Well -perhaps -some day --I will see one -
right now -I have only 24 hrs in each day and all my time for engine stuff is full.
FWIW- we are doing comparison tests on various exhaust setups on rotary valve and reed valve engines - (has nothing to do with piston port stuff tho ) just trying to do what is required at the moment to help a friend.
I will not be putting the results here - So far the info we have would drive some people crazy.
You would probably love these tests.
