Question for the Engineers - 2003-04 Mach 1 Registry Owners Club

Fastang70 · 04-21-2007, 12:50 PM

I am in school working on a Mechanical Engineering degree. I am taking a lab right now. Currently we are studying drag force. Well thought it would be a cool idea to put my model of my 2004 Mach in the wind tunnel.

I need to see if any of you guys know the drag force coefficient for a 2003-04 Mustang Mach? I need the actual number so I can compare it to my experimental data.

Thanks,

Brad

Listed in the "Tech Specs" here on the site: (http://www.mach1registry.com/Specs/Specs.htm)

Aerodynamics Coefficient of Drag (Cd) 0.36

Let us know what you find...

Hopefully the coefficiant is not like a weld, 1.0.....

Well, I am done with the wind tunnel testing on the model. We had a significant error, but our results yielded around 0.32 Coefficient of Drag, that was with a 150 gram drag force on the model. As we increase the wind speed the drag force increase. So I concluded that the 0.36 is indeed accurate. Note: the sting is there just in case the fishing line decides to break. The model tangled in the fan would not have been a good thing.

thats pretty cool man.

Yep, the Cd is between 0.350 - 0.360 depending on the specific model (spoilers, etc.). Since you're interested in becoming an ME, there is actually very nice dragracing software available that lets you "predict" quarter mile performance very accurately (if you know all the parameter values). This has definitely helped me at the track, since I can see the effect of weather, weight and traction, and play lots of what-if games to look for gains. Check out performance trends, I was pretty skeptical at first, but it really does a nice job. As you may already know, the hard part is making sure all the parameters in your model are correct.
