Vital Strike and Perfect Strike interaction?

[Xyllen]

Does the ability of perfect strike to maximize weapon dice damage include vital strike weapon damage.

[Brotato]

Perfect Strike doesn't maximize weapon damage, it lets you roll two d20s for an attack and use either one for your actual roll.

[Xyllen]

the magus one is:
Perfect Strike (Ex): At 4th level, when a kensai hits with his chosen weapon, he can spend 1 point from his arcane pool in order to maximize his weapon damage. Don't roll for damage—the weapon deals maximum damage. This affects only the weapon's base damage dice, not additional damage from sneak attack, magical weapon properties, spellstrike, or critical hits.
If the kensai confirms a critical hit, he can instead spend 2 points from his arcane pool to increase his weapon's critical multiplier by 1. This ability replaces spell recall.

The ability tells you the answer. Vital strike damage is not base damage.

vital strike says roll damage dice twice. Both rolls are base damage dice. That is why I ask. It's two rolls not extra dice.

No, only the regular die for that weapon is base damage, the extra damage from Vital strike is bonus damage.

This is why it's not increased on a critical hit.

Tho it aslo says additional damage, just not addtional damage dice.
"When you use the attack action, you can make one attack at your highest base attack bonus that deals additional damage.
Roll the weapon's damage dice for the attack twice and add the results together before adding bonuses from Strength, weapon abilities (such as flaming), precision based damage, and other damage bonuses. These extra weapon damage dice are not multiplied on a critical hit, but are added to the total."

Vital Strike damage is considered Weapon Damage (especially since it is scaled based upon the weapon you are using), but for the purposes of Perfect Strike from the Kensai, the subject you linked states the weapon's base damage, and that it excludes other sources, such as Sneak Attack Damage and the like; since it only affects base damage, it won't affect Vital Strike damage.
