6/15/04:  Our latest video is of the Thunder in Muncie 2004 sled pull.  During this pull we are running twin turbos hx40/18 + Holset HT60 @ 73 psi of boost.  Listen for the blow off valves opening up to keep the boost at a respectable level.  The driver powerbraked until 10 psi of boost and then released the brake.  No nitrous, no propane, no water/methanol.  Just Diesel.  This is approximately 480 HP! 

 

6/6/02:  This is a sled pull in Muncie, Indiana in 2002.  Add a large single turbo (H2E) to a tight torque converter and this is what you get.  Lots of smoke and lag until the rpms come up.  Notice how the engine never bogs at the finish.

6/28/03: This video is of a Clash of the Titans race in June of 2003 at Houston Raceway Park. We use competitive events like this for R&D and product testing.  We ran a set of twin turbos that were quick spooling, but too small to withstand the 200+ HP shot of nitrous.  The turbos exploded at the 1/8 mile which put us in coast mode for the rest of the track (5+ seconds) yet we still ran a 13.20 @ 80 mph. (left lane)

6/9/03: This video is of a sled pull in Muncie, Indiana in July of '03.  This video shows our test truck pulling at 95 psi of turbo boost and 4300 rpm.  You can hear the nitrous shot come in and see the truck spin sideways from the gain in power.  Once again, a perfectly good set of twin turbos explode from the torture test.  The small turbo was a Relentless diesel hybrid turbo custom built for lightning quick spoolup.  The truck was a blast to drive on the street, but the turbo was no match for the 200+ nitrous shot.  During this pull, the pinion gear also broke.  10 of the 13 teeth were broken!!!
