I love what you've done.
I'd recommend you remove your rear grill to really let that thing roar. Try setting your forward top fan to intake to provide more air to your push fan.
It's definitely . . . cool.
EDIT!!!:I have flipped the fan on top that is nearest to the push fan to suck in air and i left the other one as an exhaust so that its also helping exhaust hot air from the pull fan. Since its almost 2AM in NY i wont be able to start it up without waking up the whole family . But i will try to get some numbers ASAP!
