High speed stability questions.

[1968FormulaS340]

Think 150mph for one hour.

Has anyone experimented with improving the high stability of a 67-69 Barracuda. I’m talking cleaning up the under car air flow. I was thinking a front splitter, rear diffuser, installing panels to smooth air flow. Anything cosmetically obvious would be unacceptable for me.

Good page on splitter theory. The page is for a BMW E30 M3 (a car I had for 4 years and just sold) but the info works on all cars.

I remember guys running these cars in the 70`s, would block off the area just above the front valance.They would also use two front spoilers similiar to those found on TA`s. There were some that also ran a rear spoiler from a Javelin,and the word was that they worked very well. Since these are all cosmetic changes you probably wouldn`t be interested but the key was to get the air moving over and around the car.

By cosmetic changes I mean I don't want a wing on my car. The TA spoilers sound interesting. Anyone have any info on how much lift a FB Barracuda develops at speed, both front and rear?

Any vehicle that reaches a speed of 80 to 100 miles per hour or so can become a flying projectile, dosn't matter if it's a go cart or a bus, they can all produce lift and go sailing. I find it very interesting that you should be talking about going 150 mph for an hour, you havn't been viewing a certain web site called http://www.silverstateclassic.com/ now have you???

Get into the time machine,
go back to 1968.

See the men racing the Barracuda's.

All that info is so old it will be hard to find.

The Mustang's, Cougar's, Camaro's had more luck.

['64 Cuda]

I just bought a June, 1966 issue of Popular Science because, according to the seller, it has an article "...describing unseen forces that affect driving and safety of the fastback auto design. The author uses the Barracuda and the 1965 Citroen as examples of air flow dynamics."

I have a '64 Barracuda so I thought it might be an interesting read. :downtown: It's hard to say how much of it will apply to the later body styles. I haven't received the magazine yet, but when I do I'll let you know if I find anything interesting in it.
