for some reason when i got my single pass manifold from ZZP the cores werent with it. they later sent me the cores but im not exactly sure the correct order to put them in. im assuming it should go OoOo from top to bottom but im not sure. i would call them but they are a pain to deal with over the phone unless you are talking to the right person. thanks in advance css

 

I'm pretty sure it would go oooo. Because o is in and O is out. Like a oOoO is stock, dual pass is OooO so i would assume single pass would be oooo because it's exiting out the other side, not coming back towards the end plate

 

i always thought o was out and O was in. i totally spaced off calling ZZP today. maybe ill do it tomorrow...

 

Definalty not. o is in and O is out. Just installed my ZZP dual pass on the weekend

 

i just got off the phone with zzp and they said its OOOO not oooo

 

OOOO towards the end plate?

 

Yes OOOO towards the endplate according to turbo tim @ zzp

 

I thought it would have been one way or the other haha. But good to know

 

He is right because the coolant enters the left side of the IM and exits on the endplate side.

 

Ohhhhh thats why. Did not know that it went through the left side first. So i was right but coolant entering the wrong side haha.

 

says who? and why? i dont think thats correct. if this is true whats to say the top cores are getting coolant... if it enters on the endplate side it has gravity in its favor...

 

It would have to enter on the left side if all the cores are OOOO because O is exit, not enter

 

take a look at the ZZP single pass manifold and see if you agree with what was just said... i cant see that being correct... you would be overworking the ic pump and you would be forcing coolant through the cores. which means slower GPM or whatever its measured in. the idea of a singlepass is coolant volume and velocity. if it flows from bottom to top you have gravity on your side aswell...

 

I highly doubt zzp is wrong....this was built for turbo tims car btw, and I spoke to him personally

 

Did you look at you're stock cores and hoses before it came apart? Stock is oOoO. It enters in o and exits O. Dual pass is OooO. The 3rd fitting they add is in the middle of the plate where it enters oo and exits the outer O's.

 

Yes it enters through passenger side and exits through drivers side, when you pull off the end plate the big side of the lamova should be there for the out

 

I was trying to find you're post of you're 200 IAT's because i know you had pics on there. But there ya go

 

I have discussed with the crew so everyone is on the same page. The system is supposed to come assembled. My apologies.

 

thanks zoom.

explain to me why... it makes no sense to try to force coolant UP through the manifold cores...

 

Actually thats exactly why. If you have it enter through the drivers side which is higher than the exit, the top 2 cores will never fill up or be used, you want all 4 to be used which is why it has to go through all of them before it can exit.

 

Idk... It just seems like you would be overworking the ic pump is all

 

That is how it is setup from the factory?

 

I'm putting mine back together and began questioning this. Small opening cannot be an inlet if my manifold was correct when it came apart.


I've always had mine top to bottom:

o
O
o
O


....coolant flows in through the bottom fitting up towards the filler neck...

 

Sub'd

 

Small opening is the restrictor on the outlet of the core.
