Dualpass Option B?

optiion b is a new remote reservoir eliminating the dinky t bottle useless OEM sight glass reservoir. the new reservoir is a redline coolant bottle put in the car left hand opposite to stock coolant bottle with a plumbing addition of a bleed line the system becomes self bleeding with more coolant capacity and a higher pressure cap that does not fall off like the OEM one! the dual pass refers to a new end plate for the laminova which has an additional port, and requires you to flip the laminova cores, and re plumb the system. both are really worthwhile mods to keep what power you have on a repeatable basis.

Too bad you can't put the option b on without the dual pass. From what others have said.

you can, i did, why not? it just replaces the slly OEM t bottle and adds a bleed line to the top of the h/e the original plan proposed was to put it into OEM production that was quickly shot down due to cost...just like the mis wired pumps was a tsb not a recall as there were no lives at risk....

Can you seriously take pics? Everyone I've heard from tells me that you need it with the dual pass for it to work. How long have you had it hooked up for?

Same here, when I put in my cobra I also installed my secondary tank. I left the stock fill neck in place so I can easily make sure the pump still works.

So where did you guys plumb in the line for the tank. I know the one side goes to the bleed screw on the side of the HE, but what about the other line?

[Watts-Up]

I put an extra cobra reservoir in mine. I just ran the hose to the stock filler neck, and to the cobra h/e. I'm sure there may be a better way, but it works, and it does a good job burping all the air out of the system.
