Mikey, now try it with some ice.

[QUOTE=chiromikey;2331769]here are some quick pics. i won't have any time to get any data logging numbers until after the weekend but i'll share my set-up anyways.

basically a 3 stage system consisting of a new front mount heat exchanger with 72% more capacity than the oem unit, a trunk mounted reservoir to greatly increase capacity and give me the ability to add ice at the track to REALLY help cool the charge air, and what's that hidden behind the rear bumper cover you ask...why that's a second remote mounted heat exchanger with dual 6" fans for good measure. as you can see there is a second johnson cm30 pump mounted at the reservoir with it's twin brother mounted in the stock location. there is PLENTY of flow with just one cm30 on this system but i'm obviously into overkill. after seeing how much water was flowing, i really think the cm90 is too much. and of course, the i/c circuit was separated from the engine cooling circuit.

this is a test system to measure benefits and possibilities so i didn't go all out on hoses or connections. each stage of this system can be duplicated or used separately so the possibility of a "kit" is being tossed around. as i've mentioned, this system may not be the ultimate like vrus' slr system but i'm expecting it to work well.

btw, a very important criteria for me was that the heat exchangers be true bolt-ons with no cutting of bumpers or brackets so the car can EASILY be returned to stock. the only permanent mods are the holes for cooling lines to the reservoir which can be plugged if removal is necessary.


Mikey: Did Chris build the system for you? How much did it cost?
Absolutely looks great and seems to perform great too!!! I may get it too if Chris built it for you! Regards

The stock one is like the evo it is a double pass design. A single vs double pass can be argued back and forth. From my understanding by having a higher water velocity a dual pass will tend to work better. If you can increase flow then the single pass can work better.

Very nice Mikey!!!!!

You really took advantage of the real estate.. LOL... That rear mounted setup is pretty trick also!!

who makes the radiators ?

Interesting. A second remote mounted heat exchanger behind the rear bumper...

chiromikey

i believe they're tube & fin but i'm not 100%.
will do and i'll report back asap.
yes, chris built the system. he's considering packaging a bolt-on stage 1 cooling kit with the front mount heat exchanger and parts to separate the i/c and engine coolant so i really don't know what his price will be. lets just say that if he does, it will most likely be significantly cheaper than anything else on the market.
they're pwr cores with custom end tanks, inlet/outlets, and mounting brackets.

Excellent, That is a marked improvement! 120v160. You should be proud.

Good to hear that the recovery is much quicker, Mikey what was the "pump on temp"? And did you let the ECU control the pumps & fans or did you have them on manually?

Ice & manual pump switch = prechill entire system, killer first run.

chiromikey

these runs were with the ecu controlling everything...no manual override. i have no idea what temp the ecu turns on the i/c circuit.

...and yes the manual override switch will be put to good use in the staging lanes!

Please let Chris know that I am serious about purchase his bolt on cooling kit. If he needs a good faith deposit, please have him pm me. Thanks.

stevebez

Thunk the 03's had the pump on more often than later models ... will check my '06 when my stuff goes in.

E55 RUSS

Yes I wolud intrested if the price is right...Can please let ME all the details as well...


Thanks...

chiromikey

he's considering putting a kit together if there's enough interest. anyone that might be interested please pm me so that i can prove to him there IS enough interest for him to do this. more people willing to build stuff for us will push all manufacturers to offer better products at better prices! if there's enough interest i'd bet i could even persuade him into getting with mbworld to set up a future group buy (probably at half the price of anything elso on the market!!!) so let me know asap!

mercixus

Great post and nice work! I have a faulty IC pump and is thinking of an upgrade.

Ghostrider

Chris is the man!!!

Mikey I leave for a while and you are cooking up your own mods again. Way to go buddy.

Gotta love AZ in the summer.

chiromikey

where ya been? playing with your new toys i assume.

this was a mod out of necessity because of the heat around here but it was fun none the less!

Mike:

Very nice job. The work looks first rate. Can you feel the difference in our blazing heat? I know my SL55 is down on power in the summer.

chiromikey

thanks dean...and congrats on becoming a site sponsor.

i do feel a difference. now the car doesn't feel like it's missing 100hp because of our summer heat nor does power tend to drop off after a run or two. however, i have no faith in "butt dynos" so i'll get some real proof when the weather gets closer to my last dyno run. the datalogging comparisons are promising so i do expect to show some hp gains.

Jrocket

When are we hitting Speedworld? I'll make the drive out there,just give me some notice.

chiromikey

i'm jonesin' to go but it's just too damned hot right now and i wouldn't want you to make the trip out here only to run more than a half second slower than you're expecting.

SLK55R

Maybe I could get one to switch out the additional heat exchanger I have from renntech. That thing looks like its much more robust than the stock heat exchangers on the 55k's.

turbineexpert

I'm interested.

theboogers

i would like a front unit for the sl55 if it is available.
