I was wondering how to run the hoses for the dual pass option b. I have a second h/e. I have checked rlf and here and they way I have seen it run can not be right with a h/e. So if somone could post up a diagram that would be great.

 

 

i hate diagrams like that =[

 

Thats an awesome diagram, i would remove the stock heat exchanger tho. It sits against the stock radiator and takes in heat from that. I saw lower IAT2s with just an aftermarket heat exchanger than with both.

 

ok how you run the lines with option b then also?

 

If you install the extra HE it looks like it goes in front of the AC Condenser. That being said, does the heat from it affect your AC? Does it effect your engine cooling as well? Can you do it with stock pass in the intake manifold?

 

you wouldn't happen to have the diagram doing this plus with option B?

 

This is what I used after bleeding everythig it works perfect.

 

That's exactly how it should look.

 

I need to re route some lines then

 

Yeah I had to do the same thing. My h/e was hooked up then when I installed dual pass I had to reroute everything.

 

Well, some of them i've seen have it coming from the second H/E out to the I/C pump then up to the middle inlet on the dual-pass plate. Same fucntion, uses more stock hoses. That's really the only difference.

 

sub'd

 

cool thanks for the help. this will help when I get the car back together

 

sub'd. adding a front mount heat exchanger this week with my option b.

 

i would have removed the stock he, as someone mentioned u get lower IATs without it

 

Sub'd, i was looking for this last week! Installing meth, dual pass, H/E and option B all at once very shortly. Does anyone have actual proof of running lower IAT2's with removing the stock heat exchanger and just using an aftermarket one? In theory it doesnt make sense

 

thanks for showing me this link, it helps out alot. now i got a few questions. on the pic where it has the t then it goes up and to the left for the option b tank and also to the right, im guessinf you would need another t right? another question is whats the best way to bleed out the system. and my 3rd is how much better is the option b compared to the stu mod? i had my own stu mod on the car at one time but had to take it off cause it cracked and starting leaking so i was refilling it everyother day. this is the reason i wanna go ahead and just get the option b, but only if its better then the stu mod. when i was running the stu mod with the aftrmarket intercooler my iat2's where 120 to 130 after a quarter mile run. now with out it they are around 150. keep in mind that this is during the summer in georgia weather so for here those are good numbers lol

 

Yes you will need another t fitting. The option b is what bleeds you're system. I've never heard of the stu mod?

 

its basically running your lines through an extra resivor so it cools down faster before goin back into your manifold

 

Sounds kinda like an option b but how well does it work for bleeding?

 

it is an option b with a 2 3/4in fitting for better flow and you can pot ice in the tank wail at the track it really help to keep temps down

 

actually i dont think there is a problem with bleeding it with the stu mod, correct? i think that is y u drill a small breather hole in the tope of it

 

you don't need to drill a hole it will bleed find the tanks that are used don't have presser rated caps

 

i didnt know that, my problem is finding something to connect the hose to the resivoir so it dont leak, everything i try leaks, i searched everywhere for adapters that are self sealing but cant find them. and the top is too small to stick a female adapter in to tighten to the mall adapter to get a good seal
