My mistake. Got confused with the starter mounting being cut off. :oops:

Bit of a new idea to go with the light weight daily driver.
What are peoples ideas on reducing aero drag. I was thinking about the air traveling through the engine bay and out the wheel arches which from memory creates lift.
If you were to block off the wheel arches and under the subframe (seal them to the subframe and body), mount a radiator behind the grill and duct the air through the top of the bonnet.
In my theory this would eliminate the lift created from the air escaping through the arches and under the car and also create some down force by all the air going through the grill has to then travel up through the bonnet vents (styled similar to the EVO bonnet).

Yes but lift is a good thing. If you want your car to weigh less then you need to create a high pressure under the car.

If you want it to have gain aerodynamic downforce then you need to get everything sorted like diffusers and wings on the front (not on the rear its a negative effect for a mini). But ultimately without a wind tunnel its useless.

the only time you need down force is under acceleration & through corners otherwise i would consider it drag

Was that in Mini Magic? Looks familiar.

It might not be relevant to the OP but...
what your saying is true, but in a racing environment, sometimes its better to increase down force so you can get around corners quicker than is it to get the best straight line speed in the straights...

Look at the RedBull F1 cars this season... they corner so fast is doesn't matter they are slower on straights..

same for NASCARs... they crab like a mofo down the straights just so they can get into and off the corners at higher speeds.


more on topic tho.... if you blocked up the undercarriage and made it quite smooth is should make a fairly decent improvement to the aerodynamics.

maybe chopping/ reshaping roof, Mini Monaco style would help aerodynamics as well... not really a cheap option tho

agreed, best to have improved handling on a mini especially. just depends on what kind of motorsport, track i expect? the F1 cars can produce enough downforce to stick them to a tunnel roof....don't think he'll need that much though :lol: ... how about fitting a front & rear under diffuser & cannard set?
If going all out you could build a chromolly spaceframe & purchase a fibreglass shell

This probably weighs a bit less than the standars car, and would be more aerodynamic too: :lol:

might have to wear some aerodynamic threads to stop it from pulling to the right...anyone?Image

But can they stick to tunnel roofs with another one in front killing the airstream?

behind another car they are lucky to stick to the bottom of the tunnel... let alone the top!

Thats the reason i dont like aero.

Plus i just dont have the patience to analyse miniscule changes in angles of wings.
