Question on "when" 5.0 is "warmed up"

[gadgtfreek]

From a spirited driving perspective, especially on a car with any power and any mods, I tend to baby them when warming up after a cold start. I know generally ECT at 165 or higher is one, but since this is a large motor with a lot of oil, is something like cylinder head temp another data point to watch to know when you are ready to drive it a little more hard? It looks like normally, the cylinder head temp readout stops rising at around 200 degrees.

I am generally shifting between 2-3k on cold starts now, let it idle about 15-20 seconds before pulling out of the driveway. This is my first Mustang, so TIA.

Essentially just wait for the RPMs to revert back to a normal state after a cold start. You really don't have much to worry about with these newer cars vs the old. If you live in colder climates id let the car idle until it gets to operating temperature. Should only take about 30-60 seconds for that to happen.

These engines do get warm much quicker with the way oil flows through the block. Technically it's best to let the ECT get up to 165 before you go above 3 -3.5k rpm's. Viscosity and lubrication (friction reducing effect) change and become optimal with temperature. The metals within your engine also expand and become less prone to to damage/wear. One of the harshest scenarios your engine goes through is the cold start up. I usually let my car warm up for 2 minutes before I move it but I'm a dork

I wait like 5 mins after a cold start, so that makes me Harry Potter haha

Hahaha. Seems like the 165 is more universal than I thought. My previous Honda was tuned, had a turbo, so I def babied it until over 165 which was a common recommendation for that car.

If I just need to move the car in the driveway I go for a 20 minute drive...

I' do the same thing! I really thought I was alone with this guys lol

I have the regular gauge cluster, and I just use the Gauges menu for all the readouts. I've noticed that the Engine Oil Temp becomes "Normal" when the cylinder head temperature reaches 180. So I typically don't rip it until I reach that point.

i generally start mine and let it sit for a few mins before I drive it. I don't get on it much either until it gets to at least 180* CHT. I feel like this is especially important with a supercharged vehicle as generally you are running 5w50 or a similar heavy weight oil, so I make sure its warmed up a decent bit.

 

[Jordan @ Lethal]

Definitely. Lots of extra pressures inside a boosted car as well. Gotta make sure all the parts are warmed to spec to ensure they play nicely together

I do exactly this

I let it get to 190* CHT before revving over 2500, and let it get almost halfway into the green on oil temp before going WOT/redline.

Until oil temp is “normal”. I have a PP car so I usually check the oil psi and see if it’s to “warm” specs versus still running high, indicating the oil isn’t to full temp.

I don’t know about everyone else; but my GT feels a little stiff until it’s fully warmed up.

I guess we dont have anything other than oil pressure in ours? I haven't seen an oil temp. I think their may be one on the ngauge.

Have Launch Control enabled, once it is at operating temp the little LC will display on the dash.

It takes A LOT longer than 1 minute for engine to reach operating temperature, even if you're driving the car. But it's not needed to wait for that. Just like you said, until rpm fall into normal idle level, which take about 1 to 2 minutes on my Bullitt when cold.

It lights up MUCH sooner than it should man, at least on my Bullitt. I tried it, but it lighted up about 3 blocks from my house, so I knew I couldn't rely on that. After I installed the GT350 oil temp gauge (admittedly not very accurate), the 'LC' lighted up well before oil was at 150F, which I consider the minimum temp to rev the engine higher. So I turned it off. By the way, the oil temp gauge shows full operating temperature way too soon IMO, so probably not very accurate. And yes, I know the oil cooler is coolant-to-oil, but still, with 10 qts, it should take longer than my gauge says. It shows at operating temperature before a mile at low speeds. So I wait a few minutes after that, just to be safe.
