Poll: What Temperature do you let your Oil warm to before going all out? - N54Tech.com

codesx

Curious what everyone's comfort zone / magic number is in this regard.

At what temperature do you consider your car appropriately warmed up and begin to target max boost and RPM?

Myself - Knowing that the JB4 doesn't provide over stock boost until the Oil is past 70c (158f), I personally have been letting this be my guide.
I drive her gentle until > 70c (158f) and then I allow myself to hold the skinny down.

Once JB4 is active, then I smash. 160F

I like the statistics! Glad I'm not alone!

Somewhere between 160-200f. Depends how patient I am.

I go off water temp. But oil temps are somewhere around 110ish at the coldest.

I go off water temp too. I get the water temps up to at least 190, then as long as oil temp is registering on the gauge I’m good.
You definitely want the oil warm, but engine operating temp (water temp) is more critical IMO. I guess you could look at it like this; water temps for engine, oil temps for turbos... as far as normal operating fits and clearances.

Almost full oil temp. Being in Chicago and construction zones everywhere, rarely do you see a chance to get on it

I wait till the gauge budges past 160F to get on heavier boost, but even then I don't rev too high until it gets a bit closer to normal. Depends on the outside temp as well.

Interesting perspective.

My water is always hotter as they both warm up, so rarely pay attention . (though it's on my choice list of phone gauges)
I'll watch my water in colder and warmer weather to better understand their trending. (I usually watch the water vs. oil just in hot weather)

My sympathies.

This is slightly off topic but part of,
Doesn't trans temp play a role here too?Say for auto.if your full throttle at 160f what about the trans temps,what's the safe number there for shifting,full load?

My trans temp stays right around 173F when up to temp. If I'm doing multiple gear pulls like drag racing/highway rolls I wait for my engine oil to get to around 190F or so, by that time my trans temp is at least 130F-140F. I notice the trans operates smoother when it gets warmer. Also keep in mind that you don't shift under full load, most people have autoshift boost reduction set to 60% or so as your transitioning from gear a to b, the trans is only under 60% load until you're fully into the next gear.
