Thanks for putting this comparison up. Hopefully we can get some more people to contribute.

Definitely want to see the CXR and Godspeed here.

I'm not alone....I cant decide and probably wont until I decide to do the turbo upgrade. I'm worried with a bigger FMIC the pressure will drop and my little tiny turbo will have to work harder to flow the same amount of air. I want the upgraded FMIC when I purchase a bigger turbo. PM if you guys have any input on that.

This is from a previous post in my Treadstone TR8 diy thread:

I ran my first datalogs tonight. I drove around for approximately 30 minutes to ensure the car was thoroughly warm and then I ran five back to back logs. I never turned the engine off and I only stopped to save each log and then I immediately started the next.

Ambient air temp: 48f Engine temp: 195f

Over the five runs here are the average charge air temps: Low Temp- 47.6f High Temp- 66.1f

Average temp increase: 18.5f

Lowest temp increase: 15.86f

Highest temp increase: 22.36f

These runs were ran in 4th gear from 2500-6100 on 23psi.

Here is one of the logs: http://www.datazap.me/u/14stred/7?log=0&data=1-2-12-14

Which core was this?

If you want to see logs from a DIY fmic I've posted 25 of them on the spark plug option thread. FSW tune, Cobb tune, stock plugs, NGK plugs, 3rd gear pulls, and 2-3-4 gear pulls.

Great explanation but post up the log.

Treadstone TR8 intercooler on my GTX2867R ( 339 whp pull ) This was in 4th gear, on a dyno with fan about 3 feet away. Not the best conditions for testing the intercooler.

Started at 1546 RPM @ 64.6 and ended at RPM 6714 @ 85.8 This was a 4th gear pull. Boost 25/26psi midrange, 27 at redline.

Overall rise.... 21.2

Need a datalog to go with that. CATs are dependent upon a number of variables, boost being a big one.

I added a link in my post for a log.

here's a pull of mine with a Buschur Racing FMIC, stock piping. around 3k rpm in 3rd gear, started at 18*C, ended at 6900 rpm and 23*C.

 

[Whiteblurrvt]

So is cobb fmic and cpe the best?

 

[bobby9621]

I have the CP-E so I am bias but of course it is the best lol

 

[casanova1012]

Whats wrong with the stock intercooler? Is it that shiitt?

 

[theogenemills]

Whats wrong with the stock intercooler? Is it that shiitt?

Over four 4th gear road pulls with Randy's AP 91 tune, intake pipe, green filter, and stock IC I averaged a 55* rise.....so yeah it is

They are the top 2 yeah... Both are damn good

Stock intercooler is a joke

Okay since no one else is bringing it up, I will.

Lower charge temps from your IC does not translate to more power. Pressure loss is key!

These comparisons temp drops are useless. You can have a core that cools 10 degrees better than another but if you are losing 1-2psi then you are pissing power out the window.

With that said, I'd like to see pressure drop comparisons between these cores. That is the only relevant information for determining IC efficiency.

The Godspeed FMIC has a pressure drop of 0.2-0.5psi @15psi and 2-3psi@ 35psi. That isn't too bad but it isn't great either.

I don't know what the CXR core does because they dont list it on their site

 

[shogodz89]

The GSP intercooler sees an average increase in CAT of about 10-13 degrees. It keeps the temps nice and low while also maintaining some decent efficiency.

MAP sensor location also matters as I have just found out. My GSP core has the MAP sensor mounted to the end tank while every other one I've built for people has it mounted to the outlet. The result is that I see 20 degrees above ambient during a full 4th gear pull while others have seen only 10 degree increases. Food for thought.
