Install help please for an EVOMS Intake

So i took a shot at putting in the intake today, it looked pretty straight forward, and the car seems to run without a hitch, but i'm conscerned by two things: 1) the back part of the triangular box is SUPER close to the compressor pulley...like less than a finger gap. 2) the triangular intake, i'm not sure if it is sealing properly with the hard piper since there is no clamp thingy to hold it tight. Can someone please post install directions (i got mine used off another rennlister so i have none), and/or some photos of their install. My car is a 3.4L. Thanks in advance. Regards, Your friendly neighborhood mod-guy.

Omar, EVOMS has directions on their website that you can download. I'm happy to take some pictures of mine, but yours sounds fine. It does sit very close to the pulley. As long as you have the L-shaped bracket next to the engine cover latch, it will be fine. The triangular part of the intake, I believe, is just to keep hot air from the engine compartment from going into the "cold air" induction. I will be glad to take pictures if you need them. Mark

thanks mark. i'll post up my photos in a bit. i removed some of the spaces from the L bracket that connects 2 the mount point to move it away further a bit from the thingy. will double check the install instructions on evoms website. also..mine was originally for a 3.6L but i was told that they are identical, you just need 2 not use the larger supplied bracket.

mark, i checked evoms's website, the 997 install seems 2 be a bit different in that there is no mention of the larger supplied bracket. anyhow..here's some pics of the gap between my pulley and box. if you could post some up of yours, that would be awsome.

Omar, here are some pictures of mine. You can see that the pulley rubbed on mine. I bought it used from a guy that had it on a 997. The only difference according to EVOMS is the bracket. I didn't get the mounting bracket for a while when I had it on my previous 996. I have about 1/2-1/3 inch of clearance between the pulley and the CAI housing. Don't you just love the sound yours makes near redline???

i havn't taken it to WOT yet because i was scared of mangling something horribly thanks for the pics, much appreciated. honestly, i'm not really impressed with the kit considering the price. glad i got mine used. Sorry evoms, normally your stuff is quite good, but this intake is meh in terms of quality at best (the sound is AMAZING tho...so does it even out )

i've highlighted some arrows: arrow 1: my kit didn't have this since i got it used, no worries, 20 cent piece. how did you get that thing on tho..did you attach the filter and the metal pipe outside of the car, then slip everything in as a unit? because the whole filter doesn't stick out of the whole in the triangular intake, it looks like it would be an impossible task to do so otherwise. arrow 2: christ on a bike, i can't believe how close the pulley on the denso compressor gets to the triangular box, yours actually ground away on it eh, that's crazy.

I had mine installed at sharkwerks, and it's been rubbing on the pulley. Alex, the shop owner, said it's no concern since it's just plastic. Worried at first, but i guess it doesn't matter. sorry to pics to offer.

hey bud i'm not a technical guy but do me a favor and as soon as it's all set.... windows up.... hwy....... drop it into 3rd..... and punch the throttle to redline. that howl at the upper reaches of the rev band is... intoxicating with the evoms unit.

+ 11,000,000,000 my buddy put the EVOMS on his C4S and it sounds MEAN.

Its just a bit disappointing tho, especially if you do end up grinding a hole into the side of the intake, your going to be just letting in more hot air, negating the "cold air intake" effects.

I think it's missing circular clamp that goes on the outside of the trangular box....IIRC, there is a clamp inside that holds the triangular filter to the tube, then there's one that fits on the outside of the box right under the hole between the triangular box and the tube. I remember that mine didnt' have the second one and it kept coming apart. Look at DeadEye's arrow pointing to #1...that should be the second clamp.

had anyone actually LOST power with this intake? i don't mind too much that it doesn't make any, but has anyone actually lost power from it?

dead, do u actually think someone's going to actually take the time and expense to do back-to-back dynos let alone since dynos can't ever recreate the air ram effect at speed, u think someone actually has access to the wind tunnel to really get at the right data? indirectly i'm saying just enjoy the sound and whatever perceived power it givesu . whether it gained or lost your **** can't tell.

seems about rite. does anyone else get a sort of Chuffing noise when you go hard on the gas (WOT)? i get a chuffing noise from the intake when i step on it (it just happens for a split second then goes away). doesn't happen at half throttle.

