As well as my little engine bay play, I`ve also worked on the aerodynamics of the car while it`s been off the road.
Now, creating downforce is no problem. just bolt on a huge wing and away you go.
This has a downside, drag!!
The Puma, for all it`s qualities in the twisty bits, suffers a little along the straights from lack of pure grunt.
So I have been looking into ways of creating extra grip without extra drag, No mean feat.
But I have come up with something of a solution.
At this years Fordfair I got to meet and chat with forum member, Sjoerd (and have a good look at his car) As some of you may know he has done a lot of very clever investigation in this field. And has plumbed for a gurney flap.
These things tick all the boxes, very little drag for significant downforce.
I recon our cars don`t actually need that much extra downforce at the rear as they handle so well already, but a bit more can`t be bad.
So I set out to find one. not easy I assure you.
In the end I found a company selling BMW saloon boot spoilers, which turned out to be exactly what I wanted.
after a few emails I arranged a custom length to be supplied (Beemer ones would have been too short) and have set about fitting it this weekend as well as a bit more smoothing out on the body.
This is what I have ended up with. I`ll let you all know how it performs (whether it makes any difference!) after Cadwell.
