I masked off the intercooler and then blasted it. Not sure why I didn't get a picture of it after blasting...:hmm:



I also blasted the various machined areas of the intake manifold.









I also went around the whole intake and broke all of the hard corners with a file. It is amazing how sharp the machined edges can be.

All of this is in preparation for Cerakoating when the weather finally warms up a little.

An old oil pressure sensor was turned into a plug.



The lower MAP sensor was turned around and a new mounting hole was added for solid retention.



I decided on this fitting for the oil drain. It's stainless and it swivels. As long as it doesn't stick out too far, it should be good to go.



It is about 1.75" from the pan to the end of the fitting. The fact that it swivels will make it easier to fit the drain hose.



I removed the press in nipple off the passenger side valve cover and use a 1/8" NPT tap and added a stainless plug.



The injectors fit well with the rails and the intercooler brick. I will be able to route the injector wiring and the coil wiring together and run them back to the bulkheads that I showed before. These are Holley 120lb/hr, low impedance injectors.



This is an Earl's oil fill adapter that has an ORB fitting and it will go to the catch can.



Baby steps...

Andrew

Looks fantastic.

For coating intake pipes, what is your preference, Cerakote?

Andrew,
What diameter lines do you plan on running for the catch can? I don’t recall reading anything about which brand you plan on running. Have you researched this any or just going with a repeatable one?

I have Earl's Ultra Flex for the catch can. IT will be AN-10 from the valve cover to the catch can and AN-6 from the catch can to the back of the intake.

Well, that's good you've been really busy with the tuning!

Is most of it remote or in person?

​​​​​Vast majority is remote. I have a few local customers, but that's only by coincidence.

Thanks Andrew. Have you ever heard of anything bad about MightyMouse CC, either N/A or boosted/LSA SC?

It seems like an excellent product, which is why I got one.

Zero progress. April, May and June have been super busy and unseasonably hot. Doesn't make for a lot of motivation...

I wish that I was reporting some progress on my GTO, but the last 90 days have been crazy busy for me. I am no complaining, but it has dampened my enthusiasm on the GTO.

However, one of my customers is building a 57 Chevy, using the Hooker turbo manifolds, and a single BW S475. These are his pictures.















He too is using the Holley mid-mount accessory drive system, and his turbo placement is very similar, if not exactly how I want mine to be. Notice the brace that he added from the head to the turbo.

I think this is an excellent idea and something that I will be adding as well. The turbo is about 35-40 pounds and having it hang on the up-pipe without any support seemed like a bad idea to me.

I wonder if the turbo support will eventually crack being aluminum.

I believe it is stainless.
