Have even a cursory glance through the forums here and you'll see cooling mods done to death. Some may be contradictory, but a larger HE, split cooling, adding a tank, meth and or a Killer Chiller are the options. Typically done in that order and not usually singularly.

there was a pretty good looking one that someone was selling. it goes where the large cabin filter is. I did the same thing with my car. That spot is about the only available spot under the hood that is high enough for self bleeding. I will look for the link and edit it in here.

Well. I couldn't find the damn link. Here is the one I made.. looks very close to the one I was looking for. It took me less than 8 hours to make it and install.
I am NOT offering any service.. ever. to make anyone.. anything. I hardly have time to make things for myself. I keep very busy at the shop I work for.

That is what I thought when looking under the hood for a tank location. What happens to the cabin filter?

95ONE

It just get a paper thin air filter bolted over the hole. Give and take here.

Please bear with me. I have both E55 and SL55. The SL is what I am tuning first. The SL has a 'starter battery' which the E does not. I could build a great I/C tank exactly the dimensions of the starter battery. Can this battery be eliminated?

StarvingArtist

No, it's for your brakes. E has one too, under the air box. Never popped the hood on an SL so just guessing there.

Rocman8

On the SL the battery under the hood is for starting the engine only. Totally different setup than the 211

Thanks again, I am moving the battery to the trunk and getting a tank built to fit in the space. The height means the tank will self bleed. I can ground the battery back there and just run a cable to the front for positive.

95ONE

I don't see how this will work since to lines that go to it will have to be higher than the tank itself. I strongly suggest you keep the battery where it's at and build the tank where the cabin filter is.

Rocman8

He's talking about a 230 chassis. The cabin filters are under the dash.

trabots

In my RHD SL55 the cabin air filter is on the same side as the starter battery. I can leave that intact and still leaves room for a tank. The hoses don't need to be higher. One near the top to take the outlet from the S/C and a low one to gravity feed the pump. I will post some images soon.

you should see around 15 to 20 deg over ambient air cruising no ?,if your real lucky 10 to 15 on a cold day,killer chiller better for obvious reasons ,I went from stock set up ,to extra h/e ,to trunk tank and 4 pumps with a modified intercooler and I'll see 15 to 20 over ambient ,a little better on cold days .

Ah. got it.

Nick - I am using the Bosch 010 pump (hard wired to run whenever the car is on) and have the larger Eurocharged HE. I plan on putting a ~5 gallon tank in the trunk and am curious as to your thoughts on whether I should change the pump or use an additional pump in the tank (I know folks that have done both).

Thanks for your thoughts and help.

You can add anothe bosch in a push pull system or even go with a better flowing pump like the cwa50

Welwynnick

I agree, but make sure you follow cooling system rules.

What about a Rule pump in the rear tank ?

As an interesting FYI (it has been ages since I logged any data in the e55)....My water temp after some mild to moderate driving was 105* with ambient air 67*....So obviously more water + better cooling would be of value....

Hulk

More volume and more pressure. You need both. That's why a 2 pump Bosch push pull or cwa is good
