What's done in that video is not a good fix and in fact it introduces new failure points. This has been discussed in another thread
here and I totally agree with

I have seen a similar fix done with two holes drilled in the timing sprocket and the timing sprocket cracked from the drill hole.

I'm not even planning to do anything beyond 500whp but for the peace of mind I just bought the full VTT spline lock kit, which doesn't require drilling and everything can be done for $1800-$2000 including parts&labor depending on the shop. If I wasn't planning to tune, I would just leave it alone and let the warranty handle it (if and when it happens).
