Veryon Slayer?

It seems that the guys at AMS tuning out of West Chicago, Illinois, have devised the means to outperform the world heavyweight champ.  The AMS GT-R has been recorded pulling away from the Bugatti Veyron in the 1/4 mile drag race.  The performance numbers are staggering for a twin-turbo V6, nearly identical specs as the Veyron's W16 quad-turbo monster.  The AMS "Alpha 9" is a $21,999.00 aftermarket kit for the Nissan GT-R.  That being said, the grand total for the package including the GT-R price is between $100,000 and $120,000 (depending on the year of GT-R, 80-90k).  SO...for the price of a Porsche 911 Turbo, you could have transformed the GT-R into a world beater. 
The GT-R was originally created to go head to head with the Porsche Turbo and early claims were that it was faster around the Nurburgring.  Also it costs 30-40k less, and therefore, the better performance value.  Now it is doing it again, only this time going against the Veyron, a millon dollar+ car, and top speed holder (SS model).
That's the one drawback, it seems.  All the money savings does become evident when it comes to outright top speed.  Of course a W16 quad-turbo will have a higher top end than a V6 twin-turbo any day of the the week.  The AMS Alpha 9 will pull 141MPH in the 1/4 mile with 9 second times, and blasts through the standing mile at 205MPH. 
As far as a usable performance variable, we all know that much higher than 200MPH is nearly unobtainable in the real world, yet the GT-R remains composed enough to drive everyday, much like the Veryon.
Yes, the Veyron SS is faster and lighter still, but will set you back a cool 2 million.  For that money you could have a whole fleet of awesome tuners which are still faster than 99.999% of the cars on the road.
