View Full Version : Boost Factory SMIC ---> too big for k03?

Boost factory has developed a replacement Side Mounter Intercooler that outperforms the top FMIC's out there with the advantage of keeping everything stealth and in the stock location with little to no trimming. Here's what we've found: The proper way to test a intercooler has more to do with the temp diferential between the inlet and the outlet than most people realize.You cannot draw any conclusions with just the intake temp logs. The proper way to test this is to measure the max temps of the inlet and outlet on the intercooler and ambient outside temp.This can be done with a K type thermocouple and a good multimeter thats designed for use like this. Once you get these measurements you can use this formula. (temp in-temp out / temp in-temp ambient)* 100 = Thermal efficiency Here are the real #s that were collected today during the test. BFSM temp in = 235deg F temp out = 85deg F Stock SMIC temp in = 235deg F temp out = 105 deg F Anbient temp = 35deg F So what do we have? BFSM (235-85=150 / 235-35=200) =.75 * 100 = 75% Stock SMIC 235-105=130 / 235-35= 200 = .65 *100 = 65% Another side note is the 4+ psi pressure drop of the stock cooler and the unmeasureable drop of the BFSM. Another interesting link is the APR site that has enough info for you to draw some interesting conclusions.I do notice they dont mention the ambient temp or the intercooler efficiency.My conclusion from this is that it would take all the same info they provide+ some damm hot ambient temps to equal the BFSM We tested this BFSM and found it to flow 491cfm@1psi pressure drop This intercooler is good for 400hp *Keep in mind that these units usually take about 2 weeks to make as they're custom orders. Specifically developed for the Golf/Jetta mk4, however now also for the B5 Chassis cars such as the Audi A4 and VW Passat. Measurements: 6" x 8.1" x 8" Flow: 491 Cubic Feet Per Minute (CFM) Choosing the correct MAP sensor size: SMALL-2000-2003 including VW GTI/Jetta 1.8T/TDI, VW GTI 337 (NOT 20AE) LARGE-2003 VW GTi 20AE, 2004- VW GTI/Jetta 1.8T/TDI including GLI We will now ship all Golf/Jetta SMIC's with an adapter sleeve to fit both small and large map sensors.

I've heard they're big enough to support GT28R's, but their product description makes it sound like they can be run on k03's. If it's a 400hp core I know I should generally have those mods... soo is this thing too big for a k03?

If it is, what are some other options for lowering IAT's on a k03? I know of w/m injection and intercooler misting.

I dont understand why people with k03 want to change their intercoolers. There will be no noticable gains. Not worth it.

Not for power, to reduce loss of power. It gets over 115 degrees here in the summer regularly.

I have it on my k03

I've not suffered any noticable power loss, or MPG loss

infact the cars seems to go into boost much faster now

I bought it cause I'm planning for the future which includes a non k03 turbo

I've got nothing but positive things to say about it, I installed it a few weeks ago and I haven't had to change one thing about it

install took a grand total of 45 min too

although I have a fmic I think I'm going I get this sooner or later

Kyle H
04-22-2008, 09:29 PM
If I'm thinking about this right, the BF SMIC can support those bigger turbos because of higher flow, not higher volume, correct? And the bad thing about running big fmic with a k03 is that they have a huge volume that the k03 can't fill... right?

I don't claim to be an expert on these things, but I don't think that the BF sidemount has less internal volume than most front mounts

the pictures you see may not accurately portray the size of the unit

its almost cubic in shape

I would love to run one of these for the stealth and ease factors, but i am still leary of just how good it is. Proper ducting could really help i would think.

Note cars with headlight washer may have issues fitting this and may have to fit a the smaller non washer bottle to get this in.

The washer reservoir are the same size. I've had both since I eliminated my headlight washers and switched to the other res.


A K03 or K04 need a good intercooler as much as a gt28. The little turbos go out of their efficiency range and start blowing hot air quickly. A few hot laps on the track and my K04 maxes out around 5-6 psi with the stock SMIC.

I have done allot of research on this before as I was planing on upgrading to a bigger smic because I like it to be stealth. The boost Factory is good but the Tyrol Sport is even better you might want to check it out. Its more money but It might be worth it. http://www.tyrolsport.com/index.php?p=product&id=45&parent=95

Looks smaller in the pic than it really is.

