most of my stuff I DIY ..I don't believe in spending money on good from the 'vendors' like you .. so YOU GOT TO STOP LISTENING TO VENDORS AND WHAT THEY ARE TRYING TO SELL YOU. 1st of all I DON'T NEED RACE GAS to touch 28psi because thats what I run on pump gas DAILY .. and before you shoot your mouth off AGAIN my pump here is 100octane AND OCTANE DOES NOT PREVENT DETONATION POSSIBILITIES ON A MODIFIED ENGINE WITH STOCK TURBO.. gosh .. lets SEE WHAT OTHER RUBBISH YOU wrote


See who's quoting vendors ??? you gotta listen to yourself someday ..
you are arguing something you don't understand .. I think I know why now .. hmm .. must be the d!ck growing out from your forehead .. cuz the ***** are covering your eyes and preventing you from seeing clearly ..

good day d!ckhead .. continue to live in your own fantasy world .. I'm done with this thread ..

Trinydex thanks for the correction ..

 

The whole deal with intercoolers is balancing airflow and pressure drop with cooling efficiency.

The more airflow (CFM) the turbocharger makes, the large volume of intercooler is needed to flow that larger CFM of airflow with the same pressure drop accross the core. Pressure drop increases accross a given path of travel with increasing airflow.

cooling effiecency is dependant on the frontal area of the core that has ambient air flow, the design of the internal passages and fin density. Smaller internal passages cool better becuase of more surface area and slower air velocity inside, but have a higher pressure drop. Large passages flow air easier, but don't cool as well.

IC core thickness is also an issue with cooling efficiency, and is the major factor IMHO with the spearco core and most "upgrade" ic for the evo vs the stock fmic. The stock IC is thinner, and the front face that gets ambient airflow does the majority of the cooling. The back fact of the Ic that's next to your radiator does little cooling.

The stock ic is simply not restrictive enough to cause a big pressure drop with the CFM the stock turbocharger can push out. The cooling efficiency of the stock IC is probobly BETTER than most of the upgraded fmic, but is slightly more restricive to airflow (higher pressure drop at XXX CFM).

With the stock IC and stock turbo...are a good match. If you go to a bigger/thicker core and lessen the pressure drop (becuase the upgrade fmic flows more) but lose some cooling efficiency (because the upgrade fmic is thicker and has larger internal passages)...you gain very little. That seems to be the case here.

 

only one small detail... smaller passages flow faster (more velocity), like big straw going to little straw, but it's tru that the turbulance from finning is then more violent. just a very minor detail.

larger intercoolers can also cause more pressure drop due to increased volume that needs to be filled... but thena gain that all depends heavily on design parameters. if you fill up the internal volume with fins then of course there's less volume for the air to have to fill.

all subtleties. but that's a clean explanation right there.

the stock core probably isn't that restrictive, but there are less restrictive cores out there. the stock core can also be improved upon in the heat sink mass area as it could heat soak easily. this is of course only a concern to roadracers... sustained high rpm at race tracks which are usually in the middle of a desert requires more careful heat management. which is why i even make a deal out of all this at all. socal racetracks get hot in summer.

 

Sorry dude, you just open your mouth to hear yourself speak You have no idea what you speak of, you rather look good and be wrong, then be right and look bad. Your arguing whatever a vendor told you and trying to defend your purchase, get over it.



Missed the point again, IDK WHY I bother with you . If you have a HUGE IC and a smaller turbo, your gona get pressure drop, end of story I never even said anything like that besides that any proper IC is going to give you some pressure drop, it has too, even teh best out there offer a 1PSI or less drop.


hehehehehe Your getting so mad , and your so wrong, this is hilarious, keep it up, gives me something to do. BTW if I could suck my own dick I wouldn't have ANY time to do anything else, just be lucky that I can't.


Running a huge IC and a smaller turbo, you get pressure drop and inhibited throttle response. You have to match parts properly. Sorry.....


