Switched from a MP FMIC with AC deleted to a traditional FMIC with full width Griffin radiator, full width condenser and OEM style fan....all for a 97 Thunderbird. To make room for the new IC tube routing, the battery was relocated to the trunk. While the car was apart, the stock timing chain was also upgraded to a double roller billet set from SCU. Good thing because Dave found that my chain tensioner was broken and cam sprocket was badly worn. All the old braided stainless rubber fuel lines that were leaking gas fumes in my garage, were replaced with new PTFE braided stainless lines.
After getting the car on the dyno (aka Dream Crusher) we found that air charge temps are much lower (120 F max) and boost is down significantly. Even with my smaller blower pulley (3.375") the most boost it will make now is 19.5 PSI. With the old MP setup it used to make 22 PSI on the large pulley (3.500"), and about 23.5 with the smaller pulley so it's down about 2.5 psi and 30 rwhp on pump gas tune and 4 psi on race tune. Since there are no boost leaks and only about a 2 psi pressure drop on the new inter-cooler, we are assuming the drop in boost is because because of greater inter cooler efficiency but not really sure. It still pulled 450 rwhp on pump gas tune with no corrections for the 80 degree weather and previous stumbles and misfires are gone.
Car is much more pleasant to drive with cold AC blowing and car not overheating. Planning to overdrive the blower another 6.3 % on pump gas tune and 10% on race tune to get the boost and power back up to normal levels. Here is a video and a few pictures of new stuff. Big THANKS to David Dalke at SCU inc for a job well done.
