I'm not sure if this has been discussed but I was wondering what the differences are in the 4.6 used in 07 Sport Trac to get it to 292 hp vs the 230 hp for the 4.6 used in the F150's.

 

Probably a difference in the way they are tuned. The sport trac is probably tuned more for performance rather than a load bearing torque engine such as the one in the F150. It might also have the three valve design vs the truck version of the 4.6 still only has two valves I believe. I bet they might improve the F150 4.6 in the next couple of years since they have shown in other vehicles such as the mustang and now sport trac how much power they can actually get out of the engine.

 

3V vs 2V. The same engine has 300hp in the Mustangs.

 

Thanks, Thats why I like FTE so much. People are knowledgable and willing to share. I guess that I won't be able to pump up the volume on the 4.6 in the 06 supercrew I just purchased. Down here in Texas they have an additional $1,500 rebate on Supercrews with the 4.6 and XLT package and I debated long and hard before taking the money.

 

Put a huffer on it, and you'll beat that 290 HP

 

newbe ?? I'm sure but what's a huffer?

I just bought an '06 F150 but wife made me trade in my '98 TA to get it (LONG story but I'm military and "need" a truck for moving in a year AND she said I could get another one once I retire in <5 years )

anyway I know the truck won't compair to my TA but that >290 hp sounds real nice I can't afford a supercharger or anything but definately looking at the big 3 (exhaust, intake, chip) soon

 

Huffer AKA Supercharger also goes by the name Blower.

 

ahhh ... blower I know I'm just "old school" I guess LOL I hear huffer I think of some idiot in the corner with a cup of gas goin to town LOL

 

That was exactly the reference I was going for - the kid in the corner...

I did mean supercharger...
