From the motorcycling days we deduced that it works better on fuel injection and if you must use carb then the carb has to be inside a pressurised chamber so that the pressure is equal inside and outside as in supercharged applications. Anyway it's not my motor and invariably it's going to end up in the trash. When I use to run a motorcycle company our new dyno was suppused the have a pressure air feed for tuning ram air but alas I left the company before I was able to get familiar with it.
