Does the M103 Engine Have A Rev Limiter? I was playing around today and went into the red on the tach. 1st time ever on my car. i want to make sure it has some sort of protection since it has over 220k miles on it. (i'm picturing the timing chain breaking)

It should have a rev limiter. Maybe some of the engine experts will see this thread. As far as I know, the M103 was made for revving at the redline all day. Great engine!

 

BUMP

anyone know what it's set at?

 

the limiter on my '91 is at 6600, but its redlined at 6200. I made the car hit the limiter in first gear while leaving it in drive so you should be able to do the same.

 

I was "racing" once in my 300e and decided to manually shift the automatic . I made a mistake and forgot to shift out of the "2". Lets just say I got to about 80mph and that sucker redlined in 3rd gear and the car jerked hard. I doubt there was a rev limiter in it.
