hey guys i'm up to the final stretch on my dual pass mod. Now i've heard that the way gm tells you to plumb the hoses is wrong and that there is a different way? i have the pic in front of me and was wondering can someone tell me what hose goes where?

 

anybody know anything? is the way the gm istruction right? i hear you guys saying you plumbed it a different way want to know what way that is.

there are 2 ways of doing it.....Blown-4-banger's way and SS33's/GM's way. I would personally go with GM. But which ever way you go Make sure you do EVERY STEP!!

 

^Sweet I have a way, muhahaha +REP for M88ArRamadi that

feel free to ask questions though man,

 

i am doing GM's way, cold line into middle and then the 2 hot lines out the top and bottom and then to the aftercooler

 

Here's how I ran mine,

 

that is how im running mine, but my fitting is different, i have a T fitting not a y, did you install that part already?

 

Yeah, been running it for about 2 summer months now,
they are the ones crateenginedepot.com sells


I have the same Y for split off to the surge tank as well
either way works, I went with the Y's, because they save space, and flow a little better. T fittings produce turbulent flow, as the fluids intersect at right angles

 

installing my endplate tomorrow. If you have HPTuners you can turn on the IC pump with it with out the motor running to bleed air out. Fun. cant wait (Sarcasm)

I am looking forward to the seeing results and impact it will have on me having the need for an HE with 2.6". Anybody with experience want to tell me how it will turnout?

 

wet...

 

Well I used a tee on mine and I haven't had any problems. My temps stay the same as everyone elses. Just use the GM recommendations and it will work out without having to cut hardly anything. I think we had to cut just one hose a little to make a little room. Good luck with it.

I also highly recommend running a mixture of redline water wetter and water. About 50/50 should do the trick, depending on your climate you may want to mix it with a little coolant instead of water.

Hope this helps.
