Is this bad?

[Betlog]

So i just got the WRX this Monday. My buddy was excited for me and wanted to see the car. Of course, he wanted me to switch it on and rev . Caving in, I turned it on and revved the engine up to 3,500 - 3,800 RPM on NEUTRAL. Given the car is brand new (I have about 250 miles on it) and not fully broken in, was it bad that I did that?

Nah. Don't go out and redline it, but a few revs aren't going to hurt it.

Revs aren't going to hurt it...but I'd definitely refrain from doing that if the car hasn't been warmed up at all...you gotta give the engine 20-30secs to at least cycle the oil around a bit.

One thing to add - the car was was driven prior to but sat for about 2 hours before I did the cold engine rev. That is, I drove the car, parked it, sat for about 2 hours (about 50 degrees ambient/outside temperature), went back to the car with my buddy, started the car then revved to 3,800 RPM.

You are fine. I wouldn't do high revs from a cold start anymore though. Like Mikie suggested, give it at least 30 seconds to get the oil cycling through and then you should be fine (I give it a little longer in the extreme cold). On break in, they recommend staying under 4K RPMs, so it sounds like you are doing that.

This is a good rule to follow even once you have the car broken in. I never just jump in and go, especially in cold weather. And you certainly want to make sure the car is at normal operating temps before you start romping on it.

i let my bugeye warm up for like 5 mins in the morning then drive it nicely till normal temp lol.

Yep I usually let mine warm up at least 5 minutes...Sometimes 10 minutes in extreme cold (I regularly gets in the single digits up in Maine). Not great for gas mileage, but I figure it is better for the engine. Also, shifting is rough if it is not properly warmed up in the cold!

A little bit off the gas mileage is well worth saving a bit of wear to the engine and drivetrain.

[Mikie13]

I let my car run for 30 seconds or so...then go. Keep RPMs low and slow until up to temp though. I have a 2 minute commute to work.

[RayfieldsWRX]

Yeah, depending upon situation, I either idle my car for a very few minutes, or not at all. Nice and easy through the neighborhood (shift at 2000-2500rpms, first 5 minutes or so). By then, my temp gauge is usually giving me the okay. Then I drive like my normal, wild, becauseracecar self.

[Sheleileigh Law]

Yes, I always warm up the car in cold weather - and it's been in the teens and single digits here - you should do that with any car really ...

[zax]

My best guess is it's completely broken. Borked. D.O.A.

I really doubt it affects it enough to even measure it. I had a night where I had to sleep in my car in well below freezing temps and had to run the engine through the night to keep warm. Only had about a quarter tank so I was worried about it and got up a couple time in the night to check... after idling for probably 6 hrs through the night the needle on the gas gauge didn't even move one bit.

I wouldn't necessarily go by the needle. Mine tends to update when it feels like it. I can be at a gas station(with the power on but not the motor) and it wont update until I actually turn the car on. I think there's some logic in the ecu that waits for xx miles traveled before it updates/rechecks.
