Damdy-Cash Posted August 31, 2010 Share Posted August 31, 2010 I have a copy of the 2001 Autocar articel "Tunnel Vision" about this. May it's the same as the discussed one. I have a look as sonn he post the link and if not I will send it over to myothercarsa2cv for sharing it as well. cheers Volker Link to comment Share on other sites More sharing options...
k.russell Posted August 31, 2010 Share Posted August 31, 2010 Linsey Mercer had some mods done to his SV R300+ that were along these lines, it did make improvements. here flat floor sideskirts and defuser etc. all in aluminium. sideskirts did make getting off the trailer a little tricky. I feel the re- rooting of the exhaust through the passenger area could give a little gain if the car was going to be a full on racer with aero, especially if an a ali tonneau over the passenger area would make this area unused.

Mike Biddle Posted September 1, 2010 Share Posted September 1, 2010 My car has a diffuser, inboard front suspension, full floorpan (sump does not protrude below chassis), 5" headlamps, vents in cycle wings and aeroscreen. At 162 MPH on the main runway at Brize Norton it felt secure and planted, not at all light on the steering. Link to comment Share on other sites More sharing options...
Z3MCJez Posted September 1, 2010 Share Posted September 1, 2010 Thanks for the link MOCA2CV. Interested to read that at 100mph the roof and doors are worth 10hp. Do you know how much of this was from the doors (that I am allowed to race with) and how much was from the roof (that I am not). As neither increase the swept area, I presume that it's of net benefit to run the extra weight. Also, how would a half-door compare to a full-door?

CageyH Posted September 1, 2010 Share Posted September 1, 2010 Doesn't the very nature of a 7, with an undertray make it act a bit like an aircraft wing? If the air can pass quicker underneath the car, it can't be good without something else to counteract this? Only dead fish go with the flow....!

ECR Posted September 1, 2010 Share Posted September 1, 2010 I had an interesting illustration of lift in my car last time I was at the ring. I had wedged my baseball cap firmly down behind the passenger seat but it was easily sucked from the car when I was running flat out on the straight. That experience also reminded me how much my helmet was lifting against the strap at the same speed. The lift must be pretty large .... Link to comment Share on other sites More sharing options...
CageyH Posted September 1, 2010 Share Posted September 1, 2010 Lift or turbulent air? Only dead fish go with the flow....! Link to comment Share on other sites More sharing options...
ECR Posted September 1, 2010 Share Posted September 1, 2010 Lift I think.... Link to comment Share on other sites More sharing options...
CageyH Posted September 1, 2010 Share Posted September 1, 2010 I have had things float up off the floor when making progress. I was never sure if this was due to turbulent air, or reduced air pressure above the object. Only dead fish go with the flow....! Link to comment Share on other sites More sharing options...
MikeE Posted September 1, 2010 Share Posted September 1, 2010 Its turbulance surely, there's not going to be a steady state pressure gradient in the cabin? No doubt there's a difference in pressure in the cabin and under the floor which would exert lift on the floor.
