Supercharging a 2003 F-150 Boss

What Vortech did you have? If the Eaton made more power I'm guessing it had to be an A-trim. I sent a Eaton off to Stiegemeier for a port job for a 03 Cobra and we maxed it out at 16.5 psi. and 476hp. is all it made. An intercooled T or XY-trim Vortech would have almost doubled that. Centrifugals are a little more efficient.
As far as the cobra with the eaton, it had something bad wrong or it had a really conservative tune in it. The following was copied from svtperformance an 03 cobra Brian (POSI) did all the porting to it. At 4psi less than the car you mentioned it made 32hp more.
Alright I finally got some numbers for my ports. Details on car are as follows.
2.76 upper pulley only. 1st Generation K&N filter, MRT H-pipe with cats, and Magnaflow catback
With 2.76 upper only and tuned
474/486 SAE boost at 12.5 lbs.
Now with Ported Blower and stock tb/plenum
500.1 SAE HP
Last test was Ported Blower with Ported TB/Plenum This was still with the 2.76 upper only.
508hp/490 SAE
I'm waiting on the torque now and will edit this post. Also hopefully get a few graphs to post as well.
Thanks,
Brian

I am not sure, but it was so good power. My magnum powers at 20psi at 5800rpm is only high 120's IAT's, but after 3 wot runs its heat soaked, so i just ice the intercooler, no big deal. Water meth is my next mod

It was an s-trim v-1 at 10psi. I changed a lot of variables with the eaton setup, motor, cams, headers fuel system. I had in the back of my mind the whole time i wasnt going to like the eaton setup and i would miss the vortech. Man was i wrong i absolutely love this setup and wish i did it long ago.

Obviously you haven't done any research yet so let me help you out!
You need a complete intake assembly like I have for sale and I posted a pic of!
Then you will need everything on this list of parts that Mike sells.You can get the hole installation kit from him like some of us have or you can shop around ,buy some stuff used and get the rest from Mike. Whatever is better for you.
I just bought his hole kit when I did the swap.

After your done with all that you still need a tune for your computer to make it run.

If you start with the blower assembly from Phil you have a very, very good start. A lot of the other parts you can get used of of NLOC or NTHOC or other Forums. I ended up only going to MAD for the fan spacer (since I did not install L/HD water pump) and the IC pump and L alternator and bracket because of his pricing. I was able to do mine for $2600, bu then I shopped around quite a bit. Even found a junk yard with the L IC heatexchanger brackets.

I just listed one that takes a lot of the work out of it
