awesome, thanks for the link

 

if the water bottles dont work at least you will have a contingency plan for them when you get the dry ice lol

 

The problem with putting ice in or even ice in bottles from what I gather is it just melts too fast. If you put it in before lining up at the track it will be completely melted by the time you are on the starting line.

....anyone ever done a giant peltier type cooling?

 

really? you want the ice to melt so that it is transfering heat, but I would think with a dedicated air to water cooler that all of the ice would not be melted if you push it to the line and add right before the run.

 

Pat (evilgmc) tried that frozen water bottle thing when he went to the track last weekend and he said it was all melted in 3 minutes. Heat transfer is related to the temperature differential between the two things, in this case the ice and the coolant. The colder the stuff you put into the coolant the faster it melts. Its a differential equation depending mainly on the temperatures of the two substances, the thermal conductivity between them, and their specific heats to define what the temp is....which is way more math than I want to do right now

 

yes...i tried 3 8oz water bottles. did not last more than a couple minutes...3 gallons of hot fluid vs 24oz of ice...ice did not stand a chance. plus it was a pain in the *** fishing them back out of the tank....if i did try it again, i would tie a string to each bottle.

maybe a NOS spray bar for the HX would be a good investment.

cant wait to get the methanol all set up...not going to lower temps, just will allow more timing.....with it, i think i would have hit 11s even with the **** weather and a ton a crap in the bed of my truck.

 

throw in a nitrouts nozzle, ya know, just in case....

 

Pat, how long did you let the engine cool down between runs? I'm just curious. I won't be able to try any of this new stuff out for a couple of weeks, so I'm stuck bench racing.

 

actually you have latent heat and sensible heat, latent heat is not measurable by the temperature scale and sensible heat is. you are correct that that the larger the delta T the faster heat transfer but that does not mean that the ice will melt faster the colder it is. You have already touched on other variables so I wont go into them again. But the latent heat can carry alot of BTU's increasing the length of time before reaching the latent heat of fusion

 

So, get a dead blow hammer & whack the **** outta a bag of ice, til it's into tiny pieces?

Got any vids? Why does this occur? I haven't had chemistry or physics, so keep it simple.

Couldn't ya just get the coolant cooler, or try to, how IDK. Or get the temp. betw. the 2 as close as possible.

Pat, I was wondering when someone was gonna say that. I figured w/. bigger bottles, them floating outta hand's reach would be less of a problem.

I'm exploring options before I've even put my Radix on.
I've been reading the many threads on this as I can too.

I wondered if it was worth it for a mostly DD truck that'll see track maybe 1x a month. Maybe twice, here or there.

I didn't know if a bigger HX or a bigger reservoir would be the better solution.
Sounds like a bigger (or better if u like that word) HX is preferred. I got a price on a bigger HX.
