Hey im wondering could I drill a whole in the wheel well near where my pop charger is sitting and then put a small tube right where the hole is and lined up so that the air blows directly on my cone intake? Will this have a similar effect to a cold air intake? If I have a heat shield blocking the other air from the engine bay?

 

A heat sheild that keeps hot air away from your filter is a good idea. Anything that keeps hot air away from your filter is always a good thing. As far as drilling a hole and placing a small tube inside the wheel well, that's another story. You would need air from the front of the vehicle being forced into this tube, thus blowing on your filter. And this still would be sub-par to a true CAI. By the time you drill a hole large enough, and run tubing through your engine bay you will wish you had a CAI to begin with. Do the best you can with your pop charger without cutting into your car for now...and save up for the CAI. That's my vote.

 

Ahhh... just take off your fender and run it like that!!

I'd say save up and get a real CAI, like 5spd92SE said.

 

I wouldnt put this past anyone. I have heard of Honda's running at the track with no fenders and 4 spare tires.

 

Body panels are only for aerodynamics anyway..the weight reduction would be nice...Hmm, maybe..NAW. I like my dinged fenders and peeling paint!

 

actual spares i doubt...steel wheels...yes

 

No really, a guy tried to pass tech on 4 doughnuts at SIR.

 

I wish people stop being cheap and just by a d a m intake. Or you could just cut a hole in your hood and use a milk carton as a filter. Lol come on now these post have to be better then this

 

get used to it...modding is expensive and people have decided to do it as cheap as possible (and it shows). Notice how a large % of cars are modified in some way shape or form now adays. Most people (like myself) technically can't afford it

 

wanna pay for everyones?

if you really want to do this, you have to find a way for the air to go into the tube, place it somewhere in the front of the vehicle and use dryer ducting for cost efficiency.

 

i seriously hope you're being sarcastic...if you can't afford to buy and intake then why even bother rigging something that will most likely be inefficient anyway...

 

Whats a intake cost 40 dollars? I mean come on man. I know it cost money to but stuff for your car i never said i was rich but i am sure you can afford a intake instead of cutting holes in stuff and buying tubes from home depot

 

I disagree, I think a $40 intake will probably do more harm than good when compared to cold air routing.

Most, not all, $40 intakes (open filter in the engine compartment) will be LESS effective than routing cold air to your stock airbox with a good filter.

I have noticed that this is much easier to do on a Honda than in a Nissan...so he might have to get real creative with his MAX.

 

Relocate the battery and route your intake towards the headlight, remove headlight for track use. Cheap mans "ram/ cold air intake".



This is what SteVTEC had to say about intakes:

"Do you guys realize the volume of air that the VQ is pumping in and out every second at full throttle?

With a 3.0L engine at 5000rpm and 100% throttle, you are bringing in 1.5L of air every revolution. 5000rpm = 83.3 revolutions per second.

1.5L x 83.3 rps = 125L/s

Now where do you think this air comes from? Is it all just loitering around the radiator and engine block taking its good ol time to get nice and warm and cozy before it makes its way into the intake? Or is that air zipping from the outside, through whatever underhood path it takes, and into the intake tract so quickly that it doesn't even have time to heat up much, if anything, beyond outside air temperatures at all.

Yeah, if you're loitering through town at NIL throttle there is very little air flow and I bet intake temps would be higher. But then you're not too concerned about making power are you, because your foot isn't even on the gas. But if you stomp on it, all of that hot air nestled under the hood is going to be displaced by fresh air from the outside in a matter of no time with a flow rate of 125L/s."

 

He's right, the effectiveness of CAI is really arguable. Most of the gains you feel are due to the lower restriction and not the "cold" outside air.

 

A few of us Raleigh guys are doing some experiments with intakes using a intake temp thermo. I'll post any results we come up with in the future. We have a variety of intakes to use, and yes we are going to try the one behind the headlight probably.

I cant really tell who you are agreeing/disagreeing with by posting this...but...

it sounds like SteVTEC is answering a question pertaining to the material that the intake tubing itself is made out of. We are talking about the source of the air. In other words, we dont care what the straw is made out of, we care how hot the air being injested is.
Forgive me if I took your message out of context.

I do agree that once the car gets moving, the air under the hood cools down. But I have noticed when running an open air filter under the hood on a hot day, the hesitation off the line is significant.
The only car I have seen a test done on was a Supercharged Civic in SCC and my own personal experience.

 

I think what he is saying os that at 125L/sec, the hot underhood air will be ingested very quickly and a second later will be drawing in outside air. Really. 125L is about 4 cubic feet..4ftx4ftx4ft. There isn't nearly that much volume under the hood taking into account the engine and other crap under there..I don't think he was referring ot the material of the tubing. But I will say this, that hot air getting sucked in for a second cause cause sluggishness at part throttle and for that split second when you want to get the jump on a ricer! I am interested to see yourr results with the thermocouple and various intake combinations. You are going to put the thermocouple near the TB right? That would be the best place for it cause you want to know the temp of the air entering the engine.

I actually put a temperature probe right inside of my pop charger to measure the temperature of the air being sucked in. I believe that the effectiveness of a cold air intake is minimal unless your at a track.

At idle the temps in the hood could get pretty hot if the car just idled for a while. If however the car was moving at a decent speed the temperature would stabalize to the outside air. Once the car stops moving it would take a few minutes before the air would start to warm up.

In other words yeah, if you are doing some racing at a track and your car is just sitting there idling for several minutes then a cold air intake will probably make a difference. But for regular stuff on the streets where the car is either moving or idling for just a few seconds at a stoplight then it probably isn't going to make that much of a difference.

Then again, I haven't actually tried a CAI I'm just going off of the results from my temperature testing, so I will reserve final judgement for when or if I actually get a CAI.

 

Wasn't trying to argue, just throw some valuable and interesting info into the convo. Next time you guys drive around for awhile pop your hood open and touch your intake (if you have a pop charger that is) and see how hot it is.
The other night there were two 4th gens present with pop charger intakes. One was cool after driving, the other was kind of warm to the touch... very interesting. So that's why we picked up the intake thermo.

 

Thnks guys so what some are saying and others are arguing is that the effect of actually getting cold air form outside is minimal. The gains are mainly through less restrictive piping, SO since I have a pop charger intake right now, I could get some gains by replacing the stock rubber piping with say warpspeeds upper intake tube piece for 75$? Instead of getting their whole cold air intake system, and if Im correct this would make my intake a Hybrid Intake?

 

Yes. Just make sure your filter will fit inside the fender-well when you get the Warpspeed CAI piping. Sometimes the filter has to be a particular size.

I am very interested to see the results of some testing...

 

join the Accord intake crew!!

Thats what I did. There is a guy (or several) on a certain auction site that sells 90-93 Accord Intakes for $26.99 plus shipping. It fits the VG. And it fits quite well if you ask me. As for the effectiveness of the CAI, there have been write-ups in the past that point out the fact that air in the fenderwell is not that much cooler than the air in the engine bay, esp if you're using a heat shield. Don't know if I agree with this or not but its something to think about. Also there has been talk that teh long tubing of the CAI causes turbulence in the air, further reducing the CAI effect. But any way that you can get more colder air to your intake quicker is going to help a little. I've considered running some type of tubing up to my filter just to see if noticeable gains are......noticed?
