Before the fender tank, my IAT climbed pretty high on those days, 160° to 182°. I added the fender tank and same type days, it stays in the 132° to 148° range. With and without the fender tank, when I ran the car hard the IAT always came down to a reasonable temp. I went with the fender tank due to the high boost I run and the fact that I bought a FI Interchiller Stage 2 kit and it requires one.

Fender tank has nothing to do with heat shedding which is what the OEM setup lacks capacity in. The OEM setup is also prone to being air bound. Both can be fixed without adding 30 pounds of weight. Take a look at Gabe’s website (Griffin Motorsports) for upgraded heat exchangers and much better hose layouts that fix those issues. Interchiller temps are too cold to properly vaporize ethanol FYI. So if you’re stuck on pump gas than I understand the Interchiller choice but E is superior to an Interchiller.

Also you should look at improving your engine’s efficiency. 20 pounds of boost for 784 WHP is a lot and is driving the heat generated by your blower way up.
