This past weekend was incredible for diesel performance. The NHRDA (National Hot Rod Diesel Association) held their annual Diesels On The Mountain event presented by BD Diesel Performance at Bandimere Speedway in Morrison, Colorado. The track is 5,800 feet above sea level. But you might be asking, “What does that mean”?

At sea level, the static air pressure is roughly 14.7 psi. At 5,800 feet, static air pressure is roughly 11.85 psi. That is almost three psi less. Air density drops about 14 percent as well. So, not only is there less pressure static, but the density of the air up there is much less. This hurts performance
Generally, when an air-breathing engine is exposed to these conditions, the engine produces less power. The lesser power results in slower speeds. But for some reason, that wasn’t what was happening. There were actually multiple records set during the weekend.
The video above shows Wade Minter in this triple turbocharged Duramax lined up against Rob Coddens (Idaho Rob) in the quarter-finals of the NHRDA Super Street class. These are two very good drivers with extremely powerful and fast trucks. They are regularly the last men standing at the end of an event and both were running well all weekend.
Coddens won with a holeshot against Minter, both racers ended up breaking the 150 mph mark during the pass. Coddens took the win with a 9.36-second run at 152.37 m.p.h. The 9.36 run backed up his earlier run of 9.47, giving him the official ET record. His next pass backed up the M.P.H. record.
Not only did Coddens take home two new records, but he, also, took home the win for Adrenaline Truck Performance (ATP). Good job guys! The way diesel trucks are progressing, we can’t wait to see what the next NHRDA event brings.
