{"product_id":"eaton-m90-supercharger-kit","title":"Eaton M90 Supercharger Kit","description":"The Boosted Technologies supercharger kit is engineered for 1987-1992 Jeep Comanche 4.0L engines, offering a safe, reliable, and affordable power increase. This kit features a modified GM 3.8L Eaton M90 supercharger, providing instant boost with no lag and 4-7 pounds of boost on the stock 4.0L engine. Installation is designed to be straightforward, typically taking 4-6 hours, and requires no hood modification.\n\nThe supercharger system integrates a custom intake manifold and retains A\/C functionality without relocating any engine components. It is compatible with various aftermarket upgrades, including larger throttle bodies (62-70mm), cat-back exhaust systems, higher-flow injectors (703\/784), roller rockers, camshafts, and ported cylinder heads. For 'stroker' engines 4.5L and larger, the kit is adaptable, though expect slightly lower boost levels with a power increase of +20-25%.\n\nFueling is managed by a 60lbs\/hr 7th injector, which supplies additional fuel under boost and contributes to liquid intercooling. The included Split Second FTC (Fuel Timing Control) module is fully laptop programmable and comes with a pre-loaded base tune. It controls boost timing retard and the auxiliary 7th injector. For remote custom tuning, the FTC requires at least one Data Acquisition channel and an AFR gauge.\n\nInstallation prerequisites include sourcing a newer-style 3-bolt power-steering pump, throttle body, and a 2-port fuel rail from early 1990s 4.0L Jeep models. The system operates with completely stock EFI settings and function when not in boost. Note that boost levels are altitude dependent, and higher boost pulleys can be purchased separately.","brand":"Boosted","offers":[{"title":"Default Title","offer_id":52687222604088,"sku":"BTM90FTC121BMJ40SM","price":3545.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660188779.jpg?v=1784881547","url":"https:\/\/store.motormia.co\/products\/eaton-m90-supercharger-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
