Down at AAS yesterday. All the modified cars had huge spoilers. I thought 8" was the limit, but it looked more like a foot. Got to figure out what is legal and get one of those puppies on 222. |

QUOTE(PeeGreen 914 @ May 23 2011, 12:13 PM)  That article tested downforce on an old mini cooper hill climb car.Using various size splitters and at different wind tunnel speeds (not alot of data-they did not test as much as I wish)The tests conclusively added downforce in even the smallest splitters (30 MM test) and showed 80 lbs of downforce on and 80mm splitter at 80 miles per hour.There tests showed that if your rules allowed-you have to run as much splitter as the rules allowed-that you could still balance cars handling All that being said,hypothetically of course-if you had an autox car that weighed 435 lbs per front corner-and at maybe 70 (typical national level speeds in FP) the car weighed 70 ish lbs in front-so now front end has an increase of 35 lbs-so your 470 in front??maybe???? splitter weighs 5 76 bumper,mounts,frame-13 Noticed that you want car planted at 30MPH but for really fast times-it neeeeds to be planted at 70.All hypothetical of course.JJackson |
