Im having a hard time formulating this question. Am i doing this math right or can I even apply Power Attack to Iaijutsu?
Level 8 Samurai. BAB +8/+3. 15 Str.
2h Katana is a 1d8+2
Iaijutsu Strike +4d6
Power Attack +6
Min Damage 13+(50%)=19
Max Danage 40+(50%)=60
And does Crit multiply the final damage 2 in total? 38~120?
Power Attack
Benefit: You can choose to take a –1 penalty on all melee attack rolls and combat maneuver checks to gain a +2 bonus on all melee damage rolls. This bonus to damage is increased by half (+50%) if you are making an attack with a two-handed weapon, a one handed weapon using two hands, or a primary natural weapon that adds 1-1/2 times your Strength modifier on damage rolls. This bonus to damage is halved (–50%) if you are making an attack with an off-hand weapon or secondary natural weapon.
When your base attack bonus reaches +4, and every 4 points thereafter, the penalty increases by –1 and the bonus to damage increases by +2.
You must choose to use this feat before making an attack roll, and its effects last until your next turn. The bonus damage does not apply to touch attacks or effects that do not deal hit point damage.
Iaijutsu Strike (Ex)
A sword saint can perform a lightning quick iaijutsu strike against the target of his challenge to inflict devastating wounds while drawing his sword. After the sword saint has challenged a foe but before he has attacked the target of his challenge, he may choose to use his iaijutsu strike as a full-round action, making an attack roll with his weapon as normal. In order to use this ability, the sword saint’s weapon must be sheathed at the start of his turn. If he successfully hits his opponent with an iaijutsu strike, his attack deals an additional +1d6 points of damage. This bonus damage increases by an additional +1d6 at 3rd level and every two levels thereafter to a maximum of +10d6 damage at 19th level. Any extra damage as a result of a successful iaijutsu strike is not multiplied by a critical hit.
After making an iaijutsu strike, a sword saint takes a –4 penalty to his AC until his next turn, but his weapon is now drawn and he may continually to fight normally. Regardless of whether he hits his opponent with the iaijutsu strike, a sword saint cannot use this ability on the same foe more than once per day.
At 10th level, a sword saint learns to focus faster and is able to make an iaijutsu strike as a standard action, and the penalty to his AC is reduced to –2. This ability replaces a samurai’s mount.

Okay, so the text in Power Attack that says +50% also says "This bonus to damage". It's only talking about the power attack damage.
You'll be attacking at +8 (BAB) +2 (Str) -3 (power attack penalty) for a total of +7.
For damage it'll be 1d8 +3 (Str x 1.5 for a two-handed weapon) +4d6 (iaijutsu strike) +9 (6 x 1.5 for two-handed power attack). On a crit it'll be 2d8 +6 +4d6 +18. Bonus dice are never multiplied. Flat modifiers always are, unless they say otherwise.
Except you have to have challenged them first to iaijutsu strike, so that's +8 damage on the regular hit and +16 damage on the critical hit.

Two-handing a katana with a 15 Str is 1d8+3, due to getting one and a half times your Str bonus of +2.
Power Attack with a +8 BAB is -3 to hit for +6 damage, also increased by one and a half times to be +9 damage.
So you are looking at 1d8+12 plus 4d6.
On crits you roll the damage twice, so you end up doing 2d8+24 plus 4d6. (Note that bonus dice are never multiplied.)

Yes, you can apply power attack to iajutsu strike. It is a melee attack roll with a melee damage roll. However, you are doing something very odd with your calculations. You are adding the +50% from two handing in the wrong spot. This is how you would figure out an 8th level samurai with 15 STR and power attack, wielding a katana in two hands:
Katana is 1d8
Bonus from strength is +3 (1.5x strength from two-handing)
Power attack is +9 (6 + 50% if you are two-handing)
Iaijutsu strike is +4d6
= 1d8 + 12 + 4d6 damage
Average damage = (4.5+12+3.5*4) = 30.5 average damage
Minimum damage = (1+12+1*4) = 14 damage
Maximum damage = (8+12+6*4) = 44 damage
Iajutsu strike explicitly states it is not multiplied on a critical hit. Thus, your critical hit damage will be:
2d8+24+4d6
= 47 average damage, 30 minimum damage, 56 maximum damage.

