Hahns FMIC Install

[yellowkyd278]

Hey everyone,

I just picked up a Hahn's Racecraft FMIC (H IC-1200) for my 2g. It's the highest flowing one they've got that they're pretty famous for. Anyway, I've been reading up install VFAQs and other threads but none seem to be specific to this the Hahns.

Anyone know of where I can find its VFAQ or can anyone point out a FMIC very simliar to it (i.e. SBR, Dejon) in which there are threads and vfaqs that exist for the installation?

Any help appreciated, Thanks.

Put it by test fitting each peice first. If some stock part gets in the way like the bumper then cut it to fit (the bumper not the IC).

There really isn't much to it. The only thing that a vfaq might be useful for would be figuring out how to get the front bumper off if you're having trouble with that. The easiest way that I found was to remove the four bolts (two on each side), that run through the rails that hold the bumper support onto the body of the car. That way you can just slide the whole entire bumper (support still attached) straight off the car (after of course removing a few plastic clips, disconnecting lights, etc.

The Hahn kit should have come with instructions that pretty much tell you what needs to be done.

Once the bumper and bumper support are removed you'll need to fit up the intercooler. You'll probably also need to move the power steering cooling lines, I needed to. If I recall, I pushed mine back a bit so that they sit behind some support peice that runs vertically. It'll be obvious when you're looking at it. Or maybe I tied it to that... don't remember without looking (I seem to recall a hammer being involved ). But really, just mount the intercooler so that you can figure out how much of the bumper support and bumper you need to cut out. You shouldn't have any issues with piping since it all follows the same route as the stock piping. Again, just mount everything up so that you can figure out what you need to trim for for the bumper and bumper support to fit back on. There's not much more to it than that.

Have fun cutting through the bumper support though. That sucked. That thing is thick. As I cut through it, the cutting wheel would heat it up so much that it fused itself back together as I went forward. hehe.

...and if you need any help, I'm also in San Jo, have all of next week off work and will probably end up getting bored very quickly.

I so want that IC too, let us know how it works out for you.

It doesn't flow that well. The pipe that runs underneith the IC pretty restrictive and the end tanks are too short.

We really need to hear from guys that have this FMIC and see what their thoughts are.

About halfway down you'll notice their test senario.
I've never seen any other FMIC manufacturer post their test results on their website other than DV-DT Fabrications.

Hahn states that the integrated cross-over tube has a cross-sectional area equivalent to a 2.5" diameter tube.

.92psi pressure drop sounds pretty good to me, most others are around 1.5psi pressure drop.

Have a look see... and feel free to enlighten me because buying a FMIC is a pretty big purchase.

I've had one on my car for a couple years now. I first installed it when I still had the t-25 on the car, moved on shortly after install to an EVOIII 16G running 20psi daily with wonderful CA 91 octane. It does the job, and seems to do it pretty well. Even during summertime. I've never had any cooling issues either. Apparently plenty of air still gets to my radiator with this beast blocking it.

The core is nice and also pretty tough. It's stood the test of time and taken the abuse of being daily driven (minimum of 70 miles a day), even during construction on the local freeways with debris and gravel pelting the thing at 80+ mph.

Quality is top notch. They make install a breeze (2Gb's get to keep their foglights), and it even comes with a decent set of instructions. I don't know what else you could ask for (well at least in my case). I'm sure there are better setups out there for different applications, but this FMIC works well for my setup.

, I knew it.
I have the GReddy 18g CARB legal, and it has an elbow welded to it, so it looks like a T25 on roids.
The 3" intake pipe is also CARB approved, so I'm stoked when it comes to smog season.

I also have the GReddy UICP's.
From what I've read, Hahn supplies the end user with LICP's to get you up to where the stk SMIC exits.

I plan on running under the smog nazi radar with either a PTE BB 50 trim, or a Borg Warner ETT 50 trim.
I'll have an elbow welded to either one of the comp covers and also retain my stk heat shields .

