Holset HE431VE series. Application: Volvo D11 \/ Mack MP7 HE431VE. Variable geometry turbochargers use a ring of movable vanes in the turbine housing to change effective turbine area on the fly, giving fast low-rpm boost response, controlled boost at high rpm and the exhaust brake function the engine relies on. Worn vanes, a sticking unison ring or a failed actuator show up as low power, excessive drive pressure, poor exhaust brake performance and VGT position fault codes. Holset has been the original-equipment turbocharger supplier to Cummins and other heavy-duty diesel manufacturers since the 1950s, and genuine Holset units are built to the same drawing, materials and balance specification as the turbocharger the engine left the factory with. Fitting a genuine Holset charger restores factory boost response, drive pressure and exhaust temperature control without the fitment guesswork that comes with will-fit replacements.","brand":"Holset","offers":[{"title":"Default Title","offer_id":47134036492461,"sku":"HL-4031002H","price":4357.4,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.dfispdx.com\/products\/holset-new-turbocharger-volvo-d11-mack-mp7-he431ve","provider":"Diesel Fuel Injection Service","version":"1.0","type":"link"}
