Anyone ever find a drag coefficient for our cars?

with our without rear or front spoilers? The rear spoiler probably increases the drag a few decimals.

"stocks":

1) '62 Shelby Cobra 260.......12,90 @ 114..........4 spd.

 

Or, so they say :s

Dad's 260 Tiger only mustered, IIRC, a 16.4-ish @ somewhere in the mid-80 range back in the early '80's. Close ratio toploader (way too tall 1st gear for launching), a whopping 150 advertised HP and near zero traction didn't help... wound up the springs and wheelhopped BAD if it actually did get any (needed Traction Masters). With it's current (ahem, installed in the early '90's) Dunlop "big" rubber on it, it won't spin tire. Period.

A 15.99 woulda been cool that day.

 

I'll have to dig up that Keystone Raceway time card. It's probably still in the console.

 

Car was so stock at that time, probably still had its original antifreeze :)

And that I can vouch for.

 

Good stuff, all. Neat topic. I imagine that the vertical taillamp panel on our '72-73's added more drag than any other component.

Wonder if someone like Dark Horse Racing or any Bonneville racers has any info to view? Would be interesting to see, just for fun.

 

The Cobra's were set up different than the stock Tigers with the 2 barrel and cast exhaust manifolds. A lot of Tigers got the "LAT" options that could include solid lifters, 4 barrel intake and carb, headers, etc., like the Cobra's got. My Tiger has most of the performance LAT options, including the Traction Masters and locking rear end. With the performance options, the Tiger 260 was rated at 245 HP. With that said, yes, it's a dog off the line, relatively speaking. It was meant for road racing, not drag racing. They're quick, but not smoking tires, front end in the air, quick. Mine does still surprise some of the Honda guys with the coffee can mufflers though, when the fat, bald, old guy in the "British 4 banger car" eats their lunch.

The vertical tail may actually reduce the drag. It's called a kammback.

I remember an article about how everyone thought the Camaro was more aerodynamic than Mustangs, but the Mustangs had the edge with the drag coefficient. Might be the same one that Hemi is thinking about. I'm pretty sure it was about out generation of cars. I've tried to find it, but no luck, so far.