Thanks for the info Module Unkknown.

I chose Hahns because of their reliability, success stories I've heard in the past and their proven numbers. Secondly, it's a quality product, fits well and flows well enough for MOST turbo options.

For me, running at 16g practically any FMIC would eliminate heatsoak... including the E-Bay ones. However, I know with this FMIC if I ever choose to upgrade, I'll be in a good place. Hahn's is a safe bet for a good price. I'll keep you guys updated but it really wouldn't be posisble for me to run into any flow problems. That's that =]

Happy holidays!

Hmm... seems you Californians don't really care about any real perfomance, at least straight line. Too bad your veiws of what makes power has been deluted by your fear of your state's smog tests. Too bad for you.

How exactly were you able to come to this conclusion? If based solely upon the information found within this thread I would have to think that is an uneducated assumption. The grammatical and spelling errors alone help point toward uneducated...

Out of curiosity, what exactly is the official definition of "real performance?"

 

[yellowkyd278]

Hah that's definately an false generalization. I run an test-pipe as do many others and that'd fail smog miserably. Hopefully you're not assuming that I using an evo3 because of smog. While I do like going to the drag strip and in a straight line, I prefer actual track days and driving hard for more than 12-15 seconds at a time. Any of the larger turbos kicked in too late and too suddenly for that type of driving and the Evo3 was a good compromise. In the future, I do plan on going with a stroker + a bigger turbo but at the moment I'm happy with where the car is at.

It's alright if you don't believe the Hahn's flows well and I posted the thread not to defend it but to take suggestions. From what I researched before I made the purchase, almost all the performance shops I talked too (RRE and Slowboy included) said Hahn's was a good way to go.

It sounds like you had trouble when you ran the setup or know someone who did. What turbo were you or your friend running along w/ the FMIC? Did you run into heatsoak? Using data from a logger, how much of a gain did you receive when you swapped to a different unit? And finally, what FMIC would you recommend instead? We could go on forever saying "Hahn's is bad" or "Hahn's is good" but lets try to make this thread somewhat useful for readers and future buyers.

Okay.
I was in the same situation as you.

Here is the end all be all for this situation.


Hahn sells an AMAZING intercooler
but not for the price.
I can say this because i've done months worth of searching and research.

If i were you i would go with www.extremeintercoolers.com
the 7" kit is more than enough for the 16g
all parts to make it go from your turbo to your TB AND you save $300
Bar and plate too!

my advice...
Go talk to JR (not junior), hes a nice guy who will more than likely talk your ear off about intercoolers.

You can get the Hahn kit from Nopionline.com for $873 + shipping.

Well... let's see. The fact that we are even discussing the outdated design of the Hahn kit leads me to come to this conclusion even though I was joking before but lets get into this shall we? Anyone who knows anything about hydrodynamics could tell you many of the FMIC kits that are sold are made based on fitment alone and not to generate power. What happens when water (or air) flows into a sharp edge? It creates turbulance and restricts the rate of flow. This includes about 90% of FMIC on the market that were just slapped together (square endtanks and a core) but the Hahn design is even worse. The air hits a wall and must change direction using its own pressure to divert itself through another tube. A 180 degree turn is never good for power. If it were, I say try it on your exhaust and see what happens. Cooling is only one part of making power. The amount of flow in and out of the intercooler is even more important. I would use a smaller core with larger and better flowing end tanks any day. Sorry, I'm not an english major.

I have the hahn and it works great for me.
installation was a snap, honestly how could you need vfaq instructions, they give you a set when you buy from them, and the only part that requires a tiny amount of thought is mounting the bolts in the foglight brackets, and some trimming of the front bumper.

 

[pickens]

My hahn was good for a 12.8 @ 113 mph on bfg street tires and mix of 91 and 100 octane. Not bad for a fwd. Mods in the profile. Seems like it makes power to me.

The only thing I didn't like is more lag. But that has more to do with the hahn being larger than the ol supra side mount I had.
