I have an aircooled hood in my tent but i dont even have ducting plugged into it right now. I just have my inline blowing air outside from the top of the tent, and a CF attatched to the side of the inline that is sucking air. perfect temps
All I can say @ this point. is why don't you just move the fan to the other end of your setup. Just for shits and giggles... Never know till you try.
500 CFM fan should be able to pull the air through your system.
Any bend in ducting is efficiency lost from your fan.
15% lost for every 90degree bend.
15% lost for every 10ft of ducting.
20% lost from adding a carbon filter.
Which of these three is the only one you can't live without?
Right your carbon filter!
Remove any 90degree bends and try to replace with nothing smaller than 120degrees. With a 120bend you only loose around 5% efficienc.
Your 500cfm fan with attached filter and 2 90bends reduces down to around 250-300cfm.

I say there will be a big difference.
Move your fan, trust me. Read everyones post. There saying "Pull" and not "Push". Fuck i had a 6'' before it blew a barring and i had to buy a inline fan dial to turn it all the way down. I have a 1000w hps w/ digital ballast.
Another question though, even if I am only getting 250cfm, shouldn't that still keep my room cooler than what I am seeing. Seems like the CFM would have to be even lower to get the temps I am seeing. I am going to follow all your advice and the first thing I am going to try is to move the inline to the end of the chain and see what that does. Now I am wishing I wouldn't have used so much foil tape lol. Going to be a real pain to move the fan. I'll post an update after I make the change.
Ive seen 2 - 600ws ran in a 4x4 with 1 6'' fan going full force.
