Anyone running one? Did it make a difference in power? 1/4 mile times?

Most have given up on the killer chiller and gone j2fab cooling mod.

I had a KC for a long time. I never had any issues with mine, worked great, cool IATs and still had cold in cab AC. I swapped over to the J2fab flow mod to not have to have my AC on all the time, plus worry about dripping water at the track.
Don't combine the two, several people, including a friend of mine tried the trunk tank with killer chiller and had problems. Too much fluid volume for the KC to effectively cool. I haven't had any chance to drag race my cobra, but on the dyno i did three runs back to back and my IAT2 went from 96-102 max temp in three back to back pulls.So has anyone ever proven that the J2Fab actually works? There seems to be so much conflicting data on this. In theory it would seem to work but not sure about in practice. It seems you have to have a trunk tank to take advantage of it and it seems people with trunk tanks are already cool enough not to need it if that makes sense. I was thinking about it but a few companies are talking about making new lower intakes and intercoolers so may wait for them.
This is for sure one of the biggest weaknesses in my build and I have gone over my cooling system a few times and I am still not sure if I am happy with where I am at with it. I debated hard on the Trunk tank VS Killer Chiller Vs combining the two.

Not sure why.. My intercooler temp is generally 30* below ambient in the summer time.
Other than my Tvs it was the best mod!!!

Malcolmv8 did some testing and posted a video on Facebook. Testing the flow difference in a stock intercooler and a j2fab intercooler and the j2fab flows 50% more coolant. He also tunes cars regularly and had told me j2fab cars drop iat2 temps when under boost. Others on Facebook have said the same.
But when you get on it does the temp stay down during the course of a run?
People complain that the kc might give you cold fluid to start a run and cold fluid shortly after a run but during the run temps are climbing because of flow through the intercooler.
Correct but don't forget I can keep my fluid in the I/c system well below ambient temps right onto the staging lanes... I/c temps on any system will climb up during wot.
I just love the simple fact that my I/c fluid is always ice cold and I always use the a/c system in my car... with a stock i/c
Ya I under stand that it does in fact flow more but that is the debate. Cooling comes from the amount of time in the heat exchange. The reason we have 2x, 3x pass through heat exchangers and more surface area. If you flow too much you are not giving the coolant enough time in the heat exchanger to cool therefor you are actually just recycling heated water quicker never letting it cool where as when you add the trunk tank you are going from like 1/2 gallon of water to 5-7 gallons of water which is where the cooling is really coming from. I know people with trunk tank only and claim sub 105 temps after pulls.
So I guess I am saying have people done normal aftermarket under hood tank, then did a trunk tank only, and then did J2fab and if so when did the big cooling gains come in? Is the J2fab worth the $700 or so over the price of a Trunk tank? I am not trying to be negative, I am just trying to learn because I am not a fan of my setup and I run a lot of boost.
So you didn't read where i posted that j2fab trunk tanks with big pumps report iat2 temp drops under wot?

FWIW, there's a company called Department of Boost. The guy that owns it is all about the air to water technology. He's made some custom lower intakes for the S197's and S550's. He says the more flow the better. And according to his customers his set ups work well. I was trying to find something he posted about the Veyron has an intercooler flow of something like 200gpm.
YMMV.
