How much downforce you want to make really depends on how fast you want to go. The % increases in downforce are directly proportional to % increases on grip. I think everyone is trying to make aerodynamics more complicated than it really is and really lose sight of what aerodynamics is for: creating a pressure differential. |

I completely agree with you on the muffler angle but those dimples are spot welds from the internal baffling. There was a big to-do about the dimpled vinyl that was being sold for Motorsport use a few years ago so one of the NASCAR teams did some testing. They found the dimpled surface on a golf ball works because it a rotating body and didn't really apply or work the same on a non rotating surface. When I'm not on my phone ill look for the article and post it up. |

speaking of aerodynamics, does anyone else get this pattern on the hood when dirty?

Speaking of anyone notice.. Anyone notice how much the car really prefers clean air? Been watching the instant MPG while approaching other vehicles on the highway. Every other vehicle I've done this with, I always noticed a slight rise in MPGs when in the turbulent draft. This car, it seems to go the other direction, and picks back up after passing the other vehicle. Granted, I haven't tried any 2" off the bumper NASCAR drafting or anything, but interesting how this car pokes its way through the atmosphere. |

nice to see CFD analysis guys on here, about a year ago i went through a crash course on aerodynamics and CFD, but it was with a Boeing engineer...so its a lot different to car modeling.
I really should port my 3dmax models into solidworks.

real good my car feels looser from 5k in 4th on up in speed in all high speed corners at laguna Seca with the new exhaust. Evo X has the same design but you want to loosen them up!

I felt this way from day 1. I went looking for a nice low profile wing that is effective and have not found it. A little thing that helped was lower the front of the car a little more than the rear. This also seems to make the front brakes bite, maybe it's just me. |
