Engine output depends upon the amount of the airfuel mixture ignited per unit of time. Therefore, to increase engine output, the most effective method is to send a greater amount of air-fuel mixture into the cylinder.\n\nIn other words, by installing a special turbocharger and providing more air-fuel mixture than usual, engine output can be increased by increasing the average combustion pressure without increasing the engine speed.\n\nSuperchargers are either turbocharger type (using exhaust gas to turn the turbine) or supercharger type (using the engine crankshaft etc., to mechanically the pump, etc). For the Supra 7M-GTE engine, the turbocharger type has been adopted.","image":"https://tsrm.sasquatchvc.com/images/mk3/TC/TC_002.png","url":"https://tsrm.sasquatchvc.com/mk3/tsrm/TC/2","prev":{"page":1,"url":"https://tsrm.sasquatchvc.com/mk3/tsrm/TC/1","api":"https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/TC/1"},"next":{"page":3,"url":"https://tsrm.sasquatchvc.com/mk3/tsrm/TC/3","api":"https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/TC/3"},"section_url":"https://tsrm.sasquatchvc.com/mk3/tsrm/TC","section_api_pages":["https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/TC/1","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/TC/2","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/TC/3","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/TC/4","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/TC/5","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/TC/6","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/TC/7","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/TC/8","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/TC/9","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/TC/10","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/TC/11","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/TC/12","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/TC/13","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/TC/14","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/TC/15","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/TC/16","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/TC/17","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/TC/18"],"note":"OCR transcript of a scanned Toyota factory manual page; verify critical values (torque specs, part numbers) against the image."}
