Vmax with GT3 aerokit?

[alter_schwede]

hey all,

we know that the stock 3.4L aero dynamic get a Vmax of 275km/h and what about GT3 mk1 aerokit, loss of Vmax?

cause last Sunday, I tried out Vmax on my 3.4L with stock air paper filter, GT3 front bumper and a set of TurboII rims with 285/30 at the back, and my digi tacho came up to 278km/h,

which is of course not the true speed, I know my tacho has about 5km/h faults.

so I'm interested to hear your expereince with your aero dynamic tuning?

cheers,

Tony

Hey Alter Schwede,

is 278km/h all? IMHO that should be a bit more.... My 996 3.6l quite easily hits the 300km/h mark (305max), so a 3.4l even with an AeroKit should be faster.

hey Wolfgang,

aerokit will unfortunately lower your top speed due to the larger areas on the bumper, with that the air restistance are much higher and a better downforce.

the more downforce you get, the less top speed, that's the physic of nature!

a very good example are between C4 and C4S, C4 max 285km/h and C4S 280km/h, according to Porsche official tech info, due to the Turbo aerodynamic but with same engine.

cheers,

Tony

Hi Toni,

agreed, the C4S is definitly slower than a C4. The drag coefficient is about the same, but with the Turbo body you have a bigger surface area. That's one reason why Ruf merges hot engines with slim Carrera bodies.

But I think our discussion is quite irrelevant for most parts of the world anyway B) as only here in Germany you can (legally) try top speed on an empty Autobahn.

:drive:

cu one sunday morning on the A81?
