I have a hard time understanding what this plate does...do you need to buy anythign else? if you buy it form gm is it all you need?

 

i Agree. can anyone elaborate for us. or maybe some pics of the before and after setup

 

Click on the link in my sig that says "Dual Pass IC Mod"
That should clear some stuff up for ya

 

I just got Mine in the mail, My New Dual pass Heat exchanger got here yesterday! Now waiting on my Custom made Billet Overflow Bottle <<From BWoody! I should be seeing some very cool Numbers & For down here in Florida its always Hot! It should Help alot! Im logging all the #'s Now with HP Tuners & going to Log the #'s after!

 

If I might make a suggestion.

Get a logs of simulated 1/4 mile runs if you have a safe place to do it. Something like 5-95 MPH at full throttle would be usefull information. Don't forget to bleed the air out of the stock HE so it's a fair comparison.

It would also be usefull to do the endplate mod, get data then ad the aftermarket HE so as to be able to evaluate each change independantly.

Good luck

 

Already Logged all the above, The Problem with doing each 1! It will envolve To much time! I'm Doing the End plate & exspansion Bottle at the same time Because of Plumbing change. (Option B) of Endplate Install!

 

not expansion bottle but, Heat Exchanger such as the cobra one or the cobalt addiction HE
i just got the GM endplate, the GM surge tank, cap, and y fitting, intake gasket(updated for more boost)
THanks CED!

also i plan on running dual pass option B, with an additional cobra heat exchanger, with the stock HE as well

waiting for more parts before i install

 

I consider the expansion tank to be a required addition. It would be very hard to get the air out with option 1.

What do you have data logs of so far?

With the expansion tank (the one from the redline) you just run the over flow hose to the fitting on top of the stock heat exchnger correct?

The 1/4 inch Outlet is the Bleeder Line, For the Bleeder Valve you have to install!

 

Not the overflow hose. There is a small fitting near the top, 1/4" hose I believe, that gets plumbed to the fitting on top of the exchanger using the .040" orfice.

^^^Yea there is a 1/4 Plug in the Stocker!

 

if your going with the GM one theres two options A and B, B requires an additional surge tank y fitting and cross lines

 

Correct me if im wrong. Maybe im missunder standing. But on the extra coolant bottle. Theres a 1/4 inch hose running off. Gm says make some goofy bleeder set up. Cant you just take that 1/4 line and run it to the top of the heat exchanger where there is a fitting there that gm just put a plug in? its the highest point in the heat exchanger and the highest point in the coolant bottle. That should mean it bleeds all the air out?

 

I just finished doing option B last weekend. You are correct, the 1/4 air bleed line goes from the top of stock heat exchanger on the passenger side where the pipe plug is, over to the top of the stock Redline coolant tank's 1/4 nipple. HAHA, I said nipple. The reason the .040" orfice is there is to restrict flow back through the 1/4" line.

 

haha, you said orifice....

 

are you supposed to bleed air from the stock exchanger as a regular maintenance or is there a stock coolant for it that you have fill? im lost when it comes to heat exchanger thing? what im trying ask, is there any kind od regular maintenance that needs to be done concerning the stock heat exchanger at all?

 

No normal maintenance required, the bleed line automaticly bleeds air out of it. You may just have to top up the coolant resivoir time to time at first.

 

I just had to top up. Stage 2 install makes the coolant level drop a little. No big deal.

 

OK so we flip the bottom two laminova tubes around and feed the coolant from the pump into the centre and the oulets top and bottom get teed?? just getting the fitting welded on and going to do this mod when I get it back. This is what it looks like to me but I don't have the instructions.

 

question is this mod worth it or a second HE is enough i want to get both but don want to spend money if i dont have to.
