Of course the car will make roughly the same power with an open cone versus a Thrasher box or other CAI setup – because the tune remained the same during all pulls. While using a CAI, the owner of the car failed to re-tune his car and add more timing to take advantage of the lower IAT… of course he’s not going to make any more power.
I think the big problem with this is the way the M90 efficiency really is. Sure it crams in air...and colder air is better...but it's still going to heat it to umpteen bazillion degrees because that's how it works. So getting 10 degree cooler air through the blower is still going to be umpteen bazillion degrees...just maybe a tad cooler.
