Thanks! There's a decent bit of information jumbled around up there.... somewhere.... lol.

I have one on oil cooling as well, not sure if that would be beneficial to the forum as well or not though.

Thanks,
Eric

I bet it would.

I'd wrap that into a non-conventional style of cooling the charge air. You are now adding complexity, a decent bit of cost, weight (those bottles aren't light) and something that you'll always have to refill. Great idea for drag racing, much less of a great idea for daily and track cars in my opinion.

I'll work on putting it into a forum friendly format in the next week or two.

I appreciate your opinion. Weight of a bottle filled is 12lbs so with components, I wouldn't think this was too much weight seeing how it's non rotational. Also I believe with some ingenuity some could make a transmission and oil cooler to be used with this system. This would allow better use for track temps. This would allow direct air cooling on first stage and secondary cooling for fluids. So maybe not ideal but my conclusion would be maybe benificial if used right. By the way just decide to post theoretical options. Not trying to start arguments. Just provide possible solutions!

I'm not arguing; however, it is my opinion that it will not work well for anything but drag racing/half mile/mile racing, very short bursts. I did not say it flat out won't work... I just see money and weight being better spent elsewhere. Everything designed anywhere in any market, has compromises, depending on your goals, that solution may be PERFECT for you.

BTW, i'm not that sure that switch to alu rads happened mostly due some alu rad efficiency rise and closing to performance of copper rads that are supposedly lagging behind due solder containing lead. Rather imho main reason for switch was steep rising of price for copper as material in later decades. Copper (not brass) rads usually with rest being same are more efficient, but 1) metal itself heat conductivity imho is not the bottleneck in rads, 2) slightly better cooling is certainly not worth multipling cost, when one can simply optimise a bit rad shape/increase heat exchange area and so on to compensate material differences for way cheaper. And then one can multiply those savings by numbers of cars sold. Given how bean-counters at some manufacturers often try to save even on much cheaper parts/options compromising many areas ..
I don't have any numbers to proove this, just basing my subjective opinion from what i learned / experienced / found out from liquid cooling PCs. There people usually value most noise reduction/low air speed & pressure cooling efficiency, hence it might be different in automotive cooling applications, where noise under bonnet matter way less and maybe i'm simply doing mistake applying experience from different field.

Something to keep in mind for boosted guys running full E85, there comes a point where the charge air is too cold and you will not get a good burn, and actually shoot snow out of your tailpipe. Alcohol fuels themselves have the ability to cool the charge air enough on their own that often times a charge air cooler is redundant. This was touched on in the OP. That, and ethanol in a direct injection application has an effective octane rating of 160!! I should also mention, the more alcohol you burn, the hotter your plug needs to be.
