1970 GTO Version 3.0

[andrewb70]

That’s awesome. Great idea.

Thanks!

Looks great Andrew,
So are you thinking a flat clear plate mounted on the bottom side?
If they gave you the CAD file for the printed part I could build a couple center concepts in Solidworks for you if you want.

I was thinking the acrylic would not be a simple flat plate. As I understand it, acrylic can be machined similar to Delrin. So my idea was to have the top profile follow the lines of the hood and have my business logo engraves on the underside. PM headed your way...

I really like that idea Andrew! That insert looks fantastic even for a trial fit.

Thanks Ryan!

It has been a while since I have made progress on the GTO. Over the weekend I was hanging out with a friend of mine from Chicago and he was busting my balls about not having done already. He isn't wrong.

The mailman dropped off the new Tick Performance one piece o-ring for their intercooler (they also fit Holley HiRam and LoRam intakes) this morning, so it was the perfect opportunity to do something productive.



The intake lid is on for good now.



Over the winter I also ordered these grommets from SpearTech. I was going to do something fancy, but I think I am going to keep it simple.



Apparently I robbed the silicone coupler and clamps for the Cougar :facepalm:



I was going to do fancy stuff with the harness, but I am going to keep it simple. I really want this thing running and driving before the summer.

Haven’t seen this in a while. Sick Andrew!!

[wfo guy]

Andrew, lack of time, lack of funds, lack of enthusiasm???? I believe you are quite a bit younger than me but to have 2 projects going plus the side work is certainly wearing. To make good planning to cover all of the bases is an art. In my case, the cold weather sucks the life from me. I'm so ready for summer again.

Andrew, what's the metal insulation you have on the firewall and the turbo exhaust, you probably already mentioned it tho,

[thedugan]

I think it's from DEI. They also now make it in black.

The stuff on the firewall is this:

The downpipe was done by Header Shield. It is custom Inconel cladding with a ceramic barrier between the pipe and the cladding. It is formed and welded in place.

Clearly, I have been neglecting this thread. We have had a busy spring and summer. My wife and I moved to Denton Texas and I have been busy with my tuning business and with the new house. I finally have all of my garage stuff moved down here and the new space will be a lot better than I have ever had. It isn't a 60x40 shop, but it will be comfortable. The GTO has been parked in that space for a while and the Cougar is still in storage locally.

I did not have a car at LS Fest, but that gave me the opportunity to hang out and enjoy time with old friends and make new friends. This is just a portion of the gang that meets up at LS Fest.



This LS Fest I was also working. I was in the TurboLamik booth promoting my remote tuning business as well as talking to people about the ZF8HP transmission swaps using the TurboLamik TCU.



The TurboLamik guys came to visit from Poland and here we are with their US distributor. (from left to right: me, Lukas Lamik, Greg Drozd, Agnes Lamik, David Lamik)



We had two cars there with the ZF8HP swap. They happened to run their best passes for the weekend lined up against each other.



Here is the time slip for that pass. Not bad for true street cars



Needless to say, after having experienced cars with the ZF8HP transmission, there was no way I was keeping the 4L80e in my GTO.

My Alabama buddies scored this big boy 8HP90 and it will be making its way under my GTO this fall.











If anyone is interested in learning about the ZF8HP swap, shoot me an email: projectgattago at gmail dot com

Glad to see you still plugging away!

[andrewb70]

Glad to see you still plugging away!

Absolutely. Once the garage is organized, I am going to make a conscious effort to make progress every week.

Once the garage is organized

I've been chasing that goal for years! One day.......

[andrewb70]

As time passes, companies improve and refine their products. Such is the case with the Tick Performance intercooler brick. Originally I had purchased their first design, but they have since released their Ultra Low intercooler and this is the way I decided to go.



The Ultra Low intake has an integrated billet lid that reduces the overall height by 2 inches compared to their original intercooler and a Holley top.



Not only is the intake lower, but the throttle body mounting flange is also moved back, substantially, which generally improves fitment.



With the lower intake, now there is ample room to reuse the shaker scoop. The shaker scoop is such a unique feature of this build, that I really do not want to change it.




With the hood closed, you can see how much clearance there is now between the top of the intake and the bottom of the hood. As you might recall, that clearance was barely 1/4" with the other intake set-up.



With the shaker scoop resting on the intake and the hood closed there is now ample room to make a mount that will attach the shaker to the engine.



With the throttle body now in a different location, the tube from the compressor outlet to the throttle body will need to be remade. I have been following Jon Volk's builds for years and he has inspired me to push the envelope.

I am using the Einstar 3D scanner to generate a 3D model which will then be used to designed the intake charge tube. The plan is to manufacture the intake charge tube by having it 3D printed from aluminum. I used foot powder spray on the engine to eliminate the shine, as the 3D scanners don't work well on shiny surfaces.



Here is the resulting scan.



Progress is being made...

[Larry Callahan]

That's a work of art!

[wfo guy]

Tech is a tool and with any tool, the better you become accustomed to it, the better the outcome. I understand what you said about pushing the envelope but having creativity or another pair of eyes does make a difference. Sometimes copying is the only answer. I like the hood scoop also.

[andrewb70]

The new intake tube is in the design phase and it is looking pretty good.

A few months back I started working with HPR Tuning. They are a company that make various accessories for the 8HP transmissions. I told them that an adapter for the transmission cooler lines with a thermostat would be a real problem solver. So through a series of iterations and my input they finally have a product. It was also made in collaboration with Improved Racing.




This part bolts to the side of the transmission after removing the threaded inserts.



The thermostat starts to open at 160 degrees F and targets 165F as a stable point, with the benefit of quicker fluid warm-up.



The o-rings seal against the ports on the transmission.



The inlet and outlet ports are AN-8. They are in stock on the Improved Racing website.

Here are some progress pictures of the intake pipe.

Like I said on Instagram, that 3d scanning and intake tube is next level! Really nice transmission thermostat piece too.

Thanks!

We are getting there!
























The next step is to get a prototype printed in PLA to confirm fitment.

Andrew

[ryeguy2006a]

That's so freaking cool.

[andrewb70]

That's so freaking cool.

Thanks Ryan!

A generous fillet was added around the BOV mount and here is the final part:



I ordered a prototype printed in PLA and it was less than $100 shipped. The aluminum part should come in under $600.

Gotta love technology!
