Dry flow is nice, but you engine doesn't run on air alone.

Mondello and Reher/Morrison are pioneers in this area.

Great article in my shop suppliment on a hemi that flowed great numbers but wouldn't run, then the wet flowed and flow vortexes in the chambercreating wet spots around the plug. Did some wet flow porting and didn't pick up any more flow but the engine came alive.

You need the sharp edge in the chamber near the plug to break up the mixture and enhance flow. Exhaust side is already burn and ya just need to get it out without turburlance. How much or long of the sharp edge and steep an angle can only be found with a camera, dye and wet flow testing.

Not that I know what I'm talking about, but the best 87 cc E-heads I ran on my car never had any chamber work and ported to only 305/310 on a dry flow bench. But big ports for Nitrous, if that mattered.
