Sneak Peak Heat Exchanger
I had NPI fab me up a bigger primany heat exchanger and a additional secondary heat exchanger (since the S600s dont come with the additional one up front)
Front the pictures you can see the primary one has about 45 to 50 percent more capacity that the stock one. And with the additional heat exchanger in front the total capacity will be close to 100% more than the stock system and with additional cooling surface. All the heat exchanger cores are a tube and fin design which is the best for a water to air cooling application.
I dont have any pics of the secondary additional heat exchaanger as of now.

Primary unit fitted now he is working on the secondary unit in front, since the s600 only came with one unit.
In additional to this we added a fan in front of the small radiator in the passenger side wheel well, the shroud was present but no fan.

More pics
Attention to detail, a small bracket was fabbed up to accomodate the stock rubber grommets, I dont like using zip ties etc etc
Since the 600s didnot come with and aux fax, we decided to add one since the shoud was already present.

Looks very nice. :-)
A couple of questions
1) Is this a custom made intercooler or a "standard" element made to fit?
2) What signal/power do you use to trigger/drive (run) the Aux fan you mounted?
3) Would a small Aux fan (like one from a motorcycle) in front of the extra intercooler be an idea?

1) Is this a custom made intercooler or a "standard" element made to fit?
Both the Primary and the secondary are custom made from new cores. The 600s only have the thin heat exchanger between the radiator and the front bumper, so we made a bigger one and also added a secondary unit in front bu the bumper support.
2) What signal/power do you use to trigger/drive (run) the Aux fan you mounted?
We used a switched 12v power source from the ECU box in the engine, bay. I can take pictures of the wire.
3) Would a small Aux fan (like one from a motorcycle) in front of the extra intercooler be an idea?[/QUOTE]
It would help a bit when the car is moving slowing or when you race you are in the staging lanes you can trun that fan on. TO be honest I dont think it will help that much.

Nice work.
So I'm sure you logged IAT in normal driving with your stock setup. I'm guessing you saw about ~50* above ambient when (IF
) you ever drive "normal".
What are you seeing with the new setup?

BOR my iats while crushing on a 95F ambient day were 150 to 160. They would drop to 135 when I start accelerating.
I have still not got the car back, will keep you all posted with the after new setup iat numbers

Professional job done by NPI, car was delivered to my place.
I am still running a stock Bosch pump, yes I know I should have changed it while all this was done, but I wanted to car back.
Ambient temp was 98F
Driving around in traffic IATs were 143F. I parked the car for about 10 mins and got back to driving the IATs were up to 165 but dropped to 144F in about a minute of drive.
When I rolled into the throttle they would go down to 129 and stay there still about 110mph at 125mph they were 135F. I plan to install a Meziere WP136 pump, it may help a bit. Inputs?
Please can you all post your IATs number so I have something to compare to.

That's a lot of cooling! Can you give us the core dimensions of the two HE's?
I have a Eurocharged S600TT with a stock HE (for now). We're having the coldest and wettest summer on record in the UK this year, but I'm still seeing around 140 cruising. It drops to just under 110 after a few seconds WOT, but I can't do it for any longer (presumably until I change my coilpack). I had been wondering if that's normal behaviour, but I guess it is.
It sounds like the IAT is affected more by the general under-bonnet temp than the ambient temp.
Now your car's back on the road, could you post a pic of what it looks like from the front with everything back on?
Great thread BTW. I've read a lot about cooler upgrades, but very little to quantify the actual benefits. I'd expect the Meziere to make a significant difference.
Cheers, Nick

This morning ambient was 87F and after start did a roll in upto 110 mph and IATs were 102, yes these numbers dont mean anything since the car was not heat soaked. I let the car sit for a while and did another roll in and the IATs were at 127F

Looking good, keep posting updates.
Have you thought of doing a trunk tank or any other extra water storage ? The window washer water storage tank is very large on my CL600 and I never use it, I was thinking it might make a good water storage tank for the HE, what do you think ?

The windscreen washer tank is an interesting idea. In the S & CL its already heated with engine coolant, so there's a heat exchanger pipe in there already. Its not a long or large bore pipe, but its water to water, so its efficient.
The washer tank is 6.7 litres, which is on the small side for an ice box, but it is already there. I prefer to keep cars as close to stock as possible, and plumbing the washer heater into the charge cooler circuit instead of the engine coolant shouldn't be too difficult.
That way, it will do the job of a cooler reservoir and a windshield washer at the same time. I'd rather keep anti-freeze in the charge cooler circuit, and keep that independent of the washer reservoir. And there's nothing stopping you loading it with ice for the odd visit to the drag strip.
I think the charge cooler should provide plenty of heat to keep the washer water warm, while adding an appreciable amount of thermal storage to the charge cooler. Its not 4 gallons, but its a lot more than whats in the circuit already.
Nice idea, Nick

I noticed lower IAT's and faster recovery on my S600 after changing out my charge pump to a Johnson CM30... I kept the stock HE on the advice of my tuner. I know local guy w/ a tuned 06' S65 w/ a trunk mounted aux cooling tank and he swears by the Meziere charge pumps. But on a hot day at the track he had trouble getting under 12.3.
After all of the research on cooling a V12TT over the last year and a half, I have come to the conclusion the only way to truely increase/maximize power from heat soak is bigger intercoolers.
The other stuff helps, but bigger intercoolers changes the game.
I am amending my original statement after reading something BenzOrama just posted. Meth is the other way to totally maximize your HP/TQ.

Sure why not if your buying....Even so despite being doubled in number compared to stock the internal surface would still be less than one long coil on each side. Also the quad setup has to have some turbulence as air is entering from all 4 sides trying to make its way to the throttle body. Lets be realistic, of course it works for them since they have modified turbos and a larger displacement to power thru. Also I would be really surprised to think they don't suffer heat soak on heavy back to back pulls in 90 degree weather. In the end, I would agree it must be better than stock but at a cost where improvements are worth gambling on.
