I am a big noob when it comes to knowledge about engines and horsepower and stuff.
But I have a few questions.
Before i ask them, I have searched through the forums and FAQ, but if there is a thread i missed that will answer my questions, please let me know.
a) Does anyone have a homemade cold air intake for a stock 5m? Or no of a way to make one that doesn't look cheap? I can't find any other ones except the Rabidchimp one, and i don't wanna spend 190 dollars, or w.e it is.

b) Will a CAI actually increase horsepower or gas milage? i have heard both and idk if they're true.

Thank you for taking the time to read this, I would love to talk to anyone willing to hit me up with that technical knowledge about 83 Supras. I've been driving an 83 supra since I was 16 (i'm 19 now), and i haven't really gotten into them until the past few months. hit me up?

It is just a tiny increase and cooler engine sound.. thats all. It is more look than performance I think.

Yeah. When I read about them, I see that they increase power and better gas milage, but when I ask people in car clubs in stuff in town they say it's just cooler sound. haha.
IDK!

Well.. same thing with biggler muffler.. theoratically you will get better gas mileage but of course the way you drive will change (since it sounds so good) and you will get worse gas mileage lol. But really... just get rabidchimp's if you do want to get a CAI. Unless you are a good fabricator.

From what I have read the rabid chimp intake produces roughly 7rwhp, which is a significant amount for a NA motor.

Cold air intakes do alot more then make things look pretty and make a cool noise, that is a uneducated opinion, they produce lower intake air temps which will increase h/p and torque across the entire power band, cold air=dense=power.

I did say it increases hp.. i dont deny that. I just dont want him to think like those K&N air filter add.. 35 hp!!!! wooot wooot... maybe if the car has 400 hp already it can increase that much maybe. But really.. how much cooler is it? The pipe does go over the engine and the pipe gets pretty hot after a while.

Go to my website, in my signature. Click on Modifications and look at my cold air intake. You can gain significant power for zero dollars (just invest some of your time) with this mod. Can you think of any other ways to gain power for zero dollars? If so, let us all know.

Neither my intake pipe kit or cold air intake kits have been dyno tested. I recently came up with this - http://www.rabidchimp.com/mk2sup_rcp_cai.htm

In your vendor thread, he posts with just adding the CAI, not the upper intake netted 7rwhp, then proceded to call you a lazy ass.

How do I know my cold air intake has not been dyno tested? I've only sold one, and its not on the car yet. That was his home-made kit.

Reading the post in a vendor thread of "mine made xxrwhp" one should assume he is refering to the vendors product, If I was posting in someone elses vendor thread, I would say "One that I have made produced xxrwhp on the dyno, you should expect similar results, but in a much nicer finish". But then again, it wouldn't have given you the chance to act big and tough and wave the epeen around,


Aaron, I was not aware that you had only produced one, and based on the posters statments it eluded to him having one of yours, nice to see you back at it. I never did find a finish on your twins project for the 5m, is it finished?

my cai was just a k&n cone . i removed the old stock airbox, pulled out the bracket. then chopped 1/2 of the bracket off(gently and cleanly) because it interfere's with the filter. then just bolt it back in and put on the filter. total cost $67 for the filter. thats it.

Hey thanks for the opportunity. Reading the second line, one would assume that the users CAI is not from RC, paired with the word mine before it. Acting big and tough and stating an observation are 2 different things.

Two diffrent beings, two diffrent observations. Mine is a interesting word, being posesive meaning it either has, or of his own creation, I stand corrected.

But on a note to remember, CAI gains on a dyno are relative, as the filter placment also acts as a ram air affect, which increases HP the faster you go.

That is just a intake, not a CAI, a CAI gets its air from outside the engine bay.

Aaron, the rabidchimp CAI's are sweet as hell, i just don't have the funding for one. I'm not sure what i'm gonna do.

Just buy Rabidchimp's. This isnt a newer car where people can actually make money mass producing CAI for a certain cars and sell it for cheap. The thing is there are only a few MK2 running today. I cant blame aaron for charging that much because he has to.

When I owned a tC, new CAI started popping out on ebay for like $60 with filter included! lol

Word, reason HKS and Greddy don't care is no one would buy their products, no money in the MK II, now it is getting popular and you have someone investing alot of time into developing new parts, and people want it cheaper. Just guessing, aaron has to sell 10 of these before he sees any profit...

Home depot special :) Nice man!

Socal, your pipe that goes down, is it very easy to suck water? I want to do what you do but afraid of water.

i live in san diego, so sucking water is not a issue for me. even if it rains hard im not too worried about it. but if you live in a flood area and its flooding that day dont drive.

These guys KNOW this stuff.Lotsa cheap ways for a cold air intake.It DOES sound like horsepower is being made-it will impress the bystanders and the pasenger(s).

happened yesterday, just rain ,not a hurricane, fucking pumps.

also i knew ofa shop that had to swap a new v6 hyundai tiburon motor b/c they kid that drove it had a CAI during a summer storm wit hthe same results. stupid ass. replace a 1 year old motor b/c of water.

there are ways to get your filter up higher. it may take some plumbing but its doable. in front of the radiator as high as possible is one option.

Another way you can make a open air setup is 2 22degree tube (they are chromed plastic) to replace the black part that goes over the cams and then the Honda intake that you can find at Schucks or AutoZone (it is alumn) and cut the one end down a little so the AFM with the open air filter car fit. If you are running a stock header with the cover it would be alright to run the chromed plastic tubing all the way, but with my Pacesetter, I melted the tubing that goes over it (there is quite a bit of clearance) within a couple weeks.

But if I had the money, I would go for Aarons setup in a heartbeat.

socalsupra
10-23-2007, 03:32 PM
iv been looking in to a new setup; pre bent exhaust tubing. can get the straits in 3 ft sections and the bends in 90, 45, 22, and 11 degrees. one strait that you will have to cut and 2, 45 or one 90 that you will have to cut. or mock up one like mine with PVC and go to a muffler shop and have them bend you up one so its all one piece. paint it up with a high temp paint and your all good

10-23-2007, 03:38 PM
It's good if you do not mind having a roughly 4 pound intake. Unless if you feel liek shelling out the money and finding one that will do it with alumn and mandrel bends, but then you would end up paying more than what Aaron makes.

10-23-2007, 03:46 PM
hell you can make up for the wieght by loosing a few pounds or taking a healthy dump before you drive! realy whats 4 pounds?

Very true. I don't know how forgiving over time it would be to couplers, unless if you made a multi point support for it.

raven97990
10-23-2007, 04:24 PM
Whats 4 pounds? If that is your attitude over your car, think this for a second. New speakers, just 2pounds eachx4= 8 pounds, 4 pounds intake(12 pounds), Big fancy rims, just 10 pounds each(52 pounds), get my drift? Keep having a "its just weight" attitude and you have one fat car.

socalsupra
10-23-2007, 04:37 PM
im not too worried about weight, considering i have removed the entire ac system, some of the interior trim, rear seats, electric fan up grade, etc.... the car still does 0-60 in 7.6 and its a auto and i have 50 lbs of tools in the back. so i think im moving in the right direction.

83CelWA
10-23-2007, 04:49 PM
It's not necessarily about the weight, but do you think there may be a good reason why you do not see aftermarket intakes being created out of steel tubing? Steel is easier to work with and quite a bit cheaper. I guess it is more of a preference thing.
