Cd estimate for open-wheel dragster?

[kennybobby]

i was searching for an expected drag coeff for the typical open-wheeled style dragster such as shown here, has anyone seen measured or calculated Cd for this? Body panels would obviously be added, this is just the rolling chassis.

This seems to focus on the tires and wing, rather than overall drag:

A comparison between student's work with no numeric result:

You'd be looking in the Cd 0.9 range.If you put wings on it,she'd go over Cd 1.0.
In 1987,the Arrivet Brothers,of Southern California were experimenting with a fully-enclosed,streamlined NHRA Top-Fuel dragster.She measured Cd 0.20 @ zero-degrees yaw,and Cd 0.18 @ 12-degrees yaw.
