A member of the GT350 owners Facebook page just dynoed his 19...looks right in line with the 15-18's.

Imagine that, the same engine making the same power. Also, my sarcasm isn't pointed at you, I love that you posted this. You're the hero this thread deserves.

These 16 vs 18 vs 19 vs R topics are an interesting study of human nature. Marketing is just that.
Well to be fair to the topic Ford had made engine changes.....they just aren't output related.

I drove a 17 and now own a 19. My butt dyno says the 19 is sharper, quicker, though I realize that can be subjective, and less so for pre 19 owners. I’ll be in the same boat once they revamp this thing again.

One major change I don’t see listed is the clutch/springs. Major difference there that truly affects DD performance, if that’s what you’re using it for (non-R’s).

I’ll be getting my 19 dynod this week or next (prob next, due to my schedule), and we’ll have another quantitative data point. But, a good question is do we dyno in 4th or 5th. Seems MT dyno’d theirs in 4th?

is the clutch and pedal feel different for 2019 onward?

How much lighter are the new wheels? That does make a slight difference with whp numbers.

I would love to know what the difference are between 2015-2018 gen 1 factory rims versus the 2019 onward gt350 rims. I understand they are a little wider ( i think 11" front, 11.5 rear now)? They weight more?

The 19s have new, better flowing heads. For a given intake vacuum from the combustion chamber, more air will be delivered. Maintaining A/F ratio means more fuel, delivering more power. The spark and knock tables they have likely haven't changed, so the difference likely isn't much. But the physics says that more power should be there.

Thank you for this article; it was a good read.

I've spent some time with Team Mustang in 2018 (I was invited to see the GT500 before release and see the renderings of the Mach-E - mostly to debate using the Mustang name) where several Ford execs and engineers (who knew I lived in NY and wanted a GT350) told me it would be worth the wait for a '19. They also told me to wait until 2020 to go the Ford Racing School. It was there that I was told that some improvements in reliability occurred during the Predator engine development and the GT350 would "use the same block as the GT500", with "somewhat improved heads". Ergo, I'm poised to believe that the '19 & '20 GT350s were capable of more power.

This happened before in Fordlandia: I recall the 1985 SVO Mustang engine (2.3l I4 intercooled turbo) being "tweaked" mid-year with a redesigned intake, heads, cam and ignition programming with larger 35lb injectors to make 30 more bhp. This went along with the aero-flush headlight buckets, quad-Koni shocks and true dual exhausts. As I remember it, there was quite a buzz in the SVO community about the 85-1/2 making more power. Ford said nothing, and many disputed the claims. But in 1986, Ford proudly claimed more power. Bob Negstad, a Ford engineer I got to know in the '90s who worked on the SVO fondly told me [paraphrasing] "We tried to keep it quiet. It was supposed to be intentional underating. But then every automotive write approached us putting Ford on the spot. Since we only got approval to make 10,000 cars, we just announced an upgraded motor for the '86 and admitted late '85s had the mod. Then we cancelled the program for 1987".

But I suppose the dyno chart doesn't lie. What would be interesting is if the people who wrote the Motor Trend article posted their dyno sheet.

I also had a pre 19 350 and now have a 19. Like others have posted they feel different. While it's true most of us don't know what is making the 19 feel a little stronger, it just does. For me I noticed it seems to sound different and pull harder above 4k RPM. Not sure about this but I like it.

I don't think it is just a feeling. Look at the reviews and 1/4 mile times, they are trapping 1-2 mph faster than pre-19 models, much closer to R trap speeds.

Rolled over 1k miles today, so I am ready to schedule the dyno.

Should I get the first oil change before or after the dyno? I know both is the safest, but that's unlikely unless someone can give me a seriously good reason (due to cost for what seems like overkill). If it matters, I drove fairly spirited for street use after the first 300 miles. I def didnt baby it like I see some folks say they're doing (no hate, just comparing approaches).
So, did you ever dynoed your's?
