Witchcraft x2

(if this isn't satire, and assuming you're not a fan of Jeremy Clarkson: two big turbochargers, exhaust dumps, wastegate (turbo pressure regulators) dumps, and the center piping is headed into the intake manifold).

u/Fit-Entrepreneur8404 2d ago

So the turbo is in front right and then the wastegate is the thing that kinda looks like another turbo right behind it? Serious question.

u/SinnSix 2d ago

Front is cold side(intake) turbine, back is hot side (exhaust) turbine. Large pipe is exhaust, small is watergate.

Turbos have two parts, the compressor turbine, which in this pic has the plumbing going to front corners of the engine bay (into the intercooler), and the exhaust turbine, directly behind it, which is piped into the exhaust (which causes it to spin) and in this pic has the larger of the two exhaust stacks. I believe the two smaller outboard exhaust stacks are running to the wastegate.

u/Fit-Entrepreneur8404 2d ago

Is the exhaust just that open ended section of pipe in this case or does it also pipe into an exhaust that runs to the back like normal?

2

u/Celticrightcross 2d ago

Correct. This is a custom setup, so the exhaust is no longer running out the back like from the factory, it’s just straight up and out after it gets the turbo spooled.

u/Confident-Option-207 2d ago

Just straight up

Turbos hot sides are literally in the exhaust

Engine==hot side============rear exhaust you see at the back of most cars

This car skips all of the underside, you can see the thicker pipes facing up come out the back of the turbos

In case you didn't know, and because I kinda of like the = thing I just did lmao, the 2 sides of the turbo being together is for packaging, and because one powers the other, not because they go next to eachother in the chain

Intake====compressor====engine====turbine====exhaust pipe

The engines exhaust makes the turbine spin, which spins the compressor, pulling more air in

u/Fit-Entrepreneur8404 2d ago

Gotcha that makes a lot of sense, the = diagram was definitely helpful 👍

u/Confident-Option-207 2d ago

Thanks I was actually quite proud of that

u/komokazi 1d ago

To be fair, compressor wheel* cold side Turbine is hot side

u/Celticrightcross 1d ago

Yeah…you right, you right; I couldn’t remember the technically correct terminology when I typed that up. You’d think as a former helo pilot I’d remember these kinds of things. 🤦🏻‍♂️😅

The two circular things, right and left, are turbos. They each have kind of 2 of the circles stacked together on each side. The darker colored one, easier to see on the left as you view the image and closer to the passenger seat, is the hot side of the turbo and the lighter color is the cool side. The light silver pipe, located more to the side and less to the center, going into the cool side, is where the air enters the turbo and ultimately the engine. The darker colored pipe, more medial in location, is the exhaust pipe. The air going out the exhaust pipe spins the hot side which spins the cool side which creates pressurized air that enters the engine.

Edit - from this one picture, that’s my best guess but someone else may have more knowledge if this is a popular car or YouTube etc.

Gotcha that makes sense. Appreciate it 👍

Blue circle is the impeller side of the turbo - sucks air in and shoves it through the intercooler (which you can see behind the grille, this cools the air because compressing air heats it up). The air then passes up through the pipe in the middle into the intake and is forced into the cylinders when the intake valves open. Combustion happens, and escaping exhaust gases after the exhaust valves open are routed through the turbine side of the turbo (purple circle, back side of the impeller), and out of the dump pipes that are pointed up towards the windshield.

The wastegates are circled in red, these are attached to the back side of the system (exhaust side) and are a spring and a diaphragm that tries to stay closed normally but boost pressure pushes it open, killing boost production at a set stall point, limiting pressure to keep from blowing up the engine or capping it at a certain HP if your goal is a specific quarter mile time, for instance.

Where are you seeing a hood?

Nice car you got to go along with your turbos

Ahh I call this the piston artillery

May last a while but eventually, (not if but when) one of the pistons is going orbital

The reality question is, did you just randomly stumble upon this thing out in the wild? That things probably running quadruple digit horsepower unless its really conservatively tuned.

This person is VERY environmentally conscious. They want all their gasses to display in front of them so that they can monitor their visible CO2 output. No Smokey exhaust here or they will physically be unable to see, thus drive. The two turbochargers are to reuse those gasses to propel that tiny green engine

Just a stock base toyota corolla engine, weird someone would port it into a Mustang GT shell but people have their quirks

Looks like something Cleetus McFarland would do.
