so i found out one day if i put my truck into 6th gear at about 10-15 mph and i lug the engine bad i can smoke out roads. However before i do it much more i want to know if uts hard on my truck to do that and if i will hurt anything by dropping the RPMs that low

 

I dont like doing it, that is a massive strain on the engine.

Andy

 

me and my uncle will not drop gear in some spots unless the rpms get below a certain spot. my uncle drives his like he did his coal truck.

 

ok so it IS hard on stuff......what could go wrong if something did go wrong, like what could break

 

Just think about how hard it is putting all that strain on the engine for no reason. Listen to how hard the timing tries to advance.

Andy

 

im not gonna do it again to listen to it................but like what would go bad if i kept doing it

 

More strain on the Vp and the valvetrain is the first things that pop into my head. The added timing causes more preasure in the cylinders.

Andy

 

well let's say it's a 12valve..... and i lug mine locked in drive or overdrive..... what could be hurt other than washing my cyl walls down with fuel?

 

Im not sure, I know that when I lug mine down real hard it rattles like a small block with the timing advanced to far.

Andy

 

i've never heard mine rattle. i have stock timing on mine and have put it on a 65% load on the dyno and heard nothing..... the dyno opperator wouldn't go higher as he thought i was going to break something..... my truck or his dyno....
