Installed: Custom fit Auxillary Heat Exchanger
As mentioned in another post; looked long and hard to find a H/E but none made for this body style. All aftermarket are just to wide, even the E55. Good news, never had to remove the bumper to do the install.
Found a Garret H/E that would barley fit at 26" wide X 6" tall and 2" wide at the tanks. The cooling fin area is 1.25 thick but end tanks are 2x2x6 and total system coolant increase came out to 40 ounces. This should net a total H/E coolant capacity of around 90 ounces, excluding coolant in the Intercooler under the blower.
Pic 1 is the CL style H/E . Pic 2 is the S55 H/E with small auxillary front H/E. Pic 3 is the Garrett h/E in lower valance area. Pic 4 is before install (note oil cooler and brackets blocking room).
I hope some of the coolant experts chime in, as I have some pump flow questions and would like to compare data log info.. I have some early test run results but waiting for it to warm up for peak numbers..
PS, I left custom brackets and bolts un-painted for pictures. Painted and installed valance grill back for a stock look.

Data logged today, as ambient was 78-81 deg here. Nice and warm to give above average effeciency results.. Drove 34 miles testing the auxillary H/E.
Start up was from ice cold. Took about 7 miles to reach 170 engine temp and 97 IAT. Made the first run from those temps , with a 25mph roll to 100mph. Iat hit 142 peak . Recovery was so rapid , that in only 6 seconds was back to 102 deg and a few more already at 96 deg.
Drove all hwy speeds to next spot and IAT`s still stayed in the 15-17 over ambient. Next run, was from the same speed but engine temp was 185 range. Iat on second run, hit 152 deg. but again back to 95-97 in under 10 seconds.. Very nice compared to stock recovery and peak.
Results verses past stock runs. Stock , I would easilly see 170IAT at those speeds. Recovery was in the 20-30 second range and driving IAT average over ambinet was 27-32 deg. The largest gain, was in recovery , which really helps for drivability. Peak IAT is the on going challenge.. It seems the extra capacity is helping peak IAT by about 30 deg..
Here is where I have some questions and could use some feedback to improve peak iat`s. If we /I have a 100 ounce system, then for an average 12 second boost run, wouldmore pump flow help peak IAT`s?? My pump roughly flows 30 ounces in 12 seconds (5.2 GPM). The water is heated to fast under full boost, that itwould seem better to flow the whole 100 ounces during a 12 second run.. Any ideas? Adding more capcity at this point , seems like it won`t help much.. How do these numbers compare in 80 deg temps?

Adding to the previous test: Made four 28mph to 110mph runs and never saw IAT`s go over 124 deg. Ambient was 60 deg. Since the last runs, I corrected a kinked I/C pump inlet hose with a new molded 90 deg. hose. Flow was restricted from the earlier test but also 20 deg. warmer. Recovery is so fast now , that on four back to back runs, IAT`s still stayed very consistent and never over 124 deg.
Based on data logs , I am only doing aux H/E, PTE T stat, and not seperating the system.. Coolant mix is 1 gallon coolant, distilled water and 16 ounces of water wetter.. I plan to add a larger I/C pump and that should be it.. 10C fan mod comes with the tune, so that is a given. Goal is to run 1/4 mile and not hit 140 deg. IAT in 70 or below ambient. I feel the above recipe has me there..

I bought a garrett H/E off Ebay for $125.00. It is smaller than the aftermarket E55 H/E`s but was my only option.. 40 ounces , as an aux. is working well though. No one made an h/e to fit the w215 class, so had to improvise..
I think the root of the information and test, is that adding a large H/E and T stat can make a huge difference in day to day performance.. Yes, been said many times before but always nice to see some added data logs/test..Total system capacity is around 80 ounces now. My bosch pump works really well but confident a larger pump will help peak IAT`s even more. I assure you, that when you hit 140 deg. IAT, you lose around 9 deg. of timing.
