…Well this is my IC upgrade..an added and independent IC reservoir that uses 50% MB anticorrosion / antifreeze AGENT (Part# Q 1 03 0002) & 50% distilled water!!

The result is just AWESOME, I have not dyno yet but my car runs all day long consistently powerful early morning 6:00 AM or traffic 3:00 PM 95 degree F ambient same… a gain believe me all day long the AMG intercooler work excellent.

Originally I was thinking to put an additional 3/4 wide radiator (low speed) no that wide as the AMG one just over the stock one, because based on the 82-92 C engine water temperature the IC system need to get efficient, go at Autoban speeds to cool. Now with this new extra and independent IC reservoir the IC radiator at all speeds is really efficient and does a nice job.

Track:
When I have gone to the track, I used to I put ice on top of the supercharger and the water cooling reservoir.....now I do not need it the water engine temperature on the track, hiting the car strong is 90-92 T consant in and now my IC water temperature is no more than 30-35….actually yesterday I went and with the IC and the addition of the SL55 airboxes with filters and inlets I got a full 1/10 quicker on the track…and even more impressive I made 3 runs within 30 minutes .. the engine water T was 90-93 all three runs with identical numbers .....before my IC upgrade I needed a lot of ice and 30 minutes to cool down the system

Installation and photos:

Well, the installation is not difficult and need to modify just one MB pat, get some hardware (Heater hose ¾”, clamps, connectors, radiator overflow tube, etc) no more than $30-40 at Autozone stores + SLK230 reservoir (A170-500-06-49), radiator cap (A124-500-04-06), MB antifreeze, and distilled water $80-90, so total $110 to 130 so far and 1-2 hours to install and modify the SLK reservoir… really strait forward 5-10 minutes.

Of course I Thermo-Isolated the SLK reservoir:

wow!! you are so good with all those DIY mods... wanna come to Cali and build something for me??

Pierre: This exactly what we do in our ODPS kits. Instead, we use stock C32 windshield washer reserviour for factory look.

Stock cooling system for the intercooler is simply inadequate. By adding extra capacity car becomes a lot more consistent.

Here is the link to earlier R&D posts. R&D

Pierre32///AMG

..Vadim this in not exactly that you do with the ODPS kit...same concept and idea but different way, for example:
which kind of water do you use in the ODPS kits?

Beside, I am interested on the Garrett core with Laminova cores that are more efficient (90-95% vs. 70-75%) and less restrictive that you are testing..

Thanks!

Vadim @ evosport

Pierrse: It is the same idea and the concept IC does not care where the cooling medium comes from. You have added extra capacity to the IC cooling circuit. This is exactly what we did over 6 months ago. However, we have added 6 litres, where is SLK230 reserviour is less than 4 litres.

We use windshield washer fluid, since it is a mixture of soap, alcohol and water. It is far superior in cooling than antifreeze.

New intercooler with Laminova cores is finished, I will post some pics and data shortly.

Pierre32///AMG

Good! New intercooler with Laminova cores

Yes, you are right the SLK230 reservoir is not bigger than windshield one....

but Vadim,
for me is really had to understand and believe why windshield washer fluid, since it is a mixture of soap, alcohol and water is superior in cooling than anticorrosion / antifreeze AGENT with distilled water.

First, just water has minerals + soap and alcohol thermodynamically does transfer temperature quicker than without those elements. Distilled water has no minerals.

Second, the IC pump and the system itself was made to work under MB anticorrosion / antifreeze AGENT with distilled water (50/50), which has a totally different density and fluid performance than windshield washer fluid, with soap, alcohol and water.

Lastly, if you do not use distilled water (no minerals) with the respective anticorrosion there is a high chance to damage in a long term the IC system. Why, very simple accumulation of minerals incrustation (tartar, fur) in the IC radiator laminas and pipes for mention ones

Thanks!