Omar, the sound you hear is the throttle butterfly opening & sucking massive quantities of air. I assembled mine outside the car and then installed. Mine only rubbed on the pulley because I drove it for a while on my other 996 with the L-shaped bracket missing. I will not rub the way it is currently installed. The more you drive it, the more you will enjoy the sound. When I returned my previous 996 to stock, before selling it, I was disappointed every time I drove it without the sound of the CAI and exhaust.

i get a chuffing noise when i'm getting off the gas

I don't get anything from mine that I would describe as chuffing, FWIW. My EVOMS intake is pretty much undetectable at lower to mid-band rpms. I'm aware of it really only at WOT, when it produces this fantastic howl that's quite inspiring from inside the car, and seems to turn heads from outside. Power wise, it's hard to say what it does. The seat of my pants says there's some extra grunt in a narrow, narrow range right at the top of the power band, which is what you'd expect from something that basically just lets more air in. Nothing anywhere else. I'm looking forward to seeing what an ECU flash will do for intake/exhaust package I've got. My guy is now recommending REVO over GIAC... should be fun. For me, the intake and exhaust mods were really about being more connected to the car. I don't care about a few HP one way or the other. Not really a bench racer. What I cared about when I added the SSK, intake and exhaust was putting a little bit of sports car edge back into the ride, just so I could feel what the car was up to. I'm sure I will be roundly mocked for this, but the truth is that I wanted the liveability of a 996, with SOME of the edge of the 993. Hence, a very lightly optioned car, no showy mods, and more sensory involvement. Dass how AH roll.

Omar, A lot of the Grand Am guys use this intake on their race cars. I really doubt those guys would put anything on that loses power.

Quotes source post: 5191292

that's reassuring.

Quotes source post: 5191292

Don't be so sure. What saves their ***'s is re-mapping the ecu. As I can speak from experience ...... 2 HP maybe. Theo

Quotes source post: 5191512

Several guys have reported very good dyno results with this mod (w/o ecu changes), others have reported small gains (all can be found with a search). Racers are not into sound and bling, if they are putting them on the cars (with or without ecu mods) you can bet they are getting some sort of gain (more than 2hp) out of the setup. If they could get the same gain w/just a re-map, why would they bother installing this intake?

Quotes source post: 5191512

something like a GIAC or revo? or would it have 2 be custom?

Quotes source post: 5191181

since when does "no showy mods" have anything to do with being more or less edgy 993 style? face it. you drive a boring looking 911 when the inner-younger you wants all the floss just that you'd look funny trying to pull it off in your wise old age and the mrs would mock u. j/k bruce u know i got nothing but love for ya anyways, the previous owner of my car installed the EVOMS and GIAC flash at sharkwerks. if it were me, i'd do the evoms again ($1K?) but would be hard pressed to spend $1500 for the GIAC flash or any other kind of flash. i don't think it makes any sort of noticeable diff as i ran on the stock mapping for a gas tank and couldn't tell. so when people are recommending one brand flash over the other... it's complete salesmanship/hairsplitting. the howl at the upper reaches is very loud and howls like a wolf at nite. i adore it. Best, Ben

Is the intake really $1000? If I were in the market for an intake I would have trouble justifying the extra money for an Evoms over the K&N system.

Quotes source post: 5191745

I do drive a boring looking 911, it's true. But I really do prefer the stripped-down thing, seriously. My wife is an up-for-anything kind of girl, and it's certainly not about money (she thinks I should be in an Aston). I'm just a low profile guy. I even wear a Submariner, which I recall you also thought was terminally boring... maybe I should get my *** to Sea-Tac for some attitude lessons while I still have a chance...

You can guesstimate your power using stock data: 2004 C2 = 5 second 0-62 with 325 hp 2003 GT3 = 4.4 second 0-62 with 381 hp, lighter, fatter tires 2006 GT3 = 4.3 second 0-62 with 415 hp, ram air hasn't kicked in yet (of course a stock 400hp 993TT will do 0-62 in 3.6 seconds, so you will need to equilibrate) Using these to plot a curve, you can see 1/4 second less time for every 20 hp up to 365, and .1 second less time for every 20 hp over 365. This is murder on my clutch, buy it has helped me to decide what to keep and what to throw out. (I kept my EVOMS CAI)

Quotes source post: 5192037

Not a bad idea, but 0-100 or 1/4 mile times would give a better picture of power. A big factor in 0-60 time is traction.

