I just got done installing some more parts on my Evo.
AMS Cold air intake
AMS Upper intercooler pipe
Oil catch can

All I can say is that it feels alot more powerful than before. I'll have to get it dyno'd again on the same dyno as before so I can see the difference in numbers.

AMS stuff looks very clean. Grat on the nice Looking Engine Compartment. How did teh Intake Install go. From the forums it seems like a lot of people are having problems with it?

Thanks, the install wasn't difficult at all. But for people whom have never messed around with cars before it maybe a little difficult since it didn't come with any instructions. The intake took about 20min to install and the upper intercooler pipe took about another 20min.

Do you have an exhaust on it?

what kind of numbers were you running before the install?

297.2 whp (344.1 engine hp) and 44.3kgm torque, which is about 40whp higher than stock.

SiC! Mind snapping a pic of your fuse box for me? :X

Looks nice, can't wait to see your new dyno!

Nice too see you repping the USDM over there :D

Nice, but that's not a Cold Air Intake, that's an SRI.

Looks great!

What purpose does the oil catch serve?

Correct me if Im wrong but isnt the catch can suppose to be installed between the valve cover and the intake manifold(not the intake)

Yes you're right but alot of peeps refered to them as CAI here. I'll have to make a box around it or something to prevent the engine heat to be taken in.

There are 2 PCVs or maybe 1 PCV and 1 breather on this car. Both are on the valve cover. One went from the valve cover to the intake pipe (between MAF & turbo) and the other goes from valve cover to the intake manifold. When installing the AMS intake, you'll have to use a catch can since there is no port for connecting this breather, blow-by, pcv, whatever you might want to call it to.

Gotta love the look of the AMS parts there, I sure do :rock:

What purpose does the oil catch serve?

There is a hose that comes from the valve cover to the stock intake. That hose is to relief blow by gas pressure within the engine. These gases are returned to the intake for emission purposes. On the AMS intake, there is no connection for this hose so you have to use an oil catch can to prevent this hose from spitting blow by gases and small amounts of oil within your engine compartment.

**Blow by gases contain compressed air/fuel & exhaust that gets thru the piston rings. It also contains small amounts of engine oil that gets shot out by this pressure.

The oil catch can is an item that many people think they need, but don't really. The OEM PCV and valve cover nipple work together to make sure that there is always homeostasis in the crankcase as far as pressure is concerned. The PCV is inline between the intake manifold and the valve cover and is a one-way check valve. Under positive intake manifold pressure (on boost) the check valve closes and the crankcase fumes are routed out of the valve cover nipple that goes to the intake. The vacuum created by the turbocharger suction aids in evacuating the crankcase of pressure and fumes created by combustion. When off-boost, the reverse happens. The negative pressure in the intake manifold (vacuum) sucks the crankcase fumes into the intake manifold and back into the engine to be re-combusted, thus aiding in less unburnt fumes to be emitted into the atmosphere. Fresh air is sucked into the crankcase by the vacuum created by the PCV through the valve cover nipple attached to the intake. The system helps ensure that pressure will not build up excessively in the crankcase, which will definitely lead to a piston ring-job in the extended future.

SiC, the way you have it set up, I am a little concerned, mostly at the way AMS did not create a provision for the valve cover nipple to be re-routed to the intake pipe. The stage that your motor is in right now, does not require the use of an oil catch can. You'll find that you're not really going to have that much collecting in the can. I can 100% guarantee you that you'll catch more water vapor in the can from the car sitting over-night than you will catch oil. Also, it looks like the can you have in there is an eBay special. Those cans have no substrate inside them to actually 'catch' the oil. By that I mean, a good catch can has to have something like steel wool or the like inside, because when the fumes go into the catch can, they are in hot gaseous form and when they contact a cool metal, the oil condenses on the substrate and will eventually drip down to the bottom of the catch can, thus doing it's job. I have seen those cans that you are using on the car and have cut them open to see if anything is actually in there. I found nothing but an empty can. Totally useless. The way the catch can is installed is partially correct. The nipple that you have just venting to air on the catch can will still force the fumes into your engine bay, and over time it will leave a nice misting of oil. And then you will have a nice layer of grime in your engine bay, as the dirt and airborne particles will stick to the layer of oil. That nipple should be routed to a nipple on the intake pipe so that the suction caused by the turbocharger will allow the fumes to be 'sucked' through the catch can, rather than 'pushed' by the crankcase pressure. The added stress of the motor having to 'push' the crankcase fumes through the valve cover nipple when under boost is something that can add to the likelihood of rings going bad before they should on a stock application.

Please, take nothing I say in the wrong way. I am not here to offend or belittle people. I just want to share my experience with a multitude of modifications that I have dealt with in the past and the results and would rather you do it right the first time than have to regret things later on.

My solution would be to take the intake pipe to a local fabrication/welding shop and have them add a nipple onto the pipe.

Not sure what metal they use in the pipe, but I would assume 6061 aluminum.

Yeah, the outlet pipe on the catch can would normally be connected to the suction pipe but it's open for now since there is no nipple. I dunno if you want to call it an ebay special but it does have steel wool inside and there is a drain bolt on the bottom too.

Catch can is a better solution, as it keeps you from spraying oil into the intake, clogging up the works, so to speak.

AMS has a design that makes that makes this a moot point for only $50.

Ah, much better picture. The original picture you posted, the two linear nipple design, I've seen on eBay and I bought one a while back because it was so cheap just to hack up and see just what people were getting for their money.

My apologies, as I only saw the top of the can. But you should still get that other nipple run to the intake pipe.

Honestly, if that much oil is getting blown by, then I think a compression diagnosis is something that should be done, rather than a bandaid fix like a catch can.

Hindsight be 20/20, young man. :(

Figure, he's got the intake already, ship it back to AMS, they probably want a restocking fee or something.
