GHETTO custom intake, motor runs but not very good need help!

[jcemitte]

hello all,

ive pieced together a CAI from some cheap plastic tubing i found at the auto parts store. its all rigged up but it runs like shit, it idled like shit and would die so i disconnected the battery and reconnected it and it started to idle and then after a few minutes i could rev it without any lag, i took it on the road and runs but it runs crappy, if i baby the throtle to about 3000rpm and then mash it it takes off, and sounds friggin cool :headbang:, but if i mash it from a dead stop it boggs down really bad. i made sure my MAF was in the right direction and its all sealed up tight and has good air flow through it as far as i can tell. i did adapt it from stock to 3" tubing, so anyone got anything useful for me to try or should i just go back to stock and just save up and buy a damn intake that isnt red neck engineered

Is your MAF in a 3" pipe?

[jcemitte]

yeah the adapter i got for it is 3"

[Bluevitz-rs]

The MAF needs to be inside of a 2.25 inch pipe. The air velocity inside of a 3" pipe doesn't move past the MAF fast enough. So you're starving your engine for fuel. Put it all back to stock, or find a 2.25" MAF adapter or risk doing engine damage from running way too lean.

bluevitz is right

you need a 2.25" pipe

[jcemitte]

bluevitz and barber you guys are the best!!! i couldnt find a 2.25 MAF adapter so i went and got some exhaust pipe that was 2.25 and drilled a hole to fit the sensor and rubber mounted it to seal it off then just bolted the rest up and presto! shes alive! thanks guys woulda definitely been rollin to work stock if it wasn't for you two

I have this in my custom setup:

Hope this helps.

[jcemitte]

woulda helped yesterday lol but hey really cool web site, i am going to convert to that adapter, its a lot better than the one i made.

with this adapter the tubing from Kragen and the air filter the whole thing is about $100 bucks. the $100 DIY CAI is born lol

[Bluevitz-rs]

Why don't you just buy a cheap CAI that's for the car for $100?

[jcemitte]

for $100 bucks i personally get more satisfaction having made it myself, if i was going to buy one i would go with the aEm which is $150 more. im really proud of my Frankenstein intake and the guys at work today thought it was cool too. so yes, buying a cheap CAI would be faster and be a straight bolt on solution, but i learned a lot about my car through this experience and even did some other stuff in the process. so to anyone who doesn't like to tinker i would say just buy one, but if you like to tinker and make things then build one. its really gratifying

I'm just thinking more about power and reliability.

[jcemitte]

bluevitz you drive solid points and admittedly you're right, if that was your goal, which why wouldn't it be right? that was the whole point to being with, power reliability, but what it comes down to is there dyno proven guaranteed CAIs available but i just like the one i made. there is lots of guys that have rolled with their own custom made set ups that have done fine for years.

in conclusion, i think to each their own.

and who knows it may gain just as much as a name brand intake, its more or less the same general idea.
it does pull better than stock

I had a ghetto intake until about 3 weeks, worked great for 4 years, no problems, and helped (along with other mods) get my 107whp (mustang dyno) so ghetto doesn't mean no power or no reliability :thumbsup:

For me a full 2" CAI wasn't enough :thumbsup:

BTW since u already made the MAF custom mounting, why don't u just put the blue rubber connector to the throttle and it'll look nicer. there's no need to use any of the stock rubber thingys :thumbsup:

[Bluevitz-rs]

No that's fine. Most of the people do the same thing with exhaust systems.

i have to buy another piece of pipe for that but good suggestion lol
when she is all put together ill post a pic. that will more than likely be this weekend

Here's my Ghetto setup.

jcemitte,

you should really put a worm clamp around that coupling instead of zip ties. I mean come on a worn clamp cost less that a dollar.

that would make it a $101 intake..... which is unacceptable!
