I’m relatively new to wrenching on my 2004 996TT X50 and decided to take on a major project this spring that will include new plugs, coils, oil change, fuel filter, AP boost hoses, and 997.2 intercoolers. I’ve received great advice on this forum in the past.
I’ve been attempting to follow instructions on this site for modification of the factory air shrouds to accommodate the larger IC’s and had some questions about how to properly seal the IC with the shroud. I plan on connecting the boost hoses to the IC and running an individual pressure test on each side before final assembly.
There appears to be a small gap on where the upper shroud meets the 997.2 IC that I have circled in the pic. The gap still exists even with weatherstripping applied. Is this something that I can simply seal up with RTV? Based on other threads, I’m assuming that each IC should be able to hold at least 20 psi?
The area you have circled will have no effect on boost leak. I think I am looking at something you put inside the the shrouding(that is blocking some of the core from getting air flow)?? You may need to trim the shroud to fit flush. Then you can add a silicone sealer (use something rated for the temps).
