update from this post: https://honda-tech.com/zerothread?id=443182

I dont have the time to fabricate the carbon fiber or fiberglass that I wanted to make.

So I bought a duct from i/o port racing in lafayette, ca.
http://www.ioportracing.com/
It is about 15 minutes from my house, and they had it in stock for $20.

I had already dremeled out a big hole before. I had to take out even more plastic this time around. if you look at the bottom two pics, you can notice the difference in the size of the hole




this is the before picture of how big the hole is.

here is the duct un-molested


next was a matter of triming the duct to follow the curve of the bumper

I was able to trim the duct while it was attached to the bumper.

there are 2 bolts that attach the duct to the bumper that are hidden that are on top. then there is a zip tie that attached the duct to the radiator support for a firmer placement.

now it just needs some trim to go around the duct to hide the cut marks from the dremel and the gap between the duct and bumber.

lol! well its not the most attractive ducting I've ever seen but

 

So after all that hard work, days, weeks and maybe even months of planing, trips to hardware shops, cut front bumper, time and money invested.....does it make a difference? I'm working a similar project with a 5th gen civic. Luckily some 5th gen models came with a port used for fog lights, but can be used as an air duct opening.

 

I had the same concept for my civic. I used the bottom protion of a Mustand 5.0 air box, and hid it behind the grill. It has a 4"outlet on the side, that I ran ducting from to my intake. works great, and its nice and hidden

 

Looks like **** bro but im sure it does give you some more HP.Keep working on it and it will looks nice.

 

Spray the black funnel lookin thing white, it might make the front end more coordinated, just my $0.02

 

yea it looks really out of place in the front of the bumper like that, are you sure you coulent have put the duct in the grill somewhere?

but i think if u paint it white and clean up the cutting lines, it will look nice

 

yeah, i know it looks kinda ghetto rigged.

yes it makes a substantial difference. I think with the heat shield cold air and big duct they all add up. by them selves it is not much though.

I know i need to paint it. and from far away it doenst look all that bad.

I still have more effort to put into it to make it look nicer.

I was just focusing on getting it working and making more power, vs how it looks.

my car is going for cornering/braking accelarting ability over looks. asthetics are last priorty

 

Looks like ****.. but I like its purpose. I kinda have the same thing for my car. Bought dryer duct for $10 at home depot and have it sucking cool air from the front of the lower opening.

 

Looks good bro, just clean it up with a little touch-up paint.

 

Maybe do it to the other side take it to a body shop get cleaned up and nice mesh it maybe? Dont paint the funnel white

 

here is mine.. kind of like your but in the grill..

 

I think it looks better in the grill and plus you didnt need to hack up part of the bumper. Looks cleaner in my opinion.

 

Not to impose an your post, but it put an ideal in my head. What do you guys think about running something like that, but off of one of your vents from your car ( if you have as). In the summer you could just turn on the ac and it would be pushed straight to your intake. It sounds like a good ideal to me especially when your racing on a 100 degree day. Any thoughts on this ideal

 

how did you manage to bypass the radiator? did you put in a small half size radiator, because i was trying to bring a cold air feed from that location but the freekin radiator is totally blocking the route!!

 

you need to clarify your post.

it is bad for your a/c to be on when you are revving high. it wears the a/c motor out fast.

any benefits with the a/c would be offset by the drawing of hp by using the a/c motor.

the reason why I didnt put it behind my grill is for 2 reasons.

-you cant get 4" ducting to fit
-you have one big 90* bend when doing that

other than that, it is a good way of getting cold air into a duct. there is probably more air flowing in the radiator area than on the bumber where mine is.

 

Well my hat off to you bro, Good job at doing it

 

did you just used a piece of sheet metal for the heat shield?

 

You've got the right idea! Rule of thumb is every drop of 10 degrees results in 1 HP. I would take a lesson from Honda powered CART cars and install a mesh screen over the intake port just to keep the big stuff from geting into the filter... you are using a good quality high-flow filter right?
Also, depending on the weather where you live you may want to incorporate a bypass valve in the upper intake tract to avoid water ingestion and resulting engine failure. A little bit of vaporized water doesn't hurt (they used water fog injection in P-51 Mustangs in World War II as a power boost. Water, when heated expands at a greater rate than fuel) but if you get into big puddles... expensive ouch! Check out AEM CAI & bypass valves. Some say it isn't required but again how much is an engine replacement worth?? That's my $0.02 worth.

 

i don't think it looks good but it will serve the purpose i guess... i would watch out for puddles and **** like that. i would have done something like the guy did in that red integra, now thats MUCH better, good job gsrtyper

 

How come you didn't drill out one or both of those black plastic bits in the grill just to the left of where you mounted your scoop in the grill? I've been meaning to take a look for some flexible tubing at HomeDespot, say 1" or 1.5" in diameter to run up to the airbox from them. I would also keep some sort of intake along the stock route in case two 1.5" intakes aren't enough or if I hit a deep puddle. Just my 2 cents.

When it rains, I would keep a rag and a rubber band in my glove box and put that over the outlet part of the scoop in the engine bay. Like the other guy said, u don't want a tsunami of water rushing up that piping.

 

A regular cold air intake would have been better. If I were to cut my bumper at all for that, then I'd choose a better location.

 

yea thats alot of trouble just for like 1 or 2 extra hp.....am i wrong or did i not see a filter?