Man you guys are Teck nerds..LOL
Keep up the good werk....

scmguru

Is the SLK230 reservoir a windshield or coolant reservoir? What is the purpose of the modified windshield filler?

scmguru

Vadim,

Are you ever going to sell the intercooler capacity upgrade separately? I'm sure many of us would be interested?

Also, from what I understand doesn't your system just add 6l of capacity? Is this capacity isolated? From what I understand, Pierre's system results in essentially 2 closed cooling systems, one for the engine, one for the intercooler. Is this correct?

Pierre, could you put together a step by step w/ pictures for those of us who want to give this a go ourselves?

Thanks

coolant reservoir

COOL DIY

Vadim @ evosport

Pierre:

1. The soap in windshield washer fluid acts to reduce water surface tension. Same principle as in RedLine WaterWetter.

2. Since windshield washer is still functional, fluid gets periodically refreshed.

3. Since the fluid temperature never gets close to boiling, mineral deposits are very unlikely.


Michael:

1. At this time we do not have plans to offer IC upgrade separately.

2. Our system is also closed and isolated from the engine cooling system.

kenny

By adding the 6 liters to the cooling circuit, the end result is delaying the onset of heatsoak in the cooling system but you fail to mention the downfall which is that more coolant requires more time to drop in temperature again once it heats up.

Pierre's separate cooling circuit for the intercooler, while very similar to the evosport solution is superior in that it keeps both systems isolated from each other. It should work better, even though the added capacity is less than 4 liters.

Now, the new intercooler itself that you guys are working on should hopefully bring more power gains

Vadim @ evosport

I thought I made this very clear. Please go back and read R&D posts.

SteveL

If you are in a non freezing climate, Florida/California, a completely separate reservoir, not shared with the windshield washer or engine cooling system just using distilled water and water wetter would provide the best performance. However, it may not be all that measureable over the the Evosport setup. But you certainly wouldn't have to worry about it running low when you wash your windows.

c32brabus

you both came up with excellent ideas to cool the intercooler. I like both but i have to say i'm not too crazy about soap water cooling.... alcohol is a different story.

bverotti

Sure, I guess in racing conditions the 6 l would heat up and take longer to cool down. But we drive street cars and not race cars. It would be interesting to see how long it would take for those 6 liters to heat up and what temp it gets. Vadim, maybe you have some data on this ?

Anyway the guys from Evosport really did a good job with the increased cooling reservoir. Even the guys from MKB gave it thumbs up!

Is it possible to see the temp off the S/C ? if yes please instructions.

MiamiAMG

lol, i was thinking the same, but without them we would be lost!! Dont ever stop guys!!!!

Finnish C32

Hey Evosport ppl there is MANY guys in E55 forum missing you guys

Kar don

umm isnt the C-class windshield washer tank heated by the cooling system. I think MBtech said this himself.

Vadim @ evosport

Ok, lets see if I can some of the questions:

SteveL:

One of the parameters we were shooting for in our ODPS design, was to keep it as stock looking as possible. So an any kind of external reserviour inside the engine compartment, that is not stock, was not an option. Also there is no room inside the fenders to fit any additional containers. So converting windshield washer reserviour made the most sense.

"Low fluid" warning light will come on when one still has 3 liters left. Remember it is still 2 liters more than factory setup.

C32Brabus:

Water with RedLine WaterWetter (soap) is used by many road and club racers for many years, as it offers the best cooling.

Bverotti:

It will take about 10 minutes at WOT to get enough heat into 6 litres to where it is becomes a concern. With stock setup it was less than 2 minutes. This is data from running big track at Willow Springs.

Finnish C32:

We are working on SL/E55 kit, stay tuned.

AlBoston:

There is an electical heater inside the bottle, however the water coming from the intercooler is warmer than what the heater is set at.

Pierre32///AMG

Based in chemfinder.com and the alcohol in it is methanol.....
just for your info the alcohol in the winshield washer fluid has a boiling point of 68C.
