How close to the chased car should you place your car for max slip streaming effect? As close as you dare? An early braker och a missed shift would seem to make the technique a bit risky. Also: how far sideways of the forward car can you place your car? If the is a significan slipstream effect either side of the forward car placing your cara bit to the side gives an escape route in case of sudden speed changes.



No experience of this and doing an endurance race Saturday so a bit curious to try it.

Looks like the short answer is 1/2 to one car length behind the leader...the very long answer is here>>>

If you want a CFD model of drafting strategies for a 968 I could probably have one of our engineers whip one up for about $40k

lol - you can feel it when you're there - go out with a buddy and practice - do it on straight road and at a set speed - then you can watch the gauges and feel the car changes



of course, please be careful and obey all laws

T,



The closest the better obviously, but one mostly does this in an attempt to pass while outbraking the guy in front. In that case I always pull out to whichever side I will take into the turn before the braking zone. If I know the guy will defend hard, I wait until just before the braking zone and pull out to the outside. If he/she is not going to fight hard, then i pull out a bit earlier to the inside so that he knows where zI am going and that I am going to go for it. At that juncture it should be too late for him to defend (if he knows what he is doing) as I would hope you will have some overlap by then.





Which brings me to my main point: I find it has a LOT to do with who the racer in front is. If I know the person and know he is a predictable and a consistent good racer, I am confortable with much closer racing (drafting, passing, etc). If I dont, I act accordingly and keep a reasonable distance...





Hopefully you have set up the pass well before, from at least the previous turn, so that you are carrying more speed out of the turn and down the straight. This will allow you to not really really spend a lot of time behind him given that you will be passing at the end of the straight and will at least have a nose in by the time you get to the braking zone...





Have fun!

to practice, one thing i forgot to mention is that since the 2 of you will travel faster than 1 when you are sharing the wind, you have to set the lead car on cruise control so it will maintain speed better when you pull out of the draft, and the lead car wants to slow down - otherwise you get into a very difficult to manage situation where both cars are changing speed too much for a good practice
