ok so the question was asked.

"what is the Highest Redline of any production piston engine?"

after 2 or 3 people started a fighting over some Domestic car i looked for the answer.

turns out honda holds the record

Highest Redline
Internal Combustion Production Car: Honda Integra Type R 11,000 rpm

there was several other interesting firsts for honda/acura in the list thought i would post this and add a link to the wiki