Quotes source post: 5191574

There is really no need for custom mapping in a case for street use. REVO is actually used by a few KONI CHALLENGE 997 cars. With & without the intake. Those with intake, as I mentioned earlier, 2 HP maybe. Other teams have gone different directions to see what really works for them and what doesn't. Mapping , exhausts are where the real gains are found since the teams can not change the headers. Theo

Anybody have a problem with the EVOM throwing a cel? I"m tempted, but I hear not so good things. d

Quotes source post: 5192232

No, the cell being thrown is from the K&N intake and air filter. The evo intake doesn't use oil.

Quotes source post: 5192387

Pretty sure mine does... Never had a CEL, though. Pretty easy to live with, actually.

Quotes source post: 5192387

Both use a pre-oiled filter. However, the K&N seems to throw CEL's (according to many on this board) and the EVO's don't (according to many). I've had an EVO on my 986 for over 6 years with no CEL.

Quotes source post: 5193229

wanted to come back to this: apparently people have been installing the maf backwards in the K&N (i didn't even know this was possible). And that was the source of a misread, or so they say. Also, K&N shipped their intakes absolutly drenched in oil. Do yourself a favor and wash the intake and reoil it with less oil, or switch to the AEM oil-less sport filter for the sake of your MAF.

WHAHAHAHHAHAHAHHHA I really like the GMT2 Ceramic, but sold it because it was still a wee bit conservative and I didn't want to spend $15K on two watches. I have my limits that's for sure. I bought my Omega moon watch many years ago that I won't ever let go due to sentimental reasons. WIth the money from the Rollie sale, I picked up a wrist clock aka the breitling bentley 6.75 with the black gator strap. I know you drive the car the way it is cuz that's your style just like my style and level of normalcy is diff from yours and rightfully so. I didn't ever think it's cuz you really wanted to, but the missus or funds were stopping you from doing it. Notta once. Seriously, I came off like an arsehole so I apologize for that. My bad. I'd love to see my boy BruceP in an Aston Martin DBS. With his Rolex on. So Bond.

Somehow it never feels personal with you, bruh. No apology necessary.

Anyone know what the recommended process is to replace the air filter on the EVOMS? I jus got a new filter, but saw the thing and realized it's not as simple as yanking out the filter.

disconnect the maf tube from the rubber piece attached to the throttle body, the tube then can be pulled away from the filter ring and filter cone. Then you just wedge out the filter cone and disconnect it from the ring. Then just put the new cone on the ring and reverse the process. It easy to do. The fact is the I need to check and fix that damn maf tube and rubber piece are attached everyday I go out.

i also had the evo on my previous c4s for over one year and never got a cell. i made a modification on my setup based on a condition that i noticed after the install. the snorkel did not quit fit around the rubber gromit located on the engine lid. this lead to a slight but noticeable whining noise at cold start-ups that eventually went away when the engine was warmed up, but this got old real soon. also the possibility of sucking in hot air from the engine compartment was possible due to the poor fit. to resolve issue i actually removed the snorkel from the oem setup, which i think is a much better design because it actually forms a seal between the rubber gromit and snorkel which has a flange all around, and fitted it to the evo body. I cut the snorkel from the evo and slid in the oem snorkel in its placed. utilized a small beed of silicon to close any small gaps that were present. the end result was great and cured the whining noise. now i had the best of both worlds. i attached a pic for reference.

I don't think it's supposed to be replaced. I think it's supposed to be serviced, ie. cleaned and re-oiled.

you can re-clean/re-oil it but you still need to get it out of the box for that to happen or to replace it just wriggle and pull it out...you'll have to apply some force to it but there's no other way.

Quotes source post: 5327241

Oh, no, there is another way. You do it like this: - open wallet - remove credit card (likely still smoking from last mod orgy) - pay the nice man - go for espresso - drive home

Quotes source post: 5327241

I figured it was just a case of wriggling it to get it in and out... a tight squeeze, but it should be doable.

Quotes source post: 5327253

I bet you say that to all the girls.

Quotes source post: 5326909

thanks for posting this - I agree that the Evo Snorkle does not line up like the oem.....in fact it is quite a bit off IMO. Something that EVO needs to address especially for the price they charge...and I told them, but they seem very non caring. But I was contemplating doing exactly what you have done. Did you rivet the oem to the EVO after the silicone....nice. I want mine to line up exact...am I asking too much.....

Quotes source post: 5327256

Hey, it's a great line and seems to work.

Quotes source post: 5327337

yes i had a couple of small self tapping screws and used them to secure both pieces. you can see them in the pic. i used the silicon afterwards. its a pretty easy mod resulting in the snorkel lining up exactly.
