ruff estamate with a manual. im tryin to get a round about figure before i dyno my car next month and all the calculators are telling me 395 hp and i know that crank hp. just an estimate

 

12-15%
w/ your mods i'm thinking around 305-310 rwhp.

 

Ford Drivetrain Engineer at the New Model Introduction (2005 model) stated the following.

Base GT (M5, 3.55, 235/55R17) loses 12.9%.

18" would be a little higher and 3.31 would be a little lower.
A5/3.31 looses about 3% more than M5/3.55 in my opinion based on differences I have seen.

SAE numbers are at a density altitude of almost 2000' (note the 29.234 Pressure and 77F temp).
So if your 110 mph was at 0' DA (Standard Correction) you are going to be down 20 rwhp SAE.

Figuring race weight of 3650 lb + 110 mph trap at 0' DA I get 330 rwhp Standard. Thats roughly 310 rwhp SAE. 356 bhp SAE.
Thats using this calculator which is the one favor. http://www.modulardepot.com/hpc.php

Stock early-2005 makes 300 bhp on 87 and 305 bhp on 93 (From same Ford Engineer).
Later cars (no Vapor Trap in Intake) likely make about 6-7 bhp more.
