build diary September 27, 2005: The Se7ens are coming! Some scrambling around yesterday and the hood is now punched with louvres! I had to change the layout a bit because the spacing between the louvres was different than I had assumed. These are hot rod louvres and they're bigger than the ones used by the Seven makers. Still, the layout looks good - except for one small detail. It turns out that hot rods put their louvres facing forwards (why?). Those who know something about aerodynamics put them facing backwards. Well, these were punched by a hot rodder so they're backwards. I just never thought to specify even though we were laughing about how it was important to get them the correct way around. The problem that both of use considered the "correct way" to be different. This will work fine at a walking pace, but at speed it'll actually make the airflow worse than before. I'm going to be very embarassed showing up amongst the Se7ens this afternoon with a backwards hood. Kent, the guy who did the work, has bought a new piece of aluminum so I can fabricate another hood. I'll have to work fast, I'd like to have the proper setup for the race this weekend and definitely for the high-speed trackday at Aspen on the 15th. I also have to change the brakes on two cars. It's going to be a long week. Oh well, if it was easy everyone would do it... entry 1021 of 1439 |
