what type of ics? for pj k04

[infinkc]

Rs4 ics?
FMIC?
Other?

[AudiSportB5S4]

look at the thread i just made for the FMIC cooling. im 3- right now, if you go to that thread you will see how shitty the stock SMICs are at cooling the air from the k04s lol. the FMIC flatlined the temps pretty much. the only downside to the FMIC is its up to you how you want your car to look. i like the look of the FMIC. if it bothers you and you want bumper support and all that then ER or AWE's would be the way to go probably. RS4's arent worth the boness

SMIC's defiantly are a better choice. No overheating issues at low speeds due to the core on the fmic obstructing flow to the radiator. (plus it gives you the sleep look still)

Go with either AWE or ER smic's. I would personally go with ER's SMIC's those things are huge and have been used on applications bigger than pjk04's.

Happy modding.

Go with AWE or ER side mounts.

Whats the downside of RS4 ICs?

FYI, jason @ JHM told me that all last summer out in cali in 110+ plus days had NO problems with overheating. i have an EFK that he recommends as well so maybe that helps a lot. ive had mine and it was 85 the day i brought it home and of course in some traffic, no issues at all. although its not hot im baking on what jason said.

to be honest idk, i mean NEW there is no reason to buy them lol. you can get AWE's or ER's for that price. also i heard they are annoying to get in there. i think the bumper will stick out a little or something i know there is some fitment issue.

[SLC_S4]

I'd also say go with AWE or ER sidemounts. I've got AWE and like them.

[ubermidget]

i just switched from rs4's to awe's and the difference is very noticeable.....either awe or er ftw

[ThirdStrike]

i got rs4's and they heat soak like a mf. s aw a ~15degree drop in iat's vs the stock s4's. 75+ deg C vs 55-60 Deg C. better? yes. still the suck..? yes.
id like to try the ER ic's but fuck-a-$1300-ic setup. watermeth ftw

[SlowGolf]

I would like to see somebody run water meth with a dual nozzle set up on the OEM ICs.

[AB18]

Im debating between ER and the ebay front mount. The ER ones are massive, and seem a better all around choice. Simply because there great for road racing, and i would rather not have to deal with overheating issues with prolonged track use.

[Meddie600RR]

Er

[lil' is 300]

ER's or Ebay front mount. ER's perform better and you get the stealth factor. Ebay FMIC is cheap, but you need to hassle with piping that usually looks crappy, you have lots of silicone connections (more area for leak), and you have a big core up front that says "look at me".

ER's are def. the best performing out there, but they are also expensive. But if you were on the fence with ER or AWE...I would def go with ER. I got a brand new set for $1200 which is actually $100 cheaper than AWE.

Jason at amd did wi with stock ic. Saw very good results!!

[ThirdStrike]

Jason at amd did wi with stock ic. Saw very good results!!

iat's were probably in the sub-40's no?
rs4's used usually = ~700/800 bucks
ER's new $1k+
awes new $1k+
water/meth/alc injection usually ~$450
op; get the cheapest used setup you can find. awe er or rs4... then run water injection. OR stick with your stockies and still run water injection. you will see better results with wi period
water meth ftw
/thread

Water/meth no doubt helps a lot, but that's more of a chemical intercooler.

Running 115+ octane and water to cool the IAT's, but like naaawz you'll eventually run out so you will have to be re-filling. You should factor in the cost for a re-tune to get the most out of that set-up...that's usually $500 right off that bat. So if you went with some less expensive IC's like RS4's and added water/meth, it wouldn't surprise me if it actually went beyond the cost of awe or er.

I'm not putting it down, don't get me wrong! Run water/meth with any set-up and it will pwn...especially with good IC's to start with! But I has the potential to get pricey if you're trying to get the most out of it.

i know a whole lot less about tuning cars than majority of ppl in this forum, but i can still bump timing 1 degree, log, bump timing 1 more degree, log, and so on for free :-P
its like running race gas all teh time. the ecu will request more timing just due to the lower iats
i agree tho starting with a good ic setup is better than just water injection

Agreed, you could lemmi some advanced timing without paying top dollar for a re-tune... But if you want to get the very most out of it, then a tune is the route to go (but that gets so f'n expensive....)

[SlowGolf]

I buy 100% Methanol for 3 bucks a gallon and .70 cents a gallon for distilled watter. Rougly $12 for 6 gallons of water meth. I use my washer bottle as so I have a leven sensor in my cluster just like a gas light. 1 gallon of Meth last about 1 tank of gas. So lets just say it costs me $50 to fill up on 91 I pay $52 ro run on a race file daily

[Audi_S4]

hmmm I was just going to buy RS4 SMIC's but now i read this post i'm getting a little paranoid!

is it true what the AWE site says

- RS4 ic's have only 6% more exposed core volume than S4 ic's and AWE has 56% more volume???
- RS4 ic's are a bitch to place and you have to cutout some shit to make them fit and the awe's fit like a glove???
(cause i'm not into shitty fitting, not the most handy guy around...)

hmmm i'm thinking now i can maybe save some more money and buy AWE's or ER's instead of these suckers, it's about 4-500 buck difference but is it really worth the money over the RS4's?

I'm going full stage 3 with pj k04's after the summer, don't wanna buy something i'll regret... i don't track the car, just the usual friday and saturdy night street action...

but if it makes 15-20Hp for the couple of xtra bucks i don't have to think long about it...

help me out here! thanks

[vladbe]

ER's seem to be the best route. Of course all of them will require cutting and fitting whatever you get.

[S4 in_lowplaces]

ER SMIC's

man dont buy the rs4's new. you will pay close to what you'd pay for the aftermarkets.
if you buy rs4's get them from someone selling them on here, then be still dissatisfied with your iat's and get meth :-P

[jaybquick@JHM]

RS4s = poo out here in CA when it gets over 80 degrees. Great ICs but when you have months of heat like I know you do in Sac they just don't cut it.

