In the quest to run cooler on a tight mod budget, I've heard the name "Frozen Boost" thrown around and once I visited their website, I saw the same/similar heat exchangers being offered by multiple Mercedes tuners.

For instance, this 2" core

Air to Water Radiator

And this 3.5" core which hold 59 ounces...

Air to Water Heat Exchanger

Prices are CHEAP and this appears to be a direct replacement for the E55 style heat exchangers...

While I realize it's not nearly as effective as Rob's supercooler, has anyone run these? The 3.5" version appears to be the best buy.

A new vendor on MB World is offering a h/e that apparently cools 50% better than the OEM E55 version for a great price, but still way more than the FB versions (over 60% markup). I asked him if he was buying FB cores and adding brackets, and he plead the 5th... despite them looking identical (same weld marks and all).

I welcome the thoughts of all the gearheads, and vendors alike.

I have the 3.5" thick one. It's an air to air core modified with end tanks, it also wieghs almost 20 pounds. avoid.

 

Very interesting, so you're recommending the avoidance due to weight or poor construction?

Reason I ask, is I was considering a used AMG h/e but this one had a larger capacity.

The 2" thick one should weigh less (slightly) but also holds only 54% of the fluid...

I know Rob's is the biggest and best h/e out there, but it's a bit 'spensive... my mod budget is limited until Kim and I get moved/settled into our new house.

 

It is made of very thick material, I don't think it transfers heat as well as a radiator type exchanger. It's made well, looks good too. It just doesn't shed heat fast enough.

Great info on this FB/China H.E. (wish I had read it before buying the FB).

 

So, based on that reading, this H/E below would be the best bet, right?

ZZPerformance - ZZP 3800 Heat Exchanger #ZZ-38HE

 

I'm not sure water holding/volume capacity of the unit would be a spec for the cooler.....
whereas ...fins/area etc....great.

but volume - no.
Volume would be a "personality spec" as a result of the design.
thicker/less resistance = more volume.

After all - its all gonna heat up in the end (just take longer) to the efficiency of the cooler.
Could almost work against you 'cause if it gets hot it will take longer for the system to cool down - you probably want a low volume quick response (low inertia system).

 

John, I'm also on a tight budget, and went w/ a used OEM E55 H/E from a MB World forum member. When I posted looking for one, had great response from a few of the members there. Paid $90. shipped, for one w/ 23k miles on it. Besides its obvious dimension difference in the pic., it's also thicker. As great as the supercoolers are, I didn't like the idea of covering up my engine radiator. Running straight distilled water and (1) DEI wetter in the IC circuit right now. Don't know if this helps at all; just throwing it out there.

 

This one seemed to work fine for me.

Air to Water Radiator.

 

I'm using the same one as grip grip. Seems to work well for me.

 

Price is definitely right, I'll have to give that one a thought. Which mounting points do you guys end up using?

Thank you,

 

I'm not sure if the ZZP would fit.

 

Yeah, that's what I mean, the thick metal cooler eventually gets hot and seems to be a source of heat rather than a cooler. I've looked into having a radiator shop custom build me a new one to the exact same size. I modded my car quite a bit to get it in there. Quotes where around $600.

 

Has anyone thought of running an alternate thin single plate aluminium cooler along the underside of the vehicle? High pressure drop requiring more amps pump....but potentially thin, light and a large surface in the offing.
Its not catastrophic if it gets holed on a speed hump or something...just a thought...I'm full of 'em....
