New Modded Hacked Airbox

Hello guys I might have something that I have not seen on the forum yet.
Still need to clean it up a little bit. Maybe some paint or something.

Just installed pvc piping where the first resonator connected to the "snokel". Just found some pvc laying around that I used. Put a 90 degree curve on it going away from the engine to the driver side. Then stuck a pipe that converts into two pipes and put a zip tie around the pipe and the fan guard to keep it from moving.

Picked up this spectre high flow filter from auto zone, part number is 884309, only $20.

Drove around for at least 40 min. Super smooth and a hell of a lot better then my bomz ram air intake. IMO probably the best cheapest way for better flow and more cold air.

Also after driving I checked the uim with my hand and it was cold as hell. No hint of heat what so ever. Can't really brag too much since I live in MN. But damn.
Has anyone experience this anywhere else?

I don't want to be an *** hole but that doesn't look very good. Are you concerned about water sucking up into your engine? The lower air box there is really for sound reduction moreso than anything else, removing it and running that pipe down may actually hurt power even if it does make it louder.

Intake manifold temperature won't really be impacted by your air intake tubing, it will be greater impacted by heat soak from the fact that it sits above the cylinder heads.

It does not make it louder at all. Maybe a little from stock, but it is way more quite then the bomz cone filter. Its annoying really.
About the engine sucking up water, I'm no expert, but usually the high flow filters stop water from getting though right? or is that only some filters? If that's the case I could just get a bypass valve.
I really did not feel a loss of power from my other intake with the snorkel fed ram air intake. I can still burn out in first and chirp second lol.

High flow filters dont stop water, to stop water you will need an intake bypass valve like this

Where's your splash guards?
That intake has been done before, there is a name for it, can't remember off the top of my head. You could have taken out the resonator box and piped into the inner fender rather then under the car.

in order to suck up "water" or "enough water" to cause damage; he would need to have the little Y bend under the car submerged in addition to having his underhood mounted snorkel submerged as well. Long as there is an some other place for air to come in, the engine wont suck up the water like a straw

At the point where your snorkel and that thing under the car are both submerged... your in a flood or river and hydrolocking the engine should be least of your worries.

Intruguing, but I'm more interested in your radiator core support repair. Mine isn't rusty, but I think my sister's is. Is that just a steel plate with some holes drilled in it?

I'm really not sure I see the point in replacing the support if a solution like yours works and is much cheaper. That's several hundred dollars' labor saved.

Yup, the truth. It takes ALOT of suction to drawl water from that low to the high point (throttle body)... An aem bypass will probably just take away any gains an intake provides (which is what? like 3 whp?)

All i have to say is you have some ***** driving around MN streets like that.

Just slap on a 00vi and call it a day if you want to do some intake work.

Well we got a **** ton of snow up here. I did have to take off the pvc at the end of the night b/c of the 12" of snow. I will probably modify the pvc a little bit. Shorten it up a little and maybe paint it black or something.

Also my new rad support goes around the whole top of the support. The crossmember bolts are threaded through to the top with a nut. Then there are two more bolts on each side with a washer and nut. Could be really dangerous in a couple years of rusting.

I'm not really doing anything more to this car. Its just going to be a beater winter car. It has ****ty scratched up paint and decent amount of rust to **** you off.
I am starting to research on the 3.5 swap. Sounds overall one of the best, fairly cheap mods. Hoping to put in a new shell this summer and swap out my mods on my current car and put it on the new one.

Yep this has been done before. A much cleaner look then using pvc is to use rv sewer hose. Looks a lot like dryer vent hose.

Another neat Idea if you autocross or race track your maxie is to rig up some of the dryer vent style stuff to the rotors.. Keeps them a little cooler.. Looks ghetto but seems to do alright.

When you shorten it up and you got the right fittings you can fish that pvc behind the bat down the fender and out the fog light if you don't have them. If you want you can stick a 3'' to 2'' coupling on the end and get ram air. Get a hole saw and drill a hole in the air box and connect the pvc pipe to it and get a drop in k&n filter. I did this when I was 18 back in 2002 and I have had many custom intakes since then but this is how I made my first hacked air box. With that mod and just a muffler I ran a 15.2 and my second run I ran a 15.1 and it was 90 degrees and the intake manifold seemed a lot cooler to. If I remember correctly the bottom 90 I had drilled some 1/4 inch holes in it to drain water just incase and made a screen for it to. Saw this tred and brought back some memories just trying to give you ideas.

I should of added this in the last post but pluming trade runs in the family and it hard to fab the pvc pipe and the fitting correctly but can be done. I had to go under the frame by the fog light tight fit. I recommend any who try this take fender off but I did not.

not bad. But im not really convinced this is more effective than jus running the snokel by itself.

Looks clean tho. no ducttape ftw

Nice thanks for the comments.

I did not know a lot of people have done this. Why is it not in the stickies?
I would much rather do what I did then just cut a couple holes in the lower air box or resonator.

I expect to get more cold air running up the pvc with the snorkel instead of just relying on the snorkel itself. Sure its only max of 5 hp, but it's really smooth and quit. I can finally hear my exhaust rather then the bomz racing nonsense.

You do it my way you will get more cold air/ram air your way is just adding a big straw to take longer to get to the engine. The reason I made the hole was to get the full effect of the ram air it did make my car faster. I have times to prove it but if your happy that's all that matters happy wrenching.

There was a member on here a while ago who went all out with this idea, and I think at the end of the pipe there was a little air dam to get even more air into the pipes as well.

It was some extremely creative stuff!

I did to if you read what I wrote in the first post I made on the subject I had my pipe came out the fog light with a removable coupling 3'' to 2'' . I have moved on and I have a CAI now and I was trying to give you guys some suggestions from what I did when I tried this back in 02. Instead of having the pipe on the ground not getting any air forced in to it. All so for those of you that don't want to drill holes in the air box replace it with a cone filter and get an air dam on the front of the filter and connect the pipe. = short stem intake that get's ram air just saying might work out better and a little easier.

Still trying new stuff. I tried to make it as high as possible, but still get some forced air in there.
