Did Project White Dragon Fail?

Since day one, we always kept in mind that people will only want more power. In anticipation, we chose to use 3" MAF piping in all of our turbo kits and the GTM Stage 2 Supercharger Kit. Doing that gives us more headroom when it comes to MAF Voltage. It's a mechanical calibration that allows us to get the factory MAF to read more airflow. Even at 600whp, the MAF voltage is getting up to 4.9 to 4.95 Volts. While this is still below the 5 Volt limit, it does not give us any headroom to compensate for changing atmospheric conditions (such as a cold morning). The next step was to find an aftermarket MAF sensor that can replace the factory Nissan unit with the same physical dimensions and connector. Of course, that was the easy part. The challenging part is to produce a good calibration that contains a linear MAF curve so we can get the best resolution and still plenty of headroom for more horsepower while retaining factory drivability. This development translates into having a 1000hp car that starts up every time and can be driven normally on the street.
Ultimately, this has greatly expanded the capabilities of the factory ECU to the level of performance commonly relegated to a standalone EMS. While some standalone EMS options may have some additional features that set it apart, we've really narrowed the gap here.
To close the gap altogether, we are working on developing a system that will enable us to retard ignition timing in response to knock as well as boost cut. Once that is developed, there will be no reason for a standalone EMS in this platform.
Here is a dyno graph and a cipher screenshot showing only 4.5 volts maf reading @ 886 RWHP witch is equivalent to roughly about 1036 BHP .
Will be posting up a video of the car on dyno shortly .

~1000BHP.
Getting close to the 1000who goal.

Interesting that you say that considering you gave a $hit when you thought they were goin to fail. Not trying to start anything but in the other thread that got locked, exactly what I predicted happen. That was when they came out with the results people were just going to not care anymore and find something else to ***** about with the car. "smoke and mirrors" LOL

Just like that story about the girl that cried wolf...
Hype
Hype
No one is going to care...they should of keep a lid on it...
Still would love to see this power hit the streets....

It is still more hype and smoke & mirrors. After all this time, it took this long for them to post proof of only 886whp, even though the car owner claimed prior that the car already made 1000whp. Only 886whp with a VQ37VHR bored & stroked to 4.5L and twin GT35R turbos and we're supposed to be impressed? LMAO! For comparison, another shop made 906whp with a stock displacement VQ35DE with stock sleeves and stock intake manifold with a plenum with a spacer. Also, Sound Performance made over 1200whp with a sleeved stock displacement VQ35DE. And meatbag just made 844whp with a stock displacement VQ35DE motor and 20G turbos tuned on an FCon VPro.
I guess the GTM fanboys are easily impressed even when a GTM VQ37 project falls short of stated goals & boasts, as well as significantly short of old 3.5L VQ35DE benchmarks.

Oh my god I didn't think it could get any worse, but those wheels take the cake 
the guy that owns this train wreck is a fail artist.
Some people were never meant to try different things. This car is a case in point.
