After a night at the casinos my friends egged me on a little to hit the gas, and I just did because they're visiting from out of town..
The engine had been sitting out in the cold for a few hours, and had 30-60 seconds before I got on it for them..
How bad is this for the engine? I took about a 20 minute drive home let the car warm up, cool down etc.. i NEVER even move the car until it's pretty warmed up, and I never floor the throttle/use the boost until the engine temp is at fully operating..

How badly have I hurt her?

 

I don't think it did any damage as long as you weren't on it too long. Its not something you do all the time so I don't think she's bruised up. Maybe hurt feelings but nothing too bad.

 

I probably hit 70 2 or 3 times.. like do it slow down to 40, hit it some more, slow down again..
ugh i really didn't want to do it but i didnt want to be a d-bag haha

 

You should of drove it till it warmed up then hit it. Was the casino far at all from where you guys were going?

 

well yea i know.. i NEVER hit it until its fully warmed up.. just this once
we were leaving the casino, and they were going home and i was going home, they wanted me to floor it before our exits came up..

hopefully no damage, i mean honestly there shouldn't have been unless you do it all the time right? like i said i drove it for like 20 after, let it warm up all the way, gave it some more boost and let it cool down all the way, and then turbotimed for a little and then off

 

You most likely did nothing ... Don't be too paniced about it. I mean if u did it from a frozen cold start to WOT, then fine but as long as the oil and water is atleast up to a moderate temperature and you didn't bang the living **** out of it it'll be fine. I see people do that all the time - some are just lucky and get away with it but in general, you really should just turn on the car fora few min while u say goodbye and everything and by the time u get going, your car is pretty much ready for it...

 

yea.. i'm hoping a one time run like that will be all right
temps weren't up at all really, but the motor had been runnin for at least 30 sec to a minute so hopefully that helped a little..
i mean really what am i doing by flooring it when it's cold?
less lubrication/protection from the oil because it's not up to temp?
i'm sure there's some wear, but what i was hopin was that the car just wouldn't run as quickly as it could because the oils not lubricating as best it can

 

Yeah, I agree with what the others said. Def don't want to make it something you do on a regular basis. I have friends egg me on and I give them a ride and shift at 2500 rpms and say,
"Yup, that is pretty much what she's got" Then when she's all warm and they are least expecting it I hit the studder box and scare the **** out of them

 

What gear(s) were you hitting those MPH's in? Engine speed(RPM) would be a more useful information than just plain MPH. How high did you rev the engine that first time you stomped on it cold?

 

The car should be fine, but not a good idea to do this all the time. my 2 cents.

 

oh... i mean, i shifted like i normally would if i was hitting it... a little under.. like 6.8, 7? But the car should be able to take the ONE time i've done that in it's entire life righ

 

Its not a old v8 from 1960 that will get cyl. wash down, its fine.

 

Omg ur going to blow up ur motor!!!!

If you have the stock Boost control solenoid and hit full throttle when its cold, it only hits like 10 PSI of boost.

 

The quickest way to accelerate engine wear is to run it hard when cold.

Engine coolant temperature reflects the temperatures of the internals. The internals are built such that the proper clearances are attained when the engine is at full operating temperature (which causes metal parts to expand to spec). Anything less has the tolerances running out of spec, which increases wear.

The oil requires more time than the coolant to come to full operating temperature, and until it does, it will not behave like its expected viscosity. This can create a starvation issue at high rpm, where oiling demand is high, and the oil cannot flow well enough to satisfy demand. Modern BMWs even have a moving redline on the tach that starts low when the oil temp is cold, and movers higher as the oil gets hot. The best policy is to not ask a lot of rpm or load from an engine until the oil is at least 170deg F (75 deg C).

To a high performance engine, an oil temp gauge is as valuable as a coolant temp gauge.
