New Engine Mod: Caterpillar 3412 Diesel 1250HP

[sabretooth]

Hello, I'm a new in modding at American Trucks. I was cruising and I found some inconsistency (imho) with engines, so I've decided to create my own engine.
--
Caterpillar 3412 Diesel 1250HP v12, but with small Chip Tuning. So the default max rpm is about 2200, and according to calculation the power is 932,125 kw.
The idea is to increase the rpm (normally how chip tuning is done) from 2200 to 2800, and changing the engine volume from 15.9 to 19.8 ~ roughly 20, so called swapping crankshaft and piston diameter.

Initial Calculation:

Old Value: HP 1250 v12, 15.9, 932.125 kw, x 2200 rpm, 4045.76 n.m. torque
New Value: HP 1600 v12, 20.0, 1096 kw, x 2800 rpm, 4068.88 n.m. torque

Modding:

I decided to apply those changes into the game, according to engine specs and https://modding.scssoft.com/wiki/Docume ... ngine_data, this what I have done:

Code: Select all

torque: 4068.88
volume: 20.0

torque_curve[]: (250, 0)
torque_curve[]: (500, 0.5)
torque_curve[]: (750, 0.8)

torque_curve[]: (1000, 1)
torque_curve[]: (1500, 1)
torque_curve[]: (2000, 1)

torque_curve[]: (2400, 0.8)
torque_curve[]: (2600, 0.6)
torque_curve[]: (2800, 0.4)

rpm_idle: 500
rpm_limit: 2600
rpm_limit_neutral: 2400

rpm_range_low_gear: (750, 2400)
rpm_range_high_gear: (1600, 2600) 

consumption_coef: 1.2
adblue_consumption: 0.88
no_adblue_power_limit: 1.0

So when I've applied this changes, I really start to feel, the chipped truck, however can someone help me with setting up an 22 or 24 positional transmission, and braking, because with this specs, the truck is braking very heavily

A 3412?? dang that's a extreme rarity any videos of it in-game?

Well yes, this is an old engine, but I watched in YouTube a while ago, how random guy were testing and fixing that engine in Kenworth truck, that engine is huge
