Thread: IC Condensation
10-28-2009, 10:49 PM #1
Has anyone had problems with condensation in the IC after doing the dual feed mod? When I did mine at 40 hrs the IC was clean and actually looked new inside. After I ran it hard the first day out on the lake, I pulled the I.C out and dumped about 1/2 cup of water out of the air section. Also noticed some sludge in there that very slowly poured out. I've cleaned the IC and going to put it back to stock to see if that fixes it the problem. Maybe to much cool water for that hot air getting rammed. I remember seeing another post that talked about it, but can't find it. Just wondering if anyone else is experiencing this?

Condensation in IC is very unlikely IMO when considering temp drop in intake air between before and after IC is only about 20 to 25F. And still the exiting air temp is higher than that of ambient air. Also, the condensation theory still doesn't explain the "sludge" which is mixture of water and oil. I suspect following:
> Cooling water leak inside IC.
> Water ingestion (very little) into air intake.
> Oil getting into air intake via crankcase breather route.
Above are all likely to occur especially in hard riding.

yes all are possible. maybe he had some grit build up and condensation added and poof, sludge! but too cool a water can give condensation, the R&D kit has or had reducer fittings available when it first came out. that may be the reason? but i have the same problem and my i/c is checked often for pressure. still and resolve it. I figure for me the first step will be to lower the in compartment temperatures and intake temp, then figure out if the water is in the i/c for too long or nt long enough, that type of stuff, ah fun iguess

I cleaned the IC and converted it back to stock, I will run it hard when I get my pump back from Impros. I will post my results. Thanks for the input

going through this at the moment i ride hard and in salt water yet the water i have just drained from my intercooler is fresh water. i have pressure tested and no leaks so most definatly condensation only extra mod. i done was i drilled out feed fitting from the pump. so i will return the fitting to the standard one and check again. how many others are having this issue? i have ran about 4 tanks of fuel through since my rebuild and drained about 1/2 cup of water out of the intercooler and around 1 1/2 cups out of the catchcan which is a mixture of oil and white milky oil/water.

Whats kind of wierd is that when I did the IC mod at 40 hrs the IC looked brand new inside with no oil or water residue. I did the IC dual feed mod and put the valve cover block offs on and poof oil and water in the IC. I wonder if the valve cover block offs had something to do with this, like I said, I did both mods at the same time
any input would be appreciated

i wonder if adding a small pre-cooler (intercooler before s/c) would help?

just treat it as water injection it will help with cooling i am
