Hello guys! I need a to edit a truck mod, so the engine has 430 HP. If i use the formula (HP*0.0044=torqueScale)>> 430*0.044=1.892. But this is for default torque curve and a maxRpm of 2200.
This is what i have now:
<motor torqueScale="2.889" minRpm="750" maxRpm="2500" maxBackwardSpeed="15" brakeForce="10" lowBrakeForceScale="0.21" lowBrakeForceSpeedLimit="1" minForwardGearRatio="13.5" maxForwardGearRatio="100" minBackwardGearRatio="50" maxBackwardGearRatio="130">
<torque normRpm="0.45" torque="0.8"/>
<torque normRpm="0.5" torque="0.9"/>
<torque normRpm="0.59" torque="0.95"/>
<torque normRpm="0.72" torque="1.0"/>
<torque normRpm="0.86" torque="0.95"/>
<torque normRpm="1" torque="0.85"/>
</motor>
is this good for 430HP or should i put motor torqueScale =1.892? thanks.

I'm no good at math so I do it the easy way. I just find a mod that has the 430 HP and copy it's xml motor part and paste it over the xml of the mod I want to change. That way I don't have to strain by brain with that math stuff.

I agree with @farmboy002, try and find a tractor with 430 HP and just copy and paste that stuff and it should work.

in fact there is an excel file in the sdk to type in the HP you want and it will calculate the values you need to put into the motor-section
its mainly the torqueScale and the maxRPM that are needed to calculate the HP ...
i hope you find the file i mean, if you don't i could upload it for you (got it somewhere in my archive deep down in my FS15-catacombs)

Thanks for replys guys. @Aranea if u can dig up that excel file it would be great. I did a google search for FS15 SDK and couldnt find anything.

you got it on your pc where you installed FS 15 in the folder called "sdk" the file is named vehicleMotorCalculator.xls

thanks! i found the xls. this will help me alot!

I have used many mods but non can compete the original vehicles, like i have downloaded a man truck with 680 hp,
Torque Scale = 2.992
Max RPM= 3000
but it can not pull two trailers full of wheat, it stops on climbs and heavy landscapes while the genuine Tatra Pheonix with 462 horse power pulls it smoothly, though Man 18.680 (Mod) is fast but weak, whats the matter here?

It's probably got more power than grip, try increasing the wheel mass and/or friction scale.
The lines for wheels/suspension are normally close to the top of the vehicle.xml file, from memory they start with autorotatebackspeed, and there is a line for each wheel. Try changing the mass value to 3 on each line, and the frictionscale to 3 also, this should massively increase the grip. If there is no entry for frictionscale, you can add it between two of the other values, following the existing formatting.

"I have tried it and it does increase the grip. Now the man 680 can pull three trailers full of wheat, about 180000 liters. Thanks "
