If they accept the artwork, they will create the shirt with lots of options (short sleeve, long sleeve, sweatshirt, etc) and post it on their website. They make them all limited editions and are only available for a few days.
They have great quality and good pricing. If they accept it, Ill order one for you

You-Are-a-Top-Man!!! Fingers crossed in that case
Keep us posted, I'll go spray the Boxster S with more air in a meantime (tell me when you had enough loll)

@Fred - I wish I had your toys. I always enjoyed CFD when I was modelling furnaces for heat treatment. Sadly retirement took those toys away. Great rasters Fred!  |
I'm in for one in XL too.

One tiny detail, and you should only care if you're really anal about these things - which I am.
The picture is not of a Boxster S.

Hm, i don't know. There must be something wrong with the calculations.  Because the top speed of the car is faster with the top closed than with the top open.
Maybe you can recalculate at 260 Km/h?
Regards, Markus
PS:
Great - i need 1 2:

Markus, we'll never be able to make friend if you continue your rampage man LOL
************************************************** *****************
Here goes the real deal. Same: 180km/hr. Enough 'wallpapers' and 'streamlines' otherwise it all leads to confusions and members mocking up the mighty Boxster's science-of-winds!
Those familiar with CFD, I'm using using the K-Epsilon turbulence model here so this is as accurate/advanced as real-life as it possibly can be. Commercially available to us anyway. Hopefully next week when all have recovered from seeing green & yellow I'll push those same but with the topless boxster (same format/grid, so to de-comfuse Markus).
Have fun (TRK!)

What?
Man, now i know what happened. You've used a cheap chinese 3D model for you calculations.
Just compare the silhouette of the real car with your 3D CAD car.  No wonder, that the top down is faster than the top closed.
Regards, Markus

Silly me. I'll contact Dr Yang Procshe to get this fixed right away. Totally (totally) unacceptable and unreasonable.
Jeez don't they know who I am and where I'm from?
Wroom wroom!

Huh, apart from some drag, I'm not seeing much down force effect at the spoiler.
Perhaps Boxsters need whale tails 
Fascinating results though, thanks for posting them.

You are very welcome Sir
That spoiler thing does somehow get cancelled at speed, for some reason. Boxster wasn't necessarily designed for racing I think.
Me think you are 100% correct about the requirement for a wing on the "track only" 986. But again, not a 'car mosport' professional at all here. Just leaving those here for you guys to judge

Dear Sir Mr. Nine8six,
could you please ask Dr. Yang Proshche if there is a mistake in the pictures. Because besides the text the picture looks the same, whereas at the open top pictures they look different.
Honestly, your how can we be rampage friends guy.

That's because a spoiler does not create down force, it reduces lift

Deleted - misleading grid.
if Jay doesn't understand it I don't think many will.

Edit: you know what bud, I've delete this grid because this will be interpreted wrongly by ppl... you can imagine what could happen next.
Better be safer than sorry lolll Let's just look at the pretty pics... not real-life but at least we have something to compare with.

There you go, special for you Markus. Took a snapshoot of my super duper Virtual Boxster Z in "perspective" mode just like your friend's did with his camera lens. Those simulation plots weren't screen-captured in perspective mode (and a bit dark) but if you want them like that next time, hey man, me-can-do-special-fo-yu
Wroooooom!

Markus Markus Markus... they are everywhere on my hard drives here, all in CAD, class A&B surfaces, G2/3 curve continuity and all man. Markus.... its crazy, I have a Virtual Porsche Inventory. Which is faster on a windy day you think?! the Carrera or GT4?
(lolll I think I win a price for the most picture intensive thread page ever recorded)

I was wondering if the major difference in those profile shots (aside from perspective) was that yours was a center-line cross section. No display of fender contours?
