Interesting I'm running just Mercedes-Benz coolant through the system. I was under the impression that distilled water will evaporate. Maybe good for quick track runs if you drain it right out after and refill it with ice and distilled water but for daily driving?

I run only distilled water through my IC
Nothing cools better than water

I know some that add a splash of coolant for anti corrosive properties

I am starting to wonder if I would have been better off keeping the HE with the KC. Maybe if the AC can be programmed to say on at WOT or if I had a 5 gal tank instead of my 2.5 gal tank. I would have more water for one and also I would still have something to help with IATs when the AC shuts off.

I did get it to spike to 135 ish and it wasnt all that long of a run. I believe it was 0-115 range. I dont think I let the water totally cool on that run but still. I had it running at 65-70 IATs going uphill today and a quick blast from 35 to 75 it peaked at 125 Seems to just heat up so fast with the AC not cooling the water and no HE to help once the water heats up.

How about putting the HE on the hot/outlet side of the supercharger to bring the temp down before the KC, with a bypass loop around it once your temps come down. A termostat or some kind of temperature switch to block the HE. Best of both worlds.

gaspam

exactly.... also if you ever want to run a mile event the KC alone will not suffice.

and if your AC ever fails (what MB ac fail? no way! ) then better hope your ECU pulls timing quick enough and you go into limp mode before any detonation occurs

i think the kc is great for city driving and such but just not for long stints of wot... need a fail safe for that and HE currently is that.... plus it only raises iat 15f according to KC

ArmoE55

So KC + HE raises the temps only 15F? That's nothing. I'd rather keep the HE, it looks cool

More please, So i can play too

Sac is about 2.43 mph low last I heard, so in case of the 10.98 it would calculate to a 127.74 which sounds about right with our cars and on my 10.88 it would calculate to 129.43 which also sounds about right.

What was your 1/8 mile speed & et?
What PSI did you set your MT's?
How did you launch?
What was your suspension setting?

I have an AEM water/meth injection kit. Dual nozzles that spray on both sides after the tb. Simple control modual that is set at 11psi and full spray. Yes, M1 and water is a great mix.
We already had the tune for the mods and fuel (both 93oct and Q16) and all we did was add the meth. We never retuned for it. It was only for cooling. And it worked. After a 4th gear pull to 184mph, the surge tanks would be ice cold to the touch. And the water in the trunk tank was 69 degrees. Did a back to back 4th gear pull and the trunk tank temps only went to 79 degrees. all in 92 degree weather (average for south FL).
I also have a Cobra HE mounted under my trunk to help cool the water before it goes back into my trunk tank.

here's a pic of the trunk and Cobra HE

Why under the car and not up front?

Size and surface area I'm sure. Not always about air flow to drop temps larger surface area will cool it just fine with the air under the car.

RedBullJnky

I have a Eurocharged HE up front.
Exactly!

gaspam

do you have pics of the nozzles installed? and what size nozzles are you running?

i have been interested in doing this on the e55 but cant find much documentation on the setup and nozzle placement was pretty important on my audi S4 since too far up the y-pipes would cause pooling and I would see timing pulled (although i was tuned for meth and timing advancement)

RedBullJnky

I'll get pics and sizes for you tomorrow.

forcefed4door

so with the kc setup you also need to run the ac? isn't the compressor gonna gobble some power?

gaspam

sweet! appreciate it bro

RedBullJnky

Never a problem.

black06c230

I'm sure some but when it's 90* out and your IATs are starting at 60* instead of around 100* you have effectively gained 40hp. General rule I have read is 1hp for everyone 1*. And you aren't really gaining power just it will be like driving your car on a 40* day.

PACougar

The compressor shuts off when you go passed a set throttle percentage, so no you're not going to lose any power.

RedBullJnky

Sorry! Best pics I got.

Hey Jack, sorry I didnt give you a heads up, I didnt decide to go until that same day and only had time for 1.5 hours.

Trap was only 95.5 MPH in the 8th. I think the 8th mile might be high if I remember correctly. My GTO was trapping 97 MPH at the 8th and only 117 in the 1/4. It should be a solid 24-25 MPH back half on that car.

So my 1/8th was 7.6-7.7 @ 95 MPH on my 11.8 and 11.9 passes. What was very interesting is my MPH in the 8th stayed the same all day at 95 MPH. My 1/4 mile trap went from 121 to 119 down to 116s the last 5-6 runs. . I think its safe to say all my timing was being pulled in the back half from high IATs. 26 MPH down to 21.5 MPH in the back half. Water was cold enough first part of the run and then I fell flat on my face the back half.

MT were at 18 PSI at first. Later I set them to 22 and did better. Had it in sport mode and was power braking to 1200 RPM. Suspension I set to normal and also tried the other settings but they didnt seem to help or hurt things. I now know that I shouldnt be power braking. In fact with my chiller it was probably raising my IATs before launch. Man I wish I had my scanner . It would have helped so much to know what was going on. I just thought I was golden with the chiller.

Had my IATs down to 48 degrees yesterday with 65 degree weather. Punched it from 30 and ran it to only 85 MPH and it went from 50 to 160 ! Damn ! Its not like that was much time at all to get that high. The IATs do recover very quickly though. Within like 2 seconds they are back down to around 90 and maybe 5 seconds they are back to 80 or 70s. I need to actually log some runs to really see the time frame but I can tell you for sure it dropped from 160 down to 100 in a couple seconds. Basically as fast as I looked down at my gauge after the pull it was in the 90s.

The guy who installed it on my car doesnt think the water really had time to heat up that much. Instead he thinks it could be insufficient flow to the IC and it cant keep up or just the crappy IC design cant keep up. I just have the newer model bosh pump which is like 7-8 gal flow. Thinking about getting a 20 gal pump to see if it helps much.

Your tune may be off as well when I was stock I was running 93.5 to a high of 94.2 in the 1/8. My best runs came with that setup I sold you at 20psi before the runs with a 1.71 60' launching off idle. Your car if running correctly should pick up about 27+mph in the back half......our setups are similar but I'm 8 tenths quicker in the 1/8 and about 7mph faster and around 7mph faster at the 1/4.

When you go back to the track set your psi at 20, raise your suspension, turn your shock setting off and get a nice burning going with you rolling out hot and then power brake just long enough to take the slack out of the suspension and then let it go back down to idle and when you are ready after the light turns green very quickly step on the gas at the same (almost) time let your foot off the brake and if you don't run a better time with a better mph then you may have to look at your IAT or your tune.

RedBullJnky

Water/meth will fix that.

dllhg

I appreciate the help.

Arent you trapping 125 MPH at sac ? I did trap 121 on my first pass. Wow you are trapping 102 in the 8th ? Atleast my 8th mile was the same from beginning to end which tells me the timing isnt being pulled much until the back half. I am wondering if Sac changed their 8th mile beams recently . It was reading a couple high last time I was out. Perhaps it is either correct now or a little low They seem to play musical chairs with those beams.

I am still running the canned/custom OE tune. I plan on doing a dyno session with OE but might wait until I get the new IC pump to see if it helps. I know one guy with similar mods said he picked up 60-70 WHP going from the canned tune to dyno tune . I imagine I would get a solid 30-40 anyway. I know it will make a big difference.

So you actually push the button that raises the car an inch ? I didnt remember that and I didnt even try that. Makes sense for weight transfer. I think the power braking was hurting me a bit too. I bet it was enough to shut down my chiller. I probably started with a good 30 degree higher IATs that I could have off idle. Burn out will heat it up good too. I

My biggest problem on most runs was spinning badly except for a couple runs. Some were well after the initial launch,
