That's what we thought initially but we switched the flow direction and took out the thermostat at the same time. So the issue might just have been the thermostat only. I do have the Jackson racing dual radiator and oil cooler and it is much thicker than stock.
I also have the fan shroud made by JDL with the biggest spal fans available and the two pushers are spal as well. I had the pushers installed because of the turbo intercooler I had before blocking the air way and in the summer the AC was having a lot of issues due to the condenser not able to dissipate the heat. I might take them off now but I don't think they're that much of a restriction.
Anyway, heat is not an issue at the moment I might switch the direction flow one more time without a thermostat or with a lower temp one to confirm the direction is not an issue. Also it will look much cleaner.
