Does anyone know what ford did to increase the power of the V10 in 2001? And also why do the full-size vans with the V10 have less power than the trucks with the V10. Thanks. Benjamin

 

My understanding is that Ford changed the intake manifold to a plastic one, changed the head design/valve angle and updated the computer program. I knew the 98 vans had a 265 horse V10 but I didn't know they still have different ratings.

 

The e-series vans use the same v10 but have a more restrictive airbox assembly simply because of packaging. There'smore room under a SD hood than van (this is course is heresay...but that's the story and I'm stickin' to it.)

 

 

my 2001 f-250 sd does not have a plastic intake on it its magnesium i belive, ford has been tight liped about the hp changes on 2001 v-10 most people say it was some computer & cam profile changes and one magazine I read a article they said insiders said ford changed intake valve size I dont know this for sure but I do know before I done any work on my truck the basline on the dyno figurs were way off from the factory ford says 2001 V-10 has 310 hp/425ft/lb torque mine had 285hp and 390 ft/lb torque at rear wheels

SVO, your numbers kick #####, (almost to the point of unbelievable)! Ford's numbers are from the CRANK!!

 

Ditto!

 

BTWY, the 2002 specs are 5 hp and 5 lbft lighter on the vans than on the trucks. Maybe due to space restricitions for the intake/air box?

 

>mine had 285hp and 390 ft/lb torque at rear wheels

I would have assumed that Ford's figures were flywheel #'s not rear wheel #'s. Am I off base?

 

Yes, Ford and every other manufacturer publishes dyno numbers from the flywheel. That's why I think that SVO's numbers are incredible (or erroneous) For the engine hang-off equipment (alt., wtr pump, power steering, fan, A/C etc.), the transmission, transfer case (if equipped), and axles to eat up ONLY 25hp is incredible. I want his driveline!!
The above mentioned stuff uses around 85-100hp. It's reasonable to assume that around 205-225hp gets to the rear wheels. I urge you to check out NoMO's and Wawii post under the thread entitled "Guess I'll go first..." by yours truly. They actually post their dyno's...Dem's da facts in ritin':7

 

I think the numbers Ford puts out are "net". Not sure about what all is installed, but I believe it at least includes the losses associated with the alternator.

Also, if the intake plenum is metal, it must be an "early" '01. I had an '00 F250 w/metal plenum, but my "late" '01 (aka 2001.5) is plastic.

 

no mo,
my truck was ordered Dec 2000 and purchased in febuary of 2001 my freinds sd was ordered in april of 2001 and purchased in july of 2001 both have metal intakes on them and both assembled in mexico I dont know if that would have any thing to do with it or not

 

I bet we are talking about the two different "intakes". :-) The UPPER plenum is metal- with runners out to each intake valve. The lower one is "plastic". Before '01 (at least with my '00 F250) the lower plenum was also metal. I think that's what V10man was talking about.

Check your engine and see if it's the same. My '01 was also built in Mexico (2/01).

NoMo, how do you find out where it was built?
BTW, my manifold is plastic also. ('00 V10) Plenum is cast metal (aluminum?)

 

[updated:LAST EDITED ON 15-Dec-01 AT 01:19 PM (EST)]I'm not sure about the Excursions. The trucks are assembled in one of two places- Kentucky or Mexico. You can tell which plant by the VIN. 1FTxxxxxxx indicates a KY truck and 3FTxxxxxxx indicates a "Mexican" truck. Also, I think the placard on the door jamb tells where the vehicle was put together.

You probably already know this, but...
All of the gas engines are built in Windsor, Ontario Canada.

On EDIT:
OOOPS! I can see how my previous engine/truck-build statements could be confusing. Hopefully, the above will clarify what I was talking about. :-)
