You are probably way past what 80% of the guys would go. It was an interesting experiment that I thank you for taking the time to partake in. Probably the only thing that would interest me right now would be what would a nice gasket matched single plane intake do for this. Would it slow down the airspeed enough to let the numbers on your last flow test continue to climb instead of stall and drop. Would it calm it enough to keep pulling up to .580 lift. Thanks again for your effort
