I wish! Winter started here already. Freezing for the past 1.5wks and snow on the ground. Will trailer to the dyno in the next couple weeks but that’s about it until April now.
Its hard to say since you added more places that need to be cooled. A stock car takes about 3.5 gallons, id say you are close. You will need to drive the car a bit to get the rest of the air trapped inside.
Same here. Got a big dump of snow on Tuesday, but the roads were dry today with +1c / -2097 DA / 35% humidity, that's like 45 extra horsepower haha.
Haha, ya this is beyond boost weather.

Ford recommends vacuum filling, but I don't see an issue doing it the old-fashioned way. However, it'll take more than 'a couple of rounds' to fully purge the system. Some engines have a purge bolt somewhere on the engine, to avoid air-pockets/cavitation. Maybe this one doesn't, due to the vacuum recommendation, meaning any air should eventually be purged out.
Just fill it normally and burp the system with the heater on max.
