This guy isn't playing around....
During a test session that tortured and killed the truck’s Turbo 400 transmission, Garrett had laid down a crazy-fast 7.70 ET at 186.9 mph in the quarter mile. Using a power/speed calculator, Garrett figures that the engine must be making at least 1,920 hp to go that fast—but considering the pass was conservative (to save the trans) and he had to lift off the throttle momentarily at half track (to regain control), he believes it is actually making well over 2,000 hp.
Since the Turbo 400 had become a limiting factor, Garrett has since replaced it with an air-shifted, three-speed B&J planetary-type transmission with an AFT “two-and-a-half disc” 11-inch clutch. This set up has brought with it a whole new set of challenges, not the least of which is launching and Clutch management. However, once the set-up is dialed in, he believes the truck has the potential to go low 7 or high 6-second quarter mile ET’s, solidifying his title of World’s Fastest Street-Legal Truck and making him a legitimate threat in Pro Street—a class dominated by state-of-the-art race cars.
