SPAL Ranger Aero Ideas? Rocket Ranger




http://www.pickuptruck.com/html/news/rocketranger.html

Looks like:
Lowered
Side Skirts
Bumper Grille Block
Bumper Skirt
Bed Cover
Smoothie Wheel Covers
V8
Mirror Delete

Everything but the last 3 I can do
-Wheel covers cover shiney chrome!
-V8 not mpg friendly
-Texas requires atleast 2 rearviewing mirrors..

Anything else I might have missed?

The exterior of the Rocket Ranger is nearly identical to that of a stock, 2002 Ford Ranger. Indeed, to compete in the SCTA/BNI-sanctioned Modified Mid/Mini Pickup class, a vehicle must be unaltered in height, length and width; the body panels must be mounted in their original relationship to each other and the pickup bed must be fully stock and original. In the case of the Rocket Ranger, even the bed's tonneau cover is stock and available to customers.

don't see one.
Huh? wonder why they went with the Edge? you'd think the torsion bar brackets would hang down into the air on the bottom. Unless they painted everything, but i think they wasted money on painting the bumpers and Fender flares then.
Oh Fx, lose the fender flares, i'm sure that could help cut down on aero.

Running different sized wheels to generate downforce might be fine on a high speed run, but it will only increase drag in a fuel economy setting. Lowest drag should be achieved at an angle of attack of ~0.

I think an aerocap for the bed would be the most beneficial addition...I wonder why the rocket ranger didn't use one? All the other mods seem worthwhile (except the V8...).

Thumbs up

The 2nd edition of the truck looks a little different in this article...and a whole lot less stock.

Another article shows a better front view...

More piccies...

I noticed there isn't any visible belly pans...I guess the front air dam is pushing so much air that any belly pan isn't a factor at that speed...

Looks like an edge but doubt it has much edge left.. and I plan to get rid of the flares..

So a level truck is best? no rake?

I might make an aerocap during the summer, looks simple enough..

It might be beneficial to the Cd, though nothing I've read comes back to mind in this regard, but it's detrimental to frontal area, not that it matters considering the air dams they tend to stick in front anyway.

Bondo (Brett) mentioned somewhere that the aero cap creates a lot of lift, which would be very bad at the speeds these trucks go. This is what happens with lift at 200mph:


On the plus side, you get a good view of the belly pan!

The fences on the roof are there to prevent that. There also very prominent in nascar now.
