I dont disagree with your findings, obviously you have the dyno sheet to prove them. I do however disagree with your methods.
Almost all intakes will show gains over stock on the dyno due to the "restrictive" nature of the stock airbox. However, at speed, the stock airbox does create a "ram air" effect from its snorkel that is virtually impossible to replicate on the dyno, making the real world difference between intakes much smaller.
The real test would be to go to the drag strip and datalog an entire pass with each intake, and compare the average MAF flow of each intake (specifically at peak whp rpm). A rough rule of thumb is ~1 lb/min = 10 crank horsepower. Assuming a ~15% drivetrain loss for RWD applications, that would be about 8.5 hp at the wheels.
For your claims to be true, i would expect to see an increase of .85 to 1 lb/min of MAF flow in those logs to simulate an actual increase of ~8.5 to 10 whp. I look forward to your results.
