Larger air to water heat exchanger options?
Hey guys,
Was discussing the topic with a friend last night and i tried finding units online. Seems like nobody has offered anything for our cars. Is there a solution out there? I was able to find a lot of options for the F8x M3/M4 but not a single one for our cars. Has anyone does this? Why hasn't anyone does this? I'm guessing cost is a huge driving factor? Or am i the only one that wants this mod? I can see a performance benefit with something like this, with all the turbo upgrades and guys pushing the limit on these cars; naturally you'd think this would be done. Thanks -R I'm referring to these units. |

Is there room? How much more fin area would you need for a worthwhile temp drop? Even with your intakes there isn't much space up there. But, I suppose someone who was going to go for large HP wouldn't mind rearranging things as much as possible.

I think most big power owners are just using meth to help cool things. It IS pretty tight in there.

That maybe BMW's name for it, but in the real world that is the Air2Water intercooler. The actual "heat exchanger" is mounted on the front bumper (iirc its the flat mounted radiator) to cool the water/coolant down that is being used to cycle through the intercooler.
Before even modifying/making new ones I would def. figure out a way to upgrade the heat exchanger (radiator style) to something more efficient and find a way to make a LARGER Water tank, almost like allmotor_2000 did on his car. The problem at the end of the day even if you upgrade the intercoolers you are still stuck with a subpar heat exchanging system and a VERY small water tank. I am going Air2Water on my Porsche right now and I have a 8 gallon water tank that feeds the intercoolers in the back and on their way back to the water tank they go through a radiator to help cool even more.

I'll take a look at the heat exchanger on the front of the car, see how much that can be enlarged, i think increasing the surface area of both units as well as the liquid capacity is the ideal system. I just wanted to see if someone has looked into these units and what options we have out there. Sounds like the answer is none. Guess i'll get busy. -R |

Raza I'd def. look at possibly finding maybe a space for a larger reservoir for the Water/Coolant as well. Having something we could put ice in and drain in between runs would be awesome.
I still see that being the major limiting factor. I know on the 03/04 Cobra, Shelbys, etc. it is a huge upgrade to do when the front mounted heat exchanger is changed. Most people usually do an ice tank in the trunk, but with split intercoolers like on the M5 I think plumbing is pretty detailed to make it all work (at least in regards to connecting it to the stock plumbing).

Just running 5gal more water made a big difference. There are three heat exchanges for the charge cooling system and they work reasonable well unless you are in stop and go in high heat.
Of course ice solves all problems :-) I have tested the IC's for pressure drops and they work fine. Could they be improved to cool better... sure! |

Think this will need to be a multiple approach to work, larger or efficient intercoolers (hopefully with less pressure drop), larger more efficient front radiator and larger volume of coolant to release gains. Even then it will not prove much of a benefit on the road but drag or road course events where heat soak is a problem ther may be a gain.
Lets see what Raza can come up with. |

Many of us will champion this effort through purchasing a unit upon completion. I remain in awe at the propensity of certain posters to not just litigate distinctions with little difference, but to do so from a position that entirely neglects basic engineering and physics principles. Thermal energy can be exchanged between virtually any physical system. Whether the mode is convective, conductive or radiate has no bearing on your hypothesis. I'll end the rant now
