One of the local open wheel drivers has a swirl pot on his car which looks similar to this.
http://www.mellowyellow.westfield-world ... /cos16.jpgI want to install one inline right before the radiator to allow the coolant to aerate and also allow the radiator to be completely full for more efficient cooling. Currently there is a few inch gap at the top of the radiator for expansion. I feel the radiator would work much better if it was full of coolant and a swirl pot took car of the expansion.
Anyone know where I can get one fairly cheap. i think they may be called something else int he US as most of the ones I see are on UK or Australian sites and they are either custom made or crazy expensive. It seems to me this should be a $50-$100 part. Let me know if anyone has a good cheap solution. If a production car has what I need that will work as I can go to the scrap yard for one.
They are not hard to make if you have access to a Tig. Just a fat piece of aluminum tube, some end caps, a couple of weld-on nipples and a filler neck. Low cost and built to suit your car's cooling plumbing arrangement.
