{"product_id":"stealth-mach-1-vgt-turbocharger","title":"Stealth Mach 1 VGT Turbocharger","description":"The Calibrated Power Stealth Mach 1 turbocharger is a direct, bolt-on VGT upgrade for 2017-2023 L5P Duramax engines, and is also compatible with 2019+ L5D models. Engineered for a balance of performance and drivability, it supports up to 700 rear wheel horsepower in competition applications with extensive supporting modifications, and up to 650 RWHP with emissions-compliant tuning and basic supporting mods.\n\nKey features include a custom billet 64mm 11-blade compressor wheel for a wide efficiency range and reduced surge risk, and a 70.4mm 9-blade nickel alloy turbine wheel for a distinctive exhaust note and improved high-load efficiency through Calibrated Power's proprietary High Flow Vane (HFV) technology. This design results in lower drive pressures, better Exhaust Gas Temperature (EGT) control, and a fully functional exhaust brake.\n\nThis turbocharger provides 74 lbs\/min of airflow, an increase from the stock 60 lbs\/min, and offers quick spool-up for usable horsepower. The unit is a brand-new assembly with no core charges required. However, the actuator is sold separately, and custom tuning is strongly recommended to optimize performance and emissions compliance.","brand":"Calibrated","offers":[{"title":"Default Title","offer_id":52687332409656,"sku":"DM1JK1070203000","price":3100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661175042.webp?v=1784882777","url":"https:\/\/store.motormia.co\/products\/stealth-mach-1-vgt-turbocharger","provider":"MOTORMIA","version":"1.0","type":"link"}
