Which is a better drive ratio
end gear lower or higher? i want the highest possible top speed from all the non modded transmissions and so far 124 is the most I can muster with the 10k hp engine

A higher final frive is better for speed, but this will compromise some pulling power

good to know

It's the same principle as gears on a bicycle or a race car. You use lower gears to get yourself going and higher gears to maintain or build speed. Depending on your weight, in top gear you can build speed from your momentum if you apply enough power, or you can lose speed and stall if you don't apply enough power.

A splitter works the same way, you'll use the LO to pull and the HI to cruise, basically, although you also can use them to transition to the next gear. Trucks use so many gears since they are a lot heavier than a car or a bike. Bikes use a lot of gears since human muscles aren't all that powerful, even if you are an Olympic athlete.

the modded 10k hp engine is capable of more speed ant it lifts everythign with ease but I want to know which transmission in the game that is not modded gives the highest speed overall

http://i.imgur.com/GbGvWG5.png this is what I mean, I am using the Eaton Fuller* 18 gear transmission with the built in retarder, is this the transmission which has the highest speed?

No, actually, it doesn't - and you won't. The splitter is for intermediate gearing (ie. for transitions).
You'll use the splitter only if/when necessary to make the upshifts workable within your engine's peak torque range. If you don't need to split gears, you just won't.

You're conflating the gearbox's splitter with the range gearsets. Low-*range* gearset for moving off, high-range gearset for cruise (roughly speaking).

OP:

Generally speaking you're looking for the gearbox with the *lowest* final drive ratio. However it might not quite be that simple depending on how low the gearbox's output ratio happens to be. In general though, the lower the number for the 'final drive' value the faster you'll cruise at a given engine RPM.

Still isn't an answer to my main question though, which transmission in the game is capable of the highest speed? http://i.imgur.com/GbGvWG5.png this is what I mean, I am using the Eaton Fuller* 18 gear transmission with the built in retarder and a maximum speed of 124 on its 18th gear. Does this transmission have the highest speed possible or do I have to get a modded transmission to get the highest possible speed in game if the other transmissions can't reach 124 or higher?

Dude, if you think I'm going to go and test every available transmission and engine combination to give you a definitive answer, you'll have to come up with another thought :P

We've given you all the information you need to figure this out for yourself. The vanilla 18 speed box has a final drive ratio of 3.25. Do you see lower ratio final drives in the gearbox list?

yes but so far still wasted 200k testing them anyways and nothing gets faster than the one i am currently using

Well, maybe someone else will have a better answer for you from their own experiences. Top cruise isn't something I put any level of priority on when I'm choosing my driveline.

10k hp engine which is a mod makes easy work of everything,since I make enough money from my drivers in game to goof around and just drive i want to go the highest possible speed but I am pushing myself when I got the engine mod already since I do not like mods regardless of how they could help the game

Understood, I'm not criticising the way you want to play your game.
