It seems like most of the people that would be interested in this have either been prototyping, or otherwise been in the development loop. positive feedback from some recognizable names already.

I was surprised that it would bring down both water and oil temperatures compared to the factory oil-to-water setup. My only explanation is at by the time the coolant goes past the main rad into aux HX, it's already close to ambient. So this would have a higher temperature differential which outweighs the reduced heat capacity of oil. thus, there's more total heat rejection flux out of the block

Im extremely interested in this, but concerned about removing an aux cooler.

Any updates on this? I know Verus released a Q&A on this and an install video, but deleting an Aux cooler when coolant temps already get pretty high sounds sus. Obviously the heat from the oil is playing a roll here, and separating the systems sounds reasonable, but I wonder if there’s still a better way.

I'm interested In more info too.

the verus cooler is so good that a lot of cars have to actually adjust their temp targets to not run too cool in a lot of conditions.

Im mainly looking to help lower IATs, what's the best option, heat exchanger or the oil cooler.

neither will have any effect on iat, and youre doubly wasting your time trying to lower it spraying meth with a wagner im

Are you implying that the effect won't be significant enough to matter, or that there's no impact whatsoever, even in theory? Referring to a heat exchanger not having an impact on IATs

both, with a net increase in weight to your front end and a net loss to your wallet

Heat exchanger doesn't do much, in fact sometimes makes things worse, unless you also upgrade/add a water pump to be able to take advantage of the added volume.

Spraying meth/water combo, even with an upgraded manifold will help intake charge temps 100%. Not sure why anyone would say it would not. Literally proven.

I definitely see my IATs drop on pulls with meth. I've heard lots of people talk about only seeing 10 degree temps over ambient with different manifolds, but not posting data as extensive and @razorlab . I stay pretty consistent at 10-20 degrees over ambient doing pulls until I hit heat soak and see around 30 degrees.

I think you interpreted it wrong. I was saying it was a waste of time trying to lower temps with a heat exchanger if he is already spraying water/meth.

Lower IAT is lower IAT. Not a waste of time at all. Even with an upgraded mani-cooler, it makes a difference.

It's less about the ambient temp delta and more about the heat shedding ability of the mani-cooler and/or meth/water spray.

Charge temp before throttle - IAT = heat shedding.

Of course, if you are using meth/water spray as well, you need to inject it after the charge pipe temp sensor in order for the the above calculation to be correct.

Example on my car. From the first lap to the last lap, the heat shedding stays pretty consistent.

First lap:

Eleven laps in:

Sure, if a heat exchanger change did lower temps, which it doesn't, while spraying meth. You're already below ambient. If anything, in that situation a larger reservoir of cold side coolant would hurt temps as it is fighting the meth evaporation chill.
