Scrming's Air Intake Experiment - Part II

[scrming]

Since the IAT relocation experiment went so well, I decided to tackle the intake tube.

Now when I first got my car I had asked Scott from MRT what that big appendage on the left side of the intake tube ways since I had really never seen one like that... He explained it was a silencer/resonator. That it's function was to help eliminate intake noise. And as we all know it does a great job! Even with a K&N filter and the stock snorkel off you cannot hear ANY intake noise!

Scott went on to explain that the silencer/resonator works but it does disrupt the air flow going into the throttle which in turn has a negative effect on performance! Since I don't mind the sucking sound I figured I needed to lose the silencer... First thought was to just cut it off... but I backed off that idea....

So one day walking through the auto parts store I happened to see some universal CAI kits and parts... Hmmm... So I decided to buy some of these parts and see if I could put together my own intake tube.... So I bought a handful of stuff and headed home... and this is what I came up with!

SO...

90 degree elbow, vacuum adapter, 45 degree elbow. I had to cut the 45 degree elbow.



Stock vs new...


The stock silencer/resonator... it's like a figure 8...


The hole for the silencer...


And the hole for the pcv connection... again right before the TB...



and now... the new tube installed.






and finally... a little video clip... (listen with your headphones)

Here's the part list:

Spectre - Air Intake Tube - Part Number: 8698 - $10.00

Spectre - Air Intake Vacuum/Sensor Adapter - Part Number: 8707 - $11.99

Spectre - Air Intake Tube - Part Number: 8738 - $11.99

Spectre - Coupler/Reducer Combo - Part Number: 8771 - $7.99 (2 of them)

Also needed a piece of hose... so basically did this for $50... you may be able to find the piece cheaper online... I just bought them at the local part store...

Big day will be Saturday... Car goes on the dyno! It is a "Dyno Day" though so I'll only get a couple of pulls... unlike when I buy my usual dyno time where I get 4 or 5 pulls... Since I like the way this turned out I'm thinking I will just dyno the IAT relocation and new tube all together....

Looks way better, and probably flows way better.

I used to work in NVH, so I'm very familiar with resonators and the like.

You think that's big though - check my stocker out.

OMG!!! that's crazy! LOL

Yep! It sat underneath the passenger headlight. When I removed it, I thought it sounded nice.

Brian actually thought I had an aftermarket exhaust because of how it sounds inside.

[LSxDreamer]

Looks good and should definitely help out the flow!

[1qwikSS]

looks good...especially for being DIY auto parts stuff.

[scrming]

Thanks guys!

Looking forward to getting some dyno numbers and some time slips! LOL

[00firebird]

you just gave SLP the receipe for their new $250 intake

[meissen]

Looks great - amazing that it only cost you $50!

[scrming]

Thank guys!

Made a video today to double check the movement... see if I have a enough flex with the couplers, etc.

Nice and clean looking

Thanks!

Not 100% sold on the chrome look... it is only chromed plastic... so it may just have to get painted! LOL!

[scrming]

Ok... so the home made intake tube was a FAILURE! The the home intake tube was neck and neck with the stock intake until about 5800 RPM... then home make tube actually MADE LESS POWER! OOPS! The 90 degree turn is going to be the culprit..... if you look at the stock tube it has a nice sweeping turn...

I will get dyno sheets up as soon as I can...

So I give this experiment a thumbs DOWN!

The IAT experiments however did show some promise....

Ok... back to the drawing board! LOL

You could go with a 4" intake tube and then neck it down at the TB. If there's any way you could just put a short piece coming from the TB then to any sensors, and a cone filter routed to the mailslot you'd probably do pretty good that way.

Those motor mounts look pretty soft. For comfort for the people that don't understand it I guess.

Did you check the intakes back to back or just overlaying your last dyno session?
