1969 Plymouth Roadrunner pro charged

[duffy-duck21]

Hello everybody!!

Already during the assembly of the Charger I thought about, which will be my next project.

As a Mopar lover, I opted for another of my favorite muscle cars: the 1969 Plymouth Roadrunner. 
At the moment, it is quite cheap in the bay. My copy of Autoworld I got for 50 euros (new and from the dealer).

Strangely, there are also versions that are significantly more expensive and only appear higher-quality at first glance. 
For example a metallic blue in the civilian street version costs 150 euros and it is the same quality in all areas.

And there I am already on the subject: in direct comparison with the Autoworld 1968 Dodge Charger, the Roadrunner can not compete in any way. 
EVERYTHING is much worse: bad paint, orphaned interior, boot reminds me somehow of Lego, engine room very easily implemented, etc.

But the quality is rather secondary, because it is completely rebuilt like my last project. 
The engine using this time will be a pro charged Hemi.

In the next few days and weeks I will upload different pictures of the building.

Here are the pictures of the original vehicle:

I can't wait to see what you do with this-I'm a mopar freak and i'll be watching !!!

Interesting looking starting point. The trunk (boot) hinges look like this may be a Die Cast kit. Has a nicely detailed engine to work with.

I start with the engine on the new project ... I just enjoy it the most.

Since my english is not the best i will show more pictures.

Basis is a dragster Hemi from GMP:

The exhaust pipes are made of 3mm Tiffany solder. To fix them on the cylinder heads, holes were drilled and 1mm brass pins used.

The base plate of the exhaust pipes was made of 0.5mm polystyrene:

The pulleys come partly from the GMP engine, partly I have taken pulleys from the leftovers and partly built by myself. 
The drive belt also comes from the GMP engine.

The Pro Charger looks almost exactly like a turbocharger housing. That's why I built it like the turbos on the Dodge Charger.
The housing consists of 3mm fitting solder. To get an even rounding, I used a 6mm drill as a "template".
The back consists of a base plate and a gear housing. Both made of polystyrene.
The screw connections of the back I have shown with M0.6 screws. 
Intake funnel and tail are made of brass tubes.
On the back, a piece of brass tube was used as an adapter in the middle. The three white struts are for attachment to the engine.

Next is the construction of the air intake. The housing consists of 4 parts polystyrene.
To get the air into the combustion chambers, the base was made of polystyrene.
After a long grinding, the air inlet was ready for the primer. The color was not that important. 
The main thing is the surface is nice smooth and shiny for the carbon decals.

The cylinder heads have also received on the top and bottom of the small M0.6 screws.

To see how small the screws are, I put a cotton swab next to it.

The base plates of the air intake pipes were then equipped with the 0.6mm screws.

Subsequently, the air pipes were painted in polished aluminum and the air intake housing attached.

The Pro Charger had time to dry overnight and was installed today. The throttle valve unit was also mounted to the air intake housing (again with M0.6 screws). 
The hose clamps consist of a strip of insulating tape, bare metal foil and wire.

Absolutely amazing-wow-!!!

Looking great so far

Amazing! how did you get the carbon fiber look?

I`m using decal foil from Belkits, Softer and top coat from MrHobby.

After the fourth start and 3 evenings, the manifolds are now under the cylinder heads.

The procedure or materials are the same as for the Viper engine: 
the pipes consist of 3mm fitting solder and the collector of a wire end ferrule. 
I'm not completely satisfied with the result, but everything stays that way now.

 

[duffy-duck21]

Also made were the radiator and intercooler. The Pro-Charger can be driven with or without intercooler. 
But just the option to cool down makes it very interesting compared to the supercharger.

Here, too, I made use of my experience of the Viper engine during construction: 
polystyrene plates, Evergreen ribbed plate and, as always, a lot of sanding.

Very interesting, very good work. What scale is this? 

[duffy-duck21]

The engine has largely finished today. 
I have built a new ignition coil including cables. 
The ignition plugs are made of insulating tape (so it does not come loose: apply a small amount of superglue on the ends).

 

[duffy-duck21]

The valve covers are from the original engine. 
Above the valve covers, fuel rails made of carbon were mounted. 
The matching A / N fittings will be installed a little later.

 

[duffy-duck21]

Here are also small progress again.
The chassis was lowered street-legal (rims are not the final version). It is lowered by 6 mm. 
More was not possible because of the front suspension, otherwise they drag over the ground. 
The front and rear axles are still bolted to the original mounting points and thus no wild glutinous is necessary.
Here's the comparison before and after:

On the underbody, the gray tank was repainted in aluminum and the rest painted in black silk matt (in the original it was glossy):

 

[duffy-duck21]

The engine bay has been completely redesigned. The original looked very modest and poorly made.
The sidewalls were cleared of the battery holder and the fountain solution tank. Then everything was sanded smooth and covered with 0.5 mm polystyrene plates. 
Finally, the areas of the strut tower were also made from polystyrene. In the middle there was an M1.2 thread:

Fascinating fabrication.
