Bruce you need to replicate my setup so you can offer it for sale to other members.

Here are some pics

Tony stagger both the heat exchangers together and you will be happy. Dont worry about the rear one getting hot air etc etc.

I was thinking the same, running the two would increase vol for sure but i question the end result vs swapping a larger unit w/ pump. I got one of the larger ZZP units that i plan to run alone but Im always looking for more info.

tbal

If you and Bruce say so, then I will. Thanks Shardul

Fingers crossed the e63 bumper doesn't *** with the HE...

What about the oil cooler, does it need to be moved?

shardul

it will fit the e63 bumper. since you are not messing with the stock unit the oil cooler will remain in the same location.

i dont think the Bosch can handle 2 HEs -- you are better off using 2 pumps to push and pull --- I got an 06 pump sitting if your interesting.

tbal

The pump I have in the car atm still works, just for maintenance sake I am replacing with the bosch...

So should I run both Pumps? I rather keep it on the simpler side to tell you the truth. So Having 2 HEs and using the bosch pump not a good idea?

Now Im really confused lol

Bruce, Shardul...... lol

Anyone

use a one meziere wp136

Already bought a Bosch. Bosch won't work? Looks like I'll just do the single he than?

This going to sound like I'm being a dick but this a repeat of a prior post I made. You need to get logging equipment first. There is no ONE magic answear when it comes to modding. Log your temps stock, and make small changes and see what works for you and your car. You can never know if what your doing is working untill you know what you have. If it was me I would:
Log my car stock

Change pump (that you already have)

Log again

Seperate the engine coolant from SC coolant
Log again

Add Second HE

Log again

Add stock pump to bosch pump

Log again

Add Trunk water tank

Log again

Add large meziere

Log again

Add water/ meth injection

Log again

Add Killer chiller

Log again.

To me this is the most logical approach to DIY modding. At some point you will feel that you have meet your cooling goals.

tbal

True that would make sense, and would probably be the best bet, but I figured from people's past experience they would know which setup works the best...

sneakyneon

Most people just make one change and live with the results, They buy a vendors kit and call it a day. If you want whats best you have to exspirment.
My cooling is:
6 gal trunk tank
1250 gal/hr pump
monstor size Frozzen boost HE
Dual Nozzel Water meth injection
My IAT never go over 90 degrees with 195mm pulley@ 19psi

I'm still not happy and gooing to keep working on it. Next I'm going to try
3 gal tank
larger feed/return lines
DIY killer chiller

Your too crazy lol. I would love to try many setups bit really becomes a time issue for me.

If you were to do this once. What would it be?

Single he or should I run both stock and zzp he? Split ic? And more importantly would the Bosch be enough to push/pull the coolant through 2 HE's?

i haver the smaller version of this engine and would like to add a comment or 2 . separating the i/c system from the engine is a huge gain. going from a high pressure setup to a low pressure setup greatly reduced my iat's. then use as large as possible h/e for your car. the more surface area the better for cooling . i use a cm30 pump but only because it was a longer lasting unit not a better flowing unit. my iats run consistently 100* lower than engine temps until i run wot. then i peak at about 120* running 65* cooler than the engine.

the remote tank will allow longer time at cooler temps but eventually all the fluid will run at the same temp unless ice or long cool downs are inserted into the equation.
as sneakyneon said testing and logging are the only way to know what works best for your application

ahmad0658

Would please give some details about your meth kit? what kind? stage? how well it stand? mixture? where the nozzles should go? Anything could help.

Thanx in advanced for your time in writing

tbal

Thanks for the input! Splitting the system makes that much of a difference?

My original question I am still a bit confused on...
Single he or should I run both stock and zzp he? And more importantly would the Bosch be enough to push/pull the coolant through 2 HE's?

Already

Give it a shot and log the results... Only one way to find out! I dont think anyone can questions that the best way to add volume to the system is a remote(not underhood) tank but second to that it's got to be an additional HE, the problem is placement; will it be benificial to squeeze another HE between two other hot things looking for cool air to flow over/thru them so that they are able to perform? where are we moving the oil cooler and is it able to cool adequately? how well if at all is the second HE cooling after getting blasted with warm air from the first larger HE? Does the additional friction loss in pressure effect anything? those are the questions you can answer by logging the data.. then I can ask you and copy your setup

sneakyneon

Its a devils own universal stage one with a boost activated switch set at 12 pounds. First nozzel is # 3 right before the TB the second is a #7 pre IC. I run 80% percent meth. Kit is ivery simple and effective, there switches are complete Poop. I switch to a Hobbs pressure switch.

sneakyneon

Here is what you do, Split the system and put in your new pump in. With a 165 pulley this should be a big help. Huge differance in heat when going up to a 180

tbal

Since the new HE on its way, I thinking Im just going to split, run new pump, and just the new HE.

Too many darn setups!

Thanks!


(Looked at the splitting ic diy... seems kind of confusing, any pointers?)

does your new h/e have a cap? if not splitting the i/c you wont be able to fill the system unless you run a overflow tank. if you look at your reservoir there is a large line coming out under the tank and a small line from the i/c to the tank. simply cap the lines off and the system is separate. my h/e is built from a radiator so it has a fill cap. i haven't ever had to add any fluid once the system is bled

tbal

I get it thanks! Hence why people add the BMW power steering res. as a fill point?

320 dreamer

that is correct. and they use a large tank in the trunk for adding more volume and the ability to drain and add ice for faster cooldowns and longer time at wot
