I dont know if anyone else has been following the thread overseas on S/F, about the guy who turned an old scaley brabham into a replica of the "once only raced" 1978 Brabham fan car, with operating fan and skirts.
Well the guy gave it it's first run, theres a video up and a few blokes testified that it blew the doors of a sorted "slot it" Porsche 956.
I must admit, at first I thought the idea of a spinning fan was quite cool, but once he started talking about actually creating a ground effect I thought he was just having a wind up, but it actually appears this bloke has pulled it off. A few others who witnessed it said with the fan removed, it was a fair bit slower.
If you haven't seen it ,you have to have a look.
