I used one stock HE and two HE from C32 AMG ( in front of the stock HE)






And here is a additional tank made from a crossmember of R-class.
volume of water: around 3 l / 100 fl oz


I use the johnson CO90 for continuous operation and long water hoses. So I get a total capacity of over 5 L / 170 fl oz.
The IAT is not going over 60 degrees by hard acceleration at a race track.

very nice set up.what is this(additional tank made from a crossmember of R-class)?
do you have another picture for it?
thank you

nice set up

jangy

Damn!! Nice reservoir in the bumper. That is where I wanted to put one that would hold about a gallong. You are resourceful. You have access to old parts? Hehe!!

chiromikey

way to think out of the box! i went to a lot of trouble with my iat cooling mods as well only to confirm my fears that the i/c core itself is the limiting factor no matter how strong our h/e set-up is.

What i am seeing in the front is not a C32 HE, the C32 one is the same as E55, and no way that you can get a 60 degrees unless you are meaning 60'C.

@Robert AMG
This are c32 amg HE! I offer this at mercedes. 60 degrees are the same like 60°C or 140 F.
Believe it or believe it not!

@cls55
The additional tank was made from a crossmember of R-class.

930chas

Wow! That is a great setup! Nicely done..

Hammer Down

930chas, nice run at the track once you get a better tune you will be both quicker and faster cause our cars are pretty even up until the 1/8 where your extra hp kicks in but then we are back to being pretty close trap speed wise. There may be some extra hp & tq lost in early in your run and then loses some again late. What do you think?

blackbenzz

^ Once he gets a real tune the car will be much faster

Might not be too good of an idea to block one HE with others, since you are hindering airflow and whatair does get to the back HE will be warm. Great job of thinking outside the box though

@blackbenz
I come from germany and here are other driving conditions as in usa. We can drive 200 miles at the highway. At a lower speed I have no IAT problems (because of the big water volume) but when I will accelerate a few times from (for example) 120 to 190 mph I will get a big heat problem but not with this setup. At a speed over 120 mph there is a very strong airflow and because of this all three HT become enough cold airflow to do their work.
At lower speed the two smaller HT will work more than the bigger one because they are in front of and this is good enough for lower speeds. It does no matter when the big HT is blocked, because it is still working, altough not necessarily in full extend.
I friend who installed this set up checked this out at "Lausitzring" like "Hockenheimring" (race track). He told me the IAT stayed under 60°C/108 F by very hard acceleration by a long time.

I like the idea.... very nice setup Any chance you can post some data-logging sheets?

lorie

No sorry! I don´t have any data-logging sheets.

Roseylv

wow, Great Setup!

I'm contemplating adding an additional H/E as my current setup is not sufficient.

So, you have your stock H/E + a C32 H/E and an extra tank?

I'm confused, do you have a picture of the crossmember from the R-class?

Rouven036

Nice setup, like the idea with the reservoir from the r-class cross member!

one question, why is the breather hole in the cap of the filler tank blocked by a screw?

mikey33

All this talk about HE's and fluids has got me stumped, but A+++ for effort!

lorie

@roseylv
Yes you are right! 2 HE from C32 and 1 HE from E55 + an extra tank with a volume of 3 L / over 3/4 gallone.
At the last pic you can see the extra tank. It is a modified crossmember of r-class. Of course it is shorter than a unmodified crossmember.

@rouven036
Why?
Otherwise the cooling would streaming out!
In which way you would blocked the breather hole?

This week I will dyno my car again with this mod.

Without this mod it was dynoed with 513 rwhp (172 pulley + ECU)
Here are the results.

ahmad0658

Pulley + ECU tune and you got 513 rwhp? It is really very impressive, I believe usually with Pulley + Tune it is somewhere around 470 rwhp (a little bit up or down) if i am not mistaking.

lorie

The dyno sheet doesn´t lie.
The stock hps at the crank were around 490 hp. Mercedes tells 476 hp at the crank, so the varinace of 15 hp is normally. Because of this, I can take it that the dynometer operates faultless.

This guy programs the curves for Kleemann and Vaeth. Every two weeks he goes to usa and work there for a couple days.

His major task is to tune porsche for the "24 Hour Race" in germany and so on.

I believe the numbers of my dyno a correct.

ahmad0658

My friend, i am not doubting your numbers or your tuner, I just want to know how could you get 513 rwhp with only pulley (not big one) + tune, i am really impressed by that and I would like to have more information if that's the case true to get the benefits myself to have more power on our cars.

I think you clarify your point in the reply above, you mean crank hp and not wheel hp, if that's the case, then you are right and no wonder here about the numbers.

This is a C32 HE(on the left): it is dual pass also not single pass, same as E55 i have the 2 cars.


513 whp!!! there is some magic here.

did you split the circuit from the main radiator?
thank you








thank you

@ecoscope
Please read my last post again and show at the link!
My E55K has 553 hp at the crank and 513 hp at the rear wheels, 600 lft. This is what I wrote.
Beyond I wrote that the first dyno test (without mods) show following datas: 491 hp (crank) and 536 lft. Mercedes specify the E55K with 476 hp (crank) and 516 lft.

So what I mean is, that the first dyno test (491 hp > crank) and the specify datas from mercedes (476 hp > crank) are not very different. No engine has exactly the specify numbers. Because of this I make conclusions that the dynometer shows no wrong / constrained results.

@cls55
Yes I did. The second last pic shows the new extra reservoir.

@robert amg
I quite believe it! But I offer this HE by Mercedes. Perhaps the german cars have other modification as the american cars. One reason is the temperature / ambient air in germany. I know german cars (E55K) use a different thermostat for cooling circuit. Perhaps the HE are different too, means smaller than in usa.

ahmad0658

lorie,

Can you please provide me with the part # of C32 HE?

Thanx
