red not to rain on your parade and i love what your doing and i love 5.4 swaps but are you really only getting 279?

 

HP sells cars, TQ wins races ...

 

the highest of that set was 281/333 but yeah... about 280.

with shorty headers that's about all you can expect. You might be able to squeak more top end from stage 3 heads and a stage 3 cam but not with street oriented parts unless you put longtubes on it. Without the added scavenging from the headers the cylinders don't fill as well as they could. Adapter plates also cost me a nice slice of power and I had a really really soft tune on it since it was the very first run after break-in and I didn't think the fuel system would keep up (it didn't). If I'd had the tune at full wick it would have easily slapped down 295-300.

With the longtubes and a fresh tune I'm expecting somewhere around 330/350 to the tires.

that's a fact. Since hp is a representation of tq (much like a description is a representation of a photo) it doesn't tell the whole story to pay any attention to hp #'s. Maximizing average tq production throughout the rev range is the idea.

 

503/560 for now

 

How musch more does the 5.4 weigh than the 4.6? What RPM's are you making your max power/torque?

 

around 100lbs all in.

max power depends on the build. I made peak hp at 5500 and peak tq at 4000.

Updated dyno numbers and combo description for mine.

 

2003 mustang 5.4 .020 over. Trick flow heads. Stage 3 mhs tfs cams. 10.8 CR. I think there is more in it...

 

Is that with nitrous or are those trick flow heads just that awesome cause NA thats super bad ***

 

Those heads and that 11:1 aint hurtin' either.
Congrats 330 VERY NICELY DONE!!

 

all engine

 

from the fuel lines I'm sure there is some more in it. But your dyno graph looks like a 4.6 with 9-10psi of boost.

 

Yeah the fuel trims are hard to nail down in the car. Bank 1 runs a little leaner then 2 so I'm in the process of trying to find out why. Also, it gets very lean when the load is high and when you get up near 4000 rpm the thing takes off. As far as looking like a 4.6 graph, your right. It feels just like when I had a vortech with the old engine.

 

awesome power man. Great job!

Make sure and send a copy of your dyno graph to bob at HPS. He'd appreciate the hell out of it.

I told you guys the TF heads were going to make 400rwhp cars. He's at 380 to the tires and I don't think he even has longtubes.

 

Nope. Thats with JBA shorties. Long tubes to come after a k frame

 

Are you running the box stock TF heads or have they had work to them?

 

Stock 44s w/ flat top pistons

 

Those number look reay good.

 

I want one....

 

I hope you don't mind, but I'd like to share your graph and results on another forum. Can't wait to see what you make with the tune done and then long tubes! excellent combo!

 

go for it

 

newbie here but been in the crown vic forums for years.
glad to share some info with you guys
I did the 5,4 swap last summer on my crown vic and here are the results.

2004 crown victoria 5.4 5 speed manual
5.4 engine off an 2004 f-260
hps intake
accufab plenum with stock 70mm tb
comp cams xe262ah
underdrive crank pulley
mezeire electric water pump
pushing 240 hp 307 lb/tq at the wheel.

numbers in yellow are my previous run the one in green that cant be seen are my curent ratings

Note that the dual exhaust is still stock with 4 cats and 1.7/8 at the smallest spot
previous run on the sheet is the one with the stock plenum a 65mm tb and no underdrive pulley and water pump

 

What intake are you using and how big are the injectors? what exhaust? do you have any sound clips? thanks

PS you the man!!!

 

I own this car now and o do I have so many questions...lol

 

Its running hps intake manifold with 42lb injectors and jba shorty headers with an h pipe and flowmaster 40 series out the back

 

gt4ftw: well, it's getting kinda lean at the top end. I don't know if that's fuel pump or maf xfer. Hoping there's a 90mm maf on that cuz at 400hp you're just at where it starts to hit the top of its range. I'll bet there's another 5-8hp in it. Maybe a bit more. See if you can find out the cam timing. You might pick up a little top end and stretch out the power band by retarding the cam a couple degrees.

 

Its running a 90mm maf and it just doesnt want to move until 4000 rpms...i think tuning issue but i need to get with the original owner to try and figure more out..input is greatly appreciate it i have a turbo setup i want to throw on it but i dont know if the build can handle it or not im not a guy that is very big on spray either

 

Little sound clip sorry about the quality
