So I'm in the process of switching from the stillen heat exchanger to the frozen boost exchanger. I thought of something in the middle of the install and I don't think I've seen anyone do it. I was thinking that it would be possible to have the stillen heat exchanger and the frozen boost exchanger feed off each other. I have enough space for both. I'd have the manifold go to the in on the stillen unit and the out go to the in on FB and the out go to the pump. Anyone ever thought of doing this? Can the pump handle it? Would I lose pressure? Yes I know air to air is the best option but that's gonna happen later.

 

I don't think there is room , Just remove the Stillen one it wont help anything. You still have the one in the manifold along with the Frozenboost one.

 

^ what ANMVQ said. When I was installing mine, I had the same thought, and then realized that the bottleneck is in the manifold. The FrozenBoost heat exchanger is already way bigger than the one in the manifold, so you're already offsetting the water temp as much as you can. The issue is that the manifold heat exchanger is just not enough to keep up with the demand. You can run ice water through it, but when you're on boost, that sliver of a heat exchanger will only do so much when you have hot air rushing through it. So in the end, yes, you'll lose some pressure, but the lost pressure won't matter. And yes, best case is you'll decrease the water going into the manifold heat exchanger by a couple degrees, but in the end, the air that the engine sees will still be pretty much the same temp. The other drawback is that you're blocking more of the radiator by running both heat exchangers - something I didn't think I could afford since I track my car (road courses).
