The Auto Zone Disaster

4gotn · Post by **4gotn** » March 19th, 2006, 9:50 am

ok so i decided to build a custom cai for my car...i have a dohc so i figured id create a dual intake ( one short ram and the other a true cold air ). so yea..i made the intake..took like two days...lots of fitting and cutting etc. and somewhere allong the line i realized i needed a y pipe connection... simple problem right? so i went to autozone and bought myself a y pipe. had the usual trouble of geting stuff situated but FINALY i got the sorry sob done.. so anyways i get the thing done and out on the road... works great (btw.. if anyone wants to give it a shot pm me and ill make a wright up or something to pm you)...lots of torque.. so anyways i was driving down the highway and all the sudden i hear this realy loud scraping noise and then something hit the bottom of my car and then all the torque go out the window... so i flip out and look in my rear view mirror and some ford f150 is in the process of obliterating my brand new true cold air passage of my intake..so naturaly i pull the car over and cry for my intake and then pop the hood to see what was wrong... as im sure you can figure it out by now.. the stupid y connector from autozone was plastic with a VERY good alluminum paintjob and is now mysteriously cracked...so yea...ive had to drive arround lately with a dual ram air on my car ( drives funny ) and am now holding a grudge against autozone...
oh..does anyone have a 1.5' straight with a 90 on the end?

a duel filter is going to be usless. You wont get that much power out of it to even see a differents. Maybe like 2 or 3 hp on a CAI.

I would say that you would actually LOSE horsepower with that setup. Having two intakes will make the air coming into your throttle-body SLOW down. Especially since you are running N/A rather than forced induction.

youd think so but it actualy worked realy well
it turned out to be more of a dual cai rather then short ram/cai
i had a lot more torque believe it or not

Did you actually DYNO it?

I doubt it.

yea sure i did..i pulled it up to my big fancy garage and rolled that sucker up on my 4wheel dyno and just let that babby go

HELL NO I DIDNT DYNO IT
ITS A CAI FOR CHRISTS SAKE

you obviously dont have a clue about what your talking about so why dont you find your way out of this thread

There is no need to get so defensive. If you do something that someone questions they are gonna ask for some proof. No offense to you, but being new to the site doesn't help your credibility either. Hell, we even look sideways at some of the things regular members claim. I doubt Atlmx-3 is the only one that believes that your dual intake doesn't do much, because your throttle body is still the same size opening. Without pressurising the air that is going through it, it is not going to make much difference. If you had an air box before, I would say that it probably is an improvement over that. No need to flame.

better breatability
and no i didnt have a stock box
i had a ram air then i build off of it
being new to a forum donesnt meen you have more or less knoledge or tallent
key points made
more zelda

Agreed, but that doesn't mean that people will trust that you are knowledgeable until you prove it time and time again. Don't get caught with the Go-Jo or you will loose all credibility. LOL!

I see your point, But why not just go with a single, bigger pipe? I have a fairly big intake pipe on my ZE and I don't think that opening it up anymore would be beneficial.

obviously it worked great as it broke minutes into using it....??

well fix it back up and get some pics i'm curious as to how u managed to fit all that in ur bay??

dood sorry but he's right.

you know nothing about the physics of this stuff.

Its like saying "having a 6" intake on my car GIVES IT MORE POWAAAAAAAA"...thats a total lie & untrue.

Air intake velocity is what is important, if you mess with that, you ARE DECREASING power.

Making the intake bigger is going to decrease velocity. Your little 1.6 simply doesn't require as much air as a KLZE or V8, etc, even at higher RPM's. A 2.5" intake tube is the BIGGEST you should put on your 1.6 engine. Making it with a dual-filter or y-pipe on the intake end is going to further f'up your velocity decreasing power.

"but it feels faster" yeah..thats what everyoen says when they waste money & time doing something that really had no effect. I swear I hear people say "after i put those 45lb 17" rims on my car, it feels faster!" suuuuure it does....ur stock 13's weigh 28 lbs w/tires while ur new rims weigh 17lbs more. No way in hell that will "make a car faster", just like having a dual-inlet intake will "make more power".

Same goes for exhaust. on a 1.6, 2" is the biggest tubing you should be using, if anything 1.875 would be better for velocity while 2" would be better for higher RPM power.

basicaly what im saying is that it takes a long time for the cold air, at least a good ammount of it, to get to the throttle body so basicaly you add another filter on there to sort of help it suck a little more air in for a little more off the line bost...
i set mine in front of the rad fans so it gets decent circulation, not the best air in the world, wich seems to work well for my low end of the stick hp
maby if you get an extra fifty lying arround you could try it too..
tell me your opinion

XD
yea.. it got jared lose somehow..ill have to work on it..will take pics once i get the cam and new tube

and finaly
in relpy to Gro Harlem
if you read what i said above it does make sense
it may not be the best thing in the world but neither was the rotary engine when it was first bulit
PLUSSSS
i know it gave me more torque kause i could feel it
i took off as i normaly did with the standard cai on the car and ended up barking the tires on accident
it may not give me a hell of a lot of top end but i have a dohc..im sure i can make up for it in the long run..i plan on haveing a na car so ill just add higher compression pistions or something...im sure ill figure somethign out...
but still
the point is dont dissaprove it till you try it yourself
remember...wankle never got his idea promoted till someone else found out it was good for something too

why would i waste money trying something that I know will decrease power on my engine?

Takes some physics & engineering classes for the love of god.

Comparing a "dual intake" on a single-inlet intake manifold to the rotary engine is ridiculous. Simply hacking up some pipes & buying a bunch of couplers & throwing them onto a 4-banger and claiming it has as much ingeniuty & engineering as a rotary is ludicrous.

Let me ask you these questions:

1: what kind of "y-pipe" did you use? is it an exhaust y-pipe?
2: do you have a dyno sheet yet? "i can feel it making more power" is the lmost common excuse in the book. When I was 17 and wasted money putting a pacesetter exhuast on my protege I thought "it felt faster" too, but guess what.....when I finally got around to dyno'ing it, it made 108whp (with an intake i might add). There was a stock protege at the dyno day too and he made 112whp w/stock exhaust & intake.
