Looks great, thanks for hooking my TA up

Pleasure working with you and thank you for your business!

With the power levels that I hope to be making, I no longer felt that my 12 bolt was adequate. I shopped around and settled on Quick Performance from Aimes, Iowa. Their sales person was great on the phone and went over every detail. So I placed my order for one of their custom 9" rear ends.

I just received the housing with the rest to follow. I got mine with the small GM ends so I can retain my 4th Gen Camaro brakes. It is also 1" narrower overall, which will allow me to retain my wheels and run the 305/40-18 drag radials that I want to run.



The housing is built out of extra thick material, has a back brace (this might mess up the ridetech sway bar mounts...deal with that later), has a fill and drain port, etc...



The rubber bushings will be replaced with the R-joints that I already installed in the 12 bolt.



If anyone is interested in my 12 bolt, please feel free to reach out.

Wow, that housing looks MUCH nicer than the 9" I bought from them back in the day!! They've stepped their game up big time.

This isn't their standard housing. This is the one with all the bell, whistles and glitter.

Booooo, no turbo size comparison is official unless it's next to a Mountain Dew can. Nice parts collection so far. The bronze Cerakote should look killer. Good call on the 9" rear too. It didn't take long for my perfectly quiet 12 bolt to start whining after a few blast on drag radials.

What rear gear are you going for?
What are you using for a heat exchanger?

The rear carrier is a Yukon aluminum bolt through design with a Eaton TruTrac and 3.25 gears.

I skimped out a little on the heat exchanger and got one of the universal units from frozen boost. I got this one:

Vic has been making progress on getting the heat exchanger, fans, and condenser mounted to the radiator.






I also mocked up the CWA150 pump against the fan shroud and it looks like it will fit nicely in the location where the Volt used to have a similar pump.












The CWA150 pump is a little smaller in diameter than the cradle, but I think a little 3D printed cradle will make up the difference nicely and will allow me to offset the pump off to the side a little.

Very nice Andrew! Those radiator tabs are a really nice touch.

[andrewb70]

To keep engine bay temperatures down and to help the turbo retain heat, I got these turbo and waste gate blankets from Funk Motorsports in the UK. They look great and fit very well.

It's all looking good Andrew. Have you ever seen the hot side of the turbo ceramic coated then use the cover, or would that keep in too much heat and damage it?

The best option is to have the whole hotside covered with inconel. This however is very expensive. You can see examples of that on this build:

I am not George Poteet, so that's a little out of my budget. So I am doing what I can afford, which is cerakote and then I will wrap the manifolds and the downpipes. Retaining heat in the turbo hotside is beneficial for turbo response. This is also why I run cast iron manifolds as they can withstand the heat very well.

That stuff is so neat and priced accordingly.

Yes Sir! I believe they did the shielding on the Rad Rides wagon that I posted a link to above.

Today was almost 70 degrees and I couldn't let this day pass by. This project isn't going to get done by itself. So I went to Harbor Freight and got a new air compressor after realizing that my old one has seized up. Got a new hose, some fittings, and a few odds and ends and went work. I asked if they had "bailing wire" and the girl looked at me like I was crazy. Then I described what it was and she said, we have this...Apparently now days bailing wire is called "mechanics wire" and it is stainless. Who knew...



The in between pictures didn't turn out so good because of the bright sunshine, but here are the pictures after 6 hours when I brought them into the house.









I am really happy with how everything turned out. Like, really happy!

Lookin' good Andrew!

Home Depot. Get the rebar tying wire. Easy to work with and cut.

[SSLance]

Those look great Andrew!

[andrewb70]

Those look great Andrew!

Thanks Lance. I am on a roll. This morning I blasted the oilpan, turbine housing and the compressor cover. They are currently baking in the Weber.

Andrew

[andrewb70]

I couldn't let this string of warm days go to waste, so this morning I went to Vic's house again. He was once again kind enough to let me use his blast cabinet to prep the oil pan, turbine housing, and the compressor cover.

Both the turbine housing and the compressor cover have machined surfaces that needed to be masked off. Here is the exhaust housing before blasting.



This is the compressor housing after blasting. I also blasted the oil pan and then washed it in his solvent tank.



Then into the Weber they went for an hour at 500 degrees.



When I ordered the sample pack from Cerakote, I got burnt bronze, glacier black and glacier titanium. So I wanted to try those colors. I chose glacier black for the turbine housing. Here is it right after I sprayed it.



After having some time to dry, it is settling into a very nice, rich black with an eggshell sheen.

This is the glacier titanium. It is a little boring and I don't think I would use it on anything else. The main reason for doing the pan was so that it wouldn't instantly get dirty as base aluminum castings tend to do.



I have more burnt bronze and glacier black on order. The compressor housing will be burnt bronze as will the lower and upper parts of the Holley intake manifold. The Tick intercooler in between the upper and lower will be glacier black.

That stuff looks good! How durable is it in an automotive application?

Supposedly very tough!

[andrewb70]

Here is the turbine housing after it had dried overnight. I really like the sheen. This is the Glacier Black.



This is the glacier titanium after it has dried. It basically looks like cast aluminum






Today I also received the Circle D converter. It is the triple disk, billet converter.






I also got their billet steel flex plate, just to make sure.
