Air Foils and Splitters

My car (08 MCS JCW [engine only not JCW body]) has no splitter and the only foil is the factory one(that 'divet' above the rear window). I have driven it to above(the speedo only goes to 150mph and the needle was buried) 150mph and the front wheels didn't seem light. So in the case of a street MCS ,do we really need splitters and foils?:cornut: Jason

 

Downforce = drag

While going through the upper Ss at VIR with the peddle to the metal you'll want more downforce but on the street it can and will reduce MPG. I have a small splitter and lost about one MPG overall...

Trick is, is getting the downforce you want with the least possible amount of drag.

 

Seeing how I know for a fact that you don't track. It's nice to know you are driving around Dallas at over 150mph.:rolleyes5:

 

Graham, ie "Track-Toy", is working on a track solution that hopefully we'll be able to buy ourselves.

 

Not In Dallas

:frown2: I live in Sherman,Grayson County, TX 70mi from Dallas.Jason

 

But it's only a 20 minute drive. I call BS on 150+ mph. The MINI doesn't have enough power to overcome it's signicant drag.

 

Let us tread lightly here, folks. I am just saying.

 

I agree. The friendly live and let live is why I came here.:cornut: Jason

 

Not specificaly splitters and aerofoils, but there are some pretty cool wind tunnel shots here, including the MINI:



Compared to the other cars, you can see the turbulent zone at the boot.

 

Cool link -- thanks

 

Yeah, pretty neat. It is interesting to look at the lift and downforces (front vs back) on the different cars.

The MINI's air drag index (0.73) doesn't seem so bad compared to some of the other cars, but of course it may not have the same power to overcome that drag.

 

Drag/Topend MCS/JCW

Thankyou very much. Now I know that the nay-sayers that would have us believe that the MCS JCW has the aerodynamics of a brick with velcro and therefore cannot achieve published top end, are incorrect. Over on Motoring File they list top speed of MCS JCW as 149mph and Mini/BMW are known to list very conservative numbers(for insurance purposes I'm told). Thanks for the info on all the cars.:cornut: Jason PS,does that 'little divot' spoiler actually do anything helpful. It appears to (in the tunnel photo) decrease rear turbulence/drag but I'm no engineer so...what do you think?
