The calibrations on a track pack car are different. 5w50 oil use is part of the doc fence.

Lol, I was up with insomnia when I posted that.Grant 302 said:Doc fence?
Grant 302 said:And that does explain why TracKey idle changes as the car gets warmer. What I don't see is how phaser operation would be different in track use between TP car running 5W-50 and and 5.0 running 5W-20. I should probably ask them if anything like that is changed on my FR Procal tune.
BigTaco said:Grant, I would think that on track/high load would be where the differences between 5W-20 and 5W-50 would be the greatest. One is thicker than the other once they are hot.
The Boss track key owner instructions specifically call out 5W-50 but the current track cal instructions for non Boss S197s does not.

Call Ford Performance and ask them about running thicker oil when you track the car.Mxkon said:So now I am left with this technical struggle. Is it "better" for the engine to stay with the thinner less protective 5w20 oil on the track, or gain the added protection of the thicker 5w50 and hope the thicker oil doesn't do any damage to the cam-phasing system?
Honest question, how bad could it be?

For anyone reading this later on and having similar concerns or questions about occasionally or beginning to track a Mustang GT (non track pack)
I have talked to guy at Ford Performance and he has assured me that 5W50 is the oil that the 5.0 Coyote engine needs under track conditions (high RPM & temp). and the oil I should be running at the track. However, because thicker oil will impact the cam-phasing system, it is recommended that I use the suggested 5W20 when im not at the track.
With this knowledge and per my original concerns about vehicle temperatures climbing up past an acceptable safe range I am doing the following:
1) Upgrade oil to 5W50 for all track use (HPDEs for the foreseeable future)
2) Install oil temperature sensor & gauge to help accurately monitor temps based on my track use.
3) Install upgraded radiator to optimize existing coolant system.
4) Install transmission cooling scoop to help keep transmission a bit cooler.
5) If oil temps are climbing to high at my next event climb out of a safe range -> Install oil cooler (Setrab 172 seems like a good choice).
This should solve my issues/concerns at least until I build the car up into more of a track toy and a LOT less of a mixed use vehicle.
Thanks everybody,

Sounds like a good starting plan to manage temps on your Mustang during Track days. I didn't search this thread, but I assume you already have the front brake cooling hose kit and Dot 4 fluid installed.
When do you plan to run your next Track session? Keep us posted.
Thanks,

UPDATE:
Yes if you have any aptitude or previous experience with track driving(HPDEs in my case) a 5.0 Coyote motor going over 6,000 RPMs NEEDS an oil cooler to stay under 260F.
using every bit of 7,600RPM when i could
"Safe" is clearly an operative word here and anything over factory specs is imparting stresses on some component of the engine that Ford engineers decided should be limited to 6,700. However, after reading up on the subject for hours and hours there seem to be a lot of 5.0 Coyote motors being used in road course and especially drag racing that have been tuned to see 7,800, or 8,000 and most seem to be holding up well. I make this assertion of "most" based on the handful of people I have spoken with at HPDEs running much better prepared mustangs than mine, as well as the seemingly few forum threads about NA engines blown at high RPMs (few compaired to the # of threads about how engines fail after 5k miles of having a supercharger w/o any supporting engine mods).Sorry to go off topic but I've been wondering about this exact thing. You have a GT and the factory redline is 6700. What is a safe RPM To rev these things to. Are you modded to run that high?
