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.

Weekend Junkyard Run



This weekend the group went out for a junkyard run.  We ended up going to three different junkyards looking for cooling fans and an adequate fuse box.
