For a 350 TPI (92), I cut out the crap right below the air filters, but haven't yet run tubes for ram air down to the foglight holes. You know the plastic dam that is right under the filters and in front of the radiator? Can I remove that all together or does it serve a purpose I wouldn't understand and I need to run the ram air tubes through it?

Also, what's the best material (tube, duct, whatever) to use for the ram air tubes here? I'm talking something I can go out and easily buy, not have to make myself. I wouldn't have a problem with cutting it off if needed, obviously.

 

that plastic piece right underneath the airbox thing is to help get more air to your radiator i think. i just completely took mine out and chucked it, had no problems with overheating whatsoever. as or what to use as ducts you could get some dryer hosing or ac ducting either of those will work, mine was a simple plastic type which works great. i've also heard that the dryer hosing that is the aluminum type works better to keep the air colder but i can't back that up. the plastic ducting ran me i think $5 for 10 feet, your local hardware store should have some

 

Yes any of those tubings will work - and this "free" mod is something anyone with the dual snork intake should do - tossing that stock piece of airdamn won't hurt as long as you invest a small amount of money into a lower temp thermostat and make the fan turn on at a lower temp as well - just to ensure that you wont hurt anything. But i agree it cant harm the car if you just rip it out anyway...

 

i can back up both of you. i recently di dthi smod. yesterday actually. i used the aluminum flexy dryer vent. i bought the larges ti could and it still wasnt big enough so i had to do some ingenius thinking. so here is my mod to the cool mod.

supplies :

4 ft of the largest alum. flexy duct

1 roll duct tape

1 roll alum duct dape (optional)

2 nice quality plastic bags

1 coffee can

after you cut your boxes i would advise you take out that little plastic thing your talking about i just pulled mine out completely, i havent changed my temp thing yet though, and i dont really plan to. if it bugs me i will make a new one to put on or put my old one back. anyway i took it out and the two little boxes that ar ein your front bumper.

i first stretched the alum duct stuff as tight as i could around the little box thing that goes infront of the car. its hard, so after i got it on i went around it and sealed it good with duct tape(yea duct tape!) then i used the shiny alum duct tape to make it look pretty again and not so ******* (the nice thing is this alum tape i ssupposed to be heat resistand) i did this to both little ducts, giving 2 feet of stretchy alum duct on it

next i grabbed my air boxes.. the ones you cut the bottom out of. i cut the handels off of the plastic bags and taked them around each of the boxes. think of the air box with a bag taped to the bottoms of it as if to catch anything that drops through it. i did this to both boxes.

*for this step keep in mind the coffee can is to maintain a shape to the bag, you want a nice large shape.

now i cut the bottom of the bag off, and i put the coffee can in the middle on top of the bottom of the air box. i now wrapped the bag (with coffee can in it) with duct tape, round and round tight and i made it so no plastic was seen, it is advisable to do this a couple of times for support. after i finished with the ducttape, your guessed it the shiny alum. tape. i did this to both air boxes. then i removed the coffee cans, its best to pull and twist it so u dont pull the tape seal off of the air box.

next fo inside the bag and cut any of the excess bag off. don twant that to get in the way of the air flow. and if possible tape down as much as the inside as possible.

now i put the boxes with the duct on them in my car. and i used the 2 plastic clips for each to re-install them. then the airbox thing. i shoved the duct in the newly formed round ducttape bag concoction and taped it around both the concoction and the alum vent to seal it then i used the shiny tape to make it pretty.

all in all with the time to consider what to do, and the drywall holes i put in my garage this job took me two hours. it took forever to get that plastic thing infront of the radiator off. its a bitch. now this may sound really rednick but i did an excellent job at it, and total supplies cost under ten bucks. it isnt free but think of the alternative.

i hav ea few other cool mods that are worth the time cheap easy and verry practical. if you want them send me a pm. i want to post it on the tech articles but i dont know how to get a hold of the guy that runs it. ahwell. hope this helps. if it dont iu just gave u and me a headache and wasted at least 5 min of your time. yay

 

I know the flexible aluminum drier vent ducting is easy to work with, but if you can use PVC ducting you'll have faster airflow due to the smooth inside surface. As an example, I've read that corrugated drain pipe has 9 times the frow resistance of smooth walled drain pipe. The pipe in effect flows air, or water, as if it was narrower than it actually is due to the increased turbulent resistance. The PVC can also easily be flared at the open end which has a big effect on the ease at which air can enter the tube. Here are some articles about making cold air intakes which mention these things:

Flare the PVC, but aren't you just going to slap on an open element filter? Unless - you are saying flare the pvc thats gathering up the air and then the air flows to airboxes with filters, in which case I would agree. I just read something about that on another board - air has a much easier time entering flared piping, or belled as opposed to straight cut.

 

Yeah, you're right. In my case, just using an open filter would allow too much hot air to be used, I felt, so I chose to put a cold air pickup on the existing airbox. I did modify the filter to allow more airflow too.

 

On a dual snork? I think the ram air is useless until youre on the highway or coming up on the end of the 1/4mile strip, but the gutted boxes with better access to air help for WOT at all rpm ranges.

So whatcha think? Better? Definitely worth it huh?

 

yes i think its definitely worth it, takes about 30 mins of your time and 5 bucks and yes its true that you prob wont' notice it too much until you're on the highway or upper RPM's but hey i need all the help i can get heh. i'll take pictures when i go home for thanksgiving break if anybody still wants to see how i did it

 

Yes pictures - good.

 

Just out of curiosity, what posses you people to do this stuff to your car?

 

In my case, I only do a few small modifications. Not at all like some people who like to rebuild cars as a serious hobby. For me this is only a tiny hobby, so I only do simple mods. Regardless of our abilities and interests, I think we all like to know we're doing something to improve performance. It's a feeling of accomplishment, or pride for those who like to race, or just a good feeling knowing you've been able to make something better than it was originally. Anyway, that's what's in it for me.

 

the need for speed haha just kidding about that even though that is partly true. i love cars, how they look, how they drive, how they work and everything about them. since i'm a poor first year college student i have to rely on small cheap little mods to help my performance until i can one day do the things that i would really like to. and besides its a great stress reliever, got too much on your mind why not go work on the car? works for me

 

We do this b/c we can make the cars faster and better handling.
Take a look at it this way - it's all in what car you like (for us it's obviously thirdgen f-bodies). Take any car, any make/model, and you can basically modify so drastically that it's really fast/great handling... so it all boils down to, which car you like the looks of.

 

Its a cai guys, ram air is a myth, at least at speeds our cars will ever see.

 

Back on my stock L98 I picked up a consistant 2 tenths with my Random Technology ram air that is not a myth.
