Dark Horse hp vs GT hp

Where does the Dark Horse pickup the additional crank horsepower ?

That‘s a darn good question, I’ve wondered the same thing. Hopefully someone here actually knows.

486 in the GT seemed good but 500 is a nice round number. Truth is I’d about bet it’d be hard to tell the difference.

Tune. palm beach managed to pull the data and compared it https://www.google.com/search?q=24+...d-att-us-rvc3&sourceid=chrome-mobile&ie=UTF-8

At the very peak in the rpm band… the tuning begins closing the GT throttle bodies a few ms before the DH… that’s it.

if tuning were unlocked there would be zero HP difference… it’s literally being handicapped at high rpm by the tune.

@swamprat7953 ..... the usual changes are crankshaft (blueprinted/balanced) cams (thanks for the note @robvas) more aggressive, more durable rods, timing and RPM. These the DH has over the GT. That is why I would feel comfortable supercharging a DH but not so much a GT as the GTs rods (IMO) are a weaker link in the upgrade chain.

 

[Q6543]

@MAT1955 pistons are the issue and set the limit for both… not rods.

9/10 too much boost, too tight gap in one of the factory rings… they kiss and send a chunk of ringland up.

 

[Mr Hyde]

Only difference is the forged rods from the predator engine. Unless you can compare dimensions to see if they are longer or just more durable. Ring gap will kill an engine quick.

Gen 2/3/4 Coyotes take plenty of boost....

More agressive crankshaft? Did you mean cams?

 

[Q6543]

The cams were supposedly from a harder material, but no difference as far as lift, duration etc.

 

[MAT1955]

@Q6543 .... upgraded rods are must for most higher performance engines. Less robust rods are a failure point.

Do you guys think that’s why we can’t tune the vehicles? So they had a selling point on the dark horse?

More than likely ford is trying to cash in on the tune/accessory supercharger market. Most computers are locked these days whole right to repair thing that manufacturers hate. Theres two ways around a locked ecu, crack the coding or physical bypass and removal. The 2015 and up dodge/jeep modules have to be physically bypassed to tune or you can plug in a module directly to the ecm that sends and reads the data then mods the outbound data sent to the engine and feeds the ecu stock data basically knocking it out of the engine loop but running the rest of the electronics.

No.

You can't tell the difference. I drove both back to back. I was intent on getting the DH but after driving both said screw it and got the GT.
