Okay. So I know there are he installs all over but all the zzp hose routing links are broken. I found some diagrams but it never factored in the option B it only account for the dual endpass. So my question is, can I run a secondary HE with dual endpass and opt B? I've already have the endpass and heat exchanger installed I'm just a little lost with the hose routing. If anyone could give me a working link to a diagram that would be awesome.

Search my threads I've posted. You will find a heat exchanger install thread as well as a dual pass install thread.

In both threads I mention how to install opt b. Also, if you go to crate engine depots website, they have the dual pass and opt b install instructions for you to download.

Your thread is actually the main one I used. My problem was with the hose routing and the link you posted for it doesn't exist anymore. I think I found one and I got it all together now so here's to hoping it works. Thanks for the help

Yep, pretty much the same one I found. So I got everything installed and have no leaks or check engine light. I installed the ottp stage 1 he, and the dual endpass with option B. What should I expect to see from these mods in terms of making sure everything is running correctly?

10-15 degrees above ambient cruising.
40-50 degrees above on hard pulls.
Quick recovery when high load ends.

rorywyn... remember those ^ numbers can vary a bit, so don't get upset if they aren't exact.

If you don't have trapped air in the system, the temps will recover quickly after a pull. If the temps lag, you either have trapped air, or a malfunctioning intercooler pump.

Just something to think about if you come across an issue.

That too.
Also, IC do not just die, they get weaker first. Keep that in mind as well because it could be time for a new pump if yours is tired.
Also, coolant mix plays a role as well.

Okay so I've been running my car with these mods for the last few weeks. Also installed the zzp longtube header and cat package, everything catback is stock and aem intake. I'm worried because my coolant temp rises at an alarmingly fast rate compared to wait it was before I installed these cooling mods. Cruising or after a pull I'm seeing 178-181 but if I sit at a light for even just a slight minute I'm pushing a little over 200-210. As soon as I start driving the intercooler does its job and drops it almost as fast as it rose. I'm just wondering if anyone could point me in a direction of what's going on on what to look into.

that aftermarket front mount is junk.
blocks air as well to the main radiator assembly.
oh well
usual disclaimers and general whining.

rorywyn

Not really whining just trying to make sure I did the install right. Thanks for the useless opinion though

n20saturn

your talking about engine coolant temp right? hope not IATs

rorywyn

Yessir just coolant temps

haha. useless opinions.
Fact: The engine cooling system and the aftercooling system you asked about are two seperate and distinct systems.

No direct relationship other than cooling air flow considerations and inlet air temperature post supercharger.

Block air flow to the main cooling system with a FMHE and you may get the results you are suggesting.

The FMHE are not dual pass like the OEM heat exchanger. They are chinese radiator cores of some variable value.

Good luck.
