New Heat Exchanger
Hey guys,
I just got done putting a new heat exchanger in my E55 today. I went a little unconventional then most of the setups I’ve seen.
I spent some time with my buddy Chris who owns a small performance shop in Arlington Heights, IL (near Chicago) and we looked over the car, and felt we couldn't really make a really large heat exchanger in the front, so we are gonna keep the stock one, and add a second heat exchanger in the rear by the back bumper. The car has lots of air flow under the car, and room by the rear bumper. we think this should help drop the temps, and add allot more fluid to the system.
The second reason we ran it in the back is we were thinking of putting an ice tank in the trunk for drag racing at some point down the line.
Here are some pics
Please let me know what ya think.

Thanks guys, My budy Chris is a pretty good fabricator. I just thought Id throw it out there.
It is a bar n plate air-to-air intercooler. It allowed us to run alot more fluid. The intercooler itself holds almost a gallon.
I thought it was a neat Idea, and figured some of you guys might like to see it.
Thanks, Bob

That and later plumbing an ice tank will be easy. We already have the lines in the trunk so we can bleed it.

What's the expected weight of all the extra fluid that will take to function? Interesting, but sounds like a lot of added points of failure. hmmm...

Another member has/had the same setup a few years ago but I can't remember if he was happy with it or not. You might be able to find the thread if you feel like searching for it.

The liquid is about a gallon which weighs 8 lbs with the lines I'm guessing 25-30lbs total.
I don't have it hooked up. We will install the pump tomorrrow.
As far as failure points. The cooler could leak, but so could any i guess. We tested it, and it hasn't.
it's only 2 more hose clamps then stock.
2 on the cooler.
Ill let you know if I do get anything to fail

Looks like great execution.
My only concern would be putting it between the mufflers. But even then, if you're moving, I'm not that concerned about convection heat-soaking it.

I honestly don't think it'll work properly due to the large passages that are needed when free flowing huge amounts of air in an air-to-air application. The water in a liquid to air intercooler moves FAR slower in comparison and thus why radiators/heat exchangers always have such small tubes vs. air-to-air intercoolers.
I'd love to see the results though and I'm always a huge fan of people finding creative things to make cars go faster so +1 for you!

cant remember stock but with a meziere pump and heat exchanger the IATs should be around 15 above ambient while crusing.
At WOT IATs depend on the size of the pulley

15 degrees above ambient seems pretty efficient. I don't think you'll get much closer without nitrous, CO2 or something like that

Hey guys I ran the heat exchanger today, along with the new pump. The old pump must have not worked very well, cause the car seemed to have a little more "put you into your seat" action going on after the new one.
I did get an OBD II scanner. The temp outside said 40F on the dash. The AIT was low 80's 83-87f when i would calmly drive around. When I got on it the temps would read in the 160's (166f high) but within a matter of 10-15 seconds it would drop right back down to low 80's again.
Is this consistent with other setups. (i do have a 180MM Eurocharged Pulley.)
I have the coolant running from the supercharger to the stock front heat exchanger, to the pump, to the back of the car into the rear inter-cooler, and then back up front into the supercharger again.
Does the heat exchanger system, and the radiator share more then just the overflow tank? Do you guys separate these 2 systems, or keep them combined?
Are my AIT much different then other systems?
I did go to the back of the car, and feel the inter-cooler. the inlet side did have some heat in it, but the outlet side was cooler. It has to be taking a good amount of heat out of the coolant.
Thanks again for your help guys

One more question. I ran the new meziere pump's relay off of the battery that is under the hood, by the windshield.
Is this a no no?
I didn't get any warnings on the dash, but wanted to know your thoughts.
