in 'B') lets MORE or LESS fluid through before it limits fluid flow.

I'm aware that the Honda S2000 scene has a similar issue, they call it a Clutch Delay Valve (CDV). It's great for daily driving, but not for spirited or track driving. Some S2k drivers go so far as to remove its functionality. I wonder how our cars would react to removing the PTL/CDV altogether (ignoring that warning in the description). It's a trade-off like everything else though...you'd be shocking the drivetrain more, but would have a MUCH more direct feel of the clutch.

great write up! DV6Z*7A512*B not for me...........

That article reads like pure corporate speak. Not worth the bits it took to transmit it.
 
I am resurrecting this thread, the information on removing the restrictors in the clutch line on page 3 should be a permanent DIY sticky. I only have 3200 miles on my '14, but up till today every time I tried a hard launch all I ended up with was the sickly smell of roasting clutch. Took 20 minutes to remove the line, tap out the restrictors with a 9/32" drill bit and hammer, then reinstall and bleed.

Immense improvement in clutch initial bite and 1st gear hard launch. Ford does some silly crap, but the new line was one of the worst I had seen. It saves wear on the tranny and potential warranty repairs, but then dumps it on the owner when the clutch hot-spots and slips. "Wear item" my arse.

Does this car not have a dual mass flywheel? I can't see why it wouldn't. That's the damper for shock to the drivetrain. I wouldn't worry about drive train shock.

Sure it has a dual mass flywheel, until someone goes and puts a single mass flywheel in to replace the dual mass one with a lighter unit.

The peak torque limiter is meant to slow the application rate of the clutch further to prevent damage to the transmission.
 
im wondering if this is why i have rpm flare when drag racing.

literately i shift at 6k and it goes to 7k- so annoying-
i first thought it was ffs in my tune - now i think maybe this tsb changed my line.
