its all about the math behind how cooling is calculated, but yes 10:1 would make sense or 9-1 but its not nor is 8-1 im currently testing 7-1 im going to guess its going to follow my first ratio to and be between 6 or 7 - 1

ok so from testing iv found 7-1 the ice still explodes first, then 6-1 they both explode extremely close together, but it appears the water one explodes just slightly before the ice engine does, so effectivly im going to say my orignal ratio is correct or close enough to correct but to keep it simple its 6 water to 1 ice, if anyone wants to submit that information to the wiki that be great but yes, for everyone looking its 6-1 approx

Here the real answer, Testing when they blow isn't the best technique to use as I just found a better way to do this. First I did this

Both on fuel and at the default 20C and fulled both tanks and here what I got

Both stopped as soon as the water was gone. So this test basically is saying ice is about 5x better than water. If I had to pin point the exact mb used it's would be 1800mb for every 10000 mb of worth of water cooling. So this is saying that you need about 1mb of ice for every 5mj/t so idk if you could cool a Fueled engine off of 1mb/t cause it's more tab bit more potent than 5x.

its slightly more then 5-1 as you can see in your ice screen shot at the end it isnt even down 2 buckets yet.
very good test tho, and i have done the same thing and got close to the same results at the begining of my post, but as i tested more and tryed some math some more i came to the 6.25 - 1 , then with the bringing them to exploding, confirmed this between 6-7 to 1. and exploding is quite viable because heat gain is consistant after the coolant is removed and its always fun to blow stuff up :D

So yea a combustion even on fuel don't even need a constant 1mb/t but just to be safe, you'll want to assume 1mb/t for every fueled powered Combustion engine.

im kinda to lazy today to run the numbers but, 1 aqious acc can output enough water to support 3 engines, if we figure out its water gen per tick then / 3 will give us the baseline for a single combustion on water, then we multiply that by the ratio for the accurate mb/t

Water is 1 to 1 so one mb/t will keep a lava engine cool and 6mb/t will keep a fueled engine cooled.

I think you just uncovered a bug. If the recipe GUI indicates it should only use 10% of the water consumption, it should only use 10%. Problem is the microtransactions of the combustion engine seems to be rounding up the ice Usage, hurting its efficiency. Problem is, in order to fix this, the only way would be to increase water consumption per tick to level it out. Its similar to how recyclers don't increase EU usage in proper proportions with one overclocker.

Good find, and it shows how important tests can be.

Yea but now GT makes IC2 machines off the leap so you can't "exploit" that. Oh and normal IC2 recyclers would even use less than 1 eu per operation with 2 so the breaking point was 3. Now with the 1.5+ GT now your going to lose power no matter what machines you overclock cause of the ridiculous 4x power draw.

What could you possibly need so many combustion engines for that it it is actually worth it to set up a coolent system instead of aqueous accumulators...?

Also, I can easily run 4 combustion engines off of 1 aqueous accumulator.

Yea if your going crazy like that you may as well use boilers. Yea you got it right with 1mb/t of water to spare. So for every 6 AAs you can 25 engines.

i wouldnt call it a bug, its all in the math, just because it says a coolant value of 10 vs water 1 doesnt mean its 9X times better, if there is a decrease in effective cooling.. or somthing along that lines someone would have to go and look into the coding to review how the mod dev handels cooling and how the cooling value effects befor we can class it as a bug.. but i suppose for the time being we could consider it a bug until someone looks into the code or asks the mod dev.[DOUBLEPOST=1373073171][/DOUBLEPOST]

ultimatly i dont think ever there would be a point where i wouldnt use the aqueous but its just finding more information on the crushed ice to see if ever i would be worth the hassle n it could be but most people will stick with the aqueous for how easy it is to set up

boilers for days lol and i didnt realise you could run 4 off of one i was under the impression it was a 3 to 1, shows how out of the loop my math is on some of these topics lol all good info tho.

thank you everyone for sharing if anyone else stumbles across more information be sure to add it here and or submit it to the wiki we need to get this information out there, the more its out there the more accurate it will become.
