Setting a new world speed record! 2500kph

[jcd]

Actually i think (could be wrong) that a spoiler can also reduce drag. I had a class in fluid mechanics this year where i learned that the drag in the same speed turbulent vs laminar air flow is different. Significantly less in turbulent flow.
So a spoiler that increases turbulence may actually help reduce drag at high speeds.
Also, this is why golf and tennis balls are not smooth, to go into turbulent flow more easily.

Digging a bit into it, wikipedia seems to agree.
Quoting: The goal of many spoilers used in passenger vehicles is to reduce drag and increase fuel efficiency.

In truth what happens is quite complex. see here for slightly more insight: http://en.wikipedia.org/wiki/Flow_separation

Ofc, i do agree that many spoilers also create a downwards force to improve traction (also make sure the car will not fly)
I still remember the flying mercedes of the le-mans rally a few (10?) years back: https://www.youtube.com/watch?v=h0t5juiDfr8

Hint: turn the trike into a single “line” - the thinner the vehicle is, the better its aerodynamics. Also, try to find a better wheel setup - you can really gain a lot of speed from optimizing total wheel area.

[quote=“Coolthulhu, post:11, topic:9055”]Cars with more “columns” have worse k_dynamics. “Columns” with an obstacle in them cause worse penalty.
That’s it.[/quote]

Taking these into account, i did a 3rd run.

Vehicle:

as you see, it has the same max speed, but better k_dynamics and slightly less weight than before.

Top speed: 2850kph! (~1770 mph)

I now believe that someone can go over 3000kph if he used only the largest V12’s, using as many as possible until adding more actually reduces top speed.

Next time as soon as engines die and you start losing speed, pull a handbrake and see what happens.

I tried it 3 times, i manage to break without dieing. Hell, consecutive handbrakes made me avoid the collision altogether! I have 7 driving skill though.

WOAH. Congratulations! And more destruction please.

Here comes more destruction then. And its on !fire!

who need hyperdrives while we have v12 engines?

[Kryxx]

daaang… Okay. We now need dragster chutes to slow down vehicles faster.

Wait, the volume of the engine actually matters? I thought wheel radii and engine sizes were just flavor, only the number of cylinders mattered. Am I wrong? 'Cos I’ve mixed 20-inch and 14-inch wheels on alternating sides of a vehicle with no visible effect.

Remember what the “liter” for the volume of displacement for all cylinders for the engine. Removing the spark plugs and the drop the pistons down, and that is how it’s measured. in RL volume isn’t exact, as there’s a lot of other mechanical things you can do for better air burn and displacement, and how many revolutions it’s making etc. Including the airdynamics and other things people here were discussing to make sure the car doesn’t air lift or flip.

But for this Cata DDA, it’s straight math.

V12’s have typically over 1 liter per cylinder of displacement, which is what you want for raw power. Someone in another thread posted one with 15.92 L or something.

dragster chutes for the car should be craft able easy enough. Just some rags, plastic and string or something.

Got to this while using the debug to give me items
1919 MPH is roughly 3088 KPH

Used 12 15.00L V12, and 14 15.75L V12

Feh. Anyone can use the debug menu to make a dragster.

But using the debug menu, as it will itself tell you, is CHEATING!

Anyone can grind for parts. Designing a vehicle is a bit harder.

A bit, because it’s still simple (MOAR ENGINES + approximate a formula for wheels), but it still takes more skill than grabbing all the stuff, which only takes patience.

[Litppunk]

um… no. bull. survival building you have to survive long enough to get all the pieces parts, and if you either don’t know until latter, and/or you just wasted that piece you spent so much time getting. Survival building is much harder because it requires all the challenges of GIVING yourself any parts you need with the additional problems of getting the parts, and being restrained by what you find. MUCH HARDER.

Tedium is only difficulty in the way that you can get bored and quit.
With no risk of death, you can just go through the (infinitely generated) world, collecting parts on your way.

If you know what you’re doing, the only two things that can kill you are tankbots and sinkholes (those traps that spawn in swamps). If you know how to avoid those, you can’t die.

And if you don’t know what you’re doing, you won’t build a fast enough vehicle anyway.

[Litppunk]

Only once your character is good enough. And risk of getting bored and doing something stupid enough to get you killed before quitting is part of the risks. You can’t just discredit that because getting cocky, and getting bored are two of the main threats.

I was just posting that as confirmation that 3k+ KPH was possible. Easily achievable, not so much.

[Funk]

Only 3K? i got mine up to four and a half before the fuel tanks ran out.

Im rebuilding it to use 15 V12 Engines and have an enclosed cockpit to give it some crash safety and deal with the wind chill.

That is a super awesome design. Imma use it once I get to that point in my current character…
wait
15 V12 ENGINES?

Amazing!
This almost makes me want to debug V12’s and find the real max speed we can go.
Otoh it also makes me want to research and add better wind drag and wheel friction for vehicles + needed wheel quantity & quality depending on vehicle weight.

Btw 4500kph means around the world (at the equator) in under 9hrs!

Decided to join you. Also discovered random bug while playing with cars.

Here I go:

[Arek_PL]

we need desert map back for pepole who do things like that

[Litppunk]

salt flats ^.^ Dragsters dream map

[Valiant]

So it logically concludes to necessity of adding some jet drives for cars like these.

[Kryxx]

I still think being able to make drag parachutes. from parachutes (and/or sheets), rope, plastic, a scrap metal + backpack. Cuz you need to pack the chute.

and then you say “but parachutes are not in yet”, Think, multi z levels incoming sometime.

Being able to jump off a roof and land at a random spot below via a parachute would be awesome. Especially if said chute was damaged and you reached terminal velocity jumping off the 20 story hotel.

So you make parachutes, and then allow the application of them to said vehicles to slow them down. Useful for emergencies and fun stuff.

Also opens up more recipes like turning them into tents

I need to get over to the suggestion area.
