What if they made a 2 stroke rotary? Both are known for high HP compared to displacement.

>>14772594
rotary engines are more like allstrokes since there is always an intake, compression and exhaust going on. in any case, premixing oil into your gas is a constant I guess

>>14772605
So a two stroke rotary would have 2 intakes, compressions, and exhausts going on.

>>14772799
so a 2 rotor?
otherwise you'd have to add 3 more sides to the rotor. a hexagon rotor would be far too much trouble, way more sealing problems, less movement capability, smaller area for combustion, balancing problems since explosions would have to be timed in a weird way and wouldn't add much power

A 6.0L turbo will make more power than a 2.0L turbo, all else being equal.

>>14772937
A 3.0L turbo can make the same power as a N/A 5.0L, yes. But why would you want to do that when you can have a 5.0L turbo that makes much more power than both? Plus it won't be anemic while off-boost and have a better power curve as well as faster spooling. And best of all it'll be more reliable.

>>14772970
It's real too:

holy fuck

>>14772983
well there's always a stroke, sorta. strictly speaking, there isn't a stroke at all in a rotary. it is always doing all 3 processes of combustion constantly

>>14772986
Because in that scenario I would not be replacing displacement.

>>14772986
a 5l turbo won't be more reliable than a 3l turbo, are you retarded? and a 5l turbo is probably more expensive to run. not only in gas, but also in maintenance. it's going to make more power, so more wear on everything.

>>14771735
nice

>>14772996
>it's going to make more power
Exactly. More, displacement, more power. Can't replace it.

>>14771888
Wouldn't that overheat?

>>14773003
well but a 10L NA will make more power. but a 10L turbo will make more power. but a 15l na will make more power.... etc it's a circular argument

>>14772990
Two cut to the chase one dorito=3 pistons but the pistons are not at the same stage in the 4stroke process.

>>14773010
Exactly, if you have a 3.0L engine and 5.0L engine, the 5.0L engine is going to be more powerful. So in order to replace the missing 2.0L of displacement between the two, we can add boost and the output of the two engines will be much closer to equal.

Therefore, we can replace displacement.

You mean chassis codes that everyone around the world fucking uses?

Forced induction, 2 strokes, rotaries..

However you can never beat the torque delivered from a larger displacement engine.

And unless its a motorbike, or you are tracking at high rpm, torque will always be better. More reliable, more useful, more predictable.

Torque < Horsepower

>>14771689
Replacements for displacement:

>Increased RPM
>Increased compression
>Variable valve timing
>More valves per cylinder
>Electric/hybrid assist
>Turbocharging
>Supercharging

Technically speaking, using a 1.3 rotary and comparing it to a 1. 4-stroke piston engine IS increasing your displacement, or at least your sewpt volume.

>>14775473
Those are alternators. That truck was for a car audio competition, had something like 32 50kW amps in it.

You're confusing nitrous oxide and nitromethane there.

>>14772873
>will a 6.0L Turbo make as much power as a 2.0L QUAD TURBO?
No, because 4 turbo's =/= 4 times the boost pressure, and it´s the boost pressure (assuming identical intake air temp) that adds power.

>>14772881
Because that'd be a bitch to pipe. You'd have two sets of two cilinders, and then two individual pipes, running into four turbo's with 2 different a/r's/diameters etc.

>>14772996
Actually, no, it'd be less tressed, and therefore wear would be less. Sure, part-throttel gas consumption would be higher with the added ring drag, but still, power potential will be higher, and the engine wear would be lower for an identical power goal.

>>14773019
We cannot practically replace displacement because there is no comparable way that adds unstressed power to an engine.

>>14773006
Between the cooling of the 4 carbs, the big fat radiator, the small superchargers, the underdrive ratio on the pulleys, the lack of an engine bay around it, the lack of stress on the engines - no, it probably won't overheat.

>>14775592
two turbo engines, with the only difference being displacement will be stressed equally. now if you lower boost on the 5l to match or slightly beat the 3l, that's a whole other thing

>>14775655
Two turbo engines, one 5L, one 3L, with identical power output, the bigger oen will be less stressed.

>>14775685
with identical power output, but at that point you might as well go with the 3l since it'll be cheaper to build, and be more fuel efficient when not on boost. Why would you have a bigger engine that makes the same amount of power? The whole point of a bigger engine is more power.

>>14771689
there is no replacement for displacement

>>14775698
With otherwise identical turbo engines, one 5L, one L, and given the same amount of stress, the 5L will massively outperform the 3L.

3L isn't cheaper to build per se. The manufacturer might charge more to the end consumer though. Keep in mind a 3L turbo is usually more expensive to build than a 5L n/a motor.

More fuel efficienct when not on boost can be up for debate. Modern pushrod V8's can easily shut down lifters for example, effectively turning them into small V4's. Can't easily do that on a twinturbo DOHC I6, for example.

>Why would you have a bigger engine that makes the same amount of power? The whole point of a bigger engine is more power.
To reduce the amount of stress on the engine, and reduce NVH - power isn't always the goal. Also, bigger engines can offer identical hp with more torque (in general, depends on bore;stroke ratio and cam selection), so they can have a better powerband down low.

We're getting to the point though, that a well-designed boosted 5 liter engine is making impractical bucket loads of power. We actually have the luxury nowadays to pick between n/a or power adders, because you can make power any way you damn well please - and make so much of it it'll easily overpower the set of tires you chose.
