Project Steps
• Installation Check Out• Compressor – air flow rate• Radiator – sizing of heat exchanger• Intercooler – sizing• Selection of components• Next Steps
– Instrumentation Locations– Power Increase – based on airflow– Heat Exchanger Area

Turbocharger installed in engine
• Turbocharger fits where the old one did
• Brackets and oil lines fit• Turbocharger runs with engine

Turbo Compressor
• Airflow out of the compressor, mass flow• CFM = airflow rate• CID = cubic inch displacement = 395• RPM = revolutions per minute = 2000• VE = volumetric efficiency = 80%
• Correcting for a boost pressure of 18psi:

Intercooler Calculations
• Same as radiator• Different flow rates and temps

Heat Exchanger Selections
• Unknown value for U• Unknown value for A• Discussion with manufacturer• Feasibility:
– Cost– Size (dimensions)

Next Steps
• Instrumentation Locations– Inlets/outlets of heat exchangers
• Increased Engine Power– Based on airflow
• Validate Heat Exchanger Selections– Includes estimate on fin area based on actual
measurements– Fit checks– Tube routing
