i think the big prob with diesels in the mud is wheel speed. yeah they have lots of torque but it comes at low rpms. you need the low gears to keep the torque but you loose a lot of wheelspeed. when this happens you lose the ability to self cleen the tires. a trail rig can use the diesel for the fact you dont have to spin 6k to climb over a rock if you have built your rig right and you have the crawl ratio for rocks or trails. but in big mud like what quads building for you need the wheelspeed to clean the tires thus making more traction and further threw the mud.
i have a powerstroke, its not stock with a 5 speed, when i wheel it, moderate mud, does fine even with 3.50 gear and 35s, but when i get into deep mud i still have the torque but doesn't have the wheel speed rpms are low and it sinks like a rock, i still like it, but for mud i'll stick with gas, don't know about rocks all i have is mud and snow
most the guys i seen when i lived in florida ran big 66in float tires with there diesels to keep them ontop the mud as much as possable. then they had no prob they werent diggin down just ridin across the top. still not very fast.
so im pretty sure the mud diesel isnt a good idea, but i bet it would be great for trails and such. I guess ill have to build a trail rig instead of a mudder, to be diesel powered. I like diesels, always have, even before they got "big" and popular. Thats just how i roll.
I think it could be done, but you'd prolly have to run an automatic, (ugh) the lack of rpm could be made up for if you can shift into a higher gear while you're moving to keep the wheelspeed up, but this would be with an engine pushin REALLY high torque numbers, which means you'd have to have an extreme tranny built as well as well.
So I will prolly stick with gas on a mudder, trail use I could see a deisel being really nice.
Oh, I once saw a dodge truck with some kind of dumptruck engine in it at a bog, it was an absolute turd, he had crazy torque, but no rpm, there was a subaru wagon that went further in the bog than he did.
Yea i wasnt thinking THAT big of adiesel im sure that would sink you like a brick. But yea with extreme engines come extreme tranny's. So yea, the trail rig, theres an idea though....
well alright then. I know quad has some expierence in the mud boggin side of things, ill consider it question answered.
Do you think that a Properly built diesel could be a good bogger?
dont get me wrong i know of a few deisals that are just knarly.....one with prob. 700hp1300tq 66 r2's 5tons that is pretty awsome and another witht eh 66"terras and prob. the knarliest deisal in the world....but they arn't like having 50mph wheelspeed either.....
