Heat exchange problems
I was talking today to some petrolhead friends about changing the downpipes of my car, but one of my friends told me that the E63 had a chronic engine heat problem, and that I should upgrade my car's heat exchange system prior to any change of downpipes or any other upgrade, specially because I live in Rio de Janeiro, Brazil, a place with very warm climate, with temperatures easily reaching above 110°F during the summer, a winter (if we can call it a winter) which last for 72 yours only, and temperatures staying around mid to high 80s F during the rest of the year.
Any thoughts about all that?
With all your previous experiences with E63AMGs does our cars really have this chronic heat problem?
Thanks!

Yes, we have an inefficient charge air cooling system. Instead of spending way too much chasing minimal results upgrading my the heat exchanger, you're better off adding a water/meth injection kit to reduce intake air temps.

do all year models have this inefficiency? Why would they never correct this

All Liquid to Air IC's suffer from the same issues with heat soak. They are generally more efficient that Air to Air under low load/speed conditions, but once the coolant is hot ( ie heat soak) they are troublesome. While 13+ cars have a split system ( one that is divorced from engine cooling loop) they have the same heat exchanger size and pump. The only ways to solve Liquid heat soak are:
1. More system coolant volume and circulation capacity. Adding secondary coolant tank, increasing plumbing diameter, and higher volume pump feeding a bigger HX.
2. Active cooling like a killer chiller that using AC system to cool a liquid/liquid HX core
Now like chiromikey said, the goal is really to reduce IAT. For high load, or racing conditions, Meth is the only answer for that.
Bottom line for op, Upgrading Intercooler circuit via the above methods will help in 90% of the daily conditions you will see in Brazil, but under high loads/racing meth is the only answer. If you can do both, your set.

you really dont need to worry about cooling on 2014+s unless you are going to a race course and race it hard for long time, or if you are going to drag strip and running lots of back to back runs.... but in daily driving or street racing runs you will be fine

your climate in rio is similar as mine in miami (i was in rio last year to train at Gordo BJJ in Barra da Tijuca), so you will be fine as you have 2014 like me and I log my car and temp is never a problem for me in daily driving and highway pulls.

also, does extra power from a tune make it heatsoak faster than stock?

yes adding power adds heat and makes cars heatsoak faster

You could also go for a trunk tank setup, which will allow you to add ice into the system.

It's a nice kit but for 1/6 the price and better cooling I think meth is the way to go (as long as you don't mind the periodic fill ups).

Meth is good but the cost will creep up if you use quality components such as braided lines, solenoids etc. Granted it will be still less expensive than the AMS cooling pkg.
