'special roof or even a residential building' Loving the translation there boatbuilder . But at least I know my plan to fill in the 'roof rack' is a 'gooden'.


Re the vents in the rear panel. Could you test it by jamming open the 'numberplate' flap?

I had the same problem with mine, I'm sure the spare wheel holder doesn't help its like a big wing.
I'm running 260bhp from a Scooby engine - and Aiden built me a gear box which apparently is good for 144mph
I've had her up to 120 so far - on a closed road obviously - it kind stops getting any faster after that - as I guess it's not slippy enough to go any faster

I thought of two solutions

1) fit a Thule roof rack spoiler above the cab (mines a pickup) this works well - might try a less abrupt angle soon



2) I'm going to see if I can mount my charge cooler rad inside the spare wheel holder and drop it down slightly at the front with a spacer and longer bolts so the air pushes down on to it rather than up from the bottom

Geared for 144mph

Pickup trucks are always better with a rigid tonneau over the dropsides it would seem. Mythbusters proved it after testing with tailgate up/down/removed/covered.

So it must be true

Aah nice.
Yeh might see if I can get some carbon loveliness
And maybe a huge GT wing

my old van had a different engine lid arrangement and at speeds of 100mph or more the engine cover used to lift , so to cure this i always added weight to the cover when driving at motorway speeds

I currently have to carry 50 liters of water when I'm at Castle coombe race track.
Just to keep the rear wheels in traction

Jeez! I'm just trying to keep the front wheels on the floor at 50mph! It's another world! Take you point about the wheel carrier underneath though.

looks like someone was a high top fan in devising the experiment to make them look good by using the Dehler...
I'd bet a westie high top in particular would have more drag than the pop-top...

Um, no actually - see AdrianC's post earlier in the thread

The pop-top seems to perform slightly worse because the transitions aren't so good

aah yes,
Missed that one, I do like it when evidence tramples on my preconcieved notions!!

Aerodynamics - when we drive bricks.

Yeh, when you wanna push one through the air at 80 +
It's nice to know you aren't gonna damage the china.

We could put a positive spin on and call it "High speed braking assistance"

Bricks or not, it still has to push the air out of the way. Not all these vans are driven around at 45 mph

Maybe we should make a great big nose cone like Concord
