Why you ask? Because to go 143 in the 1/4 mile on the 991 Turbo and Turbo S platform will require fuel system upgrades. What fuel system upgrades are they running? This is clearly necessary beyond the bolt on level which the factory fuel system does support.
Also, a trap speed of 143 miles per hour is much more than 650 horsepower. Even at the wheels. Where is a dyno for this car?
This network yet again can not explain Middle Eastern 1/4 mile anomalies or modifications. They say bolt on but do you really think this is the stock DME? Ekanooracing and ESMotor can claim to throw as much money as they want at a Porsche 911 Turbo S but you are not getting a 143 miles per hour pass out of it with bolt ons.
Something just is not adding up unless you believe this:
Just to clarify the claims in the thread.
The car has stock engine, never touched, and believe or not, it has completely stock fueling system.
Its running our exhaust, headers, water/meth injection kit and our ecu module.
It also has our "specific" alignment settings for better traction on the launch.
Upgraded VTG's and upgraded intercoolers; i'm testing them on my personal car, i will release more information about them soon. "
There is a video below but who knows if it is actually a 991 Turbo S that is running as you can not tell from the video. We have no explanation.
