Im glad you mentioned that as it does make sense to just remove the Hx if its going to be a mostly track vehicle. all that thing would be is a big hot sink in front of a engine thats not moving at the track..
But i think i will sorta disagree with the pump thing on a DD, if on for a decent amount of time its bound to generate some sort of heat, esp in the summer imo..

 

yeah that is a good idea eiter removing the the h/e or making a couple t valves you could turn to bypass the h/e

 

hadnt thought about that, i guess its something i can test out. itll be my DD so the HX will for sure stay, but i might want to bypass it at the track like you said Kyle.

hell, i guess i can just play with all different routing ideas and see which results in the lowest IATs

 

You make heat when you compress something, Water/air...what ever. Turbos don't make heat when there not boosting, only when you compress air does it really get hot, same with water. I would put money on you put a temp sensor before and after the pump, there isn't 1* of temp difference even after driving all day. There is no real pressure in a A/W system, only water movement. The pump on the stock Maggie system is at the very bottom of the reservoir tank.

 

Im not saying a huge difference, and yes i know anytime you compress something it causes heat.. but i would bet somewhat of a difference if you did nothing but pump water thru rubber lines for 30 min(in a running summer engine bay) there would be somewhat of a difference(maybe 5-10*) even if it isnt compressed, disturbance/electrical movement over time does make some heat..
which in the end all this talk isnt really worth it like your saying when in combination inline with IC, Hx, and def a ice cooler..
I was just saying even a non compressed electrical pump will create heat overtime..

 

Try to locate the pump in the warmest fluid location in the system. This will maximize the pump efficiency.

 

the ice boxes you guys are using. are you actually pumping the ice water around or do you have a copper/alum coil inside that the ic fluid goes through surrounded by the ice water. in effect being a heat exchanger. just thinking the coiled setup could be a quick and easy water change at the track without worrying about removing or adding to the sealed system. sorry if this has been covered a ton of times.. just a thought i had while reading this.
