We need a "longstroke" 91 to swing a big prop at a little lower rpm similar to the 4 bangers.

I've seen the OS91FX piped to the proper length turning a 15.25X12APC 4blade at 7800-8000. Yes it isside exhaust and requires the wrap-around header and Yes I'd love to see a rear exhaust "hanno" with the built -in pump BUT it wouldn't be for $199 for sure.
