Sure thing. I forgot to mention trans pressure.

The Tick Performance intercooler showed up yesterday. I was very impressed with their careful packaging.



This thing is absolutely gorgeous and is built really well. The intercooler core looks to be a high quality design with a high density of fins.



The mounting flanges are billet as are the end tanks.



I also received the V-band flange for the compressor discharge piping, which will be 4 inches in diameter.



This is the MAP sensor that I will be using. I will actually be using two of them. These are 3 bar, which is a little more than I need, but I don't like running sensors to the limits of their range.



There are 4 wires instead of 3, like you would find on a typical MAP sensor. These sensors have an integral air temperature sensor, which makes for nicer packaging. One sensor will go into the Low Ram intake base, while the other will go in the lid, above the intercooler. This will allow me to measure the pressure drop across the intercooler as well as the temperature change.

Nice parts.

That IC looks beautiful! That should work nicely for your goals. Now those sensors are slick. How do you find the data to populate Holley?

happy to see you decided on the intercooler. Coatings are looking great!

Ballinger motorsports sells the sensors and has the output data on their website.

I am a little curious to see how it all works out. I think I can go with a firewall mounted fill/burp tank, which will be the highest point in the system.

The weather is crappy again, but I try to get little projects done whenever I can. I showed the Earl's 4-port steam kit before, but the outlet tube that came with the Earl's kit wasn't going to work for me.

I decided to make my own little tube that goes directly to the nipple on the water pump casting. I got a roll of 1/4" NiCopp tubing and used an Earl's tubing straightener to make straight section of tube that was longer than what I needed.



I bent up some scrap at various simulated angles to give me an approximate angle.



I wanted the angles to match for better aesthetics.



This all seemed to work pretty well.

The Mighty Mouse Solutions timing pointer had to be shortened just a little bit in order to work with the ATI balancer that comes with the Holley mid-mount accessory drive.



To be honest, I am not sure that it will actually be visible when everything is assembled, but at least it is there and pointing accurately.



Then I noticed this...



Looks like its back to using the drain ports on the pan. I have a real short fitting that I will try.

Andrew, the steam lines look nice. You have joined the club for making hidden items as good as you can. Pics on forums have made it easier to join the club. Many items that were never thought about are now polished, plated, painted or something similar in places that only the builder knows about. (you may have already been a member and I didn't remember, no offence meant to your prior work)

Since all the cool kids on YouTube are using Send Cut Send, I wanted to give it a try. Unfortunately, I have zero 3D modeling skills. However, I have a friend who is a master modeler.

I want to use some Molex bulkhead connectors for the injectors and coil sub harnesses. Molex happens to have 3D models available for all of their connectors, which made Blakes job super straightforward. He drew this up in 30 minutes.



I uploaded the file, paid, and a week later I got these.



They are cut from 2mm aluminum plate, which makes them sturdy enough.



The connectors bolt in from the backside.



If anyone is interested in these, get in touch with me. I got extra because Send Cut Send has a minimum $ for each order.

Thank you. I appreciate the kind words.

Andrew, I love all the work you are doing. I've never heard of that company SendcutSend, but that is really cool. But that's probably because I'm not a cool kid haha.

Where will you locate those bulkheads? Are they intended to be waterproof? I like the attention to detail.

Thanks Clint.

I actually took the plate to the garage earlier today and kind of looked at where they might go. The bulkheads have an o-ring on the backside, so when they are screwed down against the panel they should seal nicely.

I am thinking they will fit perfectly here:



I will reroute the wiring for the wiper motor somewhere else. Maybe to the grommet just below, where my hand is covering some of it.








This is a picture from when we were taking the engine out. It gives you an idea of where the plate would go, just below the wiper motor.





These 3 connectors are not for the whole engine harness. The center connector is for the injectors and the smaller ones on the side are for the coils. The rest of the harness will pass through the big hole to the left, where the old harness is in the picture above.

Did a little more mock-up. I was a little worried about the coils and Accel wires playing nicely together with the turbo manifold.

Spark plug access is amazing, which is really nice for quick plug checks.



Cylinders 2 and 4.



Cylinders 6 and 8.



There is a solid 1/2" gap between the ceramic plug boots and the manifold runners.



Overall, this is looking promising. It remains to be seen how the downpipes will effect any of this.

Looking good.

[thumper877]

That is a awesome looking engine stand. The red matches your vavle covers lmao

amazed every time i look at this thread

Looking great Andrew!

It's a bit hard to tell from the photos, but are the plug wires a bit long? I had custom wires made by Kingsborne that came out perfect. https://www.kingsbornewires.com/
