what's a more effective way? They were going cheap and easy, I want light weight and not a fuckton of money. I'm still hoping I'm gonna find plastic I can glue to my car thats like garbage or something

 

Cover the car in a layer of greatstuff foam (or whatever its called) let it set, sand the foam to the cars contours, get some sort of rounded sanding cups and attatch to a drill

Actually, the rough surface of the sanded foam might be enough to cause the surface turbulence they were trying to create

 

I was thinking about foam too, I went to the grocery store thinking they've got dimpled foam trays for produce but the shape didnt look right.

I'm gonna get some of that foam and see how weather/wind resistant it is. Thanks for the idea buddy

 

I got some quotes for sheets of 1inch and 2 inch foam boards, then I can use scrap materials and that foam to fill in cracks before I shape the body and do the dimples.

its 50$ per 10sq ft 1" thick, 100 for 2" thick. A couple cans of great stuff to fill in the cracks. Some super glue to put it all together .

fiber glass I have no clue how much that would cost I haven't used fiber glass in years and years.

then paint the bitch up it'l look fresh and also crazy.

It'd be nice if people weren't shoving **** in my threads all the time "that doesn't work"

"I read about this build people do and they get better MPG"
"nu uh thats not how manifolds and cams work"
"okay"

"golf ball car? Golf ball car."
popular mechanics: dimples dont work, the only testimony is some motorcycle rider who says he got 3mph out of em
"okay "

I'm gonna do this all scientific and someone did say I should have my own baseline. What if my motor only gets 29mpg because ethanol and whatever? And I assume it should get 35 un-modified? Thats not scientific.

science takes patience and ideas take planning mr mark. Besides I still need my last gasket to put my POS engine back together

 

Still talking.
If you actually got paid to produce something you'd be on food stamps right now.

And if you think you're a scientist, I havea bridge to sell you.

 

So,

Dimpling a car is a good method to demonstrate why a golf ball works the way it works, but a pretty inefficient method of actually increasing the aero efficiency of the car. The whole point is to inhibit flow separation, something that could also be achieved with vortex generators, tripping tabs, and at the extreme end, with kambacks and boat tails.

Also, to promote the turbulence that helps tumble the wake into the low pressure zone behind the car, the surface has to do work on the air. While the net effect is less drag, you're still doing work on the fluid to get a slightly more back out of it.

If you really want to have a dimpled car, cool. If you actually want to increase mileage, there's fruit way lower on the tree.

 

I'm sure there is I plan on doing several things. First on the list is the digital MPG gauge for OBD1, and the vacuum gauge so I can drive as efficiently as possible and keep track of how the car does, a base line.

then an intake cone filter (ram not cold), and a tune. See how much I can get out of the engine without real mods.

IV seen people have success with enlarged ports and intake/exhaust and a cam, dunno how thats suppose to work but the results are hard to argue against.

and finally the last thing I have came up with so far is the fiberglass foam dimples. Needless to say hyper MPG build is very dumb.

 

Easiest way to do this is to drive the car onto a live driving range. Golf ball dimples, all done.

 

this **** will never work on a car because a golf ball flies through the air spinning in a forward motion, I'm pretty sure you cant drive a car down the road in the same manner. Stupid Idea.

 

even tho my name is accord this is happening to a civic, much lighter than my 4,000lb accord. Most aeromods create downforce and that increases traction and also friction, which is not what I want.

dimples were shown scientifically to increase gas mileage by 11% in initial testing, and it ended there. I'll see how well I can do with a light weight dimple skin
