New WRX owner - a few questions
Hey guys, sorry if this post isnt in the right category but i have a few questions about some characteristics of my new car.
This is my first subaru and i am a fresh owner having purchased it about a week ago. It is a 2009 WRX 5 door hatch, and bone stock aside from the muffler delete i had done immediately.
The first thing that peaked my interest was the behaviour of the ABS system. I noticed that when the ABS kicks in with the clutch depressed or while in neutral, the engine automatically revs to around 2500-3000 rpm. Is this normal? This is my 4th vehicle and i have never heard of this before. I would assume this is to maintain high brake pressure for the intermittent behaviour of the ABS? Not sure, but although i wouldn't label it a problem, i am curious to learn why this happens.
The second thing i noticed is the cars performance during warmup. I live in Saskatchewan and the temperature here during the winter is anywhere from -15C to -40C. I always baby my car until the temperature has crept 1 or 2 notches onto the coolant gauge. What i've noticed is reduced power until the coolant temp reaches about the halfway mark. After this point, the car seems to have a massive power increase. I would imagine the computer either reduces boost until ideal operating temperatures, or possibly the exhaust/turbo temp is too low at this semi-warm state to spool the turbo efficiently. Again, is this a normal behaviour? My last car was a 2011 and also turbo'd, and there was no difference in power from barely on the coolant gauge to full operating temp.
Thanks in advance for any opinions!
