Spectre Intake

[Turbonic]

Part numbers? Especially for the MAF adapter.

I picked these up at a local Autozone, there's a 90 degree bend, a 45 degree bend, and a straight, along with the couplers and filter. I had to customize the straight part to fit the MAF sensor. I tossed all the plastic packaging in the recycling bin after opening, but I can go back and try to get the part #'s if you still need them

Of course we will wait and see. I am just remembering some early attempts (long before the after market intakes came to market) at home made short ram intakes and the results thereof. Hopefully our original poster has some sort of scanning tool to let him know how his work is functioning.

You data log that? I cannot imagine how far of the lift is on your tune... You should really get that checked before posting this on the forums, as members could damage thier engines...

Cobalt guys did this, and found out very quickly why Injen and K&N are more $... Really quickly.

Yes I had my Sonic data logged, and the intake was installed a few minutes before tuning. I went with the full tune with the wideband installed and I can assure you that my car runs safe. Injen, K&N, ZZP, etc. are more expensive because they are metal, are designed specifically for the car, are big name brands, and so on. Just my opinion, I'd love to get an Injen intake later on but I think this Spectre setup is alright

Ahh, the argument of you get what you pay for. Most of the time this is true, but this setup actually looks legit. However, looks can be deceiving. Hopefully it works as good as it looks.

This is a great setup for someone on budget and I recommend it. It works just as good as the name brand intakes, and I have several buddies who have Spectre intakes on their cars and they work fine. The only tricky part is getting the MAF sensor to fit and making brackets for the intake if you don't want it to wobble around. We all had our cars tuned for the intake though.

 

[Turbonic]

In all actuality after a few hours of tuning long term fuel trims were at about 28%! before the intake after some datalogging on the stock intake box we were seeing long terms be around 3%. this pretty much states that after the intake and some tuning on the same boost (this was all a before and after without raising boost) with the new spectre intake we saw nearly 24-25% gain in air flow! id say that is quite a upgrade and not to mention the throttle response is actually 3 times better now!

 

[sonic hotness]

Thats pretty awesome

So how did you get the maf to work

 

[Turbonic]

drill a hole for the maf to be put then then a gasket in the hole of the intake that also goes around the inside of the sensor. no leaks! this is honestly the hardest part of putting the intake together

 

[doreo]

i know for the 1.8 you cannot do this without the tune at all. it will throw a cel and drop hp dramatically and untill about a month ago vince wouldn't even touch it tilll he worked some intake magic the spectre tube is just way to big for the intake vs stock. can it be done now? probably but i would still suggest injin cuz well as ttr said, they are smarter then us.

The question is, how is the MAF sitting?
I haven't looked at how the stocker sits, but if it's in a pipe, the element has to sit in exactly the same placement.

tunes are assuming an exact type of flow around the MAF and if it changes at all it is then inaccurate.

 

[laborsmith]

The MAF is in the pipe which is why you can do anything to the airbox and not throw codes but once you do something to the pipe (replace it with a different diameter or a different length) getting the correct placement becomes tricky.

That's what I thought laborsmith, thanks for the confirmation.

This means that even having it in different bend conditions will affect the numbers, as well as depth/non-centered MAF element placement.
I imagine this is the case and why you're seeing "25% flow improvement".

 

[Turbonic]

with the larger piping, the MAF sensor is actually pretty centered. My bro pulled off the stock intake and said the MAF sensor was nearly touching the wall in there, so if anything that would've been the case with the stock intake. And to think of it: larger piping, larger air filter that breathes easier, and a shorter route to pick up air instead of the ridiculous "snorkel" stock setup could contribute to the 25% better air flow

There is going to be an improvement yes, but I think you might not get why the MAF would behave differently.

If the ECU is tuned for the MAF to be in a certain place in the piping, and that placement changes, the ECU doesn't know that.

A MAF element tells the ECU about airflow by measuring how much voltage it takes to keep the element plate at a specific temperature.
As air flows by the element it cools it then voltage is supplied to heat the plate.
Basically it measures the amount effort it takes to keep things steady.

Placement of the MAF introduces it to other types of turbulence/influences.
So, although it sounds like I'm completely contradicting the ability for the Spectre intake to properly feed air to the motor, I am not.
Gains are certainly possible, but the *only* way to prove exactly what's going on is to test the intake on a machine for verified airflow.
Stock intake gets "x" CFM @ *psi, and Spectre/DDM/ZZP intake gets "y" CFM @ *psi.

Just trying to be as specific as possible when it comes to modifications and claims about anything beyond "It feels stronger".

Didn't have the money to buy a name-brand intake yet, so I settled for this with a tune for now (pretty much the same anyway, only this one's plastic and does not come with any mounts) I had to make the bracket that goes around the second bend and onto the frame so it doesn't wobble around as much, but the filter hits a metal tube that looks like for the air conditioning. There's a rubber hose already around the part where the filter hits, it makes me wonder if the stock airbox touches it. My question here is, and I'm pretty sure I already know what the answer will be, if this is okay? I have some soft foam wrapped around it after I took these pictures and the filter only taps the tube upon startup and besides that just rests on it. I was lifting up the filter in the last picture

you should take a picture of the new maf location. so we can all see exactly what u did to fit the maf on the spectre pipe. looks great btw.

 

[laborsmith]

There is something about how the bracket to steady the intake is attached that I can not put my finger on? Anyone who used the ZZP Cruze Intake see this? Your thoughts please.

[Turbonic]

It's in the same location as the stock and ZZP setups, and like I said, I might go back and make the MAF connection better. But theres no leaks, it doesn't move around and my car runs fine, so I won't mess with it for now

 

[TurboSonicLT]

Looks like a pretty decent setup. Not being a engine tuner myself I would have been a little skeptical about what the ECU might do without a tune. With experience from my 2005 Mustang GT and the MAF meters on them being "overly sesnsitive" to different clocking positions I would recommend anyone trying this mod to be sure that the MAF is clocked to the same position as the OEM installed it. Having a MAF clocked out of position can cause a dangerous lean condition. Most Vendors send countless hours getting around this with tons of data-logging to find the best possible setup....

I am in no way trying to bash your setup, I actually may just do this myself. I just want everyone to understand how sensitive the MAF are to being out of position. Also, great job. Should be a sticky IMO.

As always with any modification... a tune is your best insurance against engine damage, no matter ow small of a change it is!!

 

[ripper806]

Great job man

:banana:

 

[Dragcamaro]

so what is being tuned to compensate for a different maf location? is there like an intake volume input or is the fueling just completely different since there is more/differently read airflow?
I plan on picking up efilive and tuning it myself, which might not happen. Ive tuned a few cars, mostly using BigStuff3 but never anything turbo. Gotta start somewhere.

You're pretty much telling the engine how much air is going in.
