For the 100bhp you are talking about, I think you will have no problem at all on even a modest spec YB as they are so strong from the factory, but it depends how far you are pushin things in the first place with what turbo you are on etc?

My T34 car with 100-125bhp jets was EPIC frankly, went better than a T4 car but spooled quicker than a T28 one as the nitrous spools the turbo so well.

Only downside is the cost of the gas if you use it a lot.

As Rod says the mixtures that you will get advised on by WON are generally a touch conservative, but that said they will still work VERY well and will be on the safe side which is no bad thing.
