i actually thought about the effect of puddling as well, but there a a couple of things as to why i dont think it will be an issue;
1. Unlike a typical air to air intercooler the air/fuel mixture will not be passed through mulitple tubes just the intake tube whick never changes diameter so the sharp angles where fuel would collect should be at a minimum
2. another factor i believe will help minimize fuel puddling is the length of the intake tube itself, it will only be 2 feet max, vs the 6 or so feet required for plumbing with a regular intercooler
3. this isnt a typical water-to-air intercooler so the basic design is not complicated at all and should cost very much to fabricate
of course its all hypothetical at this stage so who knows but those are my hypotheses based on the research ive done. once i come back from deployment ill be able to start putting all this to the test.
