I have MSD temp switch, 82 thermostat, alloy airtec rad, airtec front mount I/C, 2 spal fans on the rad and other one behind the rad as sucker. Also stage 2 not water cooled T3. i have the same problem. i think the problem is from the I/C. I was thinking to try put the I/C lower with some way... or to put a turbo cooler in the water cirquit...
