Re: CP30 Pump = Leaking IC

My question is, does this happen only with the stock Heat Exchanger (the picture on the very bottom) because the stock HE can't handle the increased flow of the Johnson pump, so it puts pressure on the Intercooler? It seems this has happened with some of the people using the Johnson pump and the LET Heat Exchanger (the top HE pictured in the 2nd picture) as well. I wonder if this might be solved using the Needswings Supercooler?
I'm thinking of taking off the Johnson pump, and going back to stock because I don't want to replace the Intercooler, which I think is a $1000 part.
I was also wanting to know how you can tell if your Intercooler (the top picture) is leaking and needs replaced?
I hope this makes sense.
I've been running my setup for nearly a year - but I separated the two cooling systems (this should take some pressure off the IC system) plus I installed the LET HE at that time.
I would think that if your intercooler was leaking - the signs would be obvious has the engine would begin to ingest coolant.
On the other hand - if the leak is real small - it could work as an water/meth injector and drop your IAT's..
All kidding aside, when I had my unit apart it looked pretty stout.
One key is to keep the IC coolant clean, use distilled water and a minimum 1/4 ratio of MB antifreeze. It has special softeners to prevent scoring on the internal parts of the coolant systems.
