See this thread for what I'm getting done and tell me what you think my numbers will be. The exhaust and intake along with my tunes are the only mods to factor.

I have to talk to Anita on Monday about the headers. If She says their not emissions legal here in VA then I am gonna have to pass on them.

So make it two guesses...one as I have planed to have everything done. The other with everything but the headers.

 

It all depends if you are going to put all of the stickers on or not...

 

haha

 

hp- 287
tq- 315

hopefully alot more.

 

Those actually don't sound too bad. Maybe will see a little higher, but I wouldn't expect a whole lot more.

 

265 and 310.

 

Let me make my guess

With headers
279 HP
319 TQ

Without
260
287

 

Just curious what hp did it come with from factory? my 08 screw is 4.6 and rated at248 so i just assumed a 5.4 would be around 300 or so from factory..that is the only thing that i dislike is that gm has a 4.8 that does 295 and there 5.3 does 315 i believe. Ford seems to have fallen in the hp range... but man i love driving my ford....

 

I'm guessing that their numbers are at the wheels and fords ratings are at the crank?

 

The 5.4s are in the 220 range but some of the newer models are showing a little bit better numbers.
