Has anyone done extensive testing on FMIC's? Specifically I'm wondering what improvements people are seeing in terms of loss in PSI pre/post IC compared to the stock IC, as well as temperature improvements pre/post IC compared to stock.


Specifically I'm looking for serious data spreads like what is found here from ETS:

But I'd like to see other manufacturers too.

I can start you off with this one:

Stock boost level
+15.4rwhp @ 5310rpm
+15.2rwtq @ 5310rpm

Pressure drop stock boost level

Code3 - 0.6psi @ 5350rpm

Upgraded boost level (14psi)
+26.6rwhp @ 6040rpm
+23.1rwtq @ 6040rpm

Pressure drop upgraded boost level
stock - 1.5psi @ 5950rpm

Dinan:
From their website: "Greater power gains are achieved with a larger high performance intercooler. The Dinan intercooler provides a 93% increase in total volume, substantially reducing the pressure drop by 0.7 psi, as well as providing more efficient heat exchange."

Helix:

Data compliments of TTurboBullett

stock intercooler at 13.5psi 63 degree ambient temps:
351whp
turbo outlet temperature- 228 degrees F(estimated using a 63 degree ambient and 65% compressor efficiency at 13.5 psi)
AIT temp- 129 degrees F
pre and post intercooler temp drop- 99 degrees F
Intercooler efficiency- 60%

Helix intercooler at 13.5psi 63 degree ambient temps:
372whp +22whp
turbo outlet temperature 228 degrees F(estimated using a 63 degree ambient and 65% compressor efficiency at 13.5 psi)
AIT temp- 75 degrees F - 54 degree drop over stock
pre and post intercooler temp drop- 153 degrees F
Intercooler efficiency- 93% - 33% improvement in efficiency over stock
Core pressure drop spec is .5psi at 450hp(600cfm) airflow

But please heed my advice... search first, next time :-) Thank you, in advance!

Most of what they have is IAT temperatures and info from manufacturers on efficiency. I'm looking to see if anyone has actually done testing back to back under same conditions of stock vs aftermarket, pre/post inlet/outlet temps and pre/post inlet/outlet PSI. I see only a couple of those data points mentioned in the thread, but even those aren't actual data. For example, helix mentions pre/post temp, though outlet temp was "estimated". In fact, someone even asks the question "what about presssure drops pre/post FMIC" and indicates that the thread lacks that data.

But I'll keep reading. Edit: I found some data on 2 of the many manufacturers. ETS had the only comprehensive data I was looking for so far, but I'd love to see that kind of data spread from the other manufacturers.

Beyond that, my searches instead turn up threads like this:

Where it looks like someone is actually trying to collect the data I mention, but it never comes into fruition. :/

But I'll keep reading through all 11 pages of the thread on the off-chance if it actually has what I'm looking for.

*sigh* ok look... I'm sorry I offended you... don't take it so personally. It's just a forum, lighten up a little... I took the time and found this in that thread I linked above:

Is that not the kind of information you are looking for? As I said before, it's a place to start -- not a bible guide to every intercooler out there to date. That will actually take some time to search. Before I bought my FMIC, I spent days searching through e90post... but all the information was there, that's how I know it's searchable.

Edit: Guess you beat me to it

It is sort of the info I am looking for. What what I'm really looking for is data exactly like this:

http://www.e90post.com/forums/showpo...7&postcount=37

While a single data point is ok, it's not a comprehensive view since the numbers won't be static throughout the entire rpm range, flow range, etc. For example, an FMIC won't necessarily have a .5 PSI loss at all times.

ETS is the only one I can find so far that has it, hence why I posted the thread. I know how to search, but sometimes even then the exact info can be difficult to find if I'm not searching the right terms. :/

Anyone has test the 6' ETS 20x5.5x6.25' fmic? Becuz that's what I got hehe
