I think some of thses MPG numbers must be in "2005 mpgs", because I sure don't get anywhere near that with my '02 V10.

V10 fuel usage/vs power

I wasn't satisfied with the hp in my 2003 S-Cab with the V10 so I took the wrenches to it. Before the work I was getting between 12 & 13 on the highway & 10 to 11 in town. Except when pulling a trailer, the load factor didn't seem to affect the mileage much.

For starters I added a larger cold-air intake and short-tube headers matched up to a better less restrictive exhaust. Then I chipped the ignition. These mods brought my hp up to 425 @ 4500 RPM with 418 ft. pounds of torque as dynoed. Oddly enough, my fuel consumption is slightly improved as long as I only use the amount of throttle setting needed to get the job done. Highway use is 14 to 15 now but the in-town is still about 11. Fully loaded I now get between 9 & 10.

One of the big concerns I had before I started this project was over the strength of the drive train; would it be able to handle the increased hp. I'm happy to report no problems and I've not noticed any increase in tranny temp under a load.

I can only compare what I've done to what I see with similar trucks with a diesel and mine will walk away from them full loaded. Before the work it was fairly equal. One other note: The V10 is a lighter engine than the heavier diesel block so you're not pushing unnecessary weight down the road. That gives the front-end a lighter feel on handling. The diesel trucks seem to be "heavy" on the steering.

How do these people come up with threads that are 7 years old? I guess they do use the search function. LMAO

There is no way in hell your going see 425hp out of that V10 with just an intake, exhaust, set of shorties and a "chipped ignition"(whatever that is supposed to be) And if those are chassis dyno numbers you are not going to see 418tq at the wheels either with those mods. Only chance you have of getting close to those numbers at the wheels is a healthy amount of boost which will eventually make the stock rods say uncle.

I didn't even notice that before. I've seen resurected posts from 2001 lately. People must do searches on the net and decide to add their $.02.

Well yesterday I towed a small trailer witha snowmobile and I was getting 12 mpg would have been more but spent a hour idling while we pushed a car up the hill the rd was a sheet of ice then I was spinning pretty good until I made almost to the top then had to get a dodge to pull it the rest of they way so that used a bit extra fuel. The truck is a 04 supercab v10 2wheel drive

Smile 30 Ft Class B+ Motorhome with Triton V10 WDYT?

We had a 1991 28 ft, class A with a 454 and while it got 13MPG (with a good tailwind, going down a 6% grade) it was entirely gutless in the mountains. It was a 3/4 ton chassis but don't remember its GVWR. We are thinking of buying a Lexington 30 Ft Class B+ (that's the new model with the half overhang and full cab) at about 12,000 +/- GVWR - any body have any comment about the V10 engine's pulling power? I'm not so worried about gas mileage as you can't expect much in a motorhome anyway but if the man doesn't have power we will be looking to spend the mega extra bucks on the big "D" and they are real rare in B or C class motorhomes! Help?

Hmm, my bad, the class B motorhome we are looking at is a 2009 Triton V10 and I'm hoping that its gas mileage and power is better than the '91 454. The "man" is still very worried about the '99 triton being gutless and I WON'T go back to 2 x 60 air!

The V10 will haul a load without much problem. reguardless, to help with the power and a bit on the gas mileage, 5 Star tuning has a program for the V10 that adjust the tranny and tunes the engine for towing/ economy/ ect. That will help firm up any sluggish response you find. The V10 is an outstanding engine.

The V-10 is FAR from gutless. Gas mileage sucks (I average 7.5mpg towing my TH, but I'm lifted and run 315's) but I didn't buy it 'cuz it was good on gas, I bought it 'cuz it pulls like a 40 mule team! Decent mileage on a motorhome or a tow vehicle is a misnomer anyway.

It loves to rev (I routinely push mine past 4500rpm's on steep climbs) and has power to spare. A 5Star tune is never a bad idea, I love mine. I had an MH with an older Mark IV 454, it wasn't anywhere near as good as the Triton V-10.

Not only did a ~7 year old thread get revived, but the OP only had a single post. He probably bought an Avalanche or a Toyoter and never came back.



This just goes to prove that forum threads rarely die. They simply lie in wait, regaining strength for their triumphant come back.
