Okay, here's the situation:
In the mornings when pulling out of my street to go to work, I have to turn onto a busy 4 lane road. The road is curved and has a hill right before my street, so I can only see about 1/10 of a mile down the road for oncoming traffic. I make a right hand turn in the same direction as traffic. The speed limit is 30 mph since it's a residential area, but most people do 60+ (I live in the Chicago area where most drivers are anuses).
If people obeyed the speed limit, I wouldn't have a problem. But, what frequently happens is:
- I'll look down the street and wait for the coast to be clear
- I'll make my turn onto the 4 lane road
- Some butthole(s) will come flying around the corner at 65 mph and pretend like they are going to ram me. Some of the more extreme buttholes will even speed up.
Needless to say, it's very dangerous. Five teenagers were killed a couple years ago coming around the curve. Ricers always drive nuts through there too. I'm lucky I haven't been killed yet. I usually try to accelerate to match their speed by the time they reach me, or at least come close (which is very easy to do in the Cobra). This lessens the danger significantly.
So, the question is:
What is the maximum safe RPM I can turn without stressing the engine. Remember, the engine is cold and has only been running a few minutes.
In order to get movin', I have to get on the throttle a bit and step into the boost a little, but I try to keep it under 2500 rpms. Most of the time I can usually keep it under 2000 rpms and merge safely. Is this OK for our Cobra engines when they are cold?
I have a friend with an M5, and the redline on his tach will change depending on how hot the oil is. On a cold 25 degree Chicago winter day, his tach will show a redline of 4000 rpms at startup. It gradually gets higher as the engine warms. However, the M5 engine is very different and runs a heavier weight weight oil.
So, what do you think?
