Jamie at Moluminum has a resin C15 twin turbo, if that's what you mean.

I follow Matt/Diesel Creek on youtube and I will follow this too.

Wrong post

The AMT American LaFrance fire trucks has a Detroit Diesel 8V-71 and it looks like a Fuller transmission, I have no clue what speed it is, 9-10-13... The Trumpeter kit has no engine but the transmission looks like a Allison Automatic, not that uncommon in fire trucks. Keep in mind that the engine in the Revell snap kits is a Cat 3406A, it came 1973 and was a pre-combustion engine at first but later direct injection, it was replaced with the 3406B 1987, so it's quite old. The Revell snap kit 3406A engines doesn't have a aftercooler, just a plain intake manifold so it's a lower power engine, but the A model was available up to 425 hp and they had the aftercooler wich was water-to-air like the Cummins aftercoolers. The 3406B evolved to the C model 1993 wich was partly electronic and the latest version of the 3406 is the fully electronic E model from 1998 and after that the C15 took it's place in 1999-2000, Caterpillar left the truck market in 2008 and concentrated on construction equipment, marine and diesel generators. The difference between the A and B/C models is where the diesel injection pump is located, in the middle of the drivers side of the block lengthwise for the A model and near the front cover on the same side for the B/C model and the E model has no injection pump at all as it's fully electronic and the E model has 3 valve covers and looks more like a C15 than the B/C models but they are not of the same family.

Of course. It's your model and you are free to do as you please. I just wanted to share the information and you are welcome to it as all here are...we are here to help each other. Happy building

The A-925 426 DOHC engine, the engine that never ran under it's own power.

Turned out nice.

It helps to have some knowledge on how things on a car and truck works when you work on models to get things right. The pipe going over the engine top from the turbo to the intake manifold shouldn't be there if you have an air to air intercooler/aftercooler in front of the radiator. If you are replicating a truck from the mid 90's the engine you are using is too old, it's a Cat 3406A wich came 1973 and replaced the 1693, the A model was replaced with the 3406B in 1987 wich in turn was replaced with the 3406C in 1993, after that came the 3406E wich is the final version of the 3406 up to 2007 when the C15 came, the C and E model was produced at the same time for about 5 years as the C model ended production in 1998. The major difference between a A and B/C model is where the diesel injection pump is located, about mid engine block lengthwise for the A model and up against the front cover for the B and C models. The E model has 3 valve covers like the C15, and the A/B/C models had only 2, the E model was also electronic and has no injection pump on the side of the block. I don't think the 3406B and C model are available on the aftermarket, only the A but the C15 is wich is very similar to a 3406E, so for a mid 90's truck I would have used a 3406E/C15 engine for it. But it's your truck model and of course you do as you please with it.

Hmm, the turbo plumbing looks a bit weird. If you have a air to air intercooler in front of the radiator as you have plumbed you should loose the cross over pipe from the turbo to the intake manifold that goes over the front head, because you don't have both as that cross over pipe is the route from the compressor side of the turbo over to the intake manifold on a non air to air intercooled engine like this Cat 3406 engine originally is, it doesn't even have a water to air aftercooler that most of the higher horse power 3406 engines had.

I can agree with you in some of your reasoning Steve. The 3D printing is mostly better than the injection molded stuff when it comes to small details and lots of 3D prints are really very good, but I see the resin casters on the aftermarket will suffer of this a lot more than the model companies will and that's sad in my opinion because they do fill a void. So 3D printing will most likely kill the resin businesses long before they will ever touch the model companies. I find it hard to believe that 3D printing will be cheaper than injection molding when it comes to complete kits, one of the largest 3D priniting companies Shapeways who had state of the art machines went bankrupt recently...so I'm not so sure if I believe it ever will. The design stage in a CAD program takes the same time for 3D printed part as it does for a part in a tool for injection molding so that's a fact, and time is not free if you are going to earn any money, and therefore the designs will not be free either, so printing out a detailed part will allways cost money if you count everything in, just look at what the 3D printed stuff costs today where a 3D printed individual part costs 1-10 bucks and a complete engine almost costs like an injection molded kit, not far from it anyway. I don't think 3D printing will be much cheaper and faster in a forseeable future but it's for sure a good source for our hobby, and if you can do everything yourself, both the CAD design and the printing, it's a win as it only costs time and material...and of course the computer, the CAD program and 3D printer but that's a one time cost.

Very nice.

It's a thing I have noticed on pictures of real W900's, none that I have seen has the front wheel in the center of the wheel arch, they are allways slightly forward of the center line, so it's how they were made. But of course you are right, a custom truck is a custom truck and you can do what you want with it...like fix the off center position of the front wheels. 🙂

Yes you are right there, 3D printing has done much for the hobby so far and will probably do more in the future as nothing is impossible with this technique. But for real mass production it has a long way to go yet. But I wish I could use a CAD program and have a 3D printer myself...I have lots and lots of ideas on things I want to do.

Yes it's not the internal combustion engine that's wrong, it's the fuel it runs on. Sustainable fuel can come from many places, not just from agricultural sources, it will come but it just takes time to do it economically viable.

You blow us away Brian.
