I was basically given a 20.5 hp chem-Tex panther unit. I was allittle wery about putting it to use as someone who has only ever used CDs 4.8s and titan units I wasn’t sure how it would compare. After teaching one of my techs to do the belts and oil changes on it and him running it for a month he has let me know that he feels it preformed just as well as the titan 575 and cds’ that we run. With better heat then the cds. Great value for a truck mount will be interested how it holds up in the long term and will be looking into using these for future van builds and
