Problem Statement
• The Product: Methanol Injection Throttle Body
• The Need: Increased Engine Performance for the GT Motor-Sports Formula SAE Car

What Does A Throttle Body Do?
Current throttle body used by GT Motor-Sports
![Page 5: Doug Matthews, Vuchuong Do, Chris Dayton, Theral Mackey, Monica Franz, Brian Smith.](https://reader033.fdocuments.us/reader033/viewer/2022051404/5a4d1aec7f8b9ab05997ba04/html5/thumbnails/5.jpg)
What Are We Doing Differently?
• Place a fuel injector before the throttle body – Cooler, denser air enters the engine – Increased engine performance
• Total redesign of the throttle body – More efficient design
• Incorporate venturi into a throttle body housing – A totally self contained design
![Page 6: Doug Matthews, Vuchuong Do, Chris Dayton, Theral Mackey, Monica Franz, Brian Smith.](https://reader033.fdocuments.us/reader033/viewer/2022051404/5a4d1aec7f8b9ab05997ba04/html5/thumbnails/6.jpg)
Engineering Analysis• Materials Used
– PET / Throttle Body – Aluminum – Pre-Preg Carbon Fiber
• Air Filter Sizing • Throttle Body Sizing • Throttle Body Barrel Sizing • Bearing/Screw Specifications • Throttle Body Barrel Opening Angle vs. Percentage of
Open Area • Total Weight

Our Solution
Complete redesign consisting of a throttle body assembly and a housing

Throttle Body Valve
Full Throttle Half Throttle
IdleThe valve is never completely
closed

Throttle Body Valve
There are several components of the throttle body valve.
There has since been a 1.5 inch hole drilled in the sleeve and barrel

Throttle Body Assembly
In addition to the actual throttle body valve, the throttle body assembly has a few more components
![Page 11: Doug Matthews, Vuchuong Do, Chris Dayton, Theral Mackey, Monica Franz, Brian Smith.](https://reader033.fdocuments.us/reader033/viewer/2022051404/5a4d1aec7f8b9ab05997ba04/html5/thumbnails/11.jpg)
Housing
The housing was constructed by laying up pre-preg carbon fiber onto the mandrel
![Page 12: Doug Matthews, Vuchuong Do, Chris Dayton, Theral Mackey, Monica Franz, Brian Smith.](https://reader033.fdocuments.us/reader033/viewer/2022051404/5a4d1aec7f8b9ab05997ba04/html5/thumbnails/12.jpg)
Housing
The housing material was vacuum bagged. The mandrel can be disassembled to remove the finished housing
![Page 13: Doug Matthews, Vuchuong Do, Chris Dayton, Theral Mackey, Monica Franz, Brian Smith.](https://reader033.fdocuments.us/reader033/viewer/2022051404/5a4d1aec7f8b9ab05997ba04/html5/thumbnails/13.jpg)
Finished Housing
The housing and the throttle body valve were combined to produce the finished product.

The Finished Product
Total Weight 2 lbs. 8 oz. Total weight without peripheral systems (Air filter, Injector, and TPS): 1 lb 13.3 oz.Weight of Carbon Fiber Housing: 5.32 oz

Future Work
• Testing and Tweaking• Reduce Weight• Integration with a naturally aspirated turbo charger
GT Motor-Sports Dynamometer
