Buckwheat, thanks for responding.
Your experiences are what I hoped could be accomplished. I know the engine has to be built to withstand the hp levels, I see your set up list displacement at 5.0. May be a stroker kit would be advantageous while I'm getting forged internals (thought I think I recall Zack and another member discussing displacement vs boost comparison for power). I trust Justbob statements about excessive boost. Are there concerns about the limits of displacement a Trilogy can support?
RubberCtyRauder, you earlier asked which pullies I have. I only have what is supplied in the Trilogy kit. With the Metco kit, options may become available. I saw the recent thread about heat exchangers and choices for that. I plan adding a Killer Chiller kit as well.
I have a copy of Sean Hyland's book on 4.6 liter Ford's, had it a few years. I thought I remember folks saying some info in the book is misleading. Does anyone recall that as well? Are there other sources of info on building our engines that surpasses this book?
Thanks again for everyone's responses.

If I had to do it all again,
source all the cobra parts swap, cobra engineering midplate, jerry's brackets,either any TVS blower, oem(13-14)or whipple 2.9 for shelby would work and keep it all on D/side inlet, JLT cold air for shelby.....
obviously above would have a built short.....
even if i had a stock short i would go this route and run any 07-12 factory blower and it would lay down 500 rwhp all day.

While the stroker is a good idea, what would end up happening is psi would decrease from the engine breathing more efficiently, torque would increase and hp would stay relatively the same. Where people benefit the most from a stroker is making the same power with less psi, and simply adding a smaller upper or larger lower and getting back to the psi you were at before with the stock stroke. This is where you see the real benefit of the stroker.
You would run into two problems here, first is just finding smaller pulleys or larger lowers that work with the trilogy and if by chance you did find some the second problem would show up, which is over spinning the trilogy to simply get back to the psi you were at before, this is when the trilogy becomes too small of a blower and isn't running efficient anymore. High iats, heat soak and all the other issues that come with heat from a blower spun hard.
If you are dead set on the trilogy, porting it is a great idea but before you even do that you must make sure you have the necessary pulleys to take advantage of the port by increasing the boost and honestly to simply hit your hp target numbers

Trilogy 93P made 416/418 @15#'s boost, stock internals,stock exhaust ,
2.6" upper and a Thump tensioner.
It had 100,000 blown miles when I Turned up the wick from stock 3.4 " .
Not one of my brighter decisions.
Against my tuners recommendation ,I did it anyway.
It made 12.2@113 .
The car was a beast , If I can just duplicate the performance of the
Last time it was in that range, I am thinking now just get back to That range.
It was a hand full on stock tires and brakes

While we are not running a trilogy, it is still a eaton m112, trilogy used ford parts for their kit and the rear inlet was already designed just used on a lightning, trilogy being clever Used the cobra intake & intercooler and bought the supercharger from eaton already setup with the lightning rear inlet. The lightning put down 380 hp on a supercharged 5.4. WoW they left a lot on the garage floor and the cobra did 390 with 4.6. The 5.4 was a two valve engine but trick flow makes heads for that and add a tvs to that sounds like a CV build

Where is NateHawk?
His car is in that area, Posey Ported Trilogy.

Hey Rich, Im here lol.....My car was dyno'd a few years back making 538rwhp on a Trilogy with a posi port, upper and lower pulleys, on an Aluminator Motor. Thinking about getting the blower rebuilt soon since its been running for years. Wanna get it serviced before anything really goes bad.

Great Googly Woogly Natehawk!
Do you recall your pulley ratios and max psi? I searched about Posi Performance and saw where he decided to close shop due to family obligations. I think was on SVT Performance or The Chicago Garage.
Steigmeyer (?) had plenty of comments, both good and bad. Has anyone on this website used Jokerz?
Thanks to all who have taken time to respond to this thread. A lot of good info has been put out there. I hope someone else besides me will apply this to their build.
And if anyone has more to add, please do.

If I recall it's a 3.0 upper pulley 4lb lower and 18psi. This was all before a few extra mods so she probably have a lil more ponies to put down.
