not the same buuuuuuuuuuuuut,

more an exercise in relocating air from the high pressure zone.

Larry's Old Volks Home Ghia Land Speed Racer | MyRideisMe.com

i met larry in the early 90s @ el mirage same car, same engine but big aero mod is now missing :[

when i saw it it was green and larry said it exhibited a funny problem.
@ 120 mph the front would begin to lift gently. to alleviate the problem he
ran an 8" wide and 2" thick oval tube which evacuated air from the center of the bottom front of the vehicle (which was causing the lift from air damming up)
through the car longitudinally exiting right behind the bottom part of the rear window. unfortunately he ended up in a higher speed class because of that mod. i dont see the tube installed anywhere, therefore i think he ditched it
in favor of much more depleted uranium. he seems to be running just marginally faster then he did when i met him which makes me wonder if he is running in his intended class again but has now gotten serious about making some power (to overcome the additional loading from the newly added ballast) by chilling his intake air.

i have a sheet of acrylic waiting to replace the heavy glass rear window in
one of my rabbits and am pondering to punch a hole in it for the same effect
but an entirely different reason.

while on the subject of compressed air... thinking of ways to reduce frontal
area on a bicycle type vehicle having pretty much exhausted the possibilities
attention went to the rear of the craft. a bike and rider punch quite a hole in
the air, farings of any kind are not allowed. with no ways of dealing with that
deficiency I mused the idea of intruducing massive ammounts of air to fix and
fill the void left by the bike and rider slowing him...
bicycles are made of metal tubing which could be sealed with some effort
a sudden *outburst* could prove to be quite an aid at an opportune time.
add some artificial methane and sulfer odorants and it would seem like the real thing -
virtually undetectable ;~>

anyone on here that is not math handipacked who would like to crunch some numbers target speed is 60 mph.
