Adam, glad to see you're driving it at last. Such a cool build!

I think I’m gonna try my hand at making aluminum exhaust. I’ve always been interested in it. It’s not a big cost and if it doesn’t work out down the road, I can just swap stainless in for the aluminum.

I think they'd look cool with an early VW type placement.

My only experience with AL exhaust was the son of my co-worker in KY. He melted a hole in it a few weeks after installing it. But he was running a drift car.

How was it set up? Header straight to aluminum tube? Was there a cat (Iím guessing not if it was a drift car). Iím thinking long tube header to flex coupler, then V band aluminum tube, then V-band to muffler. That should get me a solid 3í from the exhaust ports before Iím into aluminum.

Kenny (captain bondo) made an AL exhaust on his 245

Nothing new to add right now. Was traveling for work. Buddy of mine made me a solid copper shift knob. Time to get cracking with the copper accents. My favorite.

If I can just get these stupid Craigslist cheap a$$ Enkeis to hold air and NOT have to buy different wheels, exhaust will be next. Kind of excited. Making my own mufflers and all.

I painted some old "American racing" vintage wheels (inside) with Hammerite to try and solve a mystery air leak. Didn't work but I bet you might have access to something to coat the insides?

Got room underneath for a wave termination pre muffler? Like FF from Portland did.

That copper knob is stunning. Can't wait to see what you do with the accents.

I know where the leaks are at. Right where some (previous) knucklehead thought heíd try to weld up a crack. His welds were so dirty that itís leaking through the porosity. The problem Iím having is when I try to just partially dig out his weld and replace with my own Iím still getting his junk in my welds. I THINK I got the last of it. Dunk tank looked good. Iím gonna throw it on and see if it stays up.

I tried reading the article attached as to what the chamber does, but on my phone the pictures (figure references) donít align well and I almost fell asleep reading it. Iíll have to try again from a desktop later. Traveling back to VA soon for work. Iíll have plenty of plane time to take another peek.

When I saw the pic of your shift knob I thought it was a tip for your mig gun! Very cool!

So I read through the article on my desktop and it makes more sense, but I didnít see any calculations for how large the chamber is suposed to be.

Vizard's exhaust science article has been around for a while. I don't think the Sunbeam chamber has much to do with muffling, but rather acts like (what Vizard calls a) pressure wave termination box - allowing pressure wave termination past the collector, so that eventual downstream exhaust components (muffler, piping, tail pipe length, etc.) placement and muffler style don't negatively impact upstream exhaust tuning. All this, as Vizard would say, for more effective chamber exhaust scavenging, which in turn helps pump up the intake side of things. Back in the day when I first read the Super Chevy article I had the same question you did - how much 'volume' is required in the term box? I reached out to Vizard at that time (it's been 10-15 years) and got a polite, but obscure response that seemed to point to volume of each box (V8 - 2 needed for dual system) needed to be equal to the cubic inch displacement of the engine - which took up a lot of unavailable real estate. So I gave up on it.

Given what you've shown us so far -- seems your focus should be on a muffler design that creates the sound quality you want without objectionable drone or flow limitations.

Precision milling right there. New bolt pattern?

I had a pair of R rotors and calipers I canít get anyone to buy from me, so it looks like theyíll be going on an E30Mazon.

So, since I needed to replace the radiator anyway, I figure itís time to upgrade to the full width. That being said, I probably shouldíve measured a full width before I made the core support. So, I trimmed and fit, trimmed and fit. I got it in place, but I realized I have no idea how the full width radiator mounts so I started making my own. I made a pair of floating mounts then poured silicone around them to create custom fit isolators. Next on the problem list is the late model hard coolant ďtubeĒ that crosses behind the fan. The early timing cover doesnít have the bosses to mount it. I pulled the cap, rotor and backing plate so I could see down in there, then drilled and tapped it to add a spacer/bolt. I also sanded/powder coated the tube and brackets. No ďsexyĒ pics today.



Oh, I threaded the shifter stalk and added the copper shift knob.

Got the full width radiator in. Added a couple new lower mounts that didn’t exist. Threw in some copper hard lines. Eventually there’ll be more copper accents in the bay.



New radiator hoses and expansion tank are on my short list.

What are those clamps you are using to secure the hardline to the radiator hose?

Dimartinofab on IG, it was on his Lexus. Straight AL all the way from the header down, no cat and since he keeps the RPM's higher than most people would (drift car), it didn't last. But it sounded great when he had it.
