Yeah i decided to use the fender tank instead of the trunk tank only because it was a challenge.. lol.
Basically it will take longer to cool the loop with the added volume, but this is good because while it takes longer to cool down, it also takes much longer for it to warm up.
You can think of it like this, instead of the end of a 1/4 mile run the MAT temps being 120, they'll be 110 with the added volume instead of just chiller only. This is just an example. Then at idle, low speeds it takes just a few minutes for the coolant temp to bottom out. Its amazing because you can sit and idle, MAT temps can go up to 120F, you blip the throttle and it immediately drops 30F. Soon as that air hits the freezing cold bricks from opening the throttle its instant cool.
Also remember the chiller is always fighting the heat from the blower sitting on top of the heads so its always absorbing heat.
It sure beats trying to cool it with air/heat exchangers. You can only cool water to ambient no matter what you do.
The fender tank is out of range of heat where it sits behind the fender. The coolant is close to freezing most of the time.
