Nobody knows how to add power to the 3.5 NA

I have looked everywhere and I can’t find a single person with any suggestions for modeling the naturally aspirated 3.5 L 2010 through 2012 year. Let’s say to get it to around 305 hp to the wheel. Any suggestions?

There really isn't an easy way to go get more out of it. Ford pulled a little more going to Ti-VCT, but to hit 305 like they did in the Mustang also involved boring it out to 3.7L.

Cold air intake headers hi flow cat maybe and a tune?

Just get a different car lol. Far too many people get so caught up in how to do something "different" that they spend more money and time than if they just bought something faster, or at least switched to a more modifiable platform. If there's almost no information or resources and aftermarket support, it usually means that vehicle is dogshit for going fast.

If you're dead set on the Taurus just save up for a SHO and trade up, at least with those a 5 minute flash tune lets you roast most cars on the road. But if you like frustration then by all means, keep trying with the NA 3.5.

I was just saying the '12+ 3.6 v-6 Chevy Impalas came from the factory with 305hp. As mentioned above, the Taurus SHO would be another great option minus the internal h2o pump.

A tune. The 2012 has 263hp, while the 2019 has 288hp. They have the same Engine block, heads and cams. Got to be the tune.
You can't, that's why. The 3.5L is what it is.

If you want lots of horsepower, buy an SHO.
The only Taurus engine with any chance of upgrades would be the 3.7L, because it's also used in the Mustang and you may find things that will cross over.

Actually, no. The 2013 MY added Ti-VCT (twin independent variable cam timing) to the 3.5L engine, which is what gives it the boost to 288HP, vs. the 2012's 263HP.

The reason why there aren't aftermarket modifications for the Taurus is because Ford sought US patents on its designs.

White Falcon is correct. US Patents protect the designs of nearly all elements of the car, but because the 3.7L is shared with the Mustang, you can find some add-ons if you have that particular engine. Of course, if you have the Police Interceptor then you have the 3.7L already most likely...and it's already rated at 305HP.

None of those - the Mustang, the Impala (or other GMs with that engine like the Camaro), or the 3.7L FPIS have 305 to the wheel. To get that you're looking at a rating somewhere between 335 and 350 hp.

Nope, not gonna do it. You might get a few horsepower from all of that, and maybe those few extra will develop earlier, but it's not going to jump a car from 263 (at the crank) to 305 (at the wheel, or about 335-350 at the crank). A CAI, header, high flow catalytic converter, and a tune (and really, good luck finding that for the platform) are going to be pretty cost prohibitive and have a very small ROI. If you're set on using the same vehicle you have now, find a crashed SHO and do a transplant, or better, buy an adult owned SHO.

The Mustang 3.7 is designed for a longitudinal implementation. I know they had a Police Interceptor Sedan that would take a 3.7L, so there are some transverse implementations. I'm not sure if it's the same part.
Improve aerodynamics, add side skirts, front air dam, rear spoiler, lower car. I got up to 137.9 mph and could have gone higher.
