another thing i just thought of if you're feeling a vibration . . i can always feel an instant vibration the moment the fans kick on. it's very brief and once they get up to speed i don't feel it anymore but if you're right on the coolant temp where they're kicking on/off  i would think you could feel that. .. which could explain the "shudder" but not the ping sound.

timing chain also came to mind for me. . have a mechanics stethoscope?

Yea... I listened to each cylinder by the plugs. They all sound the same... I also listened to the oil pan to see if I could get any feedback... couldn't find it there...

The hesitation is not fan related. And once the car is warmed up, the hesitation goes away. At around that rpm is also when my exhaust is the deepest...which doesn't help because that alone vibrates the car..

I will check around the timing chain tomorrow...

Positive that the exhaust isn't hitting anything or itself where the two pipes run side by side?

What you're describing with the vibration could also be a motor mount.  You just ran it at the track.  Maybe it hurt a motor mount.  I believe the rear one is fluid filled.  Maybe it's no longer filled?  Just throwing out some ideas.

Do you still have your stock downpipes?  Try swapping out the SWs.

Also monitor transmission PIDs, see if it might be the torque converter.  That rpm range is a bit wide, but could be a lockup issue.  Note what trans temp is at the time the stutter/shudder goes away.  See if the issue occurs at cruise in that rpm range also.

Hmmmm... so auto transmissions are a magical beast to me. I have been noticing when I put the car in reverse after is been sitting there is pronounced click.

And also I noticed on the way back from the track when it up shift after letting off the gas it was a bit harsh disengaging the gear.

Daily driving the transmission regularly goes up to 200F.. but being as it's a non pp without the cooler and there hasn't been much in the way any other symptoms until now I haven't given it much thought...

Gonna do some testing today.. sounds like it could be the torque converter or possibly a motor mount like previously mentioned...

I apologize for not having a technical description of my previous torque converter issue, but the shop that fixed mine said diagnostics showed mine was locking and unlocking while being given no command to do so, according to their scan tool. 

I had major RPM fluctuations while driving though and no tapping/pinging. 

Hope it turns out to be a minor fix!

I have the reverse click after sitting. Only happens if I'm parked on level ground. Any kind of hill and it's not present.
You engine video does sound a little "buzzy" compared to most.
I have almost the same mileage on my 10.
I'll try to get a video.

Did you take the styrofoamy muffin off the fuel pumpy thing on the head ?  mine sounds ALOT like that with it off ...

Had a buddy check it out... he says he can't hear anything out of the ordinary but that the engine was a bit noisy however nothing he would find an issue. He asked if it was missing or having any other symptoms which i explained the vibration at 2300 - 2500 RPMs. He mentioned that almost every car has a slight vibration around those RPMS and sure enough my 1.5L ecoboost has a similar vibration although not as pronounced. It's also over half the displacement smaller...

Final verdict he said is that I know my engine best, if I am hearing something that he can't hear then it could be something in the extremely early phase of going out, but that a lot of these motors have different noises. If the car is running well, no loss of power, no other real symptoms besides this noise I am hearing that even if I took it to Ford they aren't going to touch it. Best bet is just keep an ear out and see if the noise gets worse or not.

He seemed to think it isn't worth putting much more effort into... his opinion is that it sounds just like every other ecoboost he has worked on...

He is an ASE Master Mechanic that worked for Ford for a long time. Now builds small and big block Race motors for people in his barn. We've been friends since I was in middle school, I tend to trust him.

I did ask him about the possibility of the torque converter going out... he did a few tests on it and said it felt fine. He reminded me that if I am tracking it, that once those transmission temps get to 209ish they can start to act sluggish and engage/disengage different than normal... that I need to let it cool down before getting on it...

So for now, I am going to table this unless something else pops up...

Now to wait for Julio to respond about why my meth pump keeps requirement me to up the voltage to keep pressure...

uploading a video of mine,  50k miles .. sounds really similar if you take off the muffin cover. be back in about 10 minutes'

I did and agree about the sound.

Pretty much what my mechanic said..

So that you know...that is the high pressure fuel pump.  It's a mechanical pump driven off of the camshaft that bumps pressure to over 1,000 psi.  Mine sounds exactly the same.

I have a Lincoln, so I can't hear the pump with the cover removed if the hood is closed.    My extra 200+ lbs are mostly in insulation I suspect.  Hood is composite, but NOT light either.

Yup, 100% familiar with it! I have replaced mine in the past during a fueling issue. I am familiar with that, the noise I am hearing is coming from behind bank 1 towards the middle of the engine. My mechanic said he didn't hear anything outside of the ordinary.

At this point unless there is something that happens, I don't think I have an issue... yet...

Sorry, I should have quoted Topher.  I know you're a pro with the fuel system in these cars.  Probably one of a handful of people who have replaced the high pressure pump themselves.

Out of curiosity, when was your last oil change and what weight are you running?  I seem to notice more valvetrain noise as my oil gets older.  Granted, my lab results also showed my oil at 6,000 miles was pretty well shot.

Far from a pro! I think Poleski at this point knows more about this car fuel system than anyone.

Oil was change about 400 miles ago.. I noticed the perceived noise before changing the oil... one of the reason I changed it at only 1800 miles. The other was I hadn't changed it since tuning for meth which can be hard on the oil.

I noticed this also. I took a video with it both on and off and there was a noticeable difference.

Need to upload to YouTube still...
