The 911 is a classic shape and classic lines, I guess I'm sitting here scratching my head as to why you would pick a solid car to "rat out" in the first place, but it is your car.

I understand where you guys are coming from. Ya gotta understand though where I am coming from. I am a Porsche guy through and through. So I already have some pretty Porsches (see my intro). I don't really need another pretty car. But I do have this project and have very little money into this car. So I was thinking about doing something more raw and rough with this car, something fun and different from the other cars.

I appreciate the feedback and will start working on it WITH the front fenders on and see about adding a rat look to it in that form.
 
Maybe do it like a 930 slopenose that got used as a parts car by one of those arab billionaires. 100% perfect car parked outside in the sun for the last 25 years. Crappy oxidized paint and oxidized wheels

How about using round tubing and expanded metal to make the front and rear bumpers. You could also use expanded metal to cover the motor compartment. Expanded metal comes in a wide variety of sizes, the smaller stuff is pretty easy to work with and form. You could even fill in the vents and stuff with it.

Yup, yup, yup... that's what I'm really leaning towards now is putting the front fenders back on, but not the bumpers. I will then use rectangular tubing (less of a 4X4 look than round tubing IMHO) and expanded or perforated metal to make front and rear bumpers. I have been kicking around the idea of replacing the engine lid with it too, like you suggest.

Part of the issue is weight. I still want this car to perform well. I have dropped a lot of weight with removing some of this crap - at least 150 to 200 lbs. I just hate to pile a bunch more of it back on, so I am thinking more of making a simple and lighter weight bumper for the front and the rear.

My big project right now is eliminating the rear muffler (over 20 lbs), which will help to clean up the rear view of the engine with the rear bumper removed. The car's catalytic converter has been gutted out, so it's just a straight run for the exhaust and way too loud. I am making a custom, fiberglass wrapped baffle that will go inside the gutted catalytic converter. This way I can keep up the image of being legal with the cat installed, but convert it to acting like a muffler (which I can tune for sound).

Progress

Made some progress on my project. I just bought a welder and I cannot weld well, but I started with something that won't be seen. I built a baffle to allow me to eliminate my muffler, clean up the rear end, and drop some weight.

Without my muffler the exhaust is a straight run and too loud for extended drives. The catalytic converter is there, but was gutted by the previous owner. I like staying out of trouble, so I like at least having the semblance of a cat on the car, especially as it will be exposed with the rear bumper removed. Since it's gutted though I decided to build my own glass pack baffle like I've had on my motorcycles before. I then installed the baffle inside the gutted cat, which now is basically an expansion chamber and glass pack muffler. It quiets the exhaust down enough that it's bearable, but still nice and loud and obnoxious. :D What's nice too is that with the baffle I can adjust the sound level to my liking by either making more holes/removing packing or by adding packing.

Any down sides to this? I think a little back pressure is good for the engine, which this provides. I'm hoping it doesn't impede flow too much though and cause the engine to run hot.

More Progress

So, my plan is to eventually go with a two tone look as the interior is already black and white. I want to paint the hood, rear trunk, and roll bar covers all flat black and have the rest of the car flat white. I have a lot of body work to do though, the rear engine lid is a real mess. But... I got to thinking. I also have this project sitting in the shop:

75911S.jpg


It's a '75 911S field find that I have been slowly working on. I don't plan on really completing it for another year. It's got some really great, faded black paint on it. So I figured that I could just borrow the hood and engine lid for now to go on my '86 Carrera project. First I took the targa bar cover off the '86:

TargaBar.jpg


The old cover's thick white paint was peeling off in huge chunks. Fortunately a friend of mine had given me a black targa bar cover. It's been out in the sun way too long and has faded to a real flat black - perfect! I also cleaned up the peeling paint from the vents under the cover and painted them flat black. Here she is with the black cover and black rear engine lid:

And then the front:

FrontView.jpg


Note my little twist to the Porsche emblem on the hood. This is a great emblem too. Normally they are plated gold, but with lots of sun exposure they wear down to a faded silver look, again, perfect!

Borrowing these parts are a big deal to me as they have saved me a lot of time with body work and paint. So I can focus on other aspects of this project for now and go back to finishing these parts later.

Next, I need to get the rear wheels back on, then I want to weigh the car to see how much weight I've managed to drop with the bumper, AC, and muffler removal. I am expecting that the car will be down around 2,600 lbs. After that I'm going to work on fabricating the exhaust tip that will connect to the baffle/cat.

Exhaust Done

My factory is in the middle of an annual shutdown. Being gone to work 14 hours a day, including weekends, does not leave much time for work on the car. Last night though I stole an hour to get my exhaust finished up. I cleaned up the stock heat shield/skid plate and welded in the perforated metal cover for the round window that was used to access some test port on the cat. I used a U clamp to attach my own $7.50 exhaust tip. I may do something different in the future with the exhaust tip. I had wanted to drill a machine gun barrel design in the tip, but decided to keep it simple for now. My wife wants me to add the "Tailgunner" exhaust tip. :rolleyes: I thought a little support at the rear of the exhaust would be a good idea - hence the chain. All paint used is the 1200 F high temp header stuff. I may paint the cat silver later if that orange bothers me with the final aesthetic of the car. Overall I'm pretty pleased for now. I probably dropped 25 pounds off the car and it sounds pretty good.

