although im sure they can work on mild hp motors , i would never lock it up and expect good. after i tried telling yank what happened and sending a file of my tune for them to inspect i still had to pay for them to rebuild my yank to salvage what i had invested. in short they told me i was doing wot lock ups and it caused it to fail , i didnt and i know it . swap to a convterter they dare you to break under any circumstance, that is what i needed.

my 2 dollars.

DrX has also had this issue of a yank clutch failing under normal usage. From what I hear, it sounds like that issue has been fixed with their multi-disc, though.
