Lightbulb Front Mount Intercooler Question

Hey there all WRX owners! I was wanting to get a Front Mount intercooler soon and didnt know which one would work for me...I have an Injen Cold Air intake--I was wondering which is the best front mount to get that I could still use the Injen cold air intake with, and also still have the front mount be big enough to fit my zerosports front bumper and still look nice. I originally wanted the MRT front mount but heard that i had to use their intake pipe.
Thanks a bunch!

I wouldn't suggest a front mount intercooler unless you're running a larger turbo, fuel pump, and injectors. In my experiences, i've seen people actually lose performance without having enough turbo/ fuel enrichment mods/ engine management.
I know they look cool, but a well designed top mount can easily outperform a front mount when using the stock turbo or even a slightly larger turbo. Most front mounts come with their own inlet pipes. Let me know if i can help.

It sounds like you are very attached to your intake, but the truth is, a Front mounted intercooler makes inlet air temperatures almost moot. You see, with the kind of intake temperatures a FMIC is going to give you, your intake temp will be ambient almost all the time. I didnt believe this to be true until I saw it for myself. Bret is correct about bigger turbos and injectors/fuel system. The FMIC will immediately make you very lean, especially on the stock ECU. On a WRX, I would recommend NOTHING smaller than a VF30 or equivalent to drive a FMIC - otherwise you will lose performance and have atrocious turbo lag.

Heres a pic of mine

If you are absolutely set on keeping the intake, get a big top mount. TurboXS and BPM both make nice top mounts that will considerably increase your flow.

PS - if you want to feel a car with a FMIC, there are several of them around.

My advice is as follows:

First off I echo what SubeTek and Jama said about there being NO NEED for a FMIC unless you already have bigger injectors, BIGGER TURBO, etc...

Here are my personall choices of FMIC from the research I have done.

1) My favorite is APS Cobb FMIC - it is the most expensive AND you have to buy their CAI to make it work but here are the good points:
-They don't use metal tubing under the hood to route the plumbing, they use the samco tube type stuff = cooler charge from less heat absorption
-It DOES NOT require you to hack away your metal bumper support... you know that thing between your engine and a guys trunk bumper

2) Blitz is the one Jama and WRXThis run and it's the cheapest but it does require a lot of cutting of the bumper support, they occasionally have issues with things like heat and leaks becuase they use metal plumbing under the hood bonnet.

Just an FYI I personally tested my airtowater intercooler today to see how much pressure drop I get on my VF22 @ 17psi @ 6000rpm's and I only lose about 1-1.5psi through it . I was thinking about getting a FMIC but Cobb's is the only one I can find info on on how much pressure drop they get and they claim "a little over 1psi pressure drop at 7000rpm".

Anyway enough for now

Cheers

ElogyWRX17,

I am not sure what other mods you have done thus far, but I would recommend optimizing the exhaust flow first and then the other things i.e. turbo-back exhaust, up pipe, flywheel, Vishnu unichip, electronic boost controller, STi injectors then an upgraded intercooler if not in combination with a larger turbo. The new MRT top mount has the best flow of any on the market today, definitely something to think about when you are ready upgrade.

Talking Thank you, Thank you

<Subetek><WRXThis><Jama><DavidM_sh><T-WRX450>:

Thanks a lot for all your guys' knowledge on this information it will be very helpful when i do all of this stuff...

I've got some other questions i hope you guys can help me with in regards to your replies...

My other mods on my car are an HKS Carbon fiber hiper exhaust cat-back system, an HKS SSQ BOV, and an Apex'i TT.

I was planning on getting the upgraded turbo being a VF22 or VF23--which would you guys prefer? As for the fuel pump and injectors--which would be the best kinds, and where is the best place to get them?(In regards with working with my present set up.

Thanks for your time!

Well, the VF22 is out of production officially this year, but you can still get them. However, the VF22 has had some issues with bearing and shaft imbalance causing bearings to go bad every 20-30K miles or like wear, so if you get one make sure that you are prepared to rebuild it every couple of years.

The VF23 is a great turbo for the moderate horsepower minded, but if you are going to pair it with a FMIC get a small front mount like the APS or similar. Personally, I would go with something like a PE1818 or VF30 or larger turbo with the FMIC to really take advantage of the flow capabilities of the intercooler. As for fuel, get injectors first and a fuel pressure gauge and see if your pressure drops. Sometimes at altitude fuel demands are not as hard as they are at lower elevations and you can get away with the stock pump. If you are going to get a pump, get the Walbro - there are about 75,000 places that sell them online. They are cheap and work really well. Injectors are available cheap in the vendor classifieds on this board from around $400 for the 565cc ones.

Have you looked at the Godspeed downpipe? It would be a nice complement with your HKS exhaust system and would elminate more cats.

Before you do any of that stuff, I would get gauges and some kind of adjustable engine management like a Link, Unichip, FCD and fuel computer, or whatever you choose.

Are you going to be using a FMIC with the mighty turbo you'll be using?

Hey there COwannago:

Yeah, i guess once everything is set-up right(hopefully) the FMIC will be used