Next I want to mock up the rear bumper pieces in wood. I also got some ideas for doing something different with the tail lights, which I had not planned on changing. I will probably explore those ideas further.

2013 First Update

Well, I made some good progress last weekend that I want to share. Things have been slow on my build as I was working on four other cars doing non-project regular maintenance and repair work (new fuel lines, mass air flow sensor, rewiring job, oil changes, etc.). So, I’ve been busy, just not busy working on my project. I got in a day and a half of work done though, so here’s my progress.

In the rear there is a red reflector that has “PORSCHE” text across it. One of the previous owners cut out the sheet metal behind the reflector and welded in a box where they mounted some lights. The lights weren’t hooked up though. I did some re-wiring and got them hooked up. Three sets of lights will come on with the headlights/marker lights. The other two sets will only come on with the brake lights. So it will kind of function like a running light/brake light combination. The bulbs are not double filament, so I had to set it up this way. Pictured are the lights that come on with the brake light.

Body Work Mostly Done

I got a lot of body work done, doing the final finish on some hole filling and surface rust/paint repairs. The big 1980’s style “flag” mirrors were removed, leaving behind four big holes on each door. I welded in plugs and have smoothed out the final surface. I have some nice, aerodynamic mirrors that will get mounted up now. The passenger side door is almost ready for paint.

I also found out that the door handles are anodized zinc pot metal – with several heavy layers of paint hiding them. I removed all of the paint and will run them unpainted unless a corrosion issue comes up.

What To Do With The Front Fenders?

Finally, I cleaned up the oil cooler piping just for fun to see what it would look like without grime all over it. It’s a combination of brass and copper piping.

Now I face a real dilemma that I’ve discussed on here before – leave the front fenders off or put them back on. I started mocking up the front bumper out of wood and need to make a call on this issue as the bumper will be different depending on the direction taken.

I think that with the fenders on the car will look like a cool 911 when done, but not much of a rat rod. With the fenders off I can leave the oil cooler pipes exposed. I would then use copper tubing as conduit to run wiring to the headlights and turn signals. Plus I could use some copper tubing in the rear for another project. This could give the car more of a steam punk/rat rod feel.

I’m more inclined to go the route of leaving the fenders off because I think this will give me the opportunity to be more creative on the exterior and interior and make the car a lot more interesting. The idea here is to consider the overall flow and continuity of the car. I think it needs to be consistent. Front fenders and a mild look in the front means I need to be mild in the rear and mostly stock on the interior. No front fenders in the front I think gives me the liberty to be more loose with what I do in the rear and interior, as long as the look is consistent. That last option sounds like a lot more fun to me and I have some great ideas that I would just hate to not follow up on… thoughts?

Can you post some side shot pics without the fenders?

I'll try to get the car out of the shop in the daylight to get some side shots.

Today I ordered the headlights that remind me of a WWII gas mask in Post #6 of this thread. It's my first big expense for this project, $355, ouch! I think I'm going to hold off on doing anything with the front bumper until those lights come in and then see how they would look with and without the front fenders. The design for the back bumper is pretty fixed, so I can start work on that... if it ever warms up. :p
 
Okay I went back and looked at your previous posts of the side-I should have done that to begin with-duh. The lights are cool! I still can't wrap my head around the no front fender look-I think it's because of the sudden stop right after the door. Maybe you could transition it with sheet metal from the door back around the tire-hope I'm making sense.
 
New Driving Lights

Finally got my driving lights ordered and then finished one today. Another is in process. These will mount in the front and will supplement the main headlights. The cylinders are junk air cooled 2.7L Porsche 911 units. The lights are Hella (I am very happy with the quality, the housings are forged aluminum, not plastic). The copper tubing replaced rubber vent tubes. The hardware is all stainless. My cost will be ~$50 per light. I will make mounting brackets to attach to the hardware once I finalize the exact mounting location. The wiring will run through copper tubing, like conduit.

I think this kind of reflects the look I am going for in my car - not a rusty, junky rat rod, but more industrial and mechanical with a bit of a steam punk feel.

Lots of progress on the 911 rat project, but no pictures to share for right now. I am getting closer and closer to being done for now and getting the car back on the road, although it will evolve over time and never really be "done".

I thought I'd share something else though - another Porsche. This one is a '72 914 that I've had for four years. Inspired by the rat-look.com website I decided to use a parts car I have to give it that Volks Rod, Hood Ride look this weekend. Took me about a day and cost me $19.69 out of pocket (for rope and brackets).

I have it!!

I have got the perfect idea for your ride. No front fenders. Metal front and rear bumpers like you said. Like 2x3 rectangle tubing. Individual bumpers for each side like the prowler. Then, the good stuff.... COPPER!!!

1 1/2 inch copper tubing underneath the front bumpers all the way. To kinda tie in the look of the steam punk and complete the front of the car. Then solder Ts into it for your light mounts. Theres even end caps. Copper is a little pricey but will look cool with a little petina and exposed solder. Just clear coat after a year or so when it looks good and old.
 
Really like what you are going for here. Makes me think of a '56 T-Bird i saw across an intersection. It was unrestored and rough.The only one i have ever seen in that condition. I wanted to jump out of my car and cheer! [cl
