R50/53 Is it ok to redline?
Redlined mine mine when I was taking off out of the Tollbooth this morning. I know I should get an IPASS but it's just so much fun to stop and pay and then catch right back up to the cars you were cruising next to, it's like my morning pit stop to work...
perhaps not?
I've owned an o4 MCS and recently got an o5 MCS with Dinan stage 5 upgrades. Perhaps that is incidental.
On both cars - on occasion, when I have red lined the car , it has gone into limp mode, SRS light comes on and I need to stop and restart the car to being it back to life. The SRS light goes off in a day or 2. However, the whole experience makes me feel like I did a BAD thing.
Anyone know what happened?

I have actually heard that regular (about monthly) redlining is benificial and should be done on purpose.
Something about piston throw being a fraction shorter when not being pushed real hard and a ring of carbon deposit builds up. When you redline it gets the piston to "stretch" that little fraction and knocks that ring off before it builds up. This would be important because if a substantial ring built up and you had to redline or accidentally down shift, when the piston hits this ring major damage could happen.
I actually don't really care if this is true or accurate. My possible ignorance gives me a great excuse when the wife is with me.
"Babe I am just doing regular cleaning ..."

Let's put it this way ... Your engine RPMs are stored and can be read at the dealership. When you hit the rev limiter, the revs CAN go past the limit for a brief period of time ... hence OVER-REV
On an uneventful ride one day ... Your engine goes quickly to redline on a missed shift, or a 4th to 3nd/ 5th to 2nd ? miss shift ... or upon quick acceleration
Your new car's engine blows and you take it in to the dealer ... Is it covered under warranty ?
NO, if they don't want to, they have the proof to deny the claim
On that note, I have a shift light installed ... with a raised rev limiter on a modded Mini, making 230 hp at the wheels
I am trying to stay safe, to a degree, and yes power does climb all the way to the raised rev limiter
Long live the MINI !!!

I would say that red line is there for a a reason guys.
What Jso123 refers to above is what some years ago was referred to as an "Italian Tune up". A necessary evil for older rarely driven foreign cars by shifting at high revs/speed to blow out any carbon buildup. The end result was huge plooms of black smoke out the tail pipes and often a smoother running engine.
Today we run way better fuel /oil all of which have detergents and additives to prevent this purported build up. And with regular maintenance and oil changes at 5K miles, I fail to see how this is necessary today and doing such on a regular would most likely result in premature engine failure or damage.
Besides, these toll areas are not our version of the Kentucky Derby, and are clearly posted at 15 mph. On many occasions I have seen toll takers walking about from booth to booth at shift break and would highly discourage this behavior and any futher postings of this nature here in the future - In accordance with NAM Regs.
Always - Motor Safe.

... huh........
fwiw 2005 MCS redline just over 7000rpm @136mph I've done it and have not damaged my motor.
in accordance with the NAM regime I am obliged to report the above was done on a closed course.
oh and also, despite the uneducated views of some above who like to spout their ignorance as fact there is not a single negative effect of bouncing off your rev limiter from time to time.
I for one have never seen a toll operator walking around past the booths where any redlining would occur either.

No one is saying that it will destroy your engine and its components if you do it time to time, but who would actually argue that its "good" for any engine? How could more stress and higher revs be good? Is it fun? Is it the reason we buy sports cars? Sure!! Thats why I did. Is it going to help my engine last longer? Hmmm.. Thats tough.
