I use an Neil pryde glide powerbox foil on my JP FSW 94 ltr (2022), this board has a foil appoved powerbox
It work well with a fin and the Neil pryde glide powerbox foil , but this board is or me (73 KG) a little small volume to uphoal

I also have a severne dyno 105 2020, has anyone used this board with the Neil pryde glide powerbox foil ?
I think I have to drill the powerbox hole in the board litte bigger for the NP M8 bolt...

greetings from Bart from the netherlands

I wouldn't do it, I doubt the dyno box can take it. At least ask severne first.

Short answer is no. It won't last.The powerboxes that are "foil approved" have more reinforcements to take the load of the foil. I have seen people use the Chinook power plate which allows you to use a track mount foil. But I have heard varying reports about how long the boards last before they break.
Seatex repair shop in Torbole, Italy has a picture of a Severne Dyno that has been retro fit with a track on their web site. I guess you'd need some sort of cover to use the board with fins. www.seatexboards.com/featured_item/severne-dyno-foil-ready/

There is nowhere near enough reinforcement in it

I used these from K4 to cover the track mount slots on my board which has both since I use the deep tuttle box instead:
