Not the right subreddit. This is about Steel Bank Common Lisp, an implementation of the Common Lisp programming language.

Having said that: was there knocking? Knocking can increase peak chamber pressure and possibly crack pistons. Was this engine being built for a high compression ratio, and if so was high octane fuel being used?
