Most aerodynamic locost
Usings the book chassis who has created the most aerodynamic body for a locost? Both fully enclosed and open wheeled.

Seems like the fastest 7s (Caterhams and Donkervoorts with 150+ mph top ends) have ducted nosecones, wrap-around front cycle fenders, and inboard
shocks.

i would hazard a guess that the gts 11 full body is one of the more aerodynamic fully enclosed bodies to fit easily onto a book chassis. i'd
also suggest teh st phoenix but noit sure how easily that would go on a book locost as i believe the chassis is marginally different (well its round
tube to start with iirc)

I can relate to that top picture - air battering me in the face and making it pretty much impossible to see at anything much above 50mph 
What program did you use to do those Tom?

For ST Phoenix, read Sylva Phoenix. In other words, nothing to do with locosts really.

Pete,
the models above were designed in rhino3d, meshed in a program called ice-m and solved in cfx 5.7. all part of the dissertation - so glad its over
now!

Theres a small piece in EVO this month on the Donkervoort D8 that holds the lap record at the Nurburgring Nordschleife at 7:18.01.
Has front and rear spoilers and a roof so must have immense downforce.
Possible contender?
will try an post the pic
cheers

There is no way a Donkeywart can be considered Locost.
My Phoenix is the square tube variety not the round tube race version. And although not particulaly practical you could fit the body on a book
chassis with a few mods. I consider mine to be more akin to a locost than a Donkeywart or Cateringvan.
As far as aerodynamics, I dont know how fast mine will go as I hit the limiter in top at c.130mph. There are a couple of genuine 150mph+ Fisher
Furies about which have quite alot less power than the 150mph Cateringvans which suggests better Aeros.

18 inch wide front end, low raked and split screen or brooklands(have not decided yet), and a smoothed out ass end and inboard shockers, may help
mine out a bit.

Does anyone know the drag coefficient of a locost with the windshield ?

I've used 0.67 in some calculations I did before, I think I got that by doing a search on google. I'm not sure if that includes a
windscreen or not but it is for a Caterham and they generally have screens.
Hope that helps

this discussion is pretty pointless though, (apart from the dissertation obviously!!) as in any guise the locost is useless aerodynamically!!!!

Very true as minor changes to the locost for aerodynamics(unless your trying to get a bit better on a long straight away) is pretty much useless.
Just fun banter. Just as a locost type car really serves no usefull purpose execpt to be be fun. As I have told my wife - there is no valid reason
what so ever to build this car- other than I want to.

areodynamics and se7en in the same sentence - there something you dont see every day!!!! Chalk and cheese springs to mind.
