Michael Waltrip Racing Uses Jet Edge Waterjet to Manufacture Racecar Parts MWR Increases Productivity, Cuts Costs with 90,000 PSI Jet Edge! Michael Waltrip Racing (MWR) reports that it has experienced dramatic water jet cutting productivity gains and cost reductions since powering its Jet Edge waterjet system with Jet Edge's 100hp 90,000 psi X-Stream waterjet intensifier pump in January. "We've been seeing, across the board, a 35% improvement in cutting speed, plus we are using about 25% less garnet abrasive, and we have reduced our costs by 30%," said Nick Hughes, MWR's technical director. "As an example, our spindles, which are one of our more complicated steering parts and cut from 2" 4140 steel, used to take 50-55 minutes to cut at 60,000 psi. Now we are cutting them in 30-44 min
