BTW: nice job & I appreciate the work & the gas you ate doing this little experiment.
Thanks, bud! A/C off, top down!
I dropped the underhood intakes/cone filters like a ...hot rock!
I am now back to the stock airbox with K&N's. I'll next remove the little restrictor plates that feed through the radiator bulkhead and find a flexible coupler that actually works and can keep a minimum 2.75" diameter through.
I carefully measured the area of that little oval tube feeding through the bulkhead and found it to be only 3.975 square inches each while the intake tubes on the airbox are 4.713 square inches each (15%). They gotta' go!
Other folks have done this and now I see why.
