Jesus, this really puts into perspective just how insane JP's alien biology is to withstand that insane acceleration AND his skill in driving that beast in such a way that he's not vaporized into red mist
I learned while making this beast that I can add the line: *_primary_length: 25 * units.inch,_* in the add_cylinder() parameters when creating each cylinder bank, and put different lengths on each cylinder to make unequal length runners for each header. So this had a gradient of 15, 25, 35, 45, 55 and 65 inch long runners before the collector from front to back on the right and back to front on the left bank, and it actually has four collectors total and four headers as cylinders 1, 2 and 4 in each bank are one pair of headers and 3, 5 and 6 are the other pair. It makes it sound less like an F1 screaming and more like a muscle car roaring so I'm glad you liked it!
beautiful sound, reminds me more of the yellow line engine though, would it be possible possible to get it to crank the revs up to something like 16,000 or more for the sort of f1 sound heard in red line?
If my computer could handle a sim frequency of 10000 Hz with a giant v12, then it could, but the current frequency is really pushing it hard. You can see the RT/DT going over 90 at a few points, and even at about 6200-6300 Hz the In Buffer shot into the orange and the sound got very choppy. It could rev higher as is, but it runs the risk of the simulation just breaking into infinity, and that's a certain thing to happen if I let off the throttle too fast, more frequency would let me rev higher than it does now but at the cost of me having to run in slow-motion to see it smoothly or dealing with choppy audio. Now, with the new version of the simulator, 0.1.14a, the RT/DT of the Airmaster went down from about 80-something to about 63 or so, so I might make a Version Two soon.
@@Avetho forgot to get back on this, since i made the original comment i've upgraded my pc, and tried running the sim at higher frequencies. The engine does not sound like a formula 1 at 16k rpm, but i managed to get the frequency high enough to hit 25000 rpm, which was getting close to the territory. To be honest I'm half certain this design would only start sounding like it did in redline at around 30000-35000 rpm, which kinda makes sense given the ridiculous power being put through the car in the movie.
@@Alto_C If I was awake enough to do the maths, I could probably tell you just how many hundreds to thousands of Gs those poor, poor conrods and pistons are suffering from. Truly, they're made of Redlinium, a superior form of metamaterial to Unobtanium since it exists. Frankly, I'd be the first in-universe to go up to any potential Supergrass embassy, holding a sign with the maths on it, and just say "Thanks, Supergrass!" and leave without further elaboration XD
It could be, but there isn't much material to go on. Technically, the TRZ Airmaster should be a huge radial engine with I believe 90mm bores and enough cylinders to displace 2000 cubic inches, though I don't know if 2000 CUI is reasonable or not, but the Airmaster is also something called a Motorjet, hence it having an afterburning turbine exhaust and a thrust-vectored variable-geometry convergent-divergent thrust nozzle, which is basically required for it to even provide the kinds of rocket thrust on Nitro which JP needed to do something like spinning the Trans Am so fast and with such a burst of speed and thrust it skipped across a lake on Roboworld like a stone thrown by a professional skipper. The previous engine was likely a huge V8 or V12 engine with a giant supercharger, as seen by the Yellowline Trans Am engine sticking part way out of the bonnet, and it made a little over half the power of the Airmaster, I read somewhere that the Yellowline Trans Am had to make around 20k horsepower, while the Airmaster is a complete monster in comparison at 35k, and somewhere else I read that the Gold Nitro had to boost power by like 10 times just to achieve the speeds shown if taken literally and not dramatized, meaning the Airmaster on Gold Nitro was making 350k horsepower, and on the Steamlight it could've been 10 times even that. Honestly, if that's all true, then JP, Sonoshee and Machinehead were well into the hypersonic range going up the Redline Mothership's spine to the finish line, its little wonder they were pressed into the seat not just from the acceleration force that got them going that fast and going faster, but also from the downward force that the ramp was making them feel as they pitched upward higher and higher. Then, its little wonder JP and Sonoshee got so much airtime after the Trans Am exploded, enough to nearly hanky panky while in the air, going so fast and protected by Redline's Supergrass magic aura from the hypersonic wind forces would've sent them halfway to the vacuum of space! The maths are bloody insane, but it only makes the movie that much more awesome to someone like me! XD
I don't really know which engine I took the firing order from. This is a V12 engine, and so long as my memory isn't being faulty again, this should be the firing order of a Rolls-Royce Merlin engine. I slow down the simulation in the video, so stepping frame-by-frame with the period and comma keys on your keyboard you can see which cylinder is firing next, and for reference the cylinders are numbered 1 through 6 on the right side, starting with 1 at the bottom of the firing order graphic in the top-right, while the left are likewise numbered 7 through 12. And the code for the wire connections in the engine file is this: .connect_wire(wires.wire1, (0.0 / 12.0) * cycle) .connect_wire(wires.wire2, (8.0 / 12.0) * cycle) .connect_wire(wires.wire3, (4.0 / 12.0) * cycle) .connect_wire(wires.wire4, (10.0 / 12.0) * cycle) .connect_wire(wires.wire5, (2.0 / 12.0) * cycle) .connect_wire(wires.wire6, (6.0 / 12.0) * cycle) .connect_wire(wires.wire7, (7.0 / 12.0) * cycle) .connect_wire(wires.wire8, (3.0 / 12.0) * cycle) .connect_wire(wires.wire9, (11.0 / 12.0) * cycle) .connect_wire(wires.wire10, (5.0 / 12.0) * cycle) .connect_wire(wires.wire11, (9.0 / 12.0) * cycle) .connect_wire(wires.wire12, (1.0 / 12.0) * cycle); So the first from the bottom on the right aka 1R, then 6L, 5R, 2L, 3R, 4L, 6R, 1L, 2R, 5L, 4R and last 3L. Its a relatively even firing order, opposite ends of the engine and opposite banks, so in theory this would minimize vibrations as much as possible, which may well be a lost cause for an engine that makes a couple tens of thousands of HP at the crank. Also, just decided to look up the firing order of a Merlin after typing this, and a Merlin acts more like two V6 engines back to front evenly firing one after the other. The Rolls Royce Griffon is also different to the Merlin and to this engine.

