johnc Posted September 25, 2008 Share Posted September 25, 2008 String shows flow, not pressure. Quote Link to comment Share on other sites More sharing options...
blackwidow Posted September 25, 2008 Share Posted September 25, 2008 Let me see if i can find the pics, but i have/had pics of a car doing this and where there should be low pressure zones the strings were pointing toward the sky as if something was sucking them up.

blackwidow Posted September 27, 2008 Share Posted September 27, 2008 Havent been able to track down the pics yet but here is what I'm talking about with the low pressure zone to use for the radiator/intercooler if you have one. http://www.up22.com/Aerodynamics.htm about in the middle of this doc you will sea pic show natural low and high pressure areas on most cars. There is usually always one on the front tip of the hood. That is where you would make your outlet. Plus that page is pretty informative for people new to aero. EDIT::::This is another intresting article. http://autospeed.com/cms/A_108656/article.html?popularArticle I think my pics of this being done to a Mk1 Mr2 were on my old laptop that took a crap on me. I had lots of good things on that laptop that I am having to find all over again, but now i have an external hard drive. To everyone that has lots of info that you have many many hours researching into the wee morning, kinda like me now, i would reccomend a external hdd to back up your info every once in a while. Anyway in the article he states that some of the tufts will stand straight up and some will even point backwards to the way you think the flow would be going. Pretty neat stuff if anyone has any spare time with their z. Quote Link to comment Share on other sites More sharing options...
