RE: F550 Chassis Super C power ratings
the claimed GCW is 19000 and the GCVW is 35000. Would it be possible to re-tune or even advisable?
It is almost always possible to retune, although some parts swaps may be required, I don't know the details for the various versions of the PowerStroke. I know a lot about bringing 160-250 HP CTDs up to the 300-350 HP level, and a little about building those for drag racing and tractor pulls.
I don't consider it advisable, the whole point of having different engine ratings for different duty cycles is to meet customer expectations of service and longevity. In the search for more power, where do you stop? More important, how do you plan to use the extra power? To tow a heavier load, or to just cut a couple seconds off your acceleration to freeway speed?
Unless you already have a racing engine with an expected life of a few hours or less, you can always up the ante, especially with supercharging and computerized engine controls. A 600 HP 6.7 Powerstroke is not much of a reach, but it is not going to put out that kind of power for 250,000 miles.
Look at it this way. The last of the piston engines for large aircraft had takeoff ratings of 3000+ horsepower. They could sustain that for something like two minutes to ten minutes before immediate self-destruction. Same engine might be 2200 horsepower maximum sustainable, good for a couple hundred hours. Cruise power might be 1600-1800, 300-500 hours. They needed flight engineers managing the engines and logging times and power settings, to optimize engine life, and determine when to rebuild. What you had was a 2200 HP engine with a 140% power setting for takeoff. The extreme cases were about 180% power.
Modern computer controlled engines have, in the pickup truck versions, the equivalent of takeoff power. The marketing department demands this. But the computer engine management goes only so far as to avoid the immediate self-destruction. Although it may be logging other uses of power, it is not set up to tell you "engine life nn%" or predict " nnnn hours before overhaul."
So what you get in a truck that might need to put out 100% power 100% of time, is an engine limited to 100% power. You don't get the 150% output setting provided as a sales tool for the F-250.
Well said. Thank you

F550 Chassis Super C power ratings
The new 6.7L diesel motor that Ford offers for the F250 - F550 has HP and torque ratings of 400hp and 800 ft lbs. The Four Winds brochure lists the motor as 300hp and 660 ft lbs, significantly lower. Is this a misprint or do theyde-tune the engine and why would they do that?

RE: LP vs Gas vs Diesel Generator
I'm looking at the new Four Winds F550 chassis Super C. Apparently it has a 68lb mounted tank which I believe equals about 17 gallons. The coach also has a residential fridge which runs off the inverter. I boondock a lot so a nice battery bank and solar is probably in my future. I might also weigh the cost of a nice quiet Honda gas gennie or a big auxiliary propane tank.

RE: New Super C Motorhomes from Thor Motorcoach
Well, I went down to Giant RV in Montclair, Ca. to check out one of these myself and I just loved it. The fit and finish were above average and the drive will change your mind about loud rough driving Super C's. In fact, I liked it so much I bought it.
What I liked:
The towing power of the F550 with a 35,000 GCWR will finally allow you to use the capacity of that 10,000 lb hitch. Its under 35 ft, Dual A/C, Whirlpool residential fridge, 1800 watt inverter, auto gen start, self leveling jacks, ample storage, residential king size mattress, big shower, electric awning, electric step. I also liked the overall floorplan and large bunk above the cab.
I've owned toyhaulers mostly and one diesel pusher and this is my first C Class. I think I'm gonna like it.
I'll post more with pics later.

LP vs Gas vs Diesel Generator
The coach I'm looking at has an LP onan generator. I've always owned gas and diesel gensets. Which leads me to my question. What are the pro's and con's of each fuel type?

RE: New Super C Motorhomes from Thor Motorcoach
Well I was able to walk in to one of the Chateau Super C Motorhomes, it's the sister to the Four Winds Super C. I liked Ford's interior cab, it's a lot more refined than what I've seen in most others.
The motorhome's bed above the cab was very big, largest I've seen. Two adult could sleep up there very comfortably. I wish I could replace my fridge with the one in this coach but I measured and it just can't be done. :-(
So what was your opinion of the fit and finish? storage? appliances? anything else that wow'd you or you didnt like?

RE: Saying goodbye to my Voltage
Too weird Scott. I just sold mine as well, and after only a couple of weeks on Craigslist and GD.com
For me, it was TT, then 5'er,then Class A, back to 5'er, and now going to a Super C. It really was a tough choice as neither setup is good for everything we do. In the end it was the wife's traveling business that was more conducive to a Moho, that and it seems like we just dont have the time anymore to ride.

RE: King of Hammers Trip
Kev, did you talk him into Carne Asada? That would be worth the trip in itself! Yea, Cisco!
I left on Saturday the day of the big feast. He had 40lbs ready to cook. I shoulda stayed.:S
Saw 66 and we talked about you a bit. Hope to ride with you soon. Rubicon this summer?

RE: King of Hammers Trip
Took the Voltage to Johnson Valley to watch the King of Hammers race. Camped with the utvunderground.com la Familia group.
I would have sent greetings to Frank and his wife if I knew they were going to be there.
We're looking at possibly going to CalCity at the end of April and anyone wanting to ride is invited regardless of vehicle: CalCity Gathering
Yes, Cisco and Vicki are good people!

RE: King of Hammers Trip
it was nice to meet ya at the fire kevin
Well what da ya know. I had no idea I was camping with dot net folks. Whats funny is when you told me your name I knew I'd heard it before, just not sure where. Perhaps we'll get to ride next time. With the race going on it was way too restrictive. I got kicked off the course a couple times. Good to meet you.

RE: King of Hammers Trip
if you like it so much please go to savethehammers.org and same on facebook. The Sec. of Navy signed the R.O.D. that will expand 29 Palms Marine base into 160,000 acres of Johnson Valley. 80% of the race course you saw will be GONE! J.V. as you know it will be GONE if this happens.
We are about to commence the second of a possible three rounds of defense of our beloved OHV area. Pleas stay engaged and get involved or you won't be there next year.
Good point Nather. I've signed the petition and posted links to petition on my facebook page.

I havent heard numbers yet but something like 40,000 people go and there were thousands of toyhauler, RV's, and enclosed's strewn about the desert

I missed the UTV race on Thursday but Mitch Guthrie and son won again with UTV Guide.net's Jon Crowley right behind him by +.16. Matt Enoch took 3rd and that was it. The other 32 DNF'd. This was by far the toughest offroad UTV race in history.
The main event on Friday was incredible to watch. I caught Robbie Gordon crawling up Wrecking ball in this video

We put in some desert miles and did some rock crawling but kept getting kicked off the course, lol. Heres a shot on top of the sand hill looking toward Big Johnson

I love Johnson Valley for its immense size and varied terrain. We hope to make it next year!
