Nicely done! Luck was on your side because that flywheel could of caused some serious damage to you or someone else. Make sure you don't keep it at those high speeds for long bursts. Don't know the history of your engine but unless it's built properly just don't take it to those speeds.
What I do before dividing into something new is research and lots of it. Always look at different people's methods of doing things and read the comments on the "how to" videos. Usually if somthing is being done wrong multiple people will comment on it. Stay safe
