Throttle Body Elbow

11/20 Update

This week:

• Finished reluctor wheel mount 
• Finished crank sensor mount.
• Continued with wiring harness modification.
• PCM back from tuner
• Finished throttle body elbow

Next week:

• Finish wiring harness.
• Plumbing for fuel lines
• Start install on test car

• The group met this past weekend to work on installing spark plug boots onto the wires.

• Both PCM and Coil mounts were installed under the hood of the car.

Mock Up Engine/Wire Harness Modification

11/6 Update

This Week:

• Drawings/models for major parts
• New Gantt Chart for November/December
• Mock up engine for test fitting parts

Next Week:

• Start building parts (PCM bracket, coil brackets)
• Finalize models for 3d printing (throttle body elbow, distributor cap)
• Wiring harness routing on mock up engine
• Test fitting manufactured parts

November Gantt Chart

10/30 Update

This Week:

• Throttle Body Elbow DOE
• Coil Bracket and misc. small parts design
• Finalizing dimensions

Next Week:

• Final drawings for most to all parts
• New Gantt chart for November
• Scheduling for manufacture

Throttle Body Intake DOE

Problem Statement

• A DOE (Design of Experiment) was done on the throttle body intake.  
• Three different designs were used as initial runs (Low Intake Elbow, High Flow Intake Elbow, Box Intake Elbow)
• Two variables were altered for this experiment; throttle body flange angle and spline gap.

• The max velocity at the outtake was used as the main result in deciding which design proved to be best.

Results

The top three designs were selected...

3847_splinegap_1

3848_splinegap_2

3847

Conclusion

• Throttle body flange angle and spline gap were the two main variables that could alter the max velocity at the exit.  
• Of the two, changing the spline gap yielded the highest max velocity.  
• Further design will be done when final measurements are taken at throttle body.
