Velocity of 200 is already very close to speed of light

You can also try this:

pawn Код:

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
    if(GetPlayerState(playerid) == PLAYER_STATE_DRIVER)
    {
        if(newkeys & KEY_FIRE)
        {
            new vehicleid = GetPlayerVehicleID(playerid);
            new Float:angle;
            GetVehicleZAngle(vehicleid, angle);

            new Float:velox, Float:veloy, Float:veloz;
            GetVehicleVelocity(vehicleid, velox, veloy, veloz);

            velox += floatsin(-angle, degrees);
            veloy += floatcos(-angle, degrees);
            SetVehicleVelocity(vehicleid, velox, veloy, veloz);
        }
    }
    return 1;
}
