SH8KDWN Posted August 14, 2008 Report Share Posted August 14, 2008 Before I go off and buy a front splitter to start slicing and dicing to fit I figured I'd throw a couple questions out there. I know many here have more automotive fluid dynamics knowledge than I do so I appreciate your feedback.Going off the assumption that my rendition will look like the splitter below.1 - Will the increased downforce on the front of the car be noticeable? 2 - What handling characteristics can I expect to change? (ex; increased understeer, twitchier steering?)Several here have run a similar splitter for the 850 series. I'm curious to see if there was any difference at all in performance (as claimed by some companies that sell this type of product). Perhaps it ends up being more of a cosmetic mod until you reach mach IV. Link to comment Share on other sites More sharing options...

Perhaps it ends up being more of a cosmetic mod until you reach mach IV. to be honest, i cant really say if there are performance gains.. but i did notice a little difference from the stock 850 bumper to the R bumper, i felt that it helped the car aerodynamically on the hi-way.. but defintely a splitter will make the car LOOK faster hahahahaha Link to comment Share on other sites More sharing options...
NoodleKnight Posted August 14, 2008 Report Share Posted August 14, 2008 I think a properly designed one is designed to move air around the sides of the car, rather than under, helping with higher speed stability. Well, bumper design also plays a significant role. For the most part I think that most splitters sold for our street cars are purely cosmetic. Also I suppose they're good for scraping the curb.Correct me if I'm wrong though; this sounds like a question for Chuck. Link to comment Share on other sites More sharing options...
JCviggen Posted August 14, 2008 Report Share Posted August 14, 2008 You can make the car more stable at high speeds but not really create downforce (or reduce lift) with anything sensible looking like that.Making a big skidplate that closes off the engine bay from below also helps considerably with stabilizing airflow.

shanehutton Posted August 14, 2008 Report Share Posted August 14, 2008 For a front splitter to have a noticeable effect it would have to be quite close to the ground. If anything, you may actually increase lift if it ends up angled wrong. It would be purely cosmetic. Link to comment Share on other sites More sharing options...

It will stick out further than the VST lip spoiler as well as having more surface area to contact the air but it still may be insignificant.The typical splitter will leave a 3"-4" exposed lip with the other approx 20" or so extending under the front of the car. This may act as a skidplate and reduce chaotic flow from below. Link to comment Share on other sites More sharing options...
Che'_Moderator Posted August 14, 2008 Report Share Posted August 14, 2008 What a mess.Ok first of I have worked with that specific splitter and seen the wind tunnel tests on that car. The pictures make the splitter look different than it does in real life. Its actually made from a 2D thick laminate. This picture gives you a little better idea:Second the two major sources for downforce on that car are the fenders and the rear wing. The task of moving around the car falls on the turning vanes not the splitter. So what is a splitters job. 1 it makes the car longer. Longer vehicle = higher drag limit. Secondly they can be used for down force but require stay bars. So look at it like this. They can provide down force in one of two ways. Removing lift or increasing front end weight. Do not confuse them though, 700 negated is not the same as 700 pounds of down force added. IF you want to start adding down force you have to make sure the chassis and part can handle it. IE if your wing will produce 1000 pounds of downforce at 100mph, you better make sure your drunk or air dam can hold 1000 pounds. Back on point. The splitter in that picture is not canted down to produce downforce. If it were it would have a large effect on the car. If you make your own and cant it, it will have a large effect on the car. Just remember its going need ties to the cars chassis and sub frame unless you want to make speed bumps.Edit: The one on the S60R GT car is not cosmetic :rolleyes: Link to comment Share on other sites More sharing options...
SH8KDWN Posted August 14, 2008 Author Report Share Posted August 14, 2008 Thanks Chuck, I appreciate the input. I think I would add anchors like the ones pictured below as well as button up the front by fastening the splitter as far back as it reaches (see other pic).http://www.rallysportdirect.com/shop/image..._front-side.jpghttp://www.vividracing.com/catalog/wm.php/...prsplitter5.jpgI can start with a level install and cant the splitter with an adjustable achor and spacers on the fasteners if I see fit. Thanks again for the explaination. Do you have any pictures if the turning vanes? I loosely understand how they work on an F1 car but cannot picture how to incorporate a turning vane into a closed well wheel set-up. Link to comment Share on other sites More sharing options...
