Water : Air Intercooling

[Nexus]

I never saw 20kw gain with my FMIC. But that's another can of worms.
How often are you on full boost for?.?.? One must take this into account. If this was for a race car, may not be a bad idea. But for a streeter, IMO, just not worth it.

Fair enough. Let's rephrase that then. Any gains from FMIC are due to cooler denser charge. Often we sacrifice some lag time due to volume of piping etc, but the point is that we see gains by cooling the intake charge more effectively.

What I'm suggesting is something that - before we even think about turning on a thermoelectric element - will do a much better job than a FMIC at cooling the charge. In addition it has lower pressure drops and the intake path is potentially far less convoluted addressing the downsides of FMIC.

So starting with an intercooling solution that surpasses anything else at it's job - cooling the intake charge- and what gains might be seen from that, we can then turn on some peltier elements and observe.

If a target BAT is doable, which can be something relative to the IAT, then quite possibly one can gain more consistent responsiveness, a certain amount of additional power above and beyond what the intercooling solution does alone. It may not take that much energy to maintain BAT_TARGET = IAT, and if that's practical, then BAT_TARGET = IAT-5, -10, etc, depending on where you live and ambient temperatures.

A bit of delving into the science of it and could probably calculate how much energy is required to cool the BAT down to IAT...

Actually I have to disagree, this will only work on a street car. Any car permanently on high boost will tax the peltiers overly. Once you start doing that the entire system starts to heat up. If your peltier coolers don't cool their hotside sufficiently at this point your peltiers become heaters at which point your water cooler becomes a heater and you will start to lose performance. You'd also want to be careful with control circuitry, if the peltiers get stuck on and insufficiently cooled they are capable of boiling the water in your W2A system.

Also isn't the gain from an uprated FMIC/TMIC less pressure drop over the intercooler combined with better cooling?
