ok got a question for those who have installed the duel pass . is it possible to install it without removing the intake manifold thanks for any info.

 

needs to be removed

 

yes the manifold has to be removed. i believe you can get the end plate off, however you need to pull 2 of the cores out and flip them around so you have the correct flow through them.

pulling the manifold is pretty easy. once the blower is off, unbolt the alternator and that allows you to get to the 15mm bolt going into the support bracket. once thats undone, unhook the coolant lines, unbolt the dipstick tube, remove the 5 bolts and 7 nuts holding the intake on and pull it off.

 

I though pulling the intake was a bitch. I didn't take off the alt though, i took off the H/E pump and suffered removing support bolt 1/16 a turn at a time.

 

i just did it, twice. i had the intercooler pump off but i still saw no easy way to get it. the alternator comes off real easy and you can get on that hidden manifold support bolt with a ratchet and deep socket with ease.

 

Thanks for the info guys should have known better than to think anything on this car to be easy lol

 

its not all that hard just take off the supercharger than the 5 bolts from the intake mani im pretty sure and its right there u cant miss it more or less

 

Does this even give you any more hp?

 

OMIGOD use the search button. Cooling mods help you keep what you got. If you make more power you make more the heat and the heat sucks the power all away...car slows down.stops. yikes. search. grrrr.

 

Hey ******* it was a simple yes or no question.

 

Man all the hostility lol

 

All I asked was a simple yes no question. I'm not that common with the LSJ's and plan on buying one so I figured I could ask here since it's already started about it, but I guess questions aren't aloud anymore. This site is pointless and there are to many children on here.

 

No, welcome to the internet. You're going to be told to search on any car-related site.

 

Dont let a few ppl discourage you mp. There alot of usefull people on here that give good info just take the good with the bad.

 

Yeah, people get angry when a question was answered and discussed over and over and over - even if it is in a hidden thread somewhere buried in page 4 of a search, lol.

But, the best thing for this site is to go to the related forum, click the "Search this Forum" link on the far right, and have at er. There you will usually find your topic of discussion has been discussed in many threads.

Best of luck on the mods. Here are a few great threads/info to get you going on duAl pass / cooling info:

Very good way to explain things, and help em along too..

We need more of this.

 

Oh I forgot to mention I plan on doing this from the 13th to the 15th of March. If you are bored......

 

I'm gonna be busy during the eve of those days but should be able to help during the days, Swing me a text when your gonna do it.

 

Sounds good - thanks. I might give you a call if nothing else if i get stuck haha

 

If you don't switch the laminovas what will the motor do? . I ask this because I have had this done for a 1.5 years and had no problems yet. I have just downloaded the latest instruction for CED and it has changed since I got the endplate and installed .It actually has the hoses on the directions now and diagrams of the 2 "hidden" bolts under the manifold. I did not switch the laminovas to the center and make sure the small orifice is facing outwards. I left it the way it was installed in the manifold. Will this cause the endplate to not work right?

 

Basically...

The dual pass changes the way the coolant flows as well, so the laminovas have to be changed..

there is a good chance you putting Hot coolant into the engine... instead of the cooled stuff...

 

Explaing this further I am not quite understanding... The water is going to be cool no matter which way you have the laminova's placed or which way the water is entering or exiting.. The performance might be a little different. I thought I have heard of people intalling them both ways. Maybe I am just not reading your answer correctly, i am a little hung over and will probably laugh at my post later.

 

When you did yours did you pull the tubes out and what did you use to pull the tubes out with and did you place the small orifices to the center?

 

Yes I pulled and moved them to the middle two spots.

 

Just to clear things up.

1) The motor won't do anything and there is no coolant from this system in the engine. It is completely separate from the engine cooling system.

2) If you add the dual pass endplate and don't pull the laminova cores, you are creating a situation where the coolant flows WORSE than stock. Stock is something like this:
Flow of Laminovas:

1/<<<<<<<<<<<(stock endplate nozzle)
2\>>>>>>>>>>>\(redirected in endplate)
3/<<<<<<<<<<</
4\>>>>>>>>>>>(stock endplate nozzle)

If you add the dual pass endplate nozzle, keeping stock laminova locations:

1/<<<<<<<<<<<(stock endplate nozzle)>>>>>>>to surge tank and / or pump
2\>>>>>>>>>>>\
------------------------->(open due to new nozzle)<<<<<coolant being pumped in<<<<
3/<<<<<<<<<<</
4\>>>>>>>>>>>(stock endplate nozzle)>>>>>>>to surge tank and / or pump

What happens here is the 2nd laminova resists backflow and will push the coolant over to laminovas #1 and #3. #3 will take the coolant and push it through to #4 as well. #1 will fill up, but due to a closed loop between #1 and #2, the flow will stop or slow down tremendously, possibly pushing hot coolant back into the surge tank / pump as it is the path of least resistance. Basically , it's a bad idea. You are now extracting heat at somewhere between 40-50% less than stock.

The way it is meant to work:
1/>>>>>>>>>>>(stock endplate nozzle)>>>>>>>to surge tank and / or pump
2\<<<<<<<<<<<\
------------------------->(open due to new nozzle)<<<<<<<<coolant from H/E<<<<
3/<<<<<<<<<<</
4\>>>>>>>>>>>(stock endplate nozzle)>>>>>>>to surge tank and / or pump
