Why is there not a red line on this tach on my 2006 6.0 Powerstroke.? How fast can these engines safely turn ? Thanks
Great question! I found myself sitting in the ferry lineup the other day wondering the same thing. My dads 01 7.3 has a red line which is clearly marked fairly low, my 07 tach looks like that in a gasser.
My '99 V10 doesn't have the red line marked either, which I thought was weird. But with an automatic I doubt it really matters since it won't let you rev it high enough to cause any damage. My old VW was a diesel, and there was no tach, but you couldn't go beyond a certain RPM anyway since it was mechanically governed by the injector pump. Actually, you were more likely to damage that engine by lugging it than by over revving it.
