Cold start: N vs Normal
- Thread starter Timola
- Start date
As the Start default for unmodified N-cars (in the USA anyway) is Normal, the question is N/A, however the flap is observed to be full open on start and closes when the start cycle is complete.
I was told when I bought my car from new not to run N mode until the engine is properly warmed up, so have stuck to that rule.
Any N mode is fine after a cold start - just wait for oil (160+F) & water(190+F) to reach normal operatiing range before pushing it.
Yeah I probably should have been clearer - gradual rev rise as temps rise rather than up to 5k from cold cold...
Context: I've an uphill junction onto a dual carriageway that is normally a standing start or at best 10mph, it's about 5 mins down the road, so the elec rev warnings lights are still orange but are going out (temp dial about 1/4 of normal). I tend to short shift it in 2nd at 4kish but let it run in third to 5k rpm to get up to speed. (habit that formed in my previous mustang as if I went too hard in 2nd due to the camber change from the junction to the road it'd fishtail in the dry)
Keeping it as low as you can if possible - let the rev guide (rpm color bar) stay ahead of the tach.
No isn't safe, in general all car or better engine enthusiasts talk about going max to around 3000 rpm's, so this is the common rpm.
Also important not to do quick attempts on the throttle to reach that 3000, simply drive gently to 3000 for a while till oil is in operating temperature.
Always think of these modern engines are fully alloy, be gentle!
I personally think there's far too much historic/legacy info used when referring to "safe" margins with oil protection - I mean if a quick blast to below the "orange" light limiter on a slightly cold engine was going to be causing catastrophic wear then there's no way that Hyundai would offer a 5 year unlimited trackday warranty - you're going to put significantly more wear on the engine on track than you ever will from a slightly cold 10s run up the rev range.
I have always just gone with "be sympathetic" - I'm not great when I've first woken up / just starting to exercise, and neither is a machine, so give it a few mins to loosen up.
