Hi

I'm in the process of designing an intercooler for my car, and need some info. By the way, this isn't for a Cobalt . My car is supecharged and is made by GM, lets see who gets it right first.

Need Gm Part #'s for

Laminova o-ring
Laminova Washer

Here's a picture of the diagram







Also can someone explain to me how the water flows through these tubes. I already understand the whole concept of a seperate system and all that good stuff. What confuses me is the water flows through one of the elbows (inlet). The water then enters the outer ring grooves of the laminova core, since their is a restrictor on the inlet side. Now where I'm confused is how the water gets back to the outlet side when the outlet line is located on the same side as the inlet.

So I'm trying to say is how does the water go through all 4 cores and exit the water return line without mixing into the cooler water entering the cores. Anyone that can explain this to me, I would be greatly appreciated.

Boosted SS looks like you got it first. I didn't even realize when I posted the picture that I had my file open.

Anyone know part #'s

The ccores are each seperated on the end cap. The 2 ends have basicalley there own chamber while the centers are joined to get flaw back accross.

1. l-------- inlet
2. l-------l coolant flows into 3rd core this end
3. l-------l
4. l-------- oulet

Hope that makes sense with a carppy drawing but thats basically how it works.

well im building a 2 pass intercooler system but my system will be a stand alone with pump and a modifid catch can and the intake supercharger it will no longer work in 200 degree area it should be at air temp and a little warmer what do ya think abot this

if i have this right the SS is in junction with the heater and the rest of the coolent system as the service manual shows so if i run the system by its self it will do a better job cooling the air and will be runing at air temp is this right

i dont own a ss but i own a ls and a lt coupe the ls is geting the 2.0 supercharge but the gm build book is helpful with a service manual but it real hard aplying in my appication

btw the bottom is the inlet and the top is the exit

Thats it, thats exactly what made me confused. Its funny now that it makes perfect sense. The end caps are machined so the coolant goes from tube 1 and then bends 90 degrees into tube 2 and so on until it hits the exit.

Does anyone have any great pictures of the cores and how they attach inside your intercooler. As I know the specs needed for the tooling of the intercooler from laminova site. However I would like to see an actual setup.

So pictures would be much appreciated if anyone has any.

JJ91284, did you ever get any more info on this?

I just got my hands on a set of 4 laminova tubes... only $11 once I finish the L67 swap into the Cavalier, I'll be working on the same project as you are

Here is MOST of what you need to know about the dual pass mod

I'd read that thread already, neat info to know... I'm going to have to have a complete intercooler "box" fabricated to hold the four tubes.. then fab up some end caps w/ o-rings and so on in it...

Shouldn't be too hard... but I'm worried about clearance and sizing the whole thing to fit under the hood. I don't have much room there, as my L67 isn't in a Grand Prix... it's been shoe-horned into a Cavalier