From the temps I have seen on local cars out here in the valley (an hour south of you), these are the best in order from my first hand experience.

1. - Ebay FMIC core (hence the fact that I am in production on a kit based on this core and use it on my car.)
2. - ER SMICs (have a group buy on these going on as well, should be receiving the next shipment in may)


It mainly depends if you want to keep the fog lights and weather or not you want to fuss with the cutting of the bumper support. If you want fogs get the ERs.

FYI, jason @ JHM told me that all last summer out in cali in 110+ plus days had NO problems with overheating. i have an EFK that he recommends as well so maybe that helps a lot. ive had mine and it was 85 the day i brought it home and of course in some traffic, no issues at all. although its not hot im baking on what jason said.

Well then I guess my original statement about overheating was incorrect. I dont mean to discredit JHM because their intercooler setup defiantly looks cherry and for the price.. [O_O] you cant go wrong.

But since my car is going to see high ambient temps almost all the time.. (good ol South East - Humidity Central) I am personally going to stay with SMIC's and have plenty of surface area for the radiator to cool. Not trying to take anything away from JHM but I have had issues with overheating in other cars and thats just something I would rather not have if I can avoid it.

As far as people wondering why to go with AWE or ER (Evolution Racewerks) over RS4 here is some technical data that can be found on either AWE's website or ER website I just figured it would be nice to have some data in the thread as well.

Here is a comparison of stock vs. rs4 vs. AWE



ER's Data is listed as:

"Features a colossal 360 cubic inches each intercooler for a combine 720 cubic inches. Each intercooler features a high density bar and plate core that is 10"x8"x4.5" in size and has 15 charge rows each."

Its almost an 1.5'' bigger than AWE's SMIC. ER's SMIC has even been used on GT kits and has worked very well. Now the downside to ER's SMIC is two fold: Price, and lack of shrouds. Although many have modified the stock shrouds to fit and work perfectly fine.. Price can be marked down by jumping into group buys for them.. (last one I know of was from JHM a month or two ago)

If your thinking about doing stage III and above I would defiantly recommend going with ER like I said earlier, but AWE isnt bad either.

Lots of information out there just search and take your time.

Cheers

[jaybquick@JHM]

The overheating that occurs from FMICs has never been seen by anyone with an FMIC in street driving that I know of. I personally recommend installing the hi flow VAST EFK to help out. But Dan (Bertworks) even ran his with the stock fan with no issues for longer than me out here in the CA heat.

Overheating with the FMIC is caused from extended (15 minutes plus) road racing in warm temps. You can ask Fred at ER. They are working on an FMIC kit that will aleviate this, but with a new radiator, ducting, etc it won't be cheap. But if it comes from ER it will be very high quality.


But if you want killer sidemounts definitely get the ER SMICs. My GB on them is here if you are not buying immediately. --> http://www.audizine.com/forum/showthread.php?t=190231


Good luck man. Looks like you have plenty of info to make your decision now.

[lrg8683]

i just think having the front mount puts em away from all the heat.

[jaybquick@JHM]

Took these pics of the ERs when I got my last batch, since you had pics of the others I thought I would share.

[Reich]

I just received my er smic and fit well. almost nothing to do. I like them b/c they wont restrick air going to rad, they are only 2'' volume less than fmic, and i think that air will cross more easily thru intercoolers cause there's no interference behind them (condensor and radiator). I only cut about 5/8'' of my original shroud and they fit perfectly. Go Er ftw.

[Audi_S4]

now this is what it comes down to:

Are rs4 ic's worth the 6-700$ bucks ???
or schould i save up for 1200 for awe or ER if i want to go stage 3 witj pj k04's and use the car for streetracing and daily driving???

i just want what's best for my car and for the gains , winning 15hp over the line costs more then 500 extra bucks in the end...

thanks!

[ubermidget]

save up for either the awe's or the er's.....i made the mistake of buying rs4's and now i ended up buying awe's in the long run

[Dowskeet]

Whoa those things are freaking huge!!! I cant get over how big they really are.

Jay have you found out if ER is going to be making any new shrouds to be used with their sidemounts?

The FMIC that your making is defiantly going to be the best bang for the buck and being able to paint the pipes will make it a definite sleeper. If the overheating issues arent there then it would be a function of how much $$ you have and how you want to spend it, and if you want to retain the factory fog lights as well.

Either way you cannot go wrong with the FMIC from JHM (ebay core with custom piping) or ER's (colossal SMIC's)

[jaybquick@JHM]

Jay have you found out if ER is going to be making any new shrouds to be used with their sidemounts?

Yes they are. They are actually finalizing stuff with replication company and may already be in production from last I heard. From the progress I am seeing I think they should have them available this summer.

[Dowskeet]

Would you happen to know what they are going to be made of? I thought I saw a thread earlier that had a picture of the mold they were going to use.

[s4nicetry]

ER's FTW!

what diff did you notice?

is there a noticable diff between stockers and Rs4's cause it seems by reeding this thread RS4's are not much better than stock s4 ones r am i wrong?

[jaybquick@JHM]

RS4s flow way better above 5500 rpm especially on a stage 3 car. But in climates where temps are regularly above 80 degrees f, boost over 21 psi or when road racing they just don't cut it. Especially if you combine some of those. If you are in a colder climate then their flow improvement alone is worth it.

P.S. I got your email and will get back to you shortly. You are about 10 emails back from where I am at, many more behind you though. The ambent temps you mentioned. Were they celcius or fahrenheit??

I got er's pretty amazing cooling when logging iat's
