my 7.3 doesnt need to be a 5.5k rpms to sting mud. diesels are a low rpm motor. thats they way they work. your v10 needs the rpms to make power and sling mud. lets put it this way. have both trucks at 3.2k rpms and see who is slinging the mud. at 3.2k rpms im doing 75 down the freeway.

you keep on wishin.
just about topped out huh, you must have owned my truck before me since you know so much about it. its weird, i dont even know what my truck tops out at yet. never had to top it out, all ive raced is ***** v10's.
and i dont need all those rpms to pull your truck out of the mud after you dig yourself in a hole from slinging all that mud haha. just good old fashioned power!

Why are we rehashing almost the EXACT same argument that's been beaten to death over the last 30 pages?
mountaineer27 seems to be a typical PSD guy who believes that because it's a diesel it's automatically better in every way. Not likely, but go ahead and keep stroking your ego.
And, for what it's worth, as we hashed out on or about page 26, horsepower can't lie. A STOCK 7.3 is really no match for a stock V10. Modded is obviously another story.

sorry, but you don't have a clue how the 4 stroke internal combustion engine works. It takes two revolutions of the crankshaft to complete one combustion cycle. 4 strokes, 2 up and 2 down. Piston cycle is equal to crankshaft rotation. The camshaft makes one revolution for every 2 crankshaft revolutions.

Hmmm.....
this is so much fun !!!!
Now we are slipping into the gearing comparisons again
Topped out @ 75 ???? I WANT some o dem drugs
3.73's in mine has been faster than I want to say ......
tires are the limiting factor to safety....
you are right I can't go 5.5k rpms, or nor do I have to as I'm waving bye-bye to you in my rear view
Stock we are limited to about 95 or so,
removing that limiter will allow me to runup to about 4250 rpms which puts the speedo WAY faster than it should go without speed rated tires....

Part of the confusion, or ignorance as you call it, is that people are highly focused on peak numbers. Your statement is a good example of that confusion and the 5.4L (~300 Hp) vs. 7.3L (~230 Hp) is the perfect answer to that statement.
Driving a vehicle is dynamic. An engine isn't an on/off switch that goes from idle to peak torque and/or horsepower. You have to drive up through gears and run at all engine speeds. The engine that makes the most average power during the race wins. There is no way in hell that a 300 Hp 5.4L can out tow a stock 7.3L. Hook up a load and the 7.3L makes greater power most of the time, while the 5.4L makes greater power a little bit of the time. The heavier the load the greater the disparity. And don't give me some wild idea that you're going to put 8.xx gears in the rear axle. You want a tow rig not a rock crawler.
Now, if you don't believe me then please explain why a 400 Hp Honda Civic engine isn't a good choice for a heavy truck. We all know it is true... but WHY???

Are you running 5.88s in that thing??!!?!?! I'm at 2250 at 75mph. If you calculate it out you are looking out at topping out around 118mph at redline (3400rpm) for a stock 7.3L (3.73s and stock tires). I'm sure the 6.0s are even faster with the 5 speed Torqshift.

Holy crap, Mountaineer27! Look at my darn signature!
I have NEVER even so much as driven a V10 SD. I do, however, own a 2008 F250 4x4 with the 6.4L PSD. Do I really need to spell out what those three letters mean?

Now our bench racing is back to Top End
Thank you - I think I pulled a muscle giggling at that change of direction....
You guys run for political office ?
Admin - what's the next level after Post Fiend ?

hmmm, was just about to go looking for a net calculator to do just that -
but ----- that giggling got me
a 6 oh with redline @ 4250 and 3.73's with 16" tires SHOULD go past that....
It's pulling HARD at 100, but I won't go that fast on my tires....
and would thik aerodynamics would come WELL into play with my "shoe box"

Will it still sling mud at 5.5K RPMs though?
