Project: 395 Detroit Sled Dragger

Detroit 395
This is a build-up thread of sorts for my Clod.

In October of 2005, my parents and I went to our first ever NR/CTPA Worlds event. At that event, I was introduced to the Retro Monster Truck. I was amazed by the detail, and scale appearance of these trucks. About five weeks later, I had a Super Clod Buster sitting in front of me, ready for the journey I'm about to explain here, from AM/PM Rocket Retro to 395 Detroit Sled Dragger Box Stock.

I started with a stock Clod, and soon put all the goodies needed for the Retro class on it, hitch, servo mount, AM/PM Rocket custom airbrushed body, and so on. I ran it only at the 2006 Worlds before I decided racing is just not my thing, I'm going strictly pulling (again).

I then locked the diffs, upgraded to an ESC with 7 cell pack, and got it up to 14 LBS. The truck was not ready to pull until the night before its first big pull, the 2007 County Line Winter Super Pull. In round one, I hit the wall, Dairy Queen. Before round two, Spence gave me a driving tip that would help me rest of the weekend, so in round two, I took the sled out the door. With a full pull already, I passed third, and we went to the pull-off. I stupidly put an old, worn out, weak battery pack in for the pull-off. Because of this, I ran out of juice at about 16-20 feet, and finished about fifth out of six trucks. I then started preparing for the Spring Nationals, in May by fixing the front wheel drive that I lost at an undetermined time that weekend.

With weeks to go before the spring event, I was just starting to get the truck back together. With about three days left, the truck was back together, but the motors would not turn, the truck stayed home.

I have figured out the problem, and have fixed it. With the fixing of the Clod, I will now abandon my T-MAXX pulling class adventure in favor of Project 395 Detroit Sled Dragger.

Why 395 Detroit Sled Dragger? It is so named because of my favorite engine, the 6.5L GM/Detroit turbocharged diesel. The 6.5 started in the late '70's when GM went to their Detroit Diesel Division to design a new diesel engine, that would be much better than the old Olds 350's. They came up with the 6.2L natrually aspirated diesel engine, available in C/K pickups, Suburbans, and Blazers from 1982 until 1993. This engine was not much for power, unlike the modern diesels of today, but a milage vehicle that would go forever on a tank. Many years later, GM redisigned the 6.2 with a slightly larger displacement, 6.5L, or 395 CI. This new engine, available from 1992 until 2000, was available with or without a turbocharger. In 2001, the Isuzu/GM Duramax 6600 6.6L turbo diesel replaced the 6.5, and started GM into the high horsepower diesel world.

My goal is to make a fairly close to scale Clod with a scale model 6.5 under the hood. For this, I think I'll use a 454SS body from Parma, a Dodge Hemi kit from Parma, and an SCollins High-Lift interior kit. The hood will be hinged to reveal the engine, and various styrene sheet, rods, and tubes will be used to replicate the 6.5 as much as possible. I will update this thread as I build the 395 Detroit Sled Dragger.

Wow! This is gonna be good. You just don't see scale Clods anymore. Everyone's crawling. Get started. I can't wait for some :pics .

I have the pics, just need to resize them and host them. Right now, I've gone as far as I can without the engine. Hopefully, tomorrow, I can get the engine ordered, and start making it into a 6.5. Right now, only the turbo is done. It is a three piece assembly, consisting of a compressor wheel, turbine wheel, and air intake/turbo shaft. The compressor wheel is just a loop of styrene tubing, with a long outlet, to go to the inter/aftercooler. The 6.5's did not come with inter/aftercoolers, but I'm building this as an early 90's monster that was built with a 6.5, so that means performance. The turbine is just an upside down U that will act as a heat sheild mount, and turbine houseing. The last piece, the intake/turbo shaft has the intake tube from the airbox, and the other two pieces loop around it. I'm also planning on cutting the tell-tale holes in the bumper, and putting a scale remote mount injection pump driver in one. All the hoses will be styrene and brass wire, rod, tube. It's not going to be an exact model, but I will model the main, most obvious 6.5 features, like the intake (which will be backwards to accomidate IC), turbo, injection pump, aftermarket pump driver relocation (more about that later), turbo, and injector lines. I'm kind of nervous, as this is my first scale build, and I don't know what to expect. I hope it'll be done for the NR/CTPA World Championships this September.

All these full scale pics are from a '94 Silverado 1/2 ton.


Airbox.

Notice the holes in the bumper under each end of the grill, easiest way to tell a 6.5 diesel.

A crossview of the whole engine

Another way to tell the 6.5. Having these from the factory are very rare, I don't know if these are factory or not.

This area, between the engine and brake components, is where the model will have an intercooler.

If you look closely under that cover (that will not be on the model), you can see the injection pump.

In these vents you can see another view of the IP, and the intake right above it. The model intake will be reversed to hook into the intercooler, not turbo.

An overall view of the engine

Front view of the turbo

Here you can see the pass. side manifold, that the turbo mounts on.

Another tubo view

Model pics:


This is the whole turbo assembly.


This is just the airbox intake and turbo.


Turbine wheel.

Not much yet. Kind of hard to see the model turbo pics, with them still being white styrene.

Just got all the stuff ordered, should be here soon. I just realized the 454SS is a '91-'93 body, pre-electronic fuel injection, so no remote mount pump driver.

Well, everything from Tower came in today, all I need now is the stuff from Walthers, then I have everything. I'll start putting the engine together today sometime.

It's comming along nicely. The block and heads are painted and assembled. The lower intake is painted, assembled, and mounted. The upper intake is assembled and painted. The injection pump is painted and mounted. And the turbo is assembled and painted. I'm currently doing the painful task of putting the injector lines on it. I've changed my plans, because there isn't quite enough room in the Clod to put the inter/aftercooler in the hood, so I'll model it like there is an inter/aftercooler under the truck. I have some pics, and will put them up as soon as I'm not so busy.

Not really, other than the thin stuff for the turbo oil (haven't had the courage for this), and the injectors, the sheet is the biggest pain, but it's easier to hide the problems, and it'll still glue without being rubber banded together.

Can't wait to see the finished motor, let alone the truck. Sounds great so far :tmb. Lookin forward to more pics!

The project is on hold now. I have decided I do not have enough time, so I will put the project on hold. I may decide to build the engine and everything as a different truck, maybe not. Right now I don't know what I'll do. It may still be done for the worlds.

I've figured out some timing. I'm aiming to have the body/interior done before the Worlds, in Sept. I will, in the meantime work on the engine, and try to get it all together before the Winter Super Pull in Feb. or the Spring Nationals in May.

This is the first update in a while. I have come to the realization that the engine in the Clod will not work. I think I'll still put the body and interior on, but the engine will not go in. Being a puller, I have to have a ton of lead in the engine compartment. The only way around that would be to have the engine in during concours (where I wouldn't stand a chance anyways), and weight in the truck during pulling. I know many members would frown on this, and it may be illegal anyways.

I will keep updates on the 395 Sled Dragger here. I think the conversion will be complete befor the Winter Super Pull. The only change to the plan is to exclude the engine.

I'm currently looking into a different project for the engine. If I go along with this project, it'll get its own thread in the scale section.
