The suspense is killing me. LOL
If you guys are seeing higher than normal temperatures before the IC, it could be that you're pushing the compressor too far to the right on the (nonexistent) map, into the 50% efficiency region.

Again we (inverted and I) have already verified that with 1 1/4" lines, the big rule pump (3400 I think) near 40* water temps and 75* IAT at start of run we saw a 50* rise in intake temp at only 12lbs of boost on an 1/8 mile hit. With that said boost wasn't even steady at 12... it was tracing rpm and would dip to 6lbs on the shift and peak at 12 at the top of the shift.
Even though we don't have super solid 1/4 full boost data I'm going to say that this cooler is garbage based on that info and my past experiences. I fully expect to see 100*+ rise on 15-18lbs on a 1/4 mile run. For any of you who are considering this cooler I say run. My $80 eBay A2W which by the way is THE EXACT same thing as frozen boost blew these results out of the water.

Here's some numbers for you guys to play with on efficiency:
Ambient was 60F . Beginning AIT 65F. Water temp 60F. 8.2 second wot hit. Ending peak AIT was 80F. 12psi boost.

From that I get 85+% efficient. Anyone else want to take a gander?

But really the compressor outlet temps were lower then expected and the efficiency of the intercooler core was also lower then expected.
What size lines and pump are you running?What is the compressor outlet temp? What size turbo? What size engine? Why are your results so much different from the gentlemen above?

Patience my friend. This is the painstaking part where I want to actually want to know why what is happening, is happening. Some guys have great temps, some guys don't. This could possibly run deeper than a definitive "it works" or "it doesnt" There are a lot of variables here. I can tell you right now, mine is not 85% efficient, and it's not even close. That'll have to hold you for the time being.

Give me ambient/inlet pressure and temp and pre IC pressure and temp and I'll tell ya where ya are too.
I know you guys didn't set up for pre IC pressure. Might consider it if your getting into the numbers and all. Gonna need a 4 bar sensor anyway. May as well get 2.

But, we can calculate the pre IC temp with the assumed 76% efficiency and provided ambient temp and boost.
[QUOTE=onfire;19576916]
Ambient was 60F
12psi boost
76% on the island

So after he jumped through all the hoops spending buckets of money he still had numerous logs that said it wasn't working properly. But they dismissed his data because he didn't have pre intercooler temps. But you know what he jumped through that hoop too and now that we have inlet temps, pre intercooler temps, post intercooler temps and the data it shows is how much of a pile of **** this thing really is.
The funny thing is they could have avoided all of this if they had some decent customer service. The OP tried multiple times to work with these guys. But instead LJMS sits back at the end of the day and says if you don't like it you can sell it to someone else. That's the support you get? Think about that for a second before you consider buying this product or any other.

I hope you're not talking about me, I have nothing to do with any company or manfacturer.

Consider your boost is measured post intercooler so there is probably at least a 1-2psi drop there and I doubt the turbo efficiency is that high, so lets call it 14psi of boost and 70% efficiency, compressor out is 216F.

Not you at all I'm talking about 417MS and LJMS. They kept coming up with excuses as to why the core wasn't working properly: he needed 417 water manifolds instead of fittings, he needed larger lines, he needed a better pump. You wanna know how much difference all that **** made, 10 degrees count'em 10! Over $1000 worth of **** to drop 10 degrees, crock of ******* ****!

I must have missed it which I don't think I did since I'm fully cracked out on needing to know what the result is lol.

60F ambient, 76% efficiency (Which I think is too high) and 12psi boost, compressor out is 187F.
Consider your boost is measured post intercooler so there is probably at least a 1-2psi drop there and I doubt the turbo efficiency is that high, so lets call it 14psi of boost and 70% efficiency, compressor out is 216F.

Applying the figures to:
84% IC eff at stated values
87% IC eff at speculated values
Mr. gtistile's estimate was right in there. Thumbs up
