Chris Wilson Posted October 18, 2005 Share Posted October 18, 2005 Just killing tme reading up on some aero tweaks for my new race car, and came upon a superb very techie site, and some info on what downforce the Group C Toyotas were making in the early nineties. See: http://www.mulsannescorner.com/aerodatabasetoyotamkiii.html Makes the MKIV rear "wing" look a bit sick! Quote Link to comment Share on other sites More sharing options...
JohnA Posted October 18, 2005 Share Posted October 18, 2005 the bi-plane wing was producing 7500lbs of downforce at 180mph, almost 30 times that of the supra at the same speed, lol... Quote Link to comment Share on other sites More sharing options...
Gordon F Posted October 18, 2005 Share Posted October 18, 2005 Do you remember the weight of the Group C car Chris? (Just to save me searching) the bi-plane wing was producing 7500lbs of downforce at 180mph, almost 30 times that of the supra at the same speed, lol... I think the figures are for the whole car, not just the rear wing. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 18, 2005 Author Share Posted October 18, 2005 832 kilos for the ealier car. See: http://www.mulsannescorner.com/toymkiii.html Quote Link to comment Share on other sites More sharing options...
TLicense Posted October 18, 2005 Share Posted October 18, 2005 To put that into pespective. A 2005 F1 car will make 3000lb of downforce and 1000lb of drag with a 3:1 efficiency at 240kph (VERY approximate figures) There's not a vast difference in any configurations any more, all circuits are pretty much max downforce nowadays.

Angie Posted October 18, 2005 Share Posted October 18, 2005 I've been looking at this sight for a couple of years now. When anyone tells you how fantastic their Audi TT is, just point them at this and see how much LIFT it generates!! http://www.mulsannescorner.com/aerodatabaseauditt00.html Lol!!!

TLicense Posted October 18, 2005 Share Posted October 18, 2005 All road cars will tend to produce a small amount of lift at speed. A large amount of downforce in a road car is inherently dangerous. Quote Link to comment Share on other sites More sharing options...
Angie Posted October 18, 2005 Share Posted October 18, 2005 All road cars will tend to produce a small amount of lift at speed. A large amount of downforce in a road car is inherently dangerous. In that case can I refer you to the Carrera GT: http://www.mulsannescorner.com/aerodatabaseporschecarreragt04.html and the 360 Modena: http://www.mulsannescorner.com/aerodatabaseferrari360modena99.html Nobody is saying anything about LARGE amounts of downforce in road cars. But as you can see, they don't ALL generate lift! Quote Link to comment Share on other sites More sharing options...
JohnA Posted October 19, 2005 Share Posted October 19, 2005 This is an excellent link Chris Shame there is no more data on 'everyday' cars, hell, even the new Beetle looks scary at top speed Quote Link to comment Share on other sites More sharing options...
Anh Posted October 20, 2005 Share Posted October 20, 2005 Nice trivial site, but not really useful data at all. I think all the numbers there are all racing team's claim or theoretical figures and that doesnt even explain what the distribution of downforce is like, which is just as important.
