The "Standard" FMIC he tested utilizes the stock lower IC piping and gained 13 WHP.

 

road, any gear,worse in higher gears

 

i HAVE NEVER SEEN any WHP GAINS with JUST a FMIC although you will have greater defense against heat soak on a hot day for sure. I have seen many a modded Evo and the WHP and their times and traps and the FMIC has nothing to do with gains or losses in a STOCK evo.

 

I agree with all stated above..however please hear me out.. cooler air=denser air=more power.. per given psi.. So 40degree air (would rarely see that cool of a charge) would make more power than 100 degree air.. The biggest benefit to a front mount upgrade I can see is the consistency of power.. Once a smaller core is cycled up and down its charge temp will be higher than that of a larger core which has more heat dissapation area.. On a dyno with fans blowing 70-80 degree air over it you wont notice much.. I have seen the deviced use to measure charge air in and out of an intercooler.. Here is where you would notice if a intercooler is helping or not.. It would likely help a little if you are maxing out the stock turbo (upper 300-400whp) I dont think it would make so much of a difference on a 250-350whp car such as mine.. I am doing the pipe and intercooler as so I dont have to worry in the future..
I run an injen intake which draws in air from the inside of the engine bay.. it works well and has a nice upper pipe.. hard to beat the price.. however if you must have the coolest air possible then go with the cold air setup.. However you have a 7 with the nice hood vent which would feed most any intake fairly cool air at speed.. ambient underhood temps drop while the car is in motion... Most of us dont care how much power our cars make sitting still..


P.S good to hear from foreign evo owners on here.. good luck in your quest for more power!

 

STock Turbo Flows 550CFM's Max.

Stock FMIC handles over 600CFM's It is fine and money is better spent on cams for power

 

why would an intercooler help with a drag race? you sit there in the staging lines killing your intercooler most of the time... that's why air to water intercoolers exist... so your claim that an intercooler isn't gonna gain power is erroneous.

all you ahve to do is look at myevostore's test results from gt40 swapping his avo intercooler out and nisei intercooler in. there is obvious temp change and therefore obvious power change.

i'll concede that buschur once said that he could keep adding larger and larger intercoolers but not gain any more trap speed but that's also because at some point... the air speed that is traveling through your intercooler is not gonna net you any more cooling. intercoolers should help even in drag races... but also... all intercoolers on the market besides the nisei, br, arc, and greddy rspec are pretty much crap...


dude... a straight pipe will flow MORE than 1000 cfm if you put the right compressor on it... does that mean it's gonna get you more power? no.

there is no measure of intercooler efficiency, there's no hp rating for intercoolers, that's all bs, a figure that doesn't mean ANYTHINg. the ONLY way you can tell how efficient an intercooler is is by testing temperature differentials under similar cirumstances on the ROAD where it really matters.

exactly what rob has done with the nisei and greddy v spec (which is a piece).

 

and intercooler is more of a 'foundation mod' IMHO

 

Sorry, there is ,and CFM flkow is a BIG part of it. add a larger turbo to the Stock IC and you will begin to see more heat soak and more pressure loss. IC's are certainly rated at WHP and flow, that's how they work.

Again adding a FMIC will gain you no real WHP on a STOCK trubo evo, but it will help prevent losing it on hot and humid days. If anything a LARGER IC may hurt as teh stock turbo will have a hell of a time properly pressureizing it, cause a little more lag and pressure drop.[

 

How do you explain Bushur's gain of 13 WHP with his upgraded intercooler and stock pipes?

 

I don't believe it, it doesn't

I have YET to see ANY WHP Gains from a FMIC Only mod on a stock Turbo. You would make 13WHP with an upgraded Lower IC pipe, send me the link to a FMIC ONLY mod gaining that, thanks.

 

I dynoed 10More WHP and a better torque curve with JUST A FMIC. oh the bumper was off if that matterS?

 

I have yet to see any significant or repeatable gains from a FMIC. I have also seen a 11.8 @117 on pump gas and a stock FMIC. Dont get me wrong it is a great piece to upgrade too but IMHO is not needed until an upgraded turbo

 

See below, his "Standard" Intercooler , which he tested below with a 13WHP gain retains the stock lower IC piping:

"Yet more testing that we did.

Last I left off at our Stage 2 kit. 320 hp and 329 ft lbs.

I wasn't in a hurry to do cams as when I get to that portion of our upgrades I want to test the 264/264, the 264/272, the 272/264, the 272/272 then some racing cams I have. So the cam testing is going to be pretty involved and take quite some time. I am going to do this testing with the EMS on the car and speed density so I can log and watch what is going on.

Anyway, not being in a hurry to do cams I figured I would throw our standard FMIC upgrade on the car to see what would happen. Now, it is cold as hell in Ohio right now and the gains from any intercooler upgrade I would think will be lower in this weather than on a hot summer day. As a matter of fact these dyno pulls were done with less than 15 minutes between any of them. Most were done with two back-to-back, then as quick as we could make a change and go again for atleast two again. So the car has been abused to say the least. Right now I am on the 209th dyno pull on my new RS. (poor car got the wrong owner!!)

The front end of my car is off as it makes it easier to swap FMIC's and get to the engine bay, the FMIC swap took all of 15 minutes (probably not that long) with the fascia off the car already. This kit uses the stock plumbing in and out or in our case uses our upper i/c pipe kit. The standard kit that we did this test with is exactly the same size and tank design as our deluxe kit, just doesn't use the shorter lower i/c pipe.

First pull I noticed the boost was a good 2 psi higher than before. I had to turn it down just a little. Power went up, 333.5 hp and 339.1 ft lbs. Really pleased with this, that is a 13 hp increase and 10 ft lbs."

"That is correct fixem2. I don't want to advertise that the power gain between the two FMIC kits are different. They dyno showed a slight increase between the two and I just don't personally believe that the lower pipe is worth 6 whp."

riddle me this then.... why is an improved intercooler necessary on a larger turbo when the larger turbo makes the same power more efficiently (less heated air) whereas on the stock turbo... pushing the limits of the stock turbo produces MUCH hotter air.

sounds like you need an intercooler for a high strung stock turbo and that it's less necessary on an big turbo car... of course that is taking into consideration taht everything else is the same.

the real reason you need bigger intercooler on a bigger turbo is not because of heat (at least not firstly) but that you want to get rid of flow restriction. so your cfm arguement is right here... the hp will not be capped by the flow restrictions of the intercooler hence a higher hp rating. but my arguement still stands... the cfm rating says absolutely nothing about the cooling efficiency of the intercooler. can you rebuke my straight pipe flows 1000 hp arguement? cuz according to your philosophy that's the best intercooler of all.

 

When I did a quick test on the spearco drop in fmic "upgrade" with a pretty high strung stock turbo (11.9 @ 114) on racegas with stock cams, I came to the conclusion that the larger fmic was not as cooling efficient as the stock fmic. The less restricitve, higher flowing intercooler did not seem to yeald any real world gains on the track due to the lower pressure drop and higher flow core.

my opinion is that for the stock turbo, cooling efficiency is more important that pressure drop.

for a big turbo, pressure drop is more important.
