Corksport FMIC w/ Ram air Review

[MS309]

I'll just cut to the chase and give you my impressions of this kit, haven't seen many people talk about it.

The good: FMIC works at bringing bats down quickly. Install is not too bad, everything fits and lines up.

The bad: Not sure about the ram air intake, Stock shifter weight bangs against hot pipe.

Lets start with the bad. I had to take the stock shifter weight out because it wouldn't let me engage completely in forward gears. only two solutions for it, no weight or shorter weight, I just went with what I could do to fix the issue at hand, no weight. It shifts just fine without it, a bit notchy but I like it.

I don't know what to think of the ram air kit. It looks cool, but does it really work I don't know. I wasan't too happy with how the filter was seated, it left a brief opening towards the front and back, not compltely sealing the box. I should also mention that this was a used kit, so I'm not sure if this is how the filter comes from CS new. You are supposed to use the stock IC shroud to make it seal I assume but the shroud is a tough fit. Even after all the trimming, It was very hard to shut the hood, I had to force it shut, just didn't seem normal to me. As for performance, I noticed a slight lag in throttle response, my trims were off quite a bit (+7/+10 at idle and cruise) and also, the CS maf housing is a smaller diameter compared to the Sure maf housing.

EDIT: See post #19 , its all fixed and runs pretty well.

I wanted to see if there was any difference running the sure intake instead and yes there was, throttle response was much better and I dont' have to worry about water/snow/bugs getting inside the intake. Regarding this intake setup (see attached pic), it only works because the CS inlet houses the crank vent hose, which allowed me to directly bolt the maf housing to inlet pipe.

The FM core itself works well, it drops bats much faster than the stock unit could, so no complaints there. I did experience some pressure drop, about 2 psi I believe. Today was a hot day (about 85) and the car felt consistent every time I stepped on it, no boost leaks yet either.

Here are some logs for comparision, the one's with this kit are labelled with FMIC, the v1.5 one's are with stock IC during my tuning process.

only have one log with the ram air system which I took late at night (datalog 4), the increased g/s flow could be due to the really low temps or maybe its the ram air kit, I don't know, but It's not a significant difference. I switched back to the sure intake today, so datalog# 7/8/9 are all with SU intake.

datalog 24 would compare with datalog 7 in terms of bat's and how they fare stock ic vs fmic (similar outside temps/bats).

datalog 8 is just random stop/go driving (outside temp around 84ish)

datalog 9 is what I took later this evening with outside temps being around 68ish.

Lex I believe I can run more timing now and still have some room to increase WG to achieve the same boost targets as before ?

Feel free to post up comments/questions.

some more pics, The Core was painted black by previous owner, so can't really even notice its there.

It's interesting that the ram air box doesn't seem to be sitting straight. You want the seal on the hood to seal against the plastic just as it does with the OEM IC for the best effect.

You did gain some flow (g/s) while boost dropped which means the VE of the motor has increased with the kit. This is good because less boost pressure = less heat = less knock. The BATs are quite low so I think it will take more timing as well. We can probably tweak the map for a few more ponies whenever you're ready.

In terms of the shifter weight, a few manufacturers make smaller ones - COBB does for sure for their FMIC kits.

Great review!

[Instrument_Guy]

Can't wait to check this out! I think the Sure filter set-up that you hooked up is better than the top-mount Corksport filter; that thing looks a little hokey. Time for a DP

I've got a small Sure counterweight in a box somewhere; we can see if it fits around the IC piping

[Ray Danger 2020]

I like the way you have the SURE SRI in there. I think it's much more asthetically pleasing than the ram air system. I'd definately run it that way if I could.

[Lex]

Hold on a sec ... you're not running the RAM air intake? That is the best part of the kit IMO because it really increases pressure pre-turbo. Give me a shout, perhaps the MAF cal was the issue because I think that the RAM air will make a positive difference (given the filter fits properly).

[outshined]

So...does one simply just stay home when it's raining?

I'm trying to understand how the "ram-air" filter's open exposure to the elements is a remotely good idea outside of dedicated dry-weather track duty.

[Bob-o]

The plastic shroud "seals" the filter to the intake so it holds out water.
Lex, the issue we had with the ram air is that the filter seemed to flex and bend too easily to sit on the intake box properly. We concluded this because once he put the sure intake on, we gained some, but not all the boost he has pre-fmic install.

Also, the plastic shroud did not fit well on his car for some reason with the ram air. Could be installer error, I'm not sure.

The MAF Cal was likely messing with the load targets. Also less boost is not always a downside. You have to calibrate the MAF and compare airflow, not boost.

Lex I'm away for holidays starting next week, when I'm back in September we can retune and compare both setups.

But the issue would still remain with that filter, I'll contact CS and see what they say or fab up some way of my own to seal it properly.

Also, with the current intake setup, there are less bends, only one at the inlet and the rest is straight to filter, I recall you saying somewhere less bends equals better VE ?

Hmm I wanna see the ram air setup dialed in and dailied. I almost got this kit a while back but shit happened and I had to stop it. Lex convince him to go ram air again lol.

[Standsideways]

Sure less bends= more VE..thats common sense.

But that big ram air box with the scoop likely blows the SRI out of the water.

Get the maf cal and tune on that ram air box going OP

[MS309]

I'm trying to get a PN for the filter via CS, its just a k/n pre oiled one, fix up the maf cal and give it another shot.

