Interesting, well if any heat soak is negligible, then I'm leaning towards the a2w system. @coach and @nsusammyeb how long did you run your a2w setup? How many times did you have to service or replace the pump? I like the idea of a rebuildable pump.

I don't run antifreeze on any of my systems as it isn't effective.
I have run A2W as a daily driver, and no issues. If the pump dies, just don't boost the car until you replace the pump. I run Jabsco pumps as they are high flow, rebuildable and hold up to large temperature ranges.

Brent most people don't run a large enough enough tank. I agree with 3 gallons you will be good to go. I looked at going a2w so I could have my a/c back and keep the koyo radiator. I still may do this.
Thanks. I was looking at kits from frozenboost.com and votionspeed.com The FB kits have an option for the Bosch pump where as the VS kits come with it.
