Hello all again. I am helping a friend install an xp cam etc. into his L67. We are also adding a zzp short stack intercooler. I am on unfamiliar ground here but when I look at the intercooler, the case separates into 2 halves with the small heater core like thingy sandwiched in between. There is a shallow groove milled into one of the inside surfaces that looks like it is to accommodate a rubber seal or is it possible that this groove is simply filled with RTV or some kind of sealant when final assembly of the intake takes place? Thanks as always

Is there a question here?

Yup. The question I guess is this.
1.) Is there a rubber seal of some sort that goes in the groove?
2.) Does this groove get filled with RTV or some other sealant?
Orrrrrrrrrr
3.) Is there no type of seal in there at all?

I'm pretty sure we can dismiss #3 and I'm leaning toward #2. Just hoping someone can confirm this.

I'm having trouble picturing what you're talking about, but I can't see why you'd need anything there. The heat exchanger wants metal to metal contact between the cores, anything insulating like silicone or rubber would reduce heat transfer. Did you try calling or emailing ZZP?

The ZZP SSIC is essentially two aluminum plates that sandwich a small heater core and the 3/8" feed and return hoses in place. Put those hoses on the fittings and carefully assemble the plates so that you do not pinch anything. A very light layer of silicone sealant is used. I don't know why you are asking this question as all of the SSIC's that I have seen are purchased assembled and don't arrive in pieces?
When installing use the longer supercharger bolts provided, a gasket above, below and use a small bead of sealant on all surfaces of the SSIC. Don't forget the coolant passage O rings on the series II engines. Torque in small increments in the proper sequence and spin the supercharger pulley by hand after every torque sequence to make sure that there is no binding. If there is binding, try backing off the bolts near the snout end just a tiny bit until it spins free.

I guess I should have mentioned that this ssic is used and is in 3 pieces.
