****, I'd kill for that 400 HP to the crank let alone wheels!!!!

 

400 hp is about right. The stock Linconl 5.4 had 300, so 400 would be about 30 percent increase, which is just about right for 8 lbs of boost.

 

wait.... he has a 1998 Navigator..... The engine I bought and swapped into expy was out of a 1998 Navigator.... Is mine 2V or 4V???????

I have SOHC... nvm... but there was two options for the 5.4 in 1998?? 4v is the Initec?

 

latest

Can anyone tell if this is 97 or 98?


this is where I got my engine from. I could sware it was a 1998, but I have a SOHC 5.4 though?!

 

I only ran 6 psi on my 2006 5.4 3v...it was rated 412 HP/477 TQ at the crank...about 300 HP/370 TQ at the wheels


seems like that 4v would flow more...and have a higher bit of HP/TQ with 8 PSI

 

Are thos actual numbers or advertising numbers. Most centrifugal superchargers advertise a 30 to 50 percent increas in power. I think the 400 horse would be a little conservative, but withing the realm of reality.

 

actual #'s...Roush doesn't play HP gains. They advertise what they get.

I had the Non-Intercooled setup and the horribly safe Roush tuning...was going to get custom tunes...but never was able. then traded the truck in


Non-Intercooled on the 5.4 3v = +112 HP/TQ
Intercooled on the 5.4 3v = +145 HP/TQ


I know the Intercooled guys were/are running 330-340 RWHP...which is right in-line with what Roush says it is supposed to add...especially after you figure the 4 speed eats almost 100 HP

 

The Roushcharger is a roots type blower not a Centrifugal. Vortech only shows a 140 hp gain on the cobra at 10.5 lbs of boost. Powerdyne shows about the same on the 3v Mustangs. Historically powerdyne blowers have not been known for major power producers.

 

yeah...positive displacement rocks. I miss mine

but only +140 HP @ 10 psi...what crap

 

Vortech, has issues. That is why most of the PRO 5.0 guys run Procharger, or turbos.

 

Crank. Remember, this is the orginal 32v that had a pathetic 230hp. run that through the auto tranny, 4x4 drivetrain, it had like 180 to the wheels (PATHETIC)

Its really hard to tell in that picture which year it is, the easiest ways to tell were interior, and I think 1999's had turn signals in the mirrors. The cluster was also different. If that lincoln emblem on the rear side glass is black, i think that means 1999.

 

As far to my knowledge, the navi only had the 32v in 98
It did have 325 pounds of torque in that year though

 

The 98 had the standard 5.4 as found in the Expedition. 1999 forward had the 32 valve 5.4 rated at 300 hp.

then how does 98navi have a 4v???? or does he?

 

he shouldn't have, unless some one swapped it in. Of course there is no telling with Ford, they could have actually started teh 4v on teh last few 98s.