There is also this pic which shows what it looks like in size difference but this one if for a beetle.

For the price of the tyrolsport you can get a racetec front mount for 800. I think they'll even paint it black for you if you want to be "stealth".

Ya I know what your saying but some people want it to be stock stealth and to now have to trim up their bumper. I think I am going with the racetec when I get the cash seems thats the most preferred one if you don't mind spending the money on a good one other than ebay.

when I put mine in I sliced up the stock duct and made it fit the new intercooler, I'm also using a S4 fender vent

I think that was just Robbie's weird 2001.5 car

it fit no problem in my 97 with the 2 part washer bottle

I just read through the car classifications for SCCA auto-x, and an upgraded intercooler bumps me up into the next category (with all non-stock-turbo cars!). I could probably get away with saying the bf smic is stock, but that would be cheating...

Are there any other options for lowering iat's other than w/m injection and intercooler misting?

Vreihenmotor6
04-23-2008, 12:39 PM
unless you told them it would be hard for them to tell

http://img.photobucket.com/albums/v116/vtecthissucker/snap129.jpg

expecialy if you painted the endtanks in a black wrinkle finish paint

if its only for auto X maybe you just get a small c02 bottle with a handheld wand nozzle to stick in your lower grill and cool down your stock IC between runs

if a modded IC isn't legal I can't see how water injection would be

Huh? It sounds here like you're disputing docurley's point that cars with the single, larger sized washer fluid reservoir will have trouble fitting this. He's right. The larger reservoir takes up SO much space in that bumper that the BF BAMF SMIC is pushed forward, down, and to the left so you can't make it fit.

I've got an uninstalled intercooler that agrees with me on this one.

There must be more than two different reservoirs out there then. The two I've used were the same volume and same shape with the exception of the headlight pump mount.

If any one has logs i would love to be enlightened because i have inqquired since 05.

Yeah, but I have standing comitments on sat, or else I'd defiently be down to see what we could do to that tank to make the IC fit... including hack sawing of course.

it could be just another case of the 2001.5 screwing the owner, but what I was told when I checked a person who works the parts counter and is ususally spot-on when it comes to this sort of thing. He said there were just two setups... single tank (mine) and dual tank (older?) and he thought it was something that went along with the face lift.

I haven't delved into ETKA too much myself on this, as I was just going to replace the tank and lose the washers. At a bare minimum, before anyone tries this they should pop the bumper off and see which tank they have.

well, I do have that plastic welder to "uncut" things with[;)]

I will still maintain my it will fit as is position untill I myself have tried[wrench]

Not trying to be biased here but you have no facts to make your judgement on, put them side by side with all things being equal if you want to get good data, otherwise your oppinion is just as vadid as the next guys, et, etc, etc.

BT and Tyrol both use Bell cores, the rest is up to you to decide as the numbers are out on both sidemounts.

Hope that helps. [up]

Can you post some numbers up from the BF UGSMIC on a a4 or passat application?
I heard good things in reference to the transverse applications but have yet to see data from the longitude engine.

If you have stock vs bf or bf vs tyrol or stock vs bf vs tyrol i would love to see.

Plus I would how effective it would be especially since not that much air is getting to it and even with vents in the liner is that enough circulation.

Not trying to be a prick just i have been curious for quite some time.

x 2, everything ive read on this unit is that its a waste of money

SilverB5A4

It is never going to be as effective as a FMIC of similar quality, the whole thing that makes a FMIC better is that it gets more direct airflow and has more frontal surface area.

04-25-2008, 07:54 AM
You guys really need to do some more learning on how intercoolers work. For normal driving they are as much a heatsink as anything. The opening feeding it only needs to be 40-60% of the area of the intercooler itself for great efficiency. There are a great number of reasons that the cars like the B5 RS4 and Porsche 911 Turbos come with dual SMICs instead of a FMIC.

Yeah, three tanks, like I said...

Older style = dual tank, one in the fender, one under the intake mani
Newer stile = larger tank in fender

that and packaging, as in how to fit all that stuff in a small space
