Engine bay tank...
Who is running a engine bay tank here ? Since I installed mine nothing but high IAT , I am only running single pump I think to relocate it in the trunk and add extra pump , I don't think a single pump can keep up my IAT whee high as 195 deg passing the 1/2 mark at the last wanna go fast event.

Pump is brand new and is working not sure what's going on I belive the way the tank sits in the engine bay one pump might not just be enough for some reason it keeps cathing air. I did bleed the system. 3 times so far. I think adding a extra pump would be the goal. Wanna go fast is 1/2 mile event from a dig.

Are you saying after you bleed the air out, "later"you are finding more air?
Tell us what procedure you use to bleed the intercooler.
Two pumps is the goal? then pick a good one here VVVVVVVVVV

Engine bay tank looks good but is it functional?
For what it is worth, I am not a guru, but more of a forum stalker for pre-mod advice and analytics
I read a thread that stated that the feed for the engine bay tank was a bad design, when at WOT the acceleration starved the feed circuit and basically ran it dry due to the feed being on the front side (radiator not firewall) of the tank... logically it made sense. But like I said what do I know
I think the tank mentioned was an FTP tank.
195 sounds crazy high fwiw too talk about no boost if still clutched

how long have you had the set up? Some guys have had FTP build it with the return line in the back OR had an inlet return built into the tank that runs horizontally tied a back corner.
also, buy a vrp superflo pump ($250) and have it set up to run whenever they key is in ignition.
so, have the FIC done asap and while you are at it add water/meth Injection. JMB614 and Hulk have state of the art set up and I copied SeanO with a fairly inexpensive snow kit.
IAT on a 58 degree started at 48 (I have a killer chiller) and ended at 63 on a 40-130 pull.

I use a ftp tank I datalog and monitored my IAT and at full throttle pull at 3rd gear my IAT went from 99f to 199f, that made me crazy
I know fixed 77m pulley its make it worst, so the next day I drain the water and try it with IC cubes and datalog IAT was 
from 99f went all the way back to 65f with 3rd gear pull went to 119f
. but it wasn't enough by using ic cubes it wont stay for more than 2 hard pulls and the 3rd pull my IAT jumped to 155f.my next plan is
new IAT sensor
dyno, 1- pull with water
2- pull using dry ice
it may be stupid Q to ask what is the difference between feed being on the front side or back side at the end the suction water will be by pump. feed me with any best options I really want this bay tank to work better.

spot on. I had my return line moved to the back of the tank and front return line capped.

also, buy a vrp superflo pump ($250) and have it set up to run whenever they key is in ignition.

When you punch it, all your water is pressed against the back wall of the tank. Find a way to draw it in with your pump. I would get a large pickup tube welded in that reaches to the back. Then send the bill to ftp.

stock pulley that was stock heat exchanger at the time split 03 cobra tank 46deg rise in the quartermile so at the end it was 109deg. On the dyno 27deg rise ended at 90deg. I was in the 150deg act range with ftp tank and aftermarket heat exchanger before the end of the quartermile.

I too run the cobra tank and keep contemplating adding a large (5 gallon) tank in the trunk and a killer chiller....The FTP tank had some issues that I highlighted a long long time ago.
