nice, seems like a very comprehensive test.
someone should convince NISEI to test the Ebay IC, or maybe they don't view XSP IC as a real competitor.

Yeah amazingly the NISEI unit is so good it cools inlet temps to BELOW AMBIENT TEMPERATURES! It doesn’t even have to follow the laws of physics, I mean that is amazing. It’s almost as if some sort of refrigerant was used……


IDK…. It is by far the best looking unit I have seen, but those inlet temps are not possible.

Honestly though, in the last link if you look at the core design the Buschur intercooler's turbulators look just like XS Powers, while the Nisei's turbulators look like a Precision, which is a garret core. The reason I know is because I was comparing them today. The Buschur core seems it would be fine for a drag race like the XS one, but as far as road racing you need a core that is like the Nisei, because the air will hit more turbulators to cool down rather than hot air just flow straight thru. I will post pics of the XS power core and the precision core just to show pics, my buddy has them both at his shop and then you will see what I mean.

it's odd that NISEI mention how there ICP weigh half as much as Buschur but they didn't say anything there Mini battery kit weighing 10 times more than Buschur

Few things. The Nisei intercooler is outdated and incorrect. Let's just cover the incorrect parts first. Number one the intercooler they tested is our very first design of the Deluxe FMIC, which has the one piece outlet pipe. Second, that intercooler was built from a Spearco core. So those two are just facts. Even when that test was posted it was outdated. We had already continued to improve and change our products and back when that test was performed we had already changed to using Garrett cores, which is what we have continued to use to this day. The Garrett cost us more but outperformed the Spearco core.

The lower i/c pipe is had also undergone a design change, which is not on that site.

Last, I am not going into any pissing matches on this subject so I am going to state the facts and leave it at that, is their testing is not/was not accurate. An air to air intercooler is NOT going to cool the air below ambient which is what they are trying to pass off in the testing of their own intercooler. While their testing seems very good and legit, it is not.

if the air is expanding then it's possible to go below ambient no?

I've seen frost bands form on piping due to the rapid expansion of a gas

I think it's the Joule-Thomson effect?

i do believe this is correct for O2

what i don't know is how much of a temp change could take place in the intercooler...and if there is then it would have to be due to a pressure drop across the cooler, you should only be dropping a couple lbs. i would hope...maybe someone better at math/physics could run thru the equations?

N2 and O2 both cool down when expanded at normal temp

it's true for any gas.
when gas is compressed, it needs to give off energy (hot) and when gas depressurize, it needs to absorb energy (cold). this is how an AC work. but there shouldn't be any depressurize of gas inside an IC while in boost and the whole system is under pressure. the only place where gas is being decompress is at the bov when you lift the throttle.

i just can't justify, buying my car for 30 k and then half assing the parts i buy for it. Hey maybe i should start shopping at pepboys for performance parts and put GT-R emblems on it.

Rapid increase of pressure would increase temp.
Rapid reduction of pressure would decrease temp.

not true of Hydrogen or Helium not that it has anything to do in a car...also according to the vendors you are depressing the air in the intercooler, it might be as small as 20lbs in and 19lbs out but it's moving a bunch of air so that could be the cause of the <ambient temps on the outlet

still 18 pages of nothing but guessing

well I just found this in a thread I made over over a year ago about this same intercooler someone tried to sell me and this is what AMS wrote...

He is indeed a great guy but this is not the same an AMS unit. these have been proven to lose hp over the stock IC. We tested this core 3 days ago and on a 320 whp car the AMS ic picked up 10 more whp over the XS power unit.....hardly the same. For more information on the XS power core and its drastic differences in design and function you can read my thread in the AMS forum entitled "ebay buyers beware." The XS power core is a knock off and their claims for power (the exact same as AMS) are false.
