That's a fortunate turn of events that brought it to a good home, rather that suffer the fate of a part out from loosing interest.
Good on you!

An air/air is only going to pull so much heat out of the system. If you took your i/c and make it a single pass the air would move 1/2 as fast through it so it would cool the same with 1/2 the pressure loss. On top of that it has to make a 180 degree turn to go the other way. So now you've slowed down the air, and dropped the pressure loss. And lets use a 13psi pressure loss and a 18psi intake pressure. So your turbo has to spin to make 31psi. This means the compressor is pumping more heat into the air which taxes the i/c more. On the exhaust side you've noticed how going to a bigger turbo has helped the car breathe. Now imagine if instead of opening the WG at 31psi you could open it at 18!!! And how much farther it would open to keep the boost lower. Lower compressor speeds means cooler air so the i/c doesn't work as hard which will lower your intake temps. Lower turbine speeds means more flow sooner. which all equals more hp. A slightly larger single pass unit with a 1-2psi pressure drop or less and you could probably hit 11's@18-20psi with good traction. Our points is that you're leaving a HUGE amount of hp on the table with that i/c. T3's like lots of flow and you saw this with the turbo upgrade. Now you need to upgrade your intake side. You've upgraded everything else for flow then stuck a cork in the system.
Ok, I have thought about cutting the end tanks off and making a single pass out of it. I'll weld a fitting in the intercooler tube pre cooler and get some readings to see how much pressure loss I'm actually dealing with, if it's to much I'll modify my cooler or buy a better one, thanks for the advice!
