Flame travel speed is also a problem especially with large bores at high rpm's(combustion chamber shape plays into this). But spark ignited engines have an upper limit usually stated at 6". No consumer car engine is even close, but it is good to note that there is a limit.

I also have several books that state that frictional losses associated with side load changes is negligible. Larger bores also have have more surface area for frictional loss. These are all part of the qualifications statement from the previous reply.

Off to the jet airliner
Have a good weekend.
