Thanks Pete!

I have never seen a NW throttle body with dual o-ring coupler. Link?

Andrew

 

I couldn’t find a link either, but I sent them an email asking about it and was told they make one.

 

Maybe it is a special order part?

The aluminum part has been ordered, so it's a little late anyway. The silicone coupler will look nice with the Murray clamps.

Andrew

 

I just found out about it yesterday, as I’m still toying with the idea of switching my setup to DBW. There is just much more you can do with DBW vs DBC, that it really intriguing to me, even though I have a dedicated race car.

 

I always encourage my customers to use DBW throttle whenever possible.

While the intake pipe is being made, I had my friend Blake design me another little part. He then printed some prototypes on his home 3D printer.



These are mounts for the fuel rails. They will be printed out of stainless steel.



Here is bracket that came with the intake manifold kit.

“Printed out of stainless steel”

I didn’t know you could 3D print aluminum. Now you’re telling me you can 3D print Stainless Steel?

Technology is moving so much faster than I am…lol

 

You can print aluminum, stainless steel, titanium, inconel. We live in amazing times.

Andrew

 

Do you need a special kind of printer for that or should any printer be able to do that?

 

The process is called Direct Metal Laser Sintering. The process takes place in a chamber filled with an inert gas. A powder metal layer of 0.05mm is deposited on the bed and a laser welds each layer to the one below. There are a ton of videos on YouTube.

The 8HP90 that I picked up had a mystery converter in it. It didn't look stock and frankly I didn't trust it. So I called up Circle D and had a discussion about my requirements. Here is what they suggested:



This is their hybrid 8HP90 converter. Externally it is the same size as the 8HP70 converter, which is 1/2" smaller in diameter than a stock 90 converter, but internally it is built to work with the 8HP90 transmission.

Here you can also see the Domiworks bellhousing adapter.



and the Domiworks converter adapter.

I had a little care package delivered today. Here are the fuel rail brackets, printed in stainless steel.






Tomorrow I will drill and tap as needed and maybe run the sides over some emery cloth on a granite block.

Andrew

 

That is cool as hell. Makes me want to buy a cheap 3D scanner and learn how to design parts in Solidworks!

 

I used a bench-top drill press and a step drill to open up the holes on the front and on the bottom.







Here they are mounted to the intake and holding up the fuel rails.

Here is the final raw, 3D printed aluminum charge pipe:

I'm picturing a lot of different ways you could paint the finished part to highlight your logo on it. Curious to see what direction you choose.

 

I was thinking about using the burnt bronze Cerakote and then lightly sanding on the raised logo. I'm open to suggestions.

I ran across some videos by Devin Vanderhoof. It seems that he too has discovered the Hardwire Electronics PDM products. In fact, he has become the biggest distributor in the US for Hardwire. As you may recall, I already have a PDM 25 under the dash, but after seeing the videos for the new PDM 28, I knew that's what I needed in the GTO. I will use the PDM 25 in the Cougar or the Suburban.

Here is the PDM 28 as it arrived.



The size of the PDM 28 is substantial. Here you can see it compared to the Holley Dominator ECU. They are roughly the same size.

The reason for choosing the new PDM 28 is that it has two CAN busses. With the release of the Holly CAN documentation, the PDM 28 is fully compatible with Holley EFI.



Holley had a 3D model of the Dominator available for download.



An email to Hardwire provided the 3D model of the PDM 28.



I once again used my Shining 3D Einstar 3D scanner and generated a scan of the GTO dash and glove box area.


The plan is to design a mounting system for the Dominator and the PDM in the area that used to be occupied by the glove box.

Andrew

 

This thread is ridiculously cool. I worked closely with 3d scanning and have a keen interest, 3d printing metal as well.

Keep it coming

 

I've been wanting to rewire my car and one of those pdms are tempting
