These dynos are good for ballpark figures and talking points/bragging rights. Dynos need to be calibrated and no dyno has the same atmospheric conditions everyday. Also there are several different correction factors that will change the outcome

If that is SAE correction factor than 428 from the auto is good. If that is standard then not so much. Wish they showed what correction factor they used.

Performance vehicles are all about Performance. The numbers do matter to most people. Competition is human nature and while you personally might be perfectly happy with your Darkhorse possibly not out performing the 21 Mach 1 there will be people who are definitely not happy with that. If...

Normally I agree with you but at the price they want for these S650s especially the Dark Horse, out performing the outgoing model shouldn't be in question.

The S650 gained weight, it lost torque, and allegedly gained a small amount of horsepower. The dynos and professional testing and now owners in the wild have discovered it isn't performing much better (if better at all) than the S550. The A10 dynos have all been done in higher gears due to the...

Yes. I didn't want to get into gross vs net lol.

American cars 100% positive advertise engine horsepower not wheel.

Steeda did use premium gas for that run (which was the best run btw). The reason I say 408 is "meh" is that GTs are making the same power. And the 21 Mach 1 made the same power. And yeah same dyno but different day the 21 Mach 1 is supposedly 20 hp less than the Dark Horse yet actually Steeda...

They say in the video they drove it 180 miles and put 93 in the tank before they tested it lol. 408 is.....meh.

These numbers aren't sandbagged lol. The S650 gained 20 horsepower and 130 pounds over the previous S550. Were you expecting GT350 times?

Oh I see I misunderstood you. Apologies. I'm not sure if the MT-82 has it or not. Good question

No lift shift and rev match are 2 different things. No lift shift means you never have to lift off the accelerator when shifting.

Ford already stated the only thing keeping the GT engine from matching the Dark Horse at 500 hp is the tune. The Dark Horse also has to meet the EPA restrictions. I expect the 2027 GT to put out 500 at a minimum.

S550 PP manuals had 3.73 just like the 2024 PP manual does

The Mach 1 HP has a ton of drag lol. These results are what I expect honestly. The 24 GT is almost dead even with a 18-21 GT. I expect similar results with Dark Horse HP and Mach 1 HP. The big downer is interest rates at 7-8%

I agree 100%. I personally will be waiting. I want to see what comes in above the Dark Horse personally.

A lot of people will look at it like this: The old car is: lighter, faster, more easily modified (for now at least) and most importantly cheaper. That matters to a lot of people. There will be a mid-cycle refresh where Ford will update the S650 and I'm sure it will be given more power. Until...

S650 gained weight, comes with worse tires, (imo) isn't faster than the S550, and the price went up considerably. Combine that with high interest rates on loans and I think next summer dealers will be begging people to buy one. I want to see the Dark Horse numbers personally. If it is only .1...

Wait until someone notices the car gained weight again. They are reporting 3800+ curb weight. 550 was 3705 I believe?

I don't think they are THAT bad but they are a bit disappointing on a 60k car.
