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)

[Smallblock454]

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?

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.

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!

[Nine8Six]

So I went to Dr Yang Proshche to complain but came back emptied hands.

Even the part when I told him where my ancestors comes from had-no-effect whatsoever. He asked WHY you need this model so perfectly accurate then? So I shown him what I do and he suddenly became all agitated and started acting all weird. Not very used with this type of f'ed up behavior so I quickly left and did those for you guys - nonetheless

Fascinating comparaisons

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!

[Nine8Six]

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?

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.

[JayG]

^^^^^^
OK Fred, what does all that mean????

[Nine8Six]

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.

This has gotten all way over my head. Can we get back to the important (to me) part? Since links from other vendors are now blocked on this forum, how can I find out where to put my order in for one of the T shirts? At our HPDE's most of the time we need to wear long sleeve T shirts so I'd like to get one of these in long sleeves if it can be ordered.

If impatient, I've made this for fun and it came out pretty nicely. They also have hoodies which I'm thinking of getting if Jay's deal does not work out. Can be grabbed at:

No idea RE quality of the fabric however, based on luck. Unless any of you guys know please let us know.

EDIT: Use below visual to make your own t-shirt. [/B]I've modified the layout a little (click below to dwload HD version):

If blipshift accepts the shirt, I'll post a link here. Blipshift only sells a design for a few days

Damn, when will you guys learn how to spell Procshe correctly?

Also think of alternative fonts. That's very popular - like alternative news - great!

I've got you covered Markus, I can make you a decal:

Tatoo'ed and all :b

love it. a guy posts some really interesting aerodynamic analysis and all we see are pretty colours and want to make tshirts. viva the internet.
