Many people have tried and *nobody* has ever posted dyno results or videos showing how "well" their pod setup runs at all RPM's under load. Conversely there are many many threads of users with a bike that has pods and doesn't run right.
Way back, a user *did* post dyno runs with both the stock airbox and "properly jetted" stock carbs with pods, showing a rather significant loss in horsepower.
You're welcome to try but it's a bottomless pit if you're researching and you'll spend a bunch on jets. The only way you ditch the stock airbox properly is to buy a different set of carbs -- which come in $650 or $1200 flavors off the shelf from Murray's and Cycle X. I have also read that certain years of Suzuki GSXR carbs fit with minor mods and take to pods a lot better but that will require some research and Ebay finding.
The stock carbs are CV models, highly sensitive to intake vacuum, and the stock airbox provides that evenly across all four when it's working right.
I will say that the Dynojet kit you posted tracks with what I've read. The instructions tell you to drill larger holes in the slides and they also call out a specific set of K&N filters by part number for in-airbox and pods. The slide drilling might make the carbs work better for pods, but it's a permanent mod unless you can sleeve the holes back down to stock.
