the truck in my sig 99 F250. As I stated before its had 2 owners over the past 19 years not including me, it was never driven hard always easy all the time. I drive it easy also, its bone stock besides a cat and muffler delete I had done to the stock exhaust, sounds pretty good. Last week after I had the exhaust done, I asked my dad to rev it up in park so I could hear the exhaust from the back. I kinda freaked out as he hit redline and it bounced off the rev limiter twice before I yelled for him to stop. I'm pretty certain the engine has never hit the rev limiter not once since its new. The engine sounds fine, drives fine, but could that have shortened the life of the engine or caused any damage? I know the 7.3s are pretty tough, its never been chipped and is stock besides the exhaust, but I just want to be sure.

It hit the governor. Nothing wrong. Infact diesels are designed to run at the max governed speed all day long.

Exactly... these same engines (as the 444 variant) are used in BIG trucks (think F750) like power line companies use, and also in 50-60 passenger school buses.

Up against the governor almost 100% of the time.

He could have held it down for a couple minutes straight and it would have been fine.

There are guys who run nitrous and tuning to the 7.3 and they still take a little bit to break. Probably one of the most durable engines ever made. Heat from tuning and long periods of over revving seems to be what kills them. I doubt hitting red line would do anything to it even with the mileage you have.

I think you're fine. However, how did you have the cat removed? Did someone specifically charge for that or something? The 7.3s are non-catalyst motors (at least mine is).............no cats, AFAIK.

Edit: After quick Google search, apparently some 7.3s have cats. Now I know, lol. I still think your truck is fine.

the 94-97 square body 7.3s and the early 99's had cats.

Your dad probably just blew out some old soot that needed clearing out anyway. I've seen those engines go through straight hadies and keep right on going. That's why we have rev limiters/governors.

Now you just need to replace the down pipe.

I have the round downpipe, not the restrictive flat one like the 94-97s.
