5.0 with a weight of 3700 (with 200 lb driver) and 435 HP as 11.89 @ 114.6!
I'm pretty sure you can get a GT into the 11s with minimal mods

As others have stated, the above would be correct ONLY for 435 rwhp...not 435 hp. That 11.8 would put that stang more in line with a 600 hp 2008 viper...lol.
Unclear as to which year GT, you are referring to but I have never seen a S197 getting into the 11s with minimal mods. Lots of folk with forced induction don't get into the 11s.

this makes no sense
How in the world could a 1:1 gear be too tall when thats what they usually try to use.... lol

V6 MT w/ 18" tires & 2.73 Gears ... 6500/7000 RPM in 1:1 (5th) would be doing 187.1/201.5 MPH.
V6 MT w/ 18" tires & 3.31 Gears ... 6500/7000 RPM in 1:1 (5th) would be doing 154.4/166.3 MPH.
GT MT w/ 18" tires & 3.31 Gears ... 6500/7000 RPM in 1:1 (5th) would be doing 154.4/166.3 MPH.
... so yea the V6 MT or GT MT w/ std. gears are definitely hitting the 149 MPH speed limiter !!
GT MT with optional gears should be ok in 5th if my math is correct ...
134.8/145.2 MPH w/ 3.55's
or
128.3/138.2 MPH w/ 3.73's

Are the two power levels Ford is claiming SAE certified? If so, Ford cannot "underrate" them. That whole thing went away in 2008. Anyone read anything regarding SAE status? If Ford subjects them to SAE certification, and they are SAE rated at 412HP, they all will be within 1% of that plus or minus. Ford can't make a 435HP engine and then slip the SAE guys a $20 and say "Hey, make it 412!"

my best guess is the numbers were so high in 5th 1:1 that motor trend didnt believe couldnt publish them. the 5th gear should be 10 rwhp higher than 4th or speed limiter and stock gears.
fellas expect 370rwhp and let it rest.

Dude there's too many haters out there to let this happen. I totally agree with you but I'd call it 375 rwhp.

"In 2005, the SAE introduced a new test protocol for engine horsepower and torque.[12] The new protocol eliminates some of the flexibility in power measurement, and requires an independent observer present when engines are measured. The test is voluntary, but engines completing it can be advertised as SAE-certified.
A few manufacturers such as Honda and Toyota switched to the new ratings immediately, with multi-directional results; the rated output of Cadillac's supercharged Northstar V8 jumped from 440 hp (330 kW) to 469 hp (350 kW) under the new tests, while the rating for Toyota's Camry 3.0 L 1MZ-FE V6 fell from 210 hp (160 kW) to 190 horsepower (140 kW). The ES330 and Camry SE V6 were previously rated at 225 hp but the ES330 dropped to 218 hp while the Camry declined to 210 hp. The first engine certified under the new program was the 7.0 L LS7 used in the 2006 Chevrolet Corvette Z06. Certified power rose slightly from 500 hp (370 kW) to 505 hp (377 kW)."
All engineering standards are voluntary until they are adopted by an entity writing code, such as DOT. There are no horsepower laws as far as I know.

ford advertises SAE certified. it is 412hp. drivetrain losses not withstanding. i expect the range to be 365-375 with the average of 370 rwhp.
it only approaches the 370 of the LS-3 because of camaro driveline losses are so high. IRS costs hp. some more than others. look at the mn-12 losses. they are extreme. 03-04 cobra losses are less. vette with ls-1 vs. less tuned ls-1 camaros with less driveline losses.
