Racers and engineers,

Let’s hear thoughts and experiences in ref to race cars that are perceived to be non-aerodynamic compared to race cars considered to be aerodynamic. In addition, let’s talk about race car weight.


*The 1927 style full fendered roadsters carry the reputation of having high wind resistance, high drag, thus considered aerodynamically poor. However, they are usually light in weight

*The 3rd generation Firebird is considered to be aerodynamically sleek, thus having lower drag or lower resistance. But these cars weigh 800 – 1000 more than a Roadster [Of course they are many other bodies to consider, the two listed above are for examples]

Also, lighter weight cars are “perceived” to be better than heavy weigh cars

The feedback wanted is real examples of successful, winning, consistent race cars and how that package might be considered aerodynamically and weight.

Let’s hear your experiences with 1/8 mile racing, do aerodynamically good packages show any real world advantage over packages that are not as sleek?

Just throwing this idea out for brainstorming.

IMHO a light car would have an advantage over an aerodynamic one for 1/8 mile racing. My reasoning is the light car is going to move quicker than an aerodynamic one and the wind resistance doesn't factor into it until it gains speed and that increases as you get down track. The weight advantage factors in just as soon as you launch. If you're choosing between a roadster and a firebird for 1/8 mile racing the roadster will be way quicker than the firebird with the same power, that is if the roadster is really 800+ lbs. lighter.

with all the improvements made in the roadster bodies used in Comp. the areo becomes less of a consideration. Look at all the louvers and placement in the pictures I sent you of my car. There are more that could have been added, but I opted to use a full belly pan.
The belly pan helps the side/running board louvers work... Moving high pressure air to low pressure areas reduces drag.
