Unhappy CAI for '97 Impreza 2.2L ... please?

Unfortunately, Larry has decided not to make his CAI for older Impreza's. Totally bummed me out. Does anyone know of any other CAI's that would work for my car for less than or around $200???

I'm in CO, so I'm already losing bunches of HP due to altitude, and Larry has claimed that with a CAI, I (or anyone else in CO, for that matter)could get back to stock HP. This is my most immediate goal, and I'd rather not have to settle for the K&N cone filter conversion, as I'd be sucking up the hot air from under the hood.

suggestions?

Have you tried JC Sports? They're here in CO, and I'm pretty sure they make CAI's for everything from a 1.8 to a 2.5...

Question

Does the JC Sports intake preserve the stock plenum? That was a major factor as to why I liked Larry's so much. I'd really like to keep the power in the low end.

Aren't we still sucking hot engine air with this intake?

I have one on my L as well, it's pretty good.
You just need to make a heatshield to block the hot air from being pulled in.

it looks like you still have your snorkus in there in that pic...

that would mean you're still not taking in the cold air...

c'mon Larry! you got us hooked on the Ganzflow!

Why would you say it's not pulling any air in? It's designed to pull air in from the front into the intake manifold.
When I took it off it was hotter in the engine compartment then when it was on. Hence I see it pulling air from the front at highers speeds and blowing it right into the direct of the tip of my cone filter...
Am I missing the point of it?
Either way I'm going to run some 3" Vaccum tubing from the front of my grill to the tip of my cone to pull more cool air in.
I did my heatshield today...

could you just put the sensor in the middle of th epipe, and run the pipe in to the fender, adn put the filter on the end of the pipe IN the fender, wouldnt this insure cold air, or would it get wet?

How could it get any cold air in a mostly sealed area (wheel well)
Also, a friend of mine has a similar set-up from place racing on his 200 SX with the cone in the wheel well, he got water in his MAF and ruined it, I guess it's a common problem with those type of set-ups.
I'm happy with mine

with that heat sheild in place, it makes a little more sense to me, although I still believe it's not quite as cold as an intake that runs tubing to the fender.

oh well, the important thing is that you are happy with your setup, which brings me to my next question... Do you notice a lot of power loss in the low end with that JC intake? I've read a bunch of posts that mention this, but how bad is it, really?

Also, most of these posts (well, nearly all of them ) are from RS owners. The 2.2L just doesn't seem to be as popular, although there are a few of us out there. This being the case, am I right to assume that the benefits of an intake, as well as the loss of low end, are magnified by the 2.5 RS as compared to the 2.2L because they are 0.3L bigger? Meaning that there is that much more space to fill with air/gas per turn of the crank...

I'm just learning here, so someone please let me know if my logic is off.

Wayne,

I was thinking of going back to my stock box but using the mandrel bent tubing from the first airbox to the second one just to see if there is a difference. I think the pipe I have now on the Ractive filter will fit. I think this may be the ideal setup to be sure you don't mess up the MAF. I understand that if you over oil the K&N it will get some oil on the MAF and blow it. Something to watch out for.

Frey, it is something you could do, but there's a little more engineering involved then just replacing the piping. That's why some of the intakes just don't work as they should. You have to maintain a certain amount of air coming in for your engine to function properly.
It may pull in water considering your wheels will be throwing it upward anytime it rains or you hit a puddle.
And Yes Sir, I do notice some low end loss, but the sound is PRICELESS, especially when you don't ahve an exhaust and you drop a gear and blow by somebody who is looking for your car to have a 4" tip on your muffler.
I like it for the most part, here's my advise though..
1. Buy a Kartboy MAF Filter Mount and a K&N Cone Filter (I have the filter mount for sale if you need it)
2. Reset your ECU and go.
3. I noticed a few extra horses and a preservation of ALL of my low end power.
4. I loved that set-up, but I'm just keeping the JCSports out of pride for spending so much on something that makes my car loud and slow
PM me if you want the Kartboy

That set-up works well for the RS, but he's got an L, we have 4 Vaccum tubes as versus the 97-99 RS which only has three, he will have to relocate one of the tubes going to the throttle body into some other source because the first tube coming off of it attaches directly to the pipe you replaced.

AFAIK most people just put a small breather filter on there. I'm guessing Summit has them.

Question

hey peaty, what do you do with those "breather filters"? I'm not sure I know what you meant by most people just putting those on. Instead of what?

Also, a note on the importance of cold air:

On Larry Ganz's page, he states that it's been reported that "every 40-60 degree drop in temperature will result in an additional 5-6% increase in power! That's as much as 10hp right there"

according to the chart that peaty provided, there is an average temp difference of about 20 degrees between the airbox and the fender. This leaves me with, at best, a 5hp advantage over a high-flow setup under the hood(non-cold air), and most likely, LESS than 5hp.

(my calculations: 60 deg difference = 10 hp, 20 deg difference = 3.33333hp)

So can anyone with a reliable and accurate butt-dyno whose tried both high-flow warm air, and high-flow cold air setups tell me if it's worth $100+ more for a name brand CAI?

(I'm pointing to you, Brys!!!)

I've seen one of those filters stuck on the end of the hose. I've only seen one motor that needed to do this. Someone let me know but I think the hose connected to the section just takes in air. Short of welding on a place for the hose you can get a close nipple and put the filter on the end with some hose clamps then secure the hose somewhere. Or just let it flop around like Keith

FYI - I did not decide to cancel our MY99 and older CAI - but the one we developed had an indefinite backorder on the shielded cold air filter WITH matching cold air hose that went into the inner fender. Can't sell what you can't get parts for.

So, we had to go back to the drawing board, and in the meantime now offer for sale the PRM cold air inline filters and a seperate 3" MAF adapter, until we have worked out the details of an intake design all over again.

You can go to www.imprezars.com/product2.htm#prmfilter and www.imprezars.com/product2.htm#mafadapter to buy these, and DIY till we have the finished parts.

Thanks,

Larry www.ImprezaRS.com

If you have the filter just sitting under the hood it will pull too much hot air. Check the thermal link I posted above. It shows that it's hotter. I measured 6 different locations while driving around. I think this is the cheapest and safest CAI you can do:

<IMG SRC="http://albums.photopoint.com/j/View?u=1471714&a=11073907&p=47912239" border=0>

It will pull air directly from the fender.

Totally Larry,

I know it was your supplier who let me down, not you. I've heard nothing but good things about your service and products, and I have witnessed the first with your quick replies to emails.

So, thanks.

But, might you have any idea when you'll get everything together? I know it's hard to tell with these things, but if you have an estimate to the month, it would ease my mind.

I know all the parts I need, but it is a matter of getting the (1) parts and (2) a car together at the same time, to get the measurements for the aluminum bend from airplenum to MAF, and from PRM filter to inner fender. Then there is the issue of a bracket to bolt the MAF to the chasis to deal with.

Unfortunately, I can't say when that will be, but for anyone willing to cut the aluminum with a fine tooth hacksaw, I can sell them parts to make one. However, there is a way to do this for less if you have the MY97-98 and can bolt the MAF directly to the air-plenum, then use dryer duct instead of aluminum to get into the inner fender. See my post about the PRM filter recently as a response to someone elses post http://www.i-club.com/ubb-files/Foru...L/022456.html.

Also, local volunteers for fitting an intake should email me. I already know I can hit up Bratmantlz for his MY98.
