It's funny how I seem to be making the questions and the answers here

New formula for the IJN torpedoes explosive power :

weight of torpedo warhead IJN / weight of torpedo warhead US
------------------------------------------------------------- * 1,07 (Type 97 ratio vs TNT) * 120 (MK14's game explosive power min)
1 (TNT)

405/292
-------- *1,07 * 120 = 178,089

Well, here's what I understand :

German Hexanite isn't much better than TNT.

in game German T1 and Te and TIII torpedoes have these values :

MinEF=120
MaxEF=180
AP=100
Minradius=3
Maxradius=7

the homing ones have less, taking into account the homing device :

MinEF=80
MaxEF=160
AP=100
Minradius=3
Maxradius=7

the US mk14 has the same values as the T1a !!!!! :

MinEF=120
MaxEF=180
AP=100
Minradius=3
Maxradius=7

So the Mk14 they modded here represents the early war mk14 with a TNT warhead.

Then the Type 97 explosive warhead should have 1.07 times that value as per same warhead weight.
