FMIC Stage 3- VS Stock Intercoolers, Come Check!

[AudiSportB5S4]

OKAY so once again here's STOCK intercoolers on a dyno, EPL Mustang it was 59* in the building when it took place. this was the SECOND pull on the dyno



awessommee up top just pulling in that abundant warm air!

NOW this is tonight, it was 63* out, and this was the 3rd Pull, prior to two full 3rd gear pulls....



Look at that !!! Just FLATLINES basically, sorry for the terrible shot of excel i coundt get a good chart. I was very impressed, you can feel the power up top much more with that cooler air very much so. I mean, i know everyone knows the FMIC's work, i just wanted to compare it for ppl!

PS, granted i did not go ALL the way up to redline but i think you get the idea, on the way home i did it again for shits and giggles but lost the dam log somehow, and it actually stayed at 24* Celsius the whole time and rose to about 25-26 at times. So prettayy impressive.

28 Celsius = 82.4* F, highest temp recorded on that one

Not quite scientific data, but congrats

(do a few more logs, curious to see the graph to redline)

[AudiSportB5S4]

lol, im tryin'! How the EF can I graph it, i hate office 2007, they shouldnt of touched the old one. idiots. i ll re-do it tomorrow with it all the way to redline. and just repost it in here.. thanks for the advice =]

[Cactus00S4]

well i dont have any data like that, but i dynoed my car with stage3-, stock intercoolers, and piggies with vm3 exhaust, then dynoed it with all of the above but with test pipes and fmic and i gained 50whp, both runs were on the same exact dyno

Excel 2003 ftw

I hate all the 2007 crap...so confusing.

its cause they use ribbons instead of files lol its weird but once u get it its mad easy... hey man congrats, your jackets say congrats as well lol

[Matt@JHM]

Much better.

FMIC FTW

It's interesting, but to produce a bit of an arguement. I don't think you can really compare air to air intercoolers on a dyno. Yes your taking a big ass fan and blowing it towards the intercoolers but catch what I mean...

The use of an intercooler is taking the outdoor elements and getting the most out of it for cooling.

I think the ol' FATS runs would make much more sense. 3rd gear pull from 4200-6500rpm on the open road and data log.

Are these the ebay FMIC?

Yeah, I see what you mean for sure. Unfortunately I dont have them anymore so I cant do that lol. To answer your question though YES the CXRacing (eBay) intercooler.

Currently, my OEM SMICs are leaving me at 119-120F after a 2400-6200rpm 3rd gear pull on a 70F day.

This is also at 22Psi of boost.

I'm kind of surprised that my peak IATs are the same as Mike's Stage 3- IATs. I figured that mine would be higher.

Why would your IAT's be higher than mikes if you are both using the stock side mount intercoolers?

Even though mike is stage 3- (bigger turbos, etc) without a bigger intercooler your still having the same cooling properties as you would on stock turbos.. It wouldnt matter how much air is being pushed through the system if the part of the system that is cooling the air is the same wouldnt that result in the same IAT's?

Please if I am wrong someone correct me. Just seems logical to me..

An intercooler can only cool so much air at one time and only remove so much heat from it due to the surface area. By flowing more air, I would expect the IAT number to be higher than at a lower boost (lower boost is lower MAF readings and thus less actual charge air).

The temperature is going up because the surface that the air is touching can only draw so much heat at one time. At this point, more air is flowing over these surfaces than the surfaces can efficiently cool. Therefore, the air's temp doesn't drop as much by the time it passes out the IC's outlet. Smaller cooling delta.

So my point is that more airflow will result in less cooling. We can already see this because a chipped car will flow far less air than Stage 3 car.

Another variable here is compressor efficiency, obviously as you depart from the center of the efficiency island, your compressor's outlet temps will really begin to climb.

Gotcha

I just figured that since the stock intercoolers were meant for stock boost and not for 20+ they would only efficiency cool the stock amount of boost. Before high IAT's are inevitable. Having the rest of the air basically be "wasted". (not being able to be efficiently cooled since there isnt enough surface area to properly cool X amount of air being pushed through the system over stock levels).

So even if your going to push the boost up with larger turbos or a chip there wouldnt be a way for the stock intercoolers to cool that amount of air over stock levels resulting is almost the same IAT's.

You kinda suck at logging. ;) Do a full 3rd gear WOT pull to *at least* to 6700 RPMs. Even your stock ICs didn't move much down low.

I'm getting my ERs put in my Stage 3- on Saturday, I still got the stocker ICs in there. I will do logs between both. Glad to hear your FMIC is working out for you!