If it is just a generic K&N filter, give JB Automotive a shout when you get the PN; they carry a lot of K&N's @ their west end store

PN: 33-2319 in case anyone else needs it. its $70 @ partsource/JB's and has to be ordered since no one has it in stock. So I'm just going to improvise and ductape seal the current filter around the box, trim the shroud by the intake pipe a little and make this work. Its raining all day today so lets see what happens.

forgot to mention earlier, the small under tray towards the front of the bumper doesn't fit anymore due to the fmic core, the core clears it just fine but there are numerous tabs sticking out from the plate that can't fit due to the core, just an FYI not a big deal.

[Raider]

I had issues with my stock weight and CPE CAI. Cut the weight down. Lighter is better.

so you guys are gona love this. I sealed up the intake to the box, adjusted the intake piping a little and made the shroud fit better this time, it's still a little raised up on the right side, but I believe that's because of how the piping is coming out of the box, also I can't tighten that right side any more since the bolt eventually touches the ram air box. anyway, it seals pretty damn good, hood closes just fine with a little force.

also adjusted my maf values, drove around a little to let the trims settle and took this log. Car does indeed drive better with the proper seal, and it does pull harder up top. max g/s was 260, looks like I gained a good 15-20 g/s over a traditional SRI setup; boost and load are also up. so Thank you all for making me give this another shot, it does work and it works very well, I didn't know it would actually make a difference. !! Brydon@CorkSport

someone plot this on VD !

EDIT: wanted to also mention, after getting home I looked at the filter again and what I noticed was that due to air flow the fins at the front itself get pushed backwards, which would explain why it looses its seal eventually, the tape I used is still intact so there are no gaps between the filter and box. And I also drove around in heavy rain today, water doesn't get in there at all

[dantes5823]

Very nice. Glad rain doesn't get in there. How's the turbo sound?

Quite. No more whoosh or psshh. I just hear more of tranny and engine noise from the mounts now.

Oh that sucks. No more ricer noises for you lol. I know the feeling. Stupid gtx. But I haz ewg to keep me happy lol.

[JDW1]

I've always liked this set up but from what I've heard having the ram air kit for some one like me in a hot climate it would cause higher IAT's making it harder to get the BAT's down. More g/s at speed yes but the main purpose of getting a FMIC would be lower BAT's.

Have you noticed any think of the sort? I see your BAT's look pretty low.

Haven't noticed anything of the sort yet since I just put this on recently, but after driving around during the day I checked the filter and ram air box, it was normal temp, cooler than the rest of engine bay.

I can take a small log just driving around the city, that should give a good idea of what's happening.

How do you figure? Ambient temps from outside<Underhood Air temps

[JDW1]

I've seen logs posted (granted from a warmer climate) where BAT's weren't as low as hoped and the IAT readings were way above ambient. The IC can only drop the temps so much lower than the air temp coming in. It made sense seeing how the ram air kit is sitting right on top of the engine. Kind of like how you see a little lower IAT's with a CAI vs SRI.

Lol I need less noise, it's all racecar sounds on the inside already with shit rattling everywhere.

I'm excited to see how much more timing can be run now.

MS309 I'm doing the same setup. I really like the idea of having air go through the hood scoop to feed the intake. Today I ran into a problem. Don't ask me how but the rubber part under the hood scoop when you open the hood ripped off my car. I think the main purpose of this part was to feed the TMIC as much air as possible.

Will this effect the Ram intake? I will still have the shroud on top of it. I'm thinking with the intake sucking in air it shouldn't really effect anything but I wanted to be sure! Especially with the potential water issue. I have an E-mail to Corksport asking as well but figured I ask here as well.

Thanks bud.

can you post a pic of where it ripped off from ? I'm thinking maybe you can just buy weather strips of similar thickness and glue em on top where the rubber ripped off. I think having that tight seal is cruicial to this intake's function, I ran it without the shroud (i.e no seal) and it didn't have the same effect.

Regarding the water issue, from what I noticed water doesn't really get in that far, also do what I did and seal the filter around the box before putting on the shroud.

[CorkSport]

We sell the panel filters for $63 if someone needs a replacement. Being in Canada I would check locally like you did to see if it is cheaper than having one shipped to you.

We have tested out the ram air setup by running the car through a car wash and driving the setup in the rainiest days we have here in the North West. Unless you submerge your car you should have no problems with water. The water that gets to the filter gets evaporated by the passing air and pulled through the engine as water vapor.

Wafer injection! Not that you would need it when it is raining,lol.

I will definitely post some pics. Can't now but will tomorrow. If you open the hood it is the rubber square thing underneath the hood scoop on the inside. It got caught on the RAM filter because I'm an idiot and didn't put the shroud on. When I tried to open it this morning I felt it get caught and forced it up (again I'm a dickhead)

I think it was just to force more air into the stock TMIC. With the Ram intake acutally sucking in air I'm sure it will be fine.

That is a bummer. Is the seal in good enough shape to re-install?

[Floridaspeed]

I don't think so. Mostly all of the holes ripped on it. I could probably glue it up there lol. Would you highly recommend getting a new piece?

[Lex]

Did you rescale the entire MAF? The gen2 is a little harder to draw direct g/s comparisons to since at WOT it DOES adjust to hit WOT AFR targets unlike the gen1.

When you're ready for a top-up I will take a closer look at the numbers but I was expecting you to see higher g/s flow.

[CorkSport]

I would see if anyone has a used seal to buy here on the forum.

If you're slick, you may be able to fab up your own with some garage door weatherstripping./

Yes I did rescale the entire MAF.
