That shredded material does get heavy after a while of letting it cake up there. It really builds up in the well more than anyplace else.
aaahhhh, shredded velvet rope when burning out from the front of Studio 54 years ago. LOL.

I'll post the drawing to the install when I get it tomorrow.

Been looking under new cars for ideas and some are amazing yet simple and functional. I'm going to grab a couple of black plastic belly pans from a car or two and start fittin n cuttin. The back is more of a parachute than the front and after a few 100+ mph runs, my foam sump plug for my cell is no longer in place and dirt/dust fills my trunk. Also tore off the turbulent parachute 6-pack scoop and am going to the old pro-stock 2-piece scoop except I will put a modern aero scoop on top to help even more. Most want more power but a good aero plan can have great effects above even 70 mph from what I see on my Dart............

While the weather is choppy and the crickets are singing, I'll let y'all maul on this one for a minute. Since it looks rather non car-ish to begin with, I'll fill in some of the spots to make it easier.
It's a home made jig made with discarded wood as you can see and it has to do with what will be done with remounting the bumper up front.

This thread is awesome! I think the original title asks something about the costs involved?

I lost count last time I was at the round table for the countries fiscal plan. LOL.
Quite honestly, when you're having fun and inventing which in itself makes it pricey with those pesky one of none items, costs goes out the door. But the love of Hot Rodding steps in.

I have on many occasions made stuff from free found objects including light alloys. The fasteners and welding services is another animal, but one can take their time and incrementally purchase stuff.

I know all about the losing count... In the long run it's all in the enjoyment of the hobby. I get a lot of joy from my own stuff but I also really like reading and seeing what other Mopar brethren are up to.

So itsa bumper BRA??

Itis, You got it. It's a wind spoiler to direct air around the front end. LOL

I'll post up a flick later to show what it is for.

Seems as the fever is prevalent more than we think among ourselves here. As our Hemi-itis has said; "The condition seems to be fully blown".

When I first crawled under my GTI it was fairly surprising. The entire thing is covered in belly pans, with naca duct looking cutouts for brake and oil cooler ventilation. You can't even find the framerail to throw a jackstand under it. I guess it's all worth it for fuel mileage. Probably doesn't hurt the little hatchback at 150mph either

Like I've said before, there is a whole lot of real estate to manage underneath a car compared to the topside. Wind is very evident underneath.
Some cars chassis, mine included, look like the New York skyline upside down.
In that respect, painting stuff with more slick/slippery gloss paint helps it to be just that, slippery. But it does not hurt at all with the exception of cooling ducts to have it be more streamline with lightweight panels to evict unwanted turbulence.

Started grinding and smoothing in the valley today.Some loss with me hard to measure. It is what it will be,,,,or used to be

Grinding and smoothing what? Lifter valley in the block?

Yes,and just generally smoothing the lifter boss and block.

A lot can be said for a smooth/fast return of the oil by those and other valley mods.....................

Not that this is weight loss conscious, but it does show where I've kept things stock more or less for weight distribution. Now, that distribution creates another phenomenon which ThumperDart brought up, Parachuting.
Below is the example of a catch basin bumper and thus, the reason for creating lightweight air foils to attach to it to close off that basin and smooth the winds.

65' AFX Altereds did the same, but for the front of the car.

I'll bet mine without the stock fuel tank is even worse.
Doug

A STEEL J bolt on the gas tank???

Lee is that a one off gas tank or something that's available aftermarket...

DVW

Oh yeah, It's almost like having an upside down six pack scoop underneath with no escape for the wind. The amount of space between the chassis and ground is what??? 24" at best. At least a six pack scoop has open air around itself to escape up top on the hood.
I could not find my drawing yesterday, but when I return from Detroit on Monday, I'll look again and post it.

Plus, both 64' and 65' as far as Dodges are concerned share the same rear bumper. It may be a little different on the Plymouth's, but not far apart.

Skicker, Runnin' out the door at the moment, but I'll explain the tank later.