You’re an idiot , you are so dense IDK WHY I bother talking to you. Probably for a good laugh. Why keep arguing that stupid pipe and CFM example? An IC flows CFM’s, it needs too, it also has to cool it as it does so, A pipe has nothing to do with it and in NO way is it related to an IC, if you have an IC that isn’t designed to flow a large turbo, it’ll heat soak and pressure drop and not cool properly. What is not to understand? You can’t be this dumb, I hope that this is a big joke, is it ?



End tank has a LOT to do with, but you knew that right, cuz your so smart ? END TANKS MAKE or BREAK the whole design, deal with it skippy your outa your league .


JESUS CHRIST man you just constantly prove at how stupid you are , I swear this has to be a joke. Where is the man behind the curtains pulling the levers to your stupid mouth???? The stock IC is WONDERFUL and is perfectly matched to the 16G turbo. It may be hot, all turbos are idiot, like any other turbo is going to be ice cold. Anything past 7PSI is gona need to be cooled. BUT the stock turbo doesn’t flow enough to overwhelm the stock IC, remember I told you about VOLUME, see VOLUME is the key, PLEASE, PLEASE try to understand this, once you do, it’ll work out for the best.

I am sorry, I think you have me confused with someone who CARES what you have to say, not me sweetheart, go tell someone else your life story. Look at how testy you are, man i got you so mad I bet you are dripping in your panties Race gas prevenst detonation, sorry sweetheart, you should shutup now. Pump gas is 93 or lower, some places have 94, and that what pump is assumed to be. Hell I can run it too but at $550 a gallon no way.


WHOOP, someone has sand in his vagina , better have your boyfriend lick it out before you get on the internet and type, you’ll be less irratble and so will your posts. $10 says your back with your Boy friend typing up a storm


See, this is what I am talking about, deal with it kiddies.

 

umiami80 pissing someone off again,that's a new one

 

Yeah I tend to do that, my personality is VERY abrasive. sorry

 

You aren't sorry LMAO

 

Kindly adjust your personality to match our forum rules concerning name calling. Your "thoughtful" response will be deleted if you don't clean up your comments. Thanks.

who said anything about running a huge ic with a small turbo?

why are there intercoolers that increase response and boost pressure over stock?

the only reason you agree with dsmotorsports is because he agrees with you about the stock intercooler... and that's fine, just recognize it as taht because i agree wtih him for the truth reasons.

i agree.. the stock is better than most aftermarket ones.. but it is a little more restrictive... so what does that mean... you have to revise the finning to make it less restrictive but still maintain the cooling efficiency. already said this before.

i don't understand how you spin up so much more bull**** that is not related while you're trying to "counter" what i or anyone else says... you're practically arguing with yourself and i'm just tryinna sort out the **** that i never even said.

and once again... i didn't buy anything... haven't touched my stock intercooler.

any turbo is gonna be hot... but a bigger turbo will not be AS hot. that's the whole point... no one said any turbo is cold... once again... spinning stuff outta the air that has nothing to do with anything to TRY and make me look dumb. so check it out rumplestilskin, what have you said about cooling? tell me what have you said about cooling? cuz if you're right... and all you gotta do is look at VOLUME the striaght pipe has all the volume flow capabilities that you desire. i keep reverting back to this cuz i think ti's a simple engouh example for you to udnerstand... but you don't get it still.

cooling.. tell me all you know about cooling... please. cuz that's what i corrected you about in the first place. cfm and "hp ratings" say nothing about how cold the air is.

 

I think they do so with upgraded IC pipes, that helps ALOT. I don't see how adding a larger IC could improve throttle response alone. The stock turbo can barley fill the stock FMIC let alone one that is thicker and longer and so on. I doubt it does produce a response alone, unless of course it allows more air to travel faster but then their goes your cooling properties and of course your boost will taper to lower levels faster. The Stock IC is money it really is and is well engineerd piece. It is hard to find quality parts for the Evo as most of the car is high quality.



