Haha yeah I kinda did the same thing before in an old Fold conversion van. The cruise control got stuck on at 70mph, and I couldn't turn it off by pushing the brakes or the button. I was left with the only choice of throwing it into neutral, at which point I thought my engine was going to explode like you did. I also killed the engine, but that made it very difficult to maneuver the beastly vehicle around the traffic jam that I was quickly approaching
I would think that everything would be fine with your engine, assuming that your rev limiter is functioning properly. Definitely won't be making that mistake again now will you
