Flooring it while engine is cold

anyone ever had to floor it with the engine only having about 45 seconds of run time? I had some guy come flying around a corner I turned onto and had to floor it and I’ve never heard the 3rd gens be so loud before as it was this morning. Just curious. Any thoughts on possible engine damage or wear?

 

I doubt you did any damage to the motor but its definitely not good for it. I try and take it easy on the throttle until the motor warms up.

 

Most of your engine wear (about 80%) occurs during the first few seconds of a cold engine start up. After that I'd say that in about 30 seconds all that needs oil pressure such as timing chain slack adjusters, or lifters on engines that have them would pretty much be pressurized and all that is required is a normal drive at moderate speeds, not high speeds for a few miles for the rest of the major vehicle components to equalize, and I'm talking shocks, p/s, A/T rear diff etc.

In your case, I wouldn't recommend you make a habit of it if you intend on keeping it for 300k, cause you just knocked a few miles (i kid) but no one really knows lol!

My take, don't looses sleep over it.
Odds are you'll never experience any adverse effects from this one instance, because if something were to happen directly related to your action, you'll know about it straight away.

Cheers!

 

Agreed. You're fine.

 

In all seriousness it’s fine, though it was probably due to change cold cat, I’ve noticed that on my m3, it’ll scream like banshee when cats are cold

 

My solution is to remove the rear cats entirely... Y PIPE HERE WE COME!

 

If it weren’t for emissions I would too

 

Good discussion on this though - I live in a neighborhood flanked by two very busy, 2 lane side-roads that have some blind curves and hills to contend with. These are also heavily traveled as side roads to access the cities main arteries... so I regularly have a similar issue as OP where I will pull out of my neighborhood only to see someone racing up and over a hill requiring me to accelerate much quicker than I'd like w/ a cold engine. Still never floor it, but not uncommon for me to have to race it up to 3k to keep from getting hit.

So the debate is - how long to idle vs. just drive it if there is the chance I'd need to go 50-70% throttle within a minute or 2?

 

I rarely do this, but have ripped to the fire house ~1.5miles away on very cold nights. When you get banged out for a working structure with unknown occupancy, I seem to get up and go pretty quick. I want to keep my truck a long time, but sometimes a few seconds may or may not count.

 

Did the same thing this morning. Accelerated hard onto the highway about a mile into my commute. Lagged for a second, hard drop, engine revving loud as hell. Only happens to me when it's cold. Parked outside last night and it was in the 40s this morning, which is cold for Phoenix.

 

Hey, a fellow leatherhead!

Our station bays are heated but when we catch a call, we jump in the trucks and run like banshees. NO vehicle is made to do that every time it goes out for 100K miles.

OP, you only did it once. You're good.

 

As our cops (blue canaries ) call us Hose Humpers - Were a volunteer / call dept so from our house to the station is when the engines run cold cold to ripping. Our chief's go direct, but our trucks are in a station kept around 52 to 55F. How come we never have fires from like 35F to 45F? Always fucking cold to god damn hot & humid - seriously...

 

Thanks to all you guys for replying and easing my mind! I was worried I might’ve done some serious damage but i just drive it home and it drive fine no issues or odd things noted.
