Kart body aero dynamics

[cking]

Running on a full 1/4 mile track and noticed that when getting behind other karts there is a slight draft effect.
Is there a best body for the big tracks?
Is there a style that dirties the air up better behind you?

My belief is the human is the biggest factor not the body .
Of course the body has an effect .
As far as dirty air that may be where the rear floor pan comes in play .

After many years of street racing, drafting is a big factor in a race. If you lose draft with the leaders, you'll go backwards unless you can run faster than them by yourself. Most of the races, you need a drafting partner. Body shape and drivers fairing does come into play.

In about 1991, Buller experimented with different nose shapes for Daytona speed week. They tried to make their own drafting partner.
A mini sprint tail cone was pressed into service as a nose. The result was created a huge hole in the air. Everyone wanted to be their drafting partner.

This was seen at a few street races, while they worked out the kinks.
It was said the draft pocket could be felt 10 kart lengths behind.

The Chavous, LA Body (Pink Magic), and the JKB X-act Fit bodies seem to be the most sleek on the big tracks at the moment.

The only secret I know to speed is...punch a hole in the air and drive through it. Dont wedge the air.

The slipstream 2 from Chavous and the Haskins body draft real well from my experience
