Holden Commodore, Aerodynamics. AND NOW: WATER INJECTION...

[Danny Barrett]

Ammendment: I mean to say 2" drop from standard is normal, not 2" clearance
between the ground and the car...

D.B...


>I have to admit that I expected a few "shots." Mind you - it was only an
>experiment - the stuff definitely isn't there now!!! I didn't put it where
>the exhaust is (i didn't want it to melt and catch fire). Wouldn't the
>Polyprop sheet melt/catch on fire from the heat of the exhaust? Perhaps not
>(???) but I would prefer to be on the safe side of things (even if I did put
>duct tape under there)... So you weren't being "funny" with the 1/8"?!?!?!
>Somehow I don't think my car could get that low... But I'm told that about
>2" is quite normal for this type of vehicle... As for the gutter, I think it
>is screwed on with my car :) but I would have to check to make sure. Either
>way, it isn't welded on, as it is chromed (unlike the rest of the car). So
>at worst, it is onlt riveted on (I know for a fact that the gutter is EITHER
>screwed on, OR riveted on, but from memory, I think it is screwed on).
>Thanks for the tips. I'll see what happens.

>>>	I hope you didn't bite while you were writing this... Your tongue was
>>	obviously firmly planted in your cheek. 
>>Well yes, and no...
>>
>>5mm sheet of Polypropalyne is cheap and will flatten off the underside
>>of the car nicely.
>>Lowering a car to 1/8 inch off the ground is what I have been told is
>>the point at which formula1 ground effect was used in the 70's.
>>Deseaming has been widely regarded as a good way of cleaning a cars
>>aerodynamic profile. Some people cut off an entire seam and wonder why
>>their car 'pops' open ( don't laugh this was a common mistake with Mini
>>owners ) you should grind, weld, grind and weld along the seam/gutter no
>>more than 4 inches at a time.... best that you do not start at one end
>>and move along, cut 4 inches,weld, leave a gap of 4 inches then cut
>>futher up  ____----____----____----____----    then do the bits that you
>>leave.
>>On the works Triumph TR8 they deseamed and welded a roll cage in at the
>>same time ( actually splitting the skin of the internal mounts and
>>pillars welding the cage in then welding through the cat seam on the
>>outside... that car was stiff and safe.
>>
>>>	Thanks for the ideas anyway (however sarcastic some of
>>	them may be :) 
>>
>>Sarcastic??? oh you mean the skip!  That may have been ( you knew this
>>because the skip idea would  damage the radiator )...  But surely you
>>will allow a man to joke?  No oh well then.
>>But you cannot seriously mention Duct tape and not expect a shot across
>>the bows, can you?
