Where's the sweet spot?

[ggranch]

Good news, we will take delivery on the new TV next Monday. It is a F-350 dually, V-10, auto/tow command, 4:10 Posi-Trac, Traction Control. Our old TV has a sweet spot common to F-250, 5.4 V-8s located @3100 rpm in tow/haul mode. It acts like an extra 30 HP at that setting. Does the V-10 have a similar sweet spot and if it does, where is it located?

I have also read in the MOC that some of the engines come alive after approx. 12-15,000 mi. Is this the case with the V-10?

Rich, if you read this (I know you have the 4:30 gears) jump in with your $.02.

Congradulations and good luck with your new truck. I didn't realize they made a dually gasser. We have a F350 Dually but it is Diesel 7.3L with a 4:10 and the best torque is at much lower rpm's. I am sure you know about the Ford Truck Enthusiasts forum. That would be a good place to get more answers on your question.

Bob Our MPG increased at around 12K. You will find that you will get within 2mpg of the diesel pulling the same load.The diesel does much better not towing. Ours runs at @2100RPM's at 65 MPH)fairly level ground) and seems to get the best of everything there, we run in T/H when pulling the 3400. We will not attempt to compare the diesel/Gas..the diesel is of course the better pulling motor however the V-10 will not disappoint you. We pulled every grade on our winter trip at or above the speed limit. Got a kick out of the Diesel guys going around me on those long steep grades 10/15mpg over the speed limit then be at the top at those pull overs cooling their turbo's while we drove by. Oh on significant grades we do not run in cruse control, T/H mode. The cruse will attempt to keep you at the set speed, and it will, but I like to go no higher than 3500/4000 rpm's as although the V-10 are designed to run at high rpm's I do not like the scream at 4500/5000rpm's as it sounds like the motor is going to pull out of the truck. We are in the market for a new truck and it will be the 6.4 Ford mostly because we have never owned a diesel motor and "got to have one) but if the deal is not right we will have no problem staying with the V-10...

Thanks for the input Rich. Good luck with your TV shopping. The dealer had a hard time finding our rig (it is coming in from Oklahoma) and said the factory order time is about 10 weeks. He only needed $500 to place a build order. We got a little more truck than I would have ordered, more options and tires and less gear but our new 5er is due in any day and the money was only $1200 more. Wadda ya gonna do?
