I have a 93' LX running twin turbos. On a 10.2 @ 142mph pass, my IAT rises from about 100 to 215-220. 90 degree ambient day, 7000' DA, if that matters. This is with a CX Racing 24x10x3.5 core intercooler. I know they aren't the best, but I expected it to work a little better than this. What I'm wondering is if its an airflow issue or just a poor intercooler. I'm thinking of trying a GT front bumper as it looks like it might flow better. Anyone have any experience with running an LX vs GT bumper? Or will it not make much difference?
