1K HP Club for the Lethal Performance DarkHorse!!

[JakeLethal]

Our 2024 Mustang Dark Horse hit the dyno at Area 51 Motorsports, laying down 1049.5 rwhp and 751.4 ft-lbs on E85.​

• Lethal Performance Edition Whipple Gen 6 3.0L supercharger
• 3.50" Griptec pulley
• 10-rib kit w/ ATI 20% balancer
• 1300lb Injector Dynamics injectors
• KPM 1500hp Fuel System
• Custom E85 tune from Shoemaker Performance
• 20.7 psi peak boost
• Stock headers, stock motor

Next goal: 8-second passes (when Florida weather cooperates)

All stock engine internals . . . cool!

Ok, the video starts with filling up at the pump. Was the dyno run on E85 from the pump at a local filling station or specially purchased VMP or other provider? EDIT: Further into the video the question is answered, "straight from the pump." Neat stuff.


and "stock headers"

Stock headers is CRAAAZY work…. Couldn’t be me.

I didn't know either and was very surprised myself lol. She making some JAM!

Are the catalytic converters still there or gone?

Gutted ;)

impressive results! 20.7psi of boost on a 12:1 compression ratio engine is just nuts. and it handles it all pretty well for stock internals and exhaust manifolds, but i really wonder how long this engine will last at that power level. also, did i read that right in the video that you guys revved it out to just shy of 8500RPM?

You already know this, but maybe need to remember, the Dark Horse engine does not have the same rods and crankshaft as the regular GT.

Too much horsepower is almost enough

Too much horsepower is almost enough

As long as you have the torque to back it

 

[Wiley Marmot]

No such thing as too much HP to get groceries with. Time is money!

 

[LouG]

As long as you have the torque to back it

Torque x RPM divided by 5252.

 

[Zig]

Torque x RPM divided by 5252.

That is correct. But if it falls off precipitately after the cross over it’s akin to driving in overdrive.

never too much torque? But i’ll agree to agree. horsepower is a byproduct of torque over time.

Looking at the posted graph, it looks like maybe they got on the throttle hard above 4000 rpm, so the numbers lower are not the real output.

I would guess that a Whipple supercharged engine with a 3.5 pulley would have plenty of torque down at 3500 rpm if the throttle were mashed to the floor.

Not a lot of reason to floor it below that or dyno it at that low of RPM (and some dynos have problems measuring that low), so most pulls start at higher rpm