Actually I think it is funny people get so worked up over somthing stupid and pointless. I love to push buttons and watch people dance and sing their song and hear their generic rant, lets people get out some steam and is quite funny. Gives me something to do.



?????? What I sleep for 20 years ? IDK what that means, woulda been funny if you said Rumpledforeskin, now THAT is funny .


I Don't think you give the stock IC enough credit. Some of the fastest Stock Turbo'd Evo's run them, and they are fine, they work perfectly with the stock turbo, hell look at the FQ400, that amazing machine uses the stock IC on an upgraded turbo far larger then the stocker, I wonder why those stupid mitsu techs would do that .



OH I get what your saying, it's just stupid is all on how you compair a straight pipe to an IC. Please don't try to come off as an expert, you don't make IC's dont even have one on your car, all you know is what other vendors/people have told you CFM's is How an IC is rated, curious? I mean you can have a VERY VERY efficient IC but if it is flow rated to 500CFM's well if you run a turbo that flows more then that, it'll back up and get hotter if not then heat soak and pressure drop. The stock IC offers a restriction, it has too, that's how it cools, if there was no restriction, welp there would e no cooling. ALL ic's have to offer some sort of restriction The Stock IC cools VERY well and I bet you could use larger turbos on it, although not make the best power it would't kill you.


Don't get me wrong, if I had the choice I would rather have a bigger FMIC for looks alone plus I plan on getting a bigger turbo soon so it is a must. But right now the car does not need it and would not benefit from it.


For you guys with stock IC and piping, get a lower IC pipe replacement, I guarantee results over a whole FMIC, unless you get the buschur with the intigrated lower IC, they you get both.


I like AMS stuff because it always fits so well, like OEM for the car and I know it works well.

 

there are intercoolers that have just been slapped on with stock pipes that increase throttle and boost response.

stock turbo has trouble filling stock intercooler because the stock intercooler is restrictive (the internal finning is louvred, hence its decent cooling capabilities).

never said that the stock intercooler doesn't work, it does. but there is better, the point all along. if it's about replacing the stock intercooler with a poor typical unit... i definitely agree... keep the stocker.

i never said that cfm and hp rating isn't good for something. i said it's not good for telling you how cool the air comes out. temp tests are the only way of figurin' that out and in this time when every intercooler has the capacity to flow so much hp of air the deciding factor is the temp drop.. not how much air the ic can flow.

hey... i won't argue wtih ams's quality, never looks anything but top notch. i just have beef with their end tanks.

and lastly... vendors told me very little about intercoolers. aside from buschur no one has ever told me what type of finning they use. why? mostly cuz they don't even freakin' know. i had to find pictures of each type of core and figure out the details myself. i don't sell intercoolers and i haven't bought one yet... but i know which one i will buy when the time comes. all about the research.

 

Wow another life story, hit every point didn't we? The Stock IC is NOT restrictive on the stock turbo, if it was people would notice more power when bolted on, there isn't any. I also say you will feel a lower IC pipe more then any fmic, do you even have any of these mods done to your car, or are you just saying what you heard? Stock turbo has no trouble filling the stock IC, none. They are matched very well and work perfectly together. TH epiping is garbash and I wonder why mistu did this.

I still stand by my statement that you dont need a new FMIC until a turbo, IC piping for sure, should be in teh 1st line of mods.

 

do you have every mod ever mentioned on your car? i speak of what i know... for intercoolers most of what i know came from

http://www.are.com.au/techtalk/intecoolersMR.htm#ENGINE%20DESTRUCTION%20%20!%20!% 20!%20

some australian company not afraid to tell the truth. lots of good info with lots of pictures and diagrams.

i've seen the intercooler that i spoke of in action. also br of course has his intercooler on his stock turbo rs and has gains, he also saw gains from both the standard and the deluxe.

what is "worth it" is entirely subjective. i'm all about the ultimate ultimate which is why i choose to speak up.

 

umiami80s theory makes more sense to me than trinydex .
peace to yall
