6.2 gov spring

ya its the orginal i rebuilt it a few years ago when i bought the truck but never touched that. ok so is it bad when it bounces off? my step dad thinks its horriable! when it does but maybe he thinks that cause it out pulls his 00 24v cummins hes 100% stock lol i pass him up hills towing our horse trailers to horse shows

No harm's done when you bounce off the governor...the governor simply cuts off fuel until it senses that the RPM's are back within "safe" range. With that said, IMHO making a habit of running the engine right on the governor's likely not a good thing for engine longevity, and certainly I wouldn't run a stock engine beyond the factory governor settings...

tim-
i'm bouncing off the governor on the F450 carrier all day long. it's the price you pay for 5.13 gears. it does fine.
taking it up to 4500 is purely a personal choice. for those who want to do it....great! it's your motor. if it blows up...don't blame the truck.

Engineers also invented the olds 5.7, challenger, columbia space shuttles (plus many other accidents), mixed up imperial and metric on mars missions, etc

Engineers can and will screw up too just like anyone else can. *cavitation*. Make it cost efficient, decently, with an acceptable failure rate.

"By the time the 6.9L reached production, engineers had tested the design for a combined 52,000 hours, and racked up 815,000 miles worth of field testing."
How many hours did IH test engines at 3000+ rpm, 4000+? How many engines, did any fail and if so how? I dont know. If anyone does it might help us understand better. Otherwise its everyones best guess. The harder you run an engine the shorter its life. We all know that (i hope).

Never claimed otherwise...just wanted to make sure that the OP understands that there's potential danger involved

Yes they can....columbia was a failure due to damage...not an engineering failure. My guess with cavitation is it came down to some manager or bean counter telling them to cut costs. Ill bet 90% of enginnering failures are a result of politics and economics. Engineers dont typically think of that stuff. Its some idiot in a leather office chair and a business suit saying "i dont care...it costs too much...lets change xyz" with little to no technical knowledge.

The 5.7 olds...well...your right...sometimes engineers screw up...they are still human lol
