The following is the best technique for you guys and is what I used to do long before heaters and N-Boost;
1) Have the biggest or most bottles you can carry on the vehicle
2) Set the mixture to be correct at the normal ambient temps in the UK
3) Top up the bottles after every run to the same weight
4) By keeping records of pressure and required nitrous jet adjustments you can then alter the nitrous jet to account for any pressure changes you experience, so that the mixture stays constant and the race results the same.
5) Alternatively you could adjust fuel pressure as Tezz is doing and as long as the variations aren't too big you should see little difference between race results.
Trev topping up bottles is this just to make sure to maintain liquid all time or is it to avoided as i found on a bike to lessen the effect of the liquied sloshing about once ya start to empty bottle , as with bottle oriantation i never had a prob with full bottle yet a 50% full bottle i got probs till i either run a vertical dip tube or inverted bottle no dip tube, if i top up bottle this will reduce the temp of the liquided nitrous and pressuer in race time about hour between runs may be oki local track with 15 min turn around i would be at 800psi max
if i had a van would top up with nitrogen and when empty fit spares that had allready come to normal temp
as you said within reason i can ajust but there are a set of limits i have to be within to run and not just waste gas
biger bottle yes i see thats can be better , yet on bike time it takes for warmth to get into the nitrous is a lot longer than my 20oz bottles so even if its cold i have at leasta good chance with 20oz bottles of getting up to pressuer
as i ride my bike to track i now have no choice but to fit bigger bottles due to bhp im running, , new bottle will be 2.5 lbs i run twin 20oz on bike linked and to balance each other i just kind of get a feeling bigger bottle may take **** of long time to ajust but once has will stay there and more stable
