[QUOTE="Catmonkey, post: 15791393, member: 124025"] I think the bigger problem is the size of the tubes in the intake manifold that connect the intercooler to the manifold adapter for the coolant hoses. It's necked down to .55". Hose diameters in the stock system are .75" and most of the barbs and tubes in the remainder of the system are ~.63". The intercooler tube has got to restrict the flow of coolant to a large degree. Someone makes a larger tube and adapter, but you have to plumb it with AN fittings. I ended up opening the cooling tubes to .63" with a grinding tool and a master cylinder sized bore honing brush. I also opened up every hose barb in the system to .65". Just by area alone, that is a 30% increase. It would also seem to me at some point too large a coolant opening and the intercooler becomes the restriction. The Bigun is a bigger benefit coming from the 07-12 intecooler and that benefit is really about airflow. I've not seen any evidence it provides better cooling. The 13-14 got an upgraded intercooler so the airflow benefit is not that great and to get optimal airflow, it does require some porting of the manifold opening at the intercooler. I think your money would be better spent on getting the coolant to flow faster because the real benefit of the Bigun is more about moving more air through the engine, not cooling down the air charge. Lingenfelter also markets a BW intercooler pump that is the mac daddy of pumps. It is not impacted by flow restrictions as much as the stock pump and many other pumps. [/QUOTE]
