Hook up a shop vac to that sander. Use a flexible hose long enough to let you move around the hood. You'll thank me later.

IG @gbrettin:
Knockdown, test fit and fill... Yup. Again. All the problem areas have subsided. Last time going through the rough grit on this. I can start working on wet sanding next.

-----------------------------

I know these posts are a bit repetitive; but, it'd rather show what actually goes into the actual mould making process.

Hotrods - The Dewalt has a little bag that has been catching 85% of the dust (which has been amazing). I just so happen to have a small shop vac at the shop. I'll hook that up!

Something to be said about the edges on the mould... I have the edges roughed out and will need to dedicate a ton of hours getting them perfect. I have been slowly building the edges up, specifically with tooling gel since it's hard AF.

It's getting there.

More sanding supplies


Test fit. Edgest will be built up.











More Sanding

I have the same DO sander. That bag doesn't catch chit. When I'm using mine. I duct tape my shop vac to it. It will also make your disks last longer too.

IG @gbrettin:
Needs 1 more day of cure because it's still cold here. The lines look great, no more pin holes and no more fiberglass patterns showing in the tooling gel. The perimeter needs to be cleaned up. No worries, I have a plan!---- *Runs off and makes plan*

Starting the Sunoco cowl 370z plug. Part B of my mould. Whipples and high rams rejoice!

-----------------------------------------------------------------

The mould looks to be coming to a close pretty soon so I'm ramping up on making a plug for the cowl. All the lessons I learned from the hood will be dumped into making the sunoco style cowl. The pictures below is me just roughing a mental idea out. I could draw it on paper with proper dimensions but I don't see the point. I need to visually feel out the lines to see how they make me feel.

I'm also going to make two rough plugs. The first one will be constructed from the items you see below. The second plug will be from my buddy's Mustang cowl. In all honesty, I really like the shape of the Mustang cowl so I want to give that a test first. I purchased expanding foam from Composite Envisions. The foam can be poured into the cowl portion of the hood and then I can cut/sand the foam down. Perhaps I can get out to the shop tonight and make that foam plug.

I'm in the design phase so any and all thoughts are welcome.

Dried(ing) tooling gel




Cowl construction

IG @gbrettin:

I plan on making two plugs. First one will be hand made and the second is a direct plug off a different hood. I'll see what works better soon. And guess what! Another coat (say it like DJ Khalid).

---------------

Nothing new that you guys don't already know (from my IG statement). I will say this though... I ALMOST thought about dumping my foaming compound directly into the carbon fiber cowl you see below. The foam has some of the same chemicals used to lay up carbon fiber. It would have etched into the cowl ruining his hood if I didn't pull ripcord.

I'll put some plastic down and then make a plug today.

IG @ gbrettin:
Made me a big ol' hot pocket. �� Hot pocket ��

I needed a less dense A B foam mix and more of it. Great Stuff to the rescue. .... A few cans later... This hot pocket has been filled. ��

Rusty

Which Great Stuff did you use? The triple expanding stuff. You have to be careful of. It WILL push things apart. Don't ask me on how I know.

Oh yeah, she was ready to burst at the seams. lol

I filled in some pockets with MORE great stuff.

Needs more duct tape.

Well that was a pretty significant fail... 😂

Plug v1 found its forever home.

Starting sand out properly.

-----------------------------------------------------

Ordered a few more parts from Motion Raceworks. I think I'm down to a ordering a driveshaft now, last major purchase I know of. Outside of that.... I think I have everything needed to make it run. If not, the parts store has the rest.

IG@gbrettin:
Motion Raceworks coming through with quick shipping and notifications to my cell. FedEx guy is super excited about my build after frequently making stops to my house too. ��

Perfect fit with OE exhaust manifold, Firecore plugs, Motion Raceworks coil mounts, MS3 IGN-1A coil packs. I must say, the Motion Raceworks billet valve breathers are damn nice too

These Black Sheep Industries cold side clamps look like the business. Can't wait to get them welded up.

Guide coat, aka white spray paint, is showing me high/low spots. Only have a few problem areas left near the front. Don't mind the white strips near the center. I need to do those sections by hand.

--------------------------------------

For some reason I didn't get pictures of all the stainless steel, BOV, Wastegates and boots. All my boost components are in. My buddies, Dave and Nick, are getting a few major projects out the door. I suspect we will start welding a few things up in short order. Heck.. I might just start tacking some piping together. Hmmmm. Yeah I'll do that.

I was going to use a coupler boot, 4in to 3in, but have decided to go with a coldside clamp off the throttle bodies. Honestly, I don't like the look of rubber couplers. I'll need to find an aluminum reducer from 4 to 3 and order two more vbands (same Black Sheep Industries).

I have most all of the fuel components and AN cooling lines... so I will be getting that figured out as well (parts trickling in for those items make me feel not as bad about spending 20 bucks on a single fitting).

madwi

What a good looking build. Cant wait to see and hear this thing.

IG:@gbrettin

Needed a quick and easy win. Had these laying around for.... Three years. Old covers were a bit fatigued and I broke them .... Or at least that's the story I'm going with.

-----------------------------------------------

I did some work on my hood mould last night but didn't post it to IG... heh. I'll post the pictures here because I feel like torturing your eyeballs. I worked the corners of the mould and see that I can get the mould very close to OE; however, my buddy Nick and I came up with the idea to remould the corners back in. This will allow me to build up a defined lip on the mould and build up a nice transition to the flange. To implement that I will need to sand down the edges close, which that's what I am doing now anyhow. I'll prep the hood with release agent and PVA on the corners. Then I will build up around the edges with tooling gel a few times. You've seen how hard that stuff gets.

Update on the cowl plug. I'm pretty dead set on using Dave's Mustang cowl and modifying that. I ordered a few cans of 4lb density foam filler for the Sunoco cowl. What I am going to do different this time is build up a nice cardboard backer again and strap it on similar to what I did last time. What is going to be different is that I will lay the hood flat and pour smaller amounts of the 4lb density foam in. The cardboard backing will have a few relief holes. That will allow the foam to breath a bit and flow out as needed. Less tape will be abused on this cardboard backer.

Pulling the outer pillar cover was slightly disappointing. I wanted to keep the OE covers around. I was going to get a panel pulling tool... NAH, I went beast mode and pulled it straight back like an ape. I guess I'm not that disappointed. lol

Lastly, I ordered two more 4in vbands, 4 to 3in reducer and a few fragola fittings. Now if you have never ordered AN style fitting... let me be the first to tell you.... those little MF'ers can cost as much as a major component on a build when you tally up all of them. Brother vband must be related to the AN's because that is just about the same type of d1ck kick.

-- EDIT

The window stickers "the370z.com" is coming down in favor of my car sponsor "MS3Pro". Sorry the370z.com, you been good.... but I like discounted parts better.