You can not use Iaijutsu strike while using both hands. In the header at the top of the archetype, before any abilities are listed, the second sentence is "The following benefits apply only when a sword saint is using a sword and carrying nothing in his other hand."
If you somehow get a third hand, you might be ok.

Got it i forgot the bonuses from being challenged by a foe.
The +8 i get for my level.
To cover Crit real quick. Its a nat 20 to get Critical Threat. With my Katana its 18-20 for double damage.
After the crit i have to roll past the appoinates AC to confirm the Crit. Example AC 17.
My Attack Bonus of +8 (BAB) +2 (Str) -3 (power attack penalty) +4 (Brutal Slash) +3 (Challenge) a total of 14. If i did that correct.
Do you think that Attack bonus is enough to confirm a crit?
Brutal Slash (Ex)
At 3rd level, a sword saint’s iaijutsu strike becomes even more deadly. If a sword saint threatens a critical hit with his iaijutsu strike, he adds a bonus equal to 1/2 his class level to the attack roll to confirm a critical hit.
Challenge: Whenever a ronin is the target of a challenge, a smite, a quarry, or similar effect, and he issues a challenge against that character in return, the ronin receives a +1 morale bonus on attack rolls made against the target of his challenge and a +1 dodge bonus to his AC against attacks made by the target of his challenge. These bonuses increase by +1 for every four class levels the samurai possesses (to a maximum of +6 at 20th level).

So essentially when drawing my weapon i would apply everything but the (1.5x strength from two-handing) and (6 + 50% if you are two-handing).
But once my weapon is drawn i can apply those to normal 2h attacks.

I just noticed that. If i cant crit with Iajutsu strike. Then why bother having brutal slash as a archetype ability?

This ability replaces mounted archer*.

I think you may be slightly mixed up about criticals too. A katana has 18-20 x2 crit, that means that you threaten a crit on 18-20*, and then just have to beat their AC to confirm (this is what the brutal slash bonus applies to). It seemed like you were adding an extra step there where you needed a natural 20 even on a weapon with a wider critical range.
* Unless it's a miss; a natural 20 is an automatic hit, but even if you threaten critical on them, 19 and lower can still miss. So with your attack bonus of +14, against an opponent with AC 33, you threaten a critical on a natural 20 (an automatic hit), threaten a critical on a natural 19 (14+19=33, so you still hit), but do not threaten a critical on a natural 18, because with an attack roll of 32, you miss. Against an opponent with an AC of 32 or lower, you would threaten a critical on an 18, 19, or 20. Against an opponent with an AC of 34 or higher, you would only hit (and automatically threaten) on a natural 20. You still would need to confirm though, which Brutal Slash makes much easier.

Got it that was never explained to me because campaigns ive been in never lasted that long to run into AC 32 Mobs.
So although my threat range is 18-19-20 it doesn't help if the mobs AC is too high.

Yup. I have a barbarian / samurai who does exactly that:
Round 1, buff and close. Tank the hit.Round 2, challenge, rage, Iaijutsu strike.
Round 3, 2-handed Furious Finish ends rage.
He's only manage to pull that cycle off twice I think, due to enemy and party composition, but it's the plan.

I know it would look silly but why couldnt you draw my weapon with 2 hands. I know it would look silly. But what is stopping me from drawing my weapon with 2 hands. As long as my off hand is free majority of the time?

It says so in the description of the archetype, and also it's how it works in real life - When you're performing Iaijutsu, you have your off-hand on the scabbard. I don't think there's any kind of sheathed sword that's easy to draw two-handed, but I think a properly-worn Katana is even harder to than most.

Ah yes that makes sense after i sent that message i just went through the physical movements and yea i can see how hard it would be.
