Coroplast fairing work around front wheel.


Beginning of a boat tail:

[Weather Spotter]

looking good!

Do you collect a lot of dirt in the coroplast fairings?

I can't believe that thing has attached flow! Frame is looking good. Be prepared to do custom wiring, as the car probably wasn't designed to tow stuff (trailer lights).

What's the reasoning for getting more caster?

[arcosine]

I like how it drives with more caster, wheels straighten out faster though turns. Not much dirt under the coroplast, wheel wells are fairly well sealed. I had pe foam stuck in but it came out and made a loud scraping sound on the tire, but without consequence. I'll try not to short the turn signal wire to ground.

What did you decide for the trunk area ?
It seems as if you could create a lighterweight one than stock that is actually the full length of the tail and uses the stock hinge points
It could then simply lock down with quick release fasteners.

I would imagine that it would be hard to cantilever the entire tail off those hinge points, if that's what you're asking. It would be a good idea to remove the trunk lid for weight savings, as the tail will add that weight right back on.

The stock trunk lid is actually pretty light and keeps water out. At this point I am not risking a trunk full of sopping wet stuff after a rain. I have my eyes out for one that I can cut up, but they want $55 at U-pull-it.

Welded frame tonight, might add some diagonal braces.

Just dreaming today...

I bolted the frame to the car today, not without some intrepidation.

I used lag bolts into the plastic body, not real strong.

I wired up the tail lights and brake lights. I bought 14 gauge wire, but looking at the saturn wiring, 16 gauge would have worked. I soldered the ground wire to the frame. I have a set of motorcycle turn signals, but the lamp holders are too corroded to use, to bad....they were nice and small with parabolic reflectors. Looks like the licence plate is too big to fit in the flat. I 'll have to tilt it to make it narrower.

I bought some 12 volt SMD LED strips off e-bay, They seem bright enough.

I an going to weld on one more cross member near the bumper, finish the lights and then skin it. Hopefully it will be ready in time for the foxhunt tonight. http://w9sro.org/foxhuntreports.html

Tail and brake lights wired up. Have a wire for turn signals too: I used the $5.45 light with amber front lens, I covered the inside with foil. They are brighter, when looking straight in, than the stock tail lights. [IMGhttp://www.flickr.com/photos/26437850@N02/8172328858/in/photostream[/IMG]

Coroplast cover on ,ready for a interstate test...too much work!

[arcosine]

Yesterday's test drive was inconclusive due to the high wind, 22 gusting to 33 and large fox hunting antenna array on the car. There is defiantly a difference on how the car drives, I can feel the weight in the rear, it drives more like a sw1 (wagon). Cross wind stability is worse, much more so than with just the wheel skirts. The gusts blow the car around and a couple of times I had to fight to keep it in the lane at 65 mph. More testing today, but the winds are forecast to be stronger with gusts up to 40 mph. I need to fill in the inside of the rear wheel fairings,as they are open now. I might try some wind tunnel testing in the driveway. I was second place in the fox hunt. They said the back of the car looked like a front of a car.

... faired in the rear wheels and made a custom exhaust extension. Very windy today.

right rear wheel faired...


up on blocks...

riveting using mushrooming pop rivets from Mc master carr...

exhaust extension...

Need turn signal lights...
