OK, I finally broke down and bought a King Kooker turkey fryer so I can
do full volume boils, it came with a 30 qt pot. If I want to end up
with 5 US gallons after a 60 minute boil how much wort should I start
with?

The evaporation rate will vary with the size and shape of the pot and
how much you turn the gas up for your boil. That said, I used to use
the same setup. My evaporation rate generally ran about 1 gallon per
hour. If you are using a lot of hops in your boil (e.g., an IPA) you
will want to increase that by another 1/2 gallon to make up for
absorption by the hops. Just make sure you measure your starting volume
carefully and write it down so you can make accurate adjustments for
your next brew. Congrats on moving to a full boil, you will notice a
big difference. You will now need a wort chiller if you haven't already
gotten one. Five gallons takes way too long to cool down if you don't
have one.

Who knows? You'll have to determine it for your own system. Maybe
start with 6.5 gal. and see how it goes.

Probably 6 gallons.

Thanks, that's about what I thought but going from an electric stove
wasn't sure. Can't wait to try my first full boil.

I also have a king cooker with an 8 gallon alum pot. I started with 6
gallons of water after the mash, but then after adding extract it came
to about 6.5 gallons of water (doing IPA, by the way). I did a
relatively rigerous boil and ended up with right at 5.5 gallons of
wort. In transferring to primary I only took 5.0 gallons (left a
bunch of trub in bottom of boil pot - I hope this doesn't hurt
bitterness of end product, but had OG of 1064 and target of 1062).
So, long story short - I too lost 1 gallon from 60 m boil. Cheers!

I have been successful with 6.5 gallons with the turkey fryer that has a
55,000 BTU burner and a 10 psi regulator at 2000 ft above sea level. You
have to watch the first hop addition very closely to avoid a nasty boilover
since 6.5 gallons has the volume up to the handle rivets with a 30 qt pot.

There are a lot of variables involved. IMO, try 6.5 gallons the first
time and then see how it goes. You'll learn after a little bit of trial
and error exactly how much you need to start with. It's going to be
a little different for everybody.

I hadn't considered the advantage of leaving more trub behind. When you
do a 2 1/2 gal boil it's hard to leave 1/2 gal behind, expecially when
you do two boils to get to 5 gal. As my ex would say "a charming
bonus". As much as I'm looking foward to doing AG in the fall guess I
need to get to know the tools I already have first. No one told me
brewing beer was going to be educational. Physics, biology, math,
chemistry, art and even philosophy... what a deal!
