In the Merk I used a Coleman ice chest (about 18 X 30 X 24 inches.  We
loaded 4 1/2 bags (5 #) and added water to make a nice thermo mass.  While
in line we added the last half bag.  At the power levels I was running there
was usually "some" ice left.  A few times there was none, but the water was
still Very cold. (actual temp not known)
Consider though that I was compound cooling using air/air with water spray,
then air ice water.  I cant do that with the lakester, but will try to add
capacity with a second tank up front.  Packaging things in this little tiny
car is way harder than I thought it would be.  We think  Boy there is sooooo
much room...yeah right.  I'm sure you have the same problem....well, just
make the car longer     :=d
Another bit of info.
Banks when he ran the Firebird used ice water.  The first year a fairly
small tank.  He had some valve seat issues and the next year came back with
a huge water tank, and of course huge success.  I'm guessing that he was
running out of BTU's and experiencing detonation at the high end.  Nobody
knows for sure though.
I have stayed away from dry ice because of the difficulty with any fluid at
that cold a temperature.  Most fluids become too viscous and hard to pump.
Since we all need extra weight, in the right places, water does a nice job.
