Engine files are finished, but I would need someone else to model the engine and create sounds. I can upload the engine/kart now if you like?

Sam

Different power curve and gear ratios (2 gears), changed weight

how much ratio the secodn gear should be? there is a strange " ratio1 = 25, 21.5"


jamiecraig20

The ratio is strange, as the DD2 has no real input and output gears, the gear simply slides on a shaft. So I played with the ratios till they were about right

here you can find numbers of teeth for primary and secondary drive gear for first and second gear http://www.rotax-kart.com/upload/files/88.pdf you can find also many others informations such as min and max temp of engine, max rpm ecc


jamiecraig20

These gear ratios do not work, as the primary and secondary gears stated in that are the primary gear and idle gear, so the ratios would be wrong

sorry i haven't understood, what is the idle gear?

i read first gear 4.26 so 15/64, second gear 3.21 so 14/45

so it should be

FSprocket
   {
      gear0 = 32
      gear1 = 33
      gear2 = 34
      gear3 = 35
      gear4 = 36
      gear5 = 37
      gear6 = 38
   }
   FSprocketSetting = 3

   RSprocket
   {
      gear0 = 59
      gear1 = 60
      gear2 = 61
      gear3 = 62
      gear4 = 63
      gear5 = 64
      gear6 = 65
   }
   RSprocketSetting = 3   
}

gearbox
{
   NumGears = 2

   ratio0 = 15, 64
   ratio1 = 14, 45

        Gear0 = 0
   Gear1 = 1

am i wrong?

jamiecraig20

If you set the gear ratios like that, the top speed is 32km/h

Capeta

what is strange is that i can have 275 km/h easylly but in real i can't ahve more than 140.
any tips for to have a speed kart?
I have succeded to have a kart very nervous even in 6xt gear we can make 360 in 5 lol. it's fun and hard but not my goal :)

jamiecraig20

If it is nervous, add more ballast weight, also to make it faster try changing the first and second axis' inertia and friction. Also change the efficiency. Add more torque in the .engn file.