Love the sound of this monster

The Bocchi Pink Yellow Blue scheme has caught you too, huh?
Now make a bore-d out crossplane V8 version
Is it possible to make the engine from the yellow line race?

What is the firing order? The same as a regular v16? Or is it different
I don't really know which engine I took the firing order from. This is a V12 engine, and so long as my memory isn't being faulty again, this should be the firing order of a Rolls-Royce Merlin engine. I slow down the simulation in the video, so stepping frame-by-frame with the period and comma keys on your keyboard you can see which cylinder is firing next, and for reference the cylinders are numbered 1 through 6 on the right side, starting with 1 at the bottom of the firing order graphic in the top-right, while the left are likewise numbered 7 through 12.

.connect_wire(wires.wire1, (0.0 / 12.0) * cycle)
.connect_wire(wires.wire2, (8.0 / 12.0) * cycle)
.connect_wire(wires.wire3, (4.0 / 12.0) * cycle)
.connect_wire(wires.wire4, (10.0 / 12.0) * cycle)
.connect_wire(wires.wire5, (2.0 / 12.0) * cycle)
.connect_wire(wires.wire6, (6.0 / 12.0) * cycle)
.connect_wire(wires.wire7, (7.0 / 12.0) * cycle)
.connect_wire(wires.wire8, (3.0 / 12.0) * cycle)
.connect_wire(wires.wire9, (11.0 / 12.0) * cycle)
.connect_wire(wires.wire10, (5.0 / 12.0) * cycle)
.connect_wire(wires.wire11, (9.0 / 12.0) * cycle)
.connect_wire(wires.wire12, (1.0 / 12.0) * cycle);
So the first from the bottom on the right aka 1R, then 6L, 5R, 2L, 3R, 4L, 6R, 1L, 2R, 5L, 4R and last 3L.
